Parameters:

options (Hash) (defaults to: {}) —

({})

Options Hash (options):

:acl (String) —
The canned access control list (ACL) to apply to the object.

When you copy an object, the ACL metadata is not preserved and is set to ‘private` by default. Only the owner has full access control. To override the default ACL setting, specify a new ACL when you generate a copy request. For more information, see [Using ACLs].

If the destination bucket that you’re copying objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept ‘PUT` requests that don’t specify an ACL or ‘PUT` requests that specify bucket owner full control ACLs, such as the `bucket-owner-full-control` canned ACL or an equivalent form of this ACL expressed in the XML format. For more information, see

Controlling ownership of objects and disabling ACLs][2

in the

*Amazon S3 User Guide*.

<note markdown=“1”> * If your destination bucket uses the bucket owner enforced setting
```
for Object Ownership, all objects written to the bucket by any
account will be owned by the bucket owner.
```
- This functionality is not supported for directory buckets.
- This functionality is not supported for Amazon S3 on Outposts.
```

:cache_control (String) —

Specifies the caching behavior along the request/reply chain.
:checksum_algorithm (String) —
Indicates the algorithm that you want Amazon S3 to use to create the checksum for the object. For more information, see [Checking object integrity] in the *Amazon S3 User Guide*.

When you copy an object, if the source object has a checksum, that checksum value will be copied to the new object by default. If the ‘CopyObject` request does not include this `x-amz-checksum-algorithm` header, the checksum algorithm will be copied from the source object to the destination object (if it’s present on the source object). You can optionally specify a different checksum algorithm to use with the ‘x-amz-checksum-algorithm` header. Unrecognized or unsupported values will respond with the HTTP status code `400 Bad Request`.

<note markdown=“1”> For directory buckets, when you use Amazon Web Services SDKs, ‘CRC32` is the default checksum algorithm that’s used for performance.
```
</note>
```
[1]: docs.aws.amazon.com/AmazonS3/latest/userguide/checking-object-integrity.html
:content_disposition (String) —

Specifies presentational information for the object. Indicates whether an object should be displayed in a web browser or downloaded as a file. It allows specifying the desired filename for the downloaded file.
:content_encoding (String) —
Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.

<note markdown=“1”> For directory buckets, only the ‘aws-chunked` value is supported in this header field.
```
</note>
```
:content_language (String) —

The language the content is in.
:content_type (String) —

A standard MIME type that describes the format of the object data.
:copy_source (required, String) —
Specifies the source object for the copy operation. The source object can be up to 5 GB. If the source object is an object that was uploaded by using a multipart upload, the object copy will be a single part object after the source object is copied to the destination bucket.

You specify the value of the copy source in one of two formats, depending on whether you want to access the source object through an [access point]:
- For objects not accessed through an access point, specify the name of the source bucket and the key of the source object, separated by a slash (/). For example, to copy the object ‘reports/january.pdf` from the general purpose bucket `awsexamplebucket`, use `awsexamplebucket/reports/january.pdf`. The value must be URL-encoded. To copy the object `reports/january.pdf` from the directory bucket `awsexamplebucket–use1-az5–x-s3`, use `awsexamplebucket–use1-az5–x-s3/reports/january.pdf`. The value must be URL-encoded.
- For objects accessed through access points, specify the Amazon Resource Name (ARN) of the object as accessed through the access point, in the format ‘arn:aws:s3:<Region>:<account-id>:accesspoint/<access-point-name>/object/<key>`. For example, to copy the object `reports/january.pdf` through access point `my-access-point` owned by account `123456789012` in Region `us-west-2`, use the URL encoding of `arn:aws:s3:us-west-2:123456789012:accesspoint/my-access-point/object/reports/january.pdf`. The value must be URL encoded.
  
  <note markdown=“1”> * Amazon S3 supports copy operations using Access points only when
```
the source and destination buckets are in the same Amazon Web
Services Region.
```
  - Access points are not supported by directory buckets.
```
</note>
```
  Alternatively, for objects accessed through Amazon S3 on Outposts, specify the ARN of the object as accessed in the format ‘arn:aws:s3-outposts:<Region>:<account-id>:outpost/<outpost-id>/object/<key>`. For example, to copy the object `reports/january.pdf` through outpost `my-outpost` owned by account `123456789012` in Region `us-west-2`, use the URL encoding of `arn:aws:s3-outposts:us-west-2:123456789012:outpost/my-outpost/object/reports/january.pdf`. The value must be URL-encoded.
If your source bucket versioning is enabled, the ‘x-amz-copy-source` header by default identifies the current version of an object to copy. If the current version is a delete marker, Amazon S3 behaves as if the object was deleted. To copy a different version, use the `versionId` query parameter. Specifically, append `?versionId=<version-id>` to the value (for example, `awsexamplebucket/reports/january.pdf?versionId=QUpfdndhfd8438MNFDN93jdnJFkdmqnh893`). If you don’t specify a version ID, Amazon S3 copies the latest version of the source object.

If you enable versioning on the destination bucket, Amazon S3 generates a unique version ID for the copied object. This version ID is different from the version ID of the source object. Amazon S3 returns the version ID of the copied object in the ‘x-amz-version-id` response header in the response.

If you do not enable versioning or suspend it on the destination bucket, the version ID that Amazon S3 generates in the ‘x-amz-version-id` response header is always null.

<note markdown=“1”> **Directory buckets** - S3 Versioning isn’t enabled and supported for directory buckets.

:copy_source_if_match (String) —
Copies the object if its entity tag (ETag) matches the specified tag.

If both the ‘x-amz-copy-source-if-match` and `x-amz-copy-source-if-unmodified-since` headers are present in the request and evaluate as follows, Amazon S3 returns `200 OK` and copies the data:
- ‘x-amz-copy-source-if-match` condition evaluates to true
- ‘x-amz-copy-source-if-unmodified-since` condition evaluates to false
:copy_source_if_modified_since (Time, DateTime, Date, Integer, String) —
Copies the object if it has been modified since the specified time.

If both the ‘x-amz-copy-source-if-none-match` and `x-amz-copy-source-if-modified-since` headers are present in the request and evaluate as follows, Amazon S3 returns the `412 Precondition Failed` response code:
- ‘x-amz-copy-source-if-none-match` condition evaluates to false
- ‘x-amz-copy-source-if-modified-since` condition evaluates to true
:copy_source_if_none_match (String) —
Copies the object if its entity tag (ETag) is different than the specified ETag.

If both the ‘x-amz-copy-source-if-none-match` and `x-amz-copy-source-if-modified-since` headers are present in the request and evaluate as follows, Amazon S3 returns the `412 Precondition Failed` response code:
- ‘x-amz-copy-source-if-none-match` condition evaluates to false
- ‘x-amz-copy-source-if-modified-since` condition evaluates to true
:copy_source_if_unmodified_since (Time, DateTime, Date, Integer, String) —
Copies the object if it hasn’t been modified since the specified time.

If both the ‘x-amz-copy-source-if-match` and `x-amz-copy-source-if-unmodified-since` headers are present in the request and evaluate as follows, Amazon S3 returns `200 OK` and copies the data:
- ‘x-amz-copy-source-if-match` condition evaluates to true
- ‘x-amz-copy-source-if-unmodified-since` condition evaluates to false
:expires (Time, DateTime, Date, Integer, String) —

The date and time at which the object is no longer cacheable.
:grant_full_control (String) —
Gives the grantee READ, READ_ACP, and WRITE_ACP permissions on the object.

```
:metadata (Hash<String,String>) —

A map of metadata to store with the object in S3.
:metadata_directive (String) —
Specifies whether the metadata is copied from the source object or replaced with metadata that’s provided in the request. When copying an object, you can preserve all metadata (the default) or specify new metadata. If this header isn’t specified, ‘COPY` is the default behavior.

**General purpose bucket** - For general purpose buckets, when you grant permissions, you can use the ‘s3:x-amz-metadata-directive` condition key to enforce certain metadata behavior when objects are uploaded. For more information, see [Amazon S3 condition key examples] in the *Amazon S3 User Guide*.

<note markdown=“1”> ‘x-amz-website-redirect-location` is unique to each object and is not copied when using the `x-amz-metadata-directive` header. To copy the value, you must specify `x-amz-website-redirect-location` in the request header.
```
</note>
```
[1]: docs.aws.amazon.com/AmazonS3/latest/dev/amazon-s3-policy-keys.html
:tagging_directive (String) —
Specifies whether the object tag-set is copied from the source object or replaced with the tag-set that’s provided in the request.

The default value is ‘COPY`.

<note markdown=“1”> **Directory buckets** - For directory buckets in a ‘CopyObject` operation, only the empty tag-set is supported. Any requests that attempt to write non-empty tags into directory buckets will receive a `501 Not Implemented` status code. When the destination bucket is a directory bucket, you will receive a `501 Not Implemented` response in any of the following situations:
```
* When you attempt to `COPY` the tag-set from an S3 source object that
 has non-empty tags.
```
- When you attempt to ‘REPLACE` the tag-set of a source object and set a non-empty value to `x-amz-tagging`.
- When you don’t set the ‘x-amz-tagging-directive` header and the source object has non-empty tags. This is because the default value of `x-amz-tagging-directive` is `COPY`.
```
Because only the empty tag-set is supported for directory buckets in a
```
‘CopyObject` operation, the following situations are allowed:
```
* When you attempt to `COPY` the tag-set from a directory bucket
 source object that has no tags to a general purpose bucket. It
 copies an empty tag-set to the destination object.
```
- When you attempt to ‘REPLACE` the tag-set of a directory bucket source object and set the `x-amz-tagging` value of the directory bucket destination object to empty.
- When you attempt to ‘REPLACE` the tag-set of a general purpose bucket source object that has non-empty tags and set the `x-amz-tagging` value of the directory bucket destination object to empty.
- When you attempt to ‘REPLACE` the tag-set of a directory bucket source object and don’t set the ‘x-amz-tagging` value of the directory bucket destination object. This is because the default value of `x-amz-tagging` is the empty value.
```
</note>
```
:server_side_encryption (String) —
The server-side encryption algorithm used when storing this object in Amazon S3 (for example, ‘AES256`, `aws:kms`, `aws:kms:dsse`). Unrecognized or unsupported values won’t write a destination object and will receive a `400 Bad Request` response.

Amazon S3 automatically encrypts all new objects that are copied to an S3 bucket. When copying an object, if you don’t specify encryption information in your copy request, the encryption setting of the target object is set to the default encryption configuration of the destination bucket. By default, all buckets have a base level of encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). If the destination bucket has a default encryption configuration that uses server-side encryption with Key Management Service (KMS) keys (SSE-KMS), dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS), or server-side encryption with customer-provided encryption keys (SSE-C), Amazon S3 uses the corresponding KMS key, or a customer-provided key to encrypt the target object copy.

When you perform a ‘CopyObject` operation, if you want to use a different type of encryption setting for the target object, you can specify appropriate encryption-related headers to encrypt the target object with an Amazon S3 managed key, a KMS key, or a customer-provided key. If the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence.

With server-side encryption, Amazon S3 encrypts your data as it writes your data to disks in its data centers and decrypts the data when you access it. For more information about server-side encryption, see

Using Server-Side Encryption][1

in the *Amazon S3 User Guide*.

<note markdown=“1”> For directory buckets, only server-side encryption with Amazon S3 managed keys (SSE-S3) (‘AES256`) is supported.
```
</note>

:storage_class (String) —
If the ‘x-amz-storage-class` header is not used, the copied object will be stored in the `STANDARD` Storage Class by default. The `STANDARD` storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class.

<note markdown=“1”> * Directory buckets - For directory buckets, only the S3
```
Express One Zone storage class is supported to store newly created
objects. Unsupported storage class values won't write a destination
object and will respond with the HTTP status code `400 Bad Request`.
```
- Amazon S3 on Outposts - S3 on Outposts only uses the ‘OUTPOSTS` Storage Class.
```
</note>
```
You can use the ‘CopyObject` action to change the storage class of an object that is already stored in Amazon S3 by using the `x-amz-storage-class` header. For more information, see [Storage Classes] in the *Amazon S3 User Guide*.

Before using an object as a source object for the copy operation, you must restore a copy of it if it meets any of the following conditions:
- The storage class of the source object is ‘GLACIER` or `DEEP_ARCHIVE`.
- The storage class of the source object is ‘INTELLIGENT_TIERING` and it’s [S3 Intelligent-Tiering access tier] is ‘Archive Access` or `Deep Archive Access`.
For more information, see [RestoreObject] and [Copying Objects] in the *Amazon S3 User Guide*.

:website_redirect_location (String) —
If the destination bucket is configured as a website, redirects requests for this object copy to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. This value is unique to each object and is not copied when using the ‘x-amz-metadata-directive` header. Instead, you may opt to provide this header in combination with the `x-amz-metadata-directive` header.

<note markdown=“1”> This functionality is not supported for directory buckets.
```
</note>
```
:sse_customer_algorithm (String) —
Specifies the algorithm to use when encrypting the object (for example, ‘AES256`).

When you perform a ‘CopyObject` operation, if you want to use a different type of encryption setting for the target object, you can specify appropriate encryption-related headers to encrypt the target object with an Amazon S3 managed key, a KMS key, or a customer-provided key. If the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence.

<note markdown=“1”> This functionality is not supported when the destination bucket is a directory bucket.
```
</note>
```
:sse_customer_key (String) —
Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded. Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the ‘x-amz-server-side-encryption-customer-algorithm` header.

<note markdown=“1”> This functionality is not supported when the destination bucket is a directory bucket.
```
</note>
```
:sse_customer_key_md5 (String) —
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

<note markdown=“1”> This functionality is not supported when the destination bucket is a directory bucket.
```
</note>
```
:ssekms_key_id (String) —
Specifies the KMS ID (Key ID, Key ARN, or Key Alias) to use for object encryption. All GET and PUT requests for an object protected by KMS will fail if they’re not made via SSL or using SigV4. For information about configuring any of the officially supported Amazon Web Services SDKs and Amazon Web Services CLI, see [Specifying the Signature Version in Request Authentication] in the *Amazon S3 User Guide*.

<note markdown=“1”> This functionality is not supported when the destination bucket is a directory bucket.
```
</note>
```
[1]: docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html#specify-signature-version
:ssekms_encryption_context (String) —
Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs. This value must be explicitly added to specify encryption context for ‘CopyObject` requests.

<note markdown=“1”> This functionality is not supported when the destination bucket is a directory bucket.
```
</note>
```
:bucket_key_enabled (Boolean) —
Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using Key Management Service (KMS) keys (SSE-KMS). If a target object uses SSE-KMS, you can enable an S3 Bucket Key for the object.

Setting this header to ‘true` causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS. Specifying this header with a COPY action doesn’t affect bucket-level settings for S3 Bucket Key.

For more information, see [Amazon S3 Bucket Keys] in the *Amazon S3 User Guide*.

<note markdown=“1”> This functionality is not supported when the destination bucket is a directory bucket.
```
</note>
```
[1]: docs.aws.amazon.com/AmazonS3/latest/dev/bucket-key.html
:copy_source_sse_customer_algorithm (String) —
Specifies the algorithm to use when decrypting the source object (for example, ‘AES256`).

If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying.

<note markdown=“1”> This functionality is not supported when the source object is in a directory bucket.
```
</note>
```
:copy_source_sse_customer_key (String) —
Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided in this header must be the same one that was used when the source object was created.

If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying.

<note markdown=“1”> This functionality is not supported when the source object is in a directory bucket.
```
</note>
```
:copy_source_sse_customer_key_md5 (String) —
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying.

<note markdown=“1”> This functionality is not supported when the source object is in a directory bucket.
```
</note>
```
:request_payer (String) —
Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see [Downloading Objects in Requester Pays Buckets] in the *Amazon S3 User Guide*.

<note markdown=“1”> This functionality is not supported for directory buckets.
```
</note>
```
[1]: docs.aws.amazon.com/AmazonS3/latest/dev/ObjectsinRequesterPaysBuckets.html
:tagging (String) —
The tag-set for the object copy in the destination bucket. This value must be used in conjunction with the ‘x-amz-tagging-directive` if you choose `REPLACE` for the `x-amz-tagging-directive`. If you choose `COPY` for the `x-amz-tagging-directive`, you don’t need to set the ‘x-amz-tagging` header, because the tag-set will be copied from the source object directly. The tag-set must be encoded as URL Query parameters.

The default value is the empty value.

<note markdown=“1”> **Directory buckets** - For directory buckets in a ‘CopyObject` operation, only the empty tag-set is supported. Any requests that attempt to write non-empty tags into directory buckets will receive a `501 Not Implemented` status code. When the destination bucket is a directory bucket, you will receive a `501 Not Implemented` response in any of the following situations:
```
* When you attempt to `COPY` the tag-set from an S3 source object that
 has non-empty tags.
```
- When you attempt to ‘REPLACE` the tag-set of a source object and set a non-empty value to `x-amz-tagging`.
- When you don’t set the ‘x-amz-tagging-directive` header and the source object has non-empty tags. This is because the default value of `x-amz-tagging-directive` is `COPY`.
```
Because only the empty tag-set is supported for directory buckets in a
```
‘CopyObject` operation, the following situations are allowed:
```
* When you attempt to `COPY` the tag-set from a directory bucket
 source object that has no tags to a general purpose bucket. It
 copies an empty tag-set to the destination object.
```
- When you attempt to ‘REPLACE` the tag-set of a directory bucket source object and set the `x-amz-tagging` value of the directory bucket destination object to empty.
- When you attempt to ‘REPLACE` the tag-set of a general purpose bucket source object that has non-empty tags and set the `x-amz-tagging` value of the directory bucket destination object to empty.
- When you attempt to ‘REPLACE` the tag-set of a directory bucket source object and don’t set the ‘x-amz-tagging` value of the directory bucket destination object. This is because the default value of `x-amz-tagging` is the empty value.
```
</note>
```
:object_lock_mode (String) —

You may provide a `on_checksum_validated` callback if you need to verify that validation occurred and which algorithm was used. To disable checksum validation, set `checksum_mode` to “DISABLED”.
on_checksum_validated (Callable) —

Called each time a request’s checksum is validated with the checksum algorithm and the response. For multipart downloads, this will be called for each part that is downloaded and validated.
:progress_callback (Proc) —

A Proc that will be called when each chunk of the download is received. It will be invoked with [bytes_read], [part_sizes], file_size. When the object is downloaded as parts (rather than by ranges), the part_sizes will not be known ahead of time and will be nil in the callback until the first bytes in the part are received.

Options Hash (options):

:acl (String) —
The canned ACL to apply to the object. Amazon S3 supports a set of predefined ACLs, known as *canned ACLs*. Each canned ACL has a predefined set of grantees and permissions. For more information, see

Canned ACL][1

in the *Amazon S3 User Guide*.

By default, all objects are private. Only the owner has full access control. When uploading an object, you can grant access permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the access control list (ACL) on the new object. For more information, see [Using ACLs]. One way to grant the permissions using the request headers is to specify a canned ACL with the ‘x-amz-acl` request header.

```
</note>
```
:content_language (String) —

The language that the content is in.
:content_type (String) —

A standard MIME type describing the format of the object data.
:expires (Time, DateTime, Date, Integer, String) —

:grant_full_control (String) —
Specify access permissions explicitly to give the grantee READ, READ_ACP, and WRITE_ACP permissions on the object.

By default, all objects are private. Only the owner has full access control. When uploading an object, you can use this header to explicitly grant access permissions to specific Amazon Web Services accounts or groups. This header maps to specific permissions that Amazon S3 supports in an ACL. For more information, see [Access Control List (ACL) Overview] in the *Amazon S3 User Guide*.

You specify each grantee as a type=value pair, where the type is one of the following:
- ‘id` – if the value specified is the canonical user ID of an Amazon Web Services account
- ‘uri` – if you are granting permissions to a predefined group
- ‘emailAddress` – if the value specified is the email address of an Amazon Web Services account
  
  <note markdown=“1”> Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

#presigned_request(method, params = {}) ⇒ `String`, `Hash`

Allows you to create presigned URL requests for S3 operations. This method returns a tuple containing the URL and the signed X-amz-* headers to be used with the presigned url.

Examples:

Pre-signed GET URL, valid for one hour


obj.presigned_request(:get, expires_in: 3600)
#=> ["https://bucket-name.s3.amazonaws.com/object-key?...", {}]

Pre-signed PUT with a canned ACL


# the object uploaded using this URL will be publicly accessible
obj.presigned_request(:put, acl: 'public-read')
#=> ["https://bucket-name.s3.amazonaws.com/object-key?...",
 {"x-amz-acl"=>"public-read"}]

Parameters:

method (Symbol) —

The S3 operation to generate a presigned request for. Valid values are ‘:get`, `:put`, `:head`, `:delete`, `:create_multipart_upload`, `:list_multipart_uploads`, `:complete_multipart_upload`, `:abort_multipart_upload`, `:list_parts`, and `:upload_part`.
params (Hash) (defaults to: {}) —

Additional request parameters to use when generating the pre-signed request. See the related documentation in Client for accepted params.

| Method | Client Method | |——————————|————————————| | ‘:get` | Client#get_object | | `:put` | Client#put_object | | `:head` | Client#head_object | | `:delete` | Client#delete_object | | `:create_multipart_upload` | Client#create_multipart_upload | | `:list_multipart_uploads` | Client#list_multipart_uploads | | `:complete_multipart_upload` | Client#complete_multipart_upload | | `:abort_multipart_upload` | Client#abort_multipart_upload | | `:list_parts` | Client#list_parts | | `:upload_part` | Client#upload_part |

Options Hash (params):

:virtual_host (Boolean) — default: false —

Parameters:

options (Hash) (defaults to: {}) —

({})

Options Hash (options):

:acl (String) —
The canned ACL to apply to the object. For more information, see

Canned ACL][1

in the *Amazon S3 User Guide*.

When adding a new object, you can use headers to grant ACL-based permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. By default, all objects are private. Only the owner has full access control. For more information, see

Access Control List (ACL) Overview][2

and [Managing ACLs Using the

REST API] in the *Amazon S3 User Guide*.

If the bucket that you’re uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don’t specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the ‘bucket-owner-full-control` canned ACL or an equivalent form of this ACL expressed in the XML format. PUT requests that contain other ACLs (for example, custom grants to certain Amazon Web Services accounts) fail and return a `400` error with the error code `AccessControlListNotSupported`. For more information, see [ Controlling ownership of objects and disabling ACLs] in the *Amazon S3 User Guide*.

:body (String, StringIO, File) —

Object data.
:cache_control (String) —

[1]: www.rfc-editor.org/rfc/rfc6266#section-4
:content_encoding (String) —

Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field. For more information, see [www.rfc-editor.org/rfc/rfc9110.html#field.content-encoding][1].

[1]: www.rfc-editor.org/rfc/rfc9110.html#field.content-encoding
:content_language (String) —

The language the content is in.
:content_length (Integer) —

Size of the body in bytes. This parameter is useful when the size of the body cannot be determined automatically. For more information, see [www.rfc-editor.org/rfc/rfc9110.html#name-content-length][1].

[1]: www.rfc-editor.org/rfc/rfc9110.html#name-content-length
:content_md5 (String) —
The base64-encoded 128-bit MD5 digest of the message (without the headers) according to RFC 1864. This header can be used as a message integrity check to verify that the data is the same data that was originally sent. Although it is optional, we recommend using the Content-MD5 mechanism as an end-to-end integrity check. For more information about REST request authentication, see [REST Authentication].

<note markdown=“1”> The ‘Content-MD5` header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see [Amazon S3 Object Lock Overview] in the *Amazon S3 User Guide*.

:content_type (String) —

A standard MIME type describing the format of the contents. For more information, see [www.rfc-editor.org/rfc/rfc9110.html#name-content-type][1].

[1]: www.rfc-editor.org/rfc/rfc9110.html#name-content-type
:checksum_algorithm (String) —
Indicates the algorithm used to create the checksum for the object when you use the SDK. This header will not provide any additional functionality if you don’t use the SDK. When you send this header, there must be a corresponding ‘x-amz-checksum-algorithm ` or `x-amz-trailer` header sent. Otherwise, Amazon S3 fails the request with the HTTP status code `400 Bad Request`.

For the ‘x-amz-checksum-algorithm ` header, replace ` algorithm ` with the supported algorithm from the following list:
- CRC32
- CRC32C
- SHA1
- SHA256
For more information, see [Checking object integrity] in the *Amazon S3 User Guide*.

If the individual checksum value you provide through ‘x-amz-checksum-algorithm ` doesn’t match the checksum algorithm you set through ‘x-amz-sdk-checksum-algorithm`, Amazon S3 ignores any provided `ChecksumAlgorithm` parameter and uses the checksum algorithm that matches the provided value in `x-amz-checksum-algorithm `.

<note markdown=“1”> For directory buckets, when you use Amazon Web Services SDKs, ‘CRC32` is the default checksum algorithm that’s used for performance.
```

:server_side_encryption (String) —

The server-side encryption algorithm that was used when you store this object in Amazon S3 (for example, ‘AES256`, `aws:kms`, `aws:kms:dsse`).

General purpose buckets - You have four mutually exclusive options to protect data using server-side encryption in Amazon S3, depending on how you choose to manage the encryption keys. Specifically, the encryption key options are Amazon S3 managed keys (SSE-S3), Amazon Web Services KMS keys (SSE-KMS or DSSE-KMS), and customer-provided keys (SSE-C). Amazon S3 encrypts data with server-side encryption by using Amazon S3 managed keys (SSE-S3) by default. You can optionally tell Amazon S3 to encrypt data at rest by using server-side encryption with other key options. For more information, see [Using Server-Side Encryption] in the *Amazon S3 User Guide*.

Directory buckets - For directory buckets, only the server-side encryption with Amazon S3 managed keys (SSE-S3) (‘AES256`) value is supported.

By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. For more information, see [Storage Classes] in the *Amazon S3 User Guide*.

<note markdown=“1”> * For directory buckets, only the S3 Express One Zone storage class is
```
supported to store newly created objects.
```
- Amazon S3 on Outposts only uses the OUTPOSTS Storage Class.
```

:website_redirect_location (String) —
If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. For information about object metadata, see [Object Key and Metadata] in the *Amazon S3 User Guide*.

In the following example, the request header sets the redirect to an object (anotherPage.html) in the same bucket:

‘x-amz-website-redirect-location: /anotherPage.html`

In the following example, the request header sets the object redirect to another website:

‘x-amz-website-redirect-location: www.example.com/`

For more information about website hosting in Amazon S3, see [Hosting Websites on Amazon S3] and [How to Configure Website Page Redirects] in the *Amazon S3 User Guide*.

:sse_customer_algorithm (String) —
Specifies the algorithm to use when encrypting the object (for example, ‘AES256`).

<note markdown=“1”> This functionality is not supported for directory buckets.
```
</note>
```
:sse_customer_key (String) —
Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the ‘x-amz-server-side-encryption-customer-algorithm` header.

<note markdown=“1”> This functionality is not supported for directory buckets.
```
</note>
```
:sse_customer_key_md5 (String) —
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

<note markdown=“1”> This functionality is not supported for directory buckets.
```
</note>
```
:ssekms_key_id (String) —
If ‘x-amz-server-side-encryption` has a valid value of `aws:kms` or `aws:kms:dsse`, this header specifies the ID (Key ID, Key ARN, or Key Alias) of the Key Management Service (KMS) symmetric encryption customer managed key that was used for the object. If you specify `x-amz-server-side-encryption:aws:kms` or `x-amz-server-side-encryption:aws:kms:dsse`, but do not provide` x-amz-server-side-encryption-aws-kms-key-id`, Amazon S3 uses the Amazon Web Services managed key (`aws/s3`) to protect the data. If the KMS key does not exist in the same account that’s issuing the command, you must use the full ARN and not just the ID.

<note markdown=“1”> This functionality is not supported for directory buckets.
```
</note>
```
:ssekms_encryption_context (String) —
Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs. This value is stored as object metadata and automatically gets passed on to Amazon Web Services KMS for future ‘GetObject` or `CopyObject` operations on this object. This value must be explicitly added during `CopyObject` operations.

<note markdown=“1”> This functionality is not supported for directory buckets.
```
</note>
```
:bucket_key_enabled (Boolean) —
Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using Key Management Service (KMS) keys (SSE-KMS). Setting this header to ‘true` causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

Specifying this header with a PUT action doesn’t affect bucket-level settings for S3 Bucket Key.

<note markdown=“1”> This functionality is not supported for directory buckets.
```
</note>
```
:request_payer (String) —
Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see [Downloading Objects in Requester Pays Buckets] in the *Amazon S3 User Guide*.

```
</note>
```
[1]: docs.aws.amazon.com/AmazonS3/latest/dev/object-lock.html
:expected_bucket_owner (String) —

The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code ‘403 Forbidden` (access denied).

Returns:

(Types::PutObjectOutput)

# File 'lib/aws-sdk-s3/object.rb', line 2622

def put(options = {})
  options = options.merge(
    bucket: @bucket_name,

  end
  resp.data
end

#replication_status ⇒ `String`

Amazon S3 can return this header if your request involves a bucket that is either a source or a destination in a replication rule.

In replication, you have a source bucket on which you configure replication and destination bucket or buckets where Amazon S3 stores object replicas. When you request an object (‘GetObject`) or object metadata (`HeadObject`) from these buckets, Amazon S3 will return the `x-amz-replication-status` header in the response as follows:

**If requesting an object from the source bucket**, Amazon S3 will return the ‘x-amz-replication-status` header if the object in your request is eligible for replication.

For example, suppose that in your replication configuration, you specify object prefix ‘TaxDocs` requesting Amazon S3 to replicate objects with key prefix `TaxDocs`. Any objects you upload with this key name prefix, for example `TaxDocs/document1.pdf`, are eligible for replication. For any object request with this key name prefix, Amazon S3 will return the `x-amz-replication-status` header with value PENDING, COMPLETED or FAILED indicating object replication status.
**If requesting an object from a destination bucket**, Amazon S3 will return the ‘x-amz-replication-status` header with value REPLICA if the object in your request is a replica that Amazon S3 created and there is no replica modification replication in progress.
**When replicating objects to multiple destination buckets**, the ‘x-amz-replication-status` header acts differently. The header of the source object will only return a value of COMPLETED when replication is successful to all destinations. The header will remain at value PENDING until replication has completed for all destinations. If one or more destinations fails replication the header will return FAILED.

For more information, see [Replication].

#restore ⇒ `String`

If the object is an archived object (an object whose storage class is GLACIER), the response includes this header if either the archive restoration is in progress (see [RestoreObject] or an archive copy is already restored.

If an archive copy is already restored, the header value indicates when Amazon S3 is scheduled to delete the object copy. For example:

‘x-amz-restore: ongoing-request=“false”, expiry-date=“Fri, 21 Dec 2012 00:00:00 GMT”`

If the object restoration is in progress, the header returns the value ‘ongoing-request=“true”`.

#upload_file(source, options = {}) {|response| ... } ⇒ `Boolean`

Uploads a file from disk to the current object in S3.

# small files are uploaded in a single API call
obj.upload_file('/path/to/file')

Files larger than or equal to ‘:multipart_threshold` are uploaded using the Amazon S3 multipart upload APIs.

# large files are automatically split into parts
# and the parts are uploaded in parallel
obj.upload_file('/path/to/very_large_file')

The response of the S3 upload API is yielded if a block given.

# API response will have etag value of the file
obj.upload_file('/path/to/file') do |response|
  etag = response.etag
end

You can provide a callback to monitor progress of the upload:

# bytes and totals are each an array with 1 entry per part
progress = Proc.new do |bytes, totals|
  puts bytes.map.with_index { |b, i| "Part #{i+1}: #{b} / #{totals[i]}"}.join(' ') + "Total: #{100.0 * bytes.sum / totals.sum }%" }
end
obj.upload_file('/path/to/file', progress_callback: progress)

Parameters:

source (String, Pathname, File, Tempfile) —

A file on the local file system that will be uploaded as this object. This can either be a String or Pathname to the file, an open File object, or an open Tempfile object. If you pass an open File or Tempfile object, then you are responsible for closing it after the upload completes. When using an open Tempfile, rewind it before uploading or else the object will be empty.
options (Hash) (defaults to: {}) —

Additional options for Client#put_object when file sizes below the multipart threshold. For files larger than the multipart threshold, options for Client#create_multipart_upload, Client#complete_multipart_upload, and Client#upload_part can be provided.

Options Hash (options):

:multipart_threshold (Integer) — default: 104857600 —

Files larger than or equal to ‘:multipart_threshold` are uploaded using the S3 multipart APIs. Default threshold is 100MB.
:thread_count (Integer) — default: 10 —

The number of parallel multipart uploads. This option is not used if the file is smaller than ‘:multipart_threshold`.
:progress_callback (Proc) —

A Proc that will be called when each chunk of the upload is sent. It will be invoked with [bytes_read], [total_sizes]

Yields:

(response)

Returns:

(Boolean) —

Returns ‘true` when the object is uploaded without any errors.

Raises:

(MultipartUploadError) —

If an object is being uploaded in parts, and the upload can not be completed, then the upload is aborted and this error is raised. The raised error has a ‘#errors` method that returns the failures that caused the upload to be aborted.

    )
  end
  yield response if block_given?
  true
end

#upload_stream(options = {}, &block) ⇒ `Boolean`

Uploads a stream in a streaming fashion to the current object in S3.

Passed chunks automatically split into multipart upload parts and the parts are uploaded in parallel. This allows for streaming uploads that never touch the disk.

Note that this is known to have issues in JRuby until jruby-9.1.15.0, so avoid using this with older versions of JRuby.

Examples:

Streaming chunks of data

obj.upload_stream do |write_stream|
  10.times { write_stream << 'foo' }
end

Streaming chunks of data

obj.upload_stream do |write_stream|
  IO.copy_stream(IO.popen('ls'), write_stream)
end

Streaming chunks of data

obj.upload_stream do |write_stream|
  IO.copy_stream(STDIN, write_stream)
end

Parameters:

options (Hash) (defaults to: {}) —

Additional options for Client#create_multipart_upload, Client#complete_multipart_upload, and Client#upload_part can be provided.

Options Hash (options):

:thread_count (Integer) — default: 10 —

The number of parallel multipart uploads
:tempfile (Boolean) — default: false —

Normally read data is stored in memory when building the parts in order to complete the underlying multipart upload. By passing ‘:tempfile => true` data read will be temporarily stored on disk reducing the memory footprint vastly.
:part_size (Integer) — default: 5242880 —

Define how big each part size but the last should be. Default ‘:part_size` is `5 * 1024 * 1024`.

Returns:

(Boolean) —

Returns ‘true` when the object is uploaded without any errors.

Raises:

(MultipartUploadError) —

If an object is being uploaded in parts, and the upload can not be completed, then the upload is aborted and this error is raised. The raised error has a ‘#errors` method that returns the failures that caused the upload to be aborted.

#wait_until(options = {}) {|resource| ... } ⇒ `Resource`

Deprecated.

Use [Aws::S3::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

## Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

## Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

## Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

## Callbacks

You can be notified before each polling attempt and before each delay. If you throw ‘:success` or `:failure` from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

## Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

options (Hash) (defaults to: {}) —

a customizable set of options

Options Hash (options):

:max_attempts (Integer) — default: 10 —

Maximum number of
:delay (Integer) — default: 10 —
