这里的ContinueWebAuthentication是在用户接受让应用程序获取配置文件信息后触发的，"code"的值不是想要的，在W8.1应用程序中，"code"的值是正确的，但这里不是。因此，我无法获得用户配置文件信息
我终于想通了。
- 将AuthenticateAndContinue方法的"StartUri"参数中的"redirect_uri"查询参数修改为
http://localhost - 将"AuthenticateAndContinue"方法的CallbackURL(或"EndUri")参数也更改为等于
http://localhost
几个小时后，这是我的工作。我通过浏览代码找到了答案:http://code.msdn.microsoft.com/windowsapps/Authentication-using-bb28840e，特别是在身份验证中查看类"GoogleService.cs"。解决方案的共享项目。
