Google登录返回当前用户为空 [英] Google SignIn returns Current user as null

问题描述

我正在为Xamarin iOS应用程序使用google登录名，但是在出现的safari浏览器提示中成功输入用户名和密码后，它将返回CurrentCurrent属性为null.

I am using google login for my Xamarin iOS app, however after successfully entering the username and password in the safari browser prompt that appears, It returns properties CurrentUser as null.

我的代码:

Google.SignIn.SignIn.SharedInstance.Delegate = this; 
Google.SignIn.SignIn.SharedInstance.UIDelegate = this; 
Google.SignIn.SignIn.SharedInstance.SignInUser(); 
Google.SignIn.SignIn.SharedInstance.SignedIn += SharedInstance_SignedIn;

private void SharedInstance_SignedIn(object sender, SignInDelegateEventArgs e) 
{ 
var signin = (Google.SignIn.SignIn)sender; 
   //Here if i debug signin variable, its property CurrentUser comes as null
}

我正在使用 Xamarin.IOS.Google.Signin:v4.0.1.1

I am using Xamarin.IOS.Google.Signin: v4.0.1.1

我是否缺少一些需要在Google api控制台中启用的设置?

Am I missing some setting that needs to be enabled in the Google api console?

推荐答案

Sender指示引发事件的类.

要获取用户，您可以使用e.User或Google.SignIn.SignIn.SharedInstance.CurrentUser

To get User ,you can use e.User Or Google.SignIn.SignIn.SharedInstance.CurrentUser

此处说明方法SignIn

Sign-In SDK自动获取访问令牌，但是仅当您调用SignIn或SignInSilently方法时，访问令牌才会刷新.

The Sign-In SDK automatically acquires access tokens, but the access tokens will be refreshed only when you call SignIn or SignInSilently methods.
