#initialize(aws_access_key_id = nil, aws_secret_access_key = nil, params = {}) ⇒ S3Interface

Creates new RightS3 instance.

s3 = RightAws::S3Interface.new('1E3GDYEOGFJPIT7XXXXXX','hgTHt68JY07JKUY08ftHYtERkjgtfERn57XXXXXX', {:multi_thread => true, :logger => Logger.new('/tmp/x.log')}) #=> #<RightS3:0xb7b3c27c>

Params is a hash:

If a block is provided, yields incrementally to the block as the response is read. For large responses, this function is ideal as the response can be ‘streamed’.

foo.write(chunk)

#put(bucket, key, data = nil, headers = {}) ⇒ Object

Saves object to Amazon. Returns true or an exception. Any header starting with AMAZON_METADATA_PREFIX is considered user metadata. It will be stored with the object and returned when you retrieve the object. The total size of the HTTP request, not including the body, must be less than 4 KB.

s3.put('my_awesome_bucket', 'log/current/1.log', 'Ola-la!', 'x-amz-meta-family'=>'Woho556!') #=> true

This method is capable of ‘streaming’ uploads; that is, it can upload data from a file or other IO object without first reading all the data into memory. This is most useful for large PUTs - it is difficult to read a 2 GB file entirely into memory before sending it to S3. To stream an upload, pass an object that responds to ‘read’ (like the read method of IO) and to either ‘lstat’ or ‘size’. For files, this means streaming is enabled by simply making the call:

s3.put(bucket_name, 'S3keyname.forthisfile',  File.open('localfilename.dat'))

If the IO object you wish to stream from responds to the read method but doesn’t implement lstat or size, you can extend the object dynamically to implement these methods, or define your own class which defines these methods. Be sure that your class returns ‘nil’ from read() after having read ‘size’ bytes. Otherwise S3 will drop the socket after ‘Content-Length’ bytes have been uploaded, and HttpConnection will interpret this as an error.

This method now supports very large PUTs, where very large is > 2 GB.

For Win32 users: Files and IO objects should be opened in binary mode. If a text mode IO object is passed to PUT, it will be converted to binary mode.
