#media(path) ⇒ Object
Returns a direct link to a media file All of Dropbox’s API methods require OAuth, which may cause problems in situations where an application expects to be able to hit a URL multiple times (for example, a media player seeking around a video file). This method creates a time-limited URL that can be accessed without any authentication.
Arguments:
-
path: The file to stream.
Returns:
-
A Hash object that looks like the following:
{'url': 'https://dl.dropbox.com/0/view/wvxv1fw6on24qw7/file.mov', 'expires': 'Thu, 16 Sep 2011 01:01:25 +0000'}

#metadata(path, file_limit = 10000, list = true, hash = nil) ⇒ Object
Retrives metadata for a file or folder
Arguments:
-
path: The path to the file or folder.
-
list: Whether to list all contained files (only applies when path refers to a folder).
-
file_limit: The maximum number of file entries to return within a folder. If the number of files in the directory exceeds this limit, an exception is raised. The server will return at max 10,000 files within a folder.
-
hash: Every directory listing has a hash parameter attached that can then be passed back into this function later to save on bandwidth. Rather than returning an unchanged folder’s contents, if the hash matches a DropboxNotModified exception is raised.
Returns:
-
A Hash object with the metadata of the file or folder (and contained files if appropriate). For a detailed description of what this call returns, visit: www.dropbox.com/developers/docs#metadata

#parse_response(response, raw = false) ⇒ Object

#put_file(to_path, file_obj, overwrite = false, parent_rev = nil) ⇒ Object
Uploads a file to a server. This uses the HTTP PUT upload method for simplicity
Arguments:
-
to_path: The directory path to upload the file to. If the destination directory does not yet exist, it will be created.
-
file_obj: A file-like object to upload. If you would like, you can pass a string as file_obj.
-
overwrite: Whether to overwrite an existing file at the given path. [default is False] If overwrite is False and a file already exists there, Dropbox will rename the upload to make sure it doesn’t overwrite anything. You must check the returned metadata to know what this new name is. This field should only be True if your intent is to potentially clobber changes to a file that you don’t know about.
-
parent_rev: The rev field from the ‘parent’ of this upload. [optional] If your intent is to update the file at the given path, you should pass the parent_rev parameter set to the rev value from the most recent metadata you have of the existing file at that path. If the server has a more recent version of the file at the specified path, it will automatically rename your uploaded file, spinning off a conflict. Using this parameter effectively causes the overwrite parameter to be ignored. The file will always be overwritten if you send the most-recent parent_rev, and it will never be overwritten you send a less-recent one.
Returns:
-
a Hash containing the metadata of the newly uploaded file. The file may have a different name if it conflicted.
Simple Example
client = DropboxClient(session, :app_folder)
#session is a DropboxSession I've already authorized
client.put_file('/test_file_on_dropbox', open('/tmp/test_file'))
This will upload the “/tmp/test_file” from my computer into the root of my App’s app folder and call it “test_file_on_dropbox”. The file will not overwrite any pre-existing file.

#shares(path) ⇒ Object
Get a URL to share a media file Shareable links created on Dropbox are time-limited, but don’t require any authentication, so they can be given out freely. The time limit should allow at least a day of shareability, though users have the ability to disable a link from their account if they like.
