"""A client utilizing the authorization code grant workflow.

A web application is a confidential client running on a web
    server.  Resource owners access the client via an HTML user
    interface rendered in a user-agent on the device used by the
    resource owner.  The client credentials as well as any access
    token issued to the client are stored on the web server and are
    not exposed to or accessible by the resource owner.

The authorization code grant type is used to obtain both access
    tokens and refresh tokens and is optimized for confidential clients.
    As a redirection-based flow, the client must be capable of
    interacting with the resource owner's user-agent (typically a web
    browser) and capable of receiving incoming requests (via redirection)
    from the authorization server.

The client constructs the request URI by adding the following
        parameters to the query component of the authorization endpoint URI
        using the "application/x-www-form-urlencoded" format, per `Appendix B`_:

:param redirect_uri:  OPTIONAL. The redirect URI must be an absolute URI
                              and it should have been registerd with the OAuth
                              provider prior to use. As described in `Section 3.1.2`_.

:param scope:  OPTIONAL. The scope of the access request as described by
                       Section 3.3`_. These may be any string but are commonly
                       URIs or various categories such as ``videos`` or ``documents``.

:param state:   RECOMMENDED.  An opaque value used by the client to maintain
                        state between the request and callback.  The authorization
                        server includes this value when redirecting the user-agent back
                        to the client.  The parameter SHOULD be used for preventing
                        cross-site request forgery as described in `Section 10.12`_.

:param kwargs:  Extra arguments to include in the request URI.

In addition to supplied parameters, OAuthLib will append the ``client_id``
        that was provided in the constructor as well as the mandatory ``response_type``
        argument, set to ``code``::

                                authorization request as described in `Section 4.1.1`_, and their

In addition OAuthLib will add the ``grant_type`` parameter set to

If the client type is confidential or the client was issued client
        credentials (or assigned other authentication requirements), the

If the resource owner grants the access request, the authorization
        server issues an authorization code and delivers it to the client by
        adding the following parameters to the query component of the
        redirection URI using the "application/x-www-form-urlencoded" format:

:param uri: The callback URI that resulted from the user being redirected
                    back from the provider to you, the client.
        :param state: The state provided in the authorization request.

**code**
            The authorization code generated by the authorization server.
            The authorization code MUST expire shortly after it is issued
            to mitigate the risk of leaks. A maximum authorization code
            lifetime of 10 minutes is RECOMMENDED. The client MUST NOT
            use the authorization code more than once. If an authorization
            code is used more than once, the authorization server MUST deny
            the request and SHOULD revoke (when possible) all tokens
            previously issued based on that authorization code.
            The authorization code is bound to the client identifier and
            redirection URI.

**state**
                If the "state" parameter was present in the authorization request.

This method is mainly intended to enforce strict state checking with
        the added benefit of easily extracting parameters from the URI::
