| |
| The ``run()`` function is called from your application and runs |
| through all the steps to obtain credentials. It takes a ``Flow`` |
| argument and attempts to open an authorization server page in the |
| user's default web browser. The server asks the user to grant your |
| application access to the user's data. If the user grants access, |
| the ``run()`` function returns new credentials. The new credentials |
| are also stored in the ``storage`` argument, which updates the file |
| associated with the ``Storage`` object. |
| |
| It presumes it is run from a command-line application and supports the |
| following flags: |
| |
| ``--auth_host_name`` (string, default: ``localhost``) |
| Host name to use when running a local web server to handle |
| redirects during OAuth authorization. |
| |
| ``--auth_host_port`` (integer, default: ``[8080, 8090]``) |
| Port to use when running a local web server to handle redirects |
| during OAuth authorization. Repeat this option to specify a list |
| of values. |
| |
| ``--[no]auth_local_webserver`` (boolean, default: ``True``) |
| Run a local web server to handle redirects during OAuth authorization. |
| |
| Since it uses flags make sure to initialize the ``gflags`` module before |
| calling ``run()``. |
| |
| Args: |
| flow: Flow, an OAuth 2.0 Flow to step through. |
| storage: Storage, a ``Storage`` to store the credential in. |
| http: An instance of ``httplib2.Http.request`` or something that acts |
| like it. |
| |
| Returns: |
| Credentials, the obtained credential. |
