Client class

An OAuth2 client.

This acts as a drop-in replacement for an http.Client, while sending OAuth2 authorization credentials along with each request.

The client also automatically refreshes its credentials if possible. When it makes a request, if its credentials are expired, it will first refresh them. This means that any request may throw an AuthorizationException if the refresh is not authorized for some reason, a FormatException if the authorization server provides ill-formatted responses, or an ExpirationException if the credentials are expired and can't be refreshed.

The client will also throw an AuthorizationException if the resource server returns a 401 response with a WWW-Authenticate header indicating that the current credentials are invalid.

If you already have a set of Credentials, you can construct a Client directly. However, in order to first obtain the credentials, you must authorize. At the time of writing, the only authorization method this library supports is AuthorizationCodeGrant.
