`GDataService provides CRUD ops. and programmatic login for GData services.
Error: A base exception class for all exceptions in the gdata_client
module.
CaptchaRequired: This exception is thrown when a login attempt results in a
captcha challenge from the ClientLogin service. When this
exception is thrown, the captcha_token and captcha_url are
set to the values provided in the server's response.
BadAuthentication: Raised when a login attempt is made with an incorrect
username or password.
NotAuthenticated: Raised if an operation requiring authentication is called
before a user has authenticated.
NonAuthSubToken: Raised if a method to modify an AuthSub token is used when
the user is either not authenticated or is authenticated
through another authentication mechanism.
NonOAuthToken: Raised if a method to modify an OAuth token is used when the
user is either not authenticated or is authenticated through
another authentication mechanism.
RequestError: Raised if a CRUD request returned a non-success code.
UnexpectedReturnType: Raised if the response from the server was not of the
desired type. For example, this would be raised if the
server sent a feed when the client requested an entry.
GDataService: Encapsulates user credentials needed to perform insert, update
and delete operations with the GData API. An instance can
perform user authentication, query, insertion, deletion, and
update.
Query: Eases query URI creation by allowing URI parameters to be set as
dictionary attributes. For example a query with a feed of
'/base/feeds/snippets' and ['bq'] set to 'digital camera' will
produce '/base/feeds/snippets?bq=digital+camera' when .ToUri() is
called on it.`

Example: use GDataFeedFromString to parse the server response as if it were a GDataFeed.

It should contain the token as a URL parameter. Example: 'http://example.com/?...&token=abcd435' scopes_included_in_next: If True, this function looks for a scope value associated with the token. The scope is a URL parameter with the key set to SCOPE_URL_PARAM_NAME. This parameter should be present if the AuthSub request URL was generated using GenerateAuthSubRequestUrl with include_scope_in_next set to True. Returns: A tuple containing the token string and a list of scope strings for which this token should be valid. If the scope was not included in the URL, the tuple will contain (token, None).` GenerateAuthSubRequestUrl(next, scopes, hd='default', secure=False, session=True, request_url='https://www.google.com/accounts/AuthSubRequest', include_scopes_in_next=True) `Creates a URL to request an AuthSub token to access Google services. For more details on AuthSub, see the documentation here: http://code.google.com/apis/accounts/docs/AuthSub.html Args: next: The URL where the browser should be sent after the user authorizes the application. This page is responsible for receiving the token which is embeded in the URL as a parameter. scopes: The base URL to which access will be granted. Example: 'http://www.google.com/calendar/feeds' will grant access to all URLs in the Google Calendar data API. If you would like a token for multiple scopes, pass in a list of URL strings. hd: The domain to which the user's account belongs. This is set to the domain name if you are using Google Apps. Example: 'example.org' Defaults to 'default' secure: If set to True, all requests should be signed. The default is False. session: If set to True, the token received by the 'next' URL can be upgraded to a multiuse session token. If session is set to False, the token may only be used once and cannot be upgraded. Default is True. request_url: The base of the URL to which the user will be sent to authorize this application to access their data. The default is 'https://www.google.com/accounts/AuthSubRequest'. include_scopes_in_next: Boolean if set to true, the 'next' parameter will be modified to include the requested scope as a URL parameter. The key for the next's scope parameter will be SCOPE_URL_PARAM_NAME. The benefit of including the scope URL as a parameter to the next URL, is that the page which receives the AuthSub token will be able to tell which URLs the token grants access to.
