ios - Xamarin iOS : Pass credentials over http

Question

我正尝试在我的 xamarin iOS 项目上通过 http 传递凭据，但它不起作用。

public partial class WebView : UIViewController
{

        protected override void ViewDidLoad()
        {
         webView.LoadRequest(new NSUrlRequest(new NSUrl("https:example.com")));
         webView.AllowsBackForwardNavigationGestures = true;
         webView.NavigationDelegate = new WebViewDelegate(this);
        }
}

public class WebViewDelegate : WKNavigationDelegate, INSUrlConnectionDataDelegate
    {

        public override void DidReceiveAuthenticationChallenge(WKWebView webView, NSUrlAuthenticationChallenge challenge, Action<NSUrlSessionAuthChallengeDisposition, NSUrlCredential> completionHandler)
        {
            //base.DidReceiveAuthenticationChallenge(webView, challenge, completionHandler);
            completionHandler(NSUrlSessionAuthChallengeDisposition.PerformDefaultHandling, new NSUrlCredential("username", "password", NSUrlCredentialPersistence.ForSession));
            Console.WriteLine("We are authenticated");
            return;
        }
}

谁能建议如何解决这个问题？

更新:

DidReceiveAuthenticationChallenge 正在被调用，并且在循环中不断被调用。我没有得到预期的页面，而是得到一个空白页面，上面只写着“验证”

来自 Apple 的文档 PerformDefaultHandling :

Use the default handling for the challenge as though this delegate method were not implemented. The provided credential parameter is ignored.

请尝试使用 UseCredential:

var crendential = new NSUrlCredential("user", "pass", NSUrlCredentialPersistence.ForSession);

completionHandler(NSUrlSessionAuthChallengeDisposition.UseCredential, crendential);
