任何人都知道如何将 google+ 集成到 flex 移动应用程序中。当我尝试使用 google+ 进行身份验证时，收到类似 text="Error #2032: Stream Error. URL: https://accounts.google.com/o/oauth2/auth?response%5Ftype=code&redirect%5Furi=urn%3Aietf之类的错误%3Awg%3Aoauth%3A2%2E0%3Aoob&client%5Fid ..." errorID=2032]。网址：https ://accounts.google.com/o/oauth2/auth 。

该文档是Using OAuth 2.0 for Installed Applications并且您从网页标题中获取访问令牌。
下面是我的视图和我的应用程序和 Google+ API 控制台的屏幕截图：
