Question

我正在Xamarin.Forms中编写一个简单的应用程序，允许用户通过社交网站进行身份验证，例如Facebook，Google，Instagram，Twitter等。我使用Xamarin.auth来执行此操作。 Facebook登录时遇到问题。我使用了官方指南中报告的相同代码：

https://components.xamarin.com/gettingstarted/xamarin.auth

但是在应用程序请求用户提供凭据后，响应（在代码中，t.Result.GetResponseText（），第3节）是一个json包含Facebook用户名和姓氏，以及一个名为＆＃34的字段; ID＆＃34 ;.相反，我需要用户的所有个人资料信息，例如年龄，性别等。我想我必须使用返回的id来构建对facebook服务的http请求以从id中检索数据。

Answer 1

您需要在Facebook链接中指定所需的字段。
