我正在尝试在我的通用应用程序中添加 Google 登录，对于 Windows 8.1 应用程序，这很容易做到，但对于 Windows Phone 8.1 WinRT 应用程序， 这是我做的代码:

在用户同意让应用程序获取个人资料信息后触发的 ContinueWebAuthentication 中，“代码”的值不是所需的值，在 W8.1 应用程序中，“代码”的值是正确的，但在这里不是. 因此，我无法获取用户个人资料信息
最佳答案
我终于明白了。
- 将 AuthenticateAndContinue 方法的“StartUri”参数中的“redirect_uri”查询参数更改为
http://localhost - 将“AuthenticateAndContinue”方法的 CallbackURL(或“EndUri”)参数更改为也等于
http://localhost
几个小时后，这对我有用。我通过浏览以下代码找到了答案:http://code.msdn.microsoft.com/windowsapps/Authentication-using-bb28840e并专门查看解决方案的 Authentication.Shared 项目中的类“GoogleService.cs”。
希望这对您有所帮助。
