这是我的code.php。
我已经采取了这个代码https://developers.google.com/+/web/signin/server-side-flow。我想添加谷歌+服务器端注册到我的应用程序。所以我决定运行示例代码。我得到的错误，而我已经运行的代码。我已经包含了用于PHP的Google api客户端库。我无法使用代码

我认为问题在于文档为您提供了不完整的代码片段(我已经打开了一个关于此的错误)。这个特定的示例依赖于Symfony，这就是您遇到的丢失的变量/方法。
PHP快速入门提供了完整的说明来设置这个特定的示例。你也可以从Github获得完整的源代码。
你当然不必使用Symfony，但如果你选择使用本地PHP方法，你需要更新对$request， $app和其他样例使用的Symfony方法的引用。

获取用户信息:
查看下面的代码，从Google+ API获取用户信息。
问题是你的应用程序上没有一个$app对象，当你的应用程序试图在会话中设置状态时，可以调用set方法。
也就是说，google端的文档告诉读取文档的用户确保状态值存储在他们的应用程序会话中，以及如何存储google_auth API所需的其他值。
