更新：链接已经被日由谷歌pcated $ P $。请参考以下链接上使用谷歌自己的的OAuth2 API文档，而不是困扰了这么多为读书库因为他们是非常复杂，最终可能会失去焦点。
Update: The links have been deprecated by Google. Refer to the following links to use Google's own OAuth2 API documentation instead of bothering so much into reading the libraries because they are very complicated and may end up losing focus.
