我曾两次尝试通过身份验证访问网站，但我不确定我的尝试有什么问题。我会一一列举。有没有人试过这个并让它工作？

这对于 Java Android 程序员来说应该不难理解，我使用 monodroid EDIT也不重要（这很重要，因为我在下面有一个运行良好的 Java 实现）END EDIT。

我正在尝试通过 WebView 访问 SSRS RDL，我需要插入一些通用凭据。

活动：

    public static string username = "...";
    public static string password = "...";
    public static string website  = "http://10.0.0.5/Reports";

    private WebView webView;

    private void setupWebView(int attempt)
    {
        webView.Settings.JavaScriptEnabled = true;
        webView.Settings.BlockNetworkLoads = false;

        switch (attempt)
        {
            case 1:
                {
                    webView.SetHttpAuthUsernamePassword(website, "", username, password);                                              
                }break;
            case 2:
                {
                    webView.SetWebViewClient(new AuthenticationClient(this));                        
                }break;
        }
        webView.LoadUrl(website);
    }

    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);

        webView = new WebView(this);

        setupWebView(1);//1 or 2 depending on what I am testing

        // Set our view from the "main" layout resource
        SetContentView(webView);           
    }
}

身份验证客户端：

    //DECLARED IN ANOTHER FILE
    [Android.Runtime.Register("android/webkit/WebViewClient", DoNotGenerateAcw = true)]
    public class AuthenticationClient:WebViewClient
    {
        private Context _context;

        public AuthenticationClient(Context context)
        {
            _context = context;
        }

        public override void OnReceivedError(WebView view, ClientError errorCode, string description, string failingUrl)
        {
            Toast.MakeText(_context, "OnReceivedError: " + errorCode, ToastLength.Long);
            //base.OnReceivedError(view, errorCode, description, failingUrl);
        }

        public override void OnPageStarted(WebView view, string url, Android.Graphics.Bitmap favicon)
        {
            Toast.MakeText(_context, "OnPageStarted: " + url, ToastLength.Long);
            //base.OnPageStarted(view, url, favicon);
        }

        public override bool ShouldOverrideUrlLoading(WebView view, string url)
        {
            Toast.MakeText(_context, "ShouldOverrideUrlLoading: " + url, ToastLength.Long);
            view.LoadUrl(url);
            return true;
        }

        public override void OnReceivedHttpAuthRequest(WebView view, HttpAuthHandler handler, string host, string realm)
        {
            Toast.MakeText(_context, "OnReceivedHttpAuthRequest: " + host, ToastLength.Long);
            handler.Proceed(Activity1.username, Activity1.password);
        }
    }
    //END DECLARATION

尝试 1：它甚至不尝试加载页面。我不断收到错误消息：
chromium(18710): external/chromium/net/http/http_auth_gssapi_posix.cc:463: [0821/095922:WARNING:http_auth_gssapi_posix.cc(463)] 无法找到兼容的 GSSAPI 库

尝试 2：不显示单个 toast 消息。

我已经看过： http:

Using WebView setHttpAuthUsernamePassword?
WebView.setHttpAuthUsernamePassword() 不工作？
从 Web 应用程序将用户名和密码传递给 SSRS 2005 报告

其他
东西 我现在已经用 Java 完成了它，它工作正常。我仍然需要一个 Mono for Android 解决方案：

public class Android_reporttestActivity extends Activity {
public static String username = "...";
public static String password = "...";
public static String website = "http://10.0.0.5/Reports";       

private WebView setupWebView()
{
    WebView webView = new WebView(this); 

    webView.setWebViewClient(
        new WebViewClient(){
            public void onReceivedHttpAuthRequest(WebView view, HttpAuthHandler handler, String host, String realm)
            {                           
                handler.proceed(username,password);
            }
        }
    );

    return webView;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    WebView webview = setupWebView();

    // Set our view from the "main" layout resource
    setContentView(webview);

    webview.loadUrl(website);
}

为我运行以下命令可以让一切按预期工作：

[Activity (Label = "WebViewExample", MainLauncher = true)]
public class Activity1 : Activity
{
    string url;
    WebView mWebView;

    protected override void OnCreate (Bundle bundle)
    {
        base.OnCreate (bundle);

        // Set our view from the "main" layout resource
        SetContentView (Resource.Layout.Main);

        url = "http://awebsite.com"; 
        mWebView = (WebView)FindViewById<WebView> (Resource.Id.webview);
        mWebView.SetWebViewClient (new ViewClient (this));
        mWebView.Settings.JavaScriptEnabled = (true);
        mWebView.Settings.PluginsEnabled = (true);
        mWebView.LoadUrl (url);
    }

    class ViewClient : WebViewClient
    {
        Activity1 _activity;

        public ViewClient(Activity1 activity)
        {
            _activity = activity;   
        }

        public override void OnPageStarted (WebView view, string url, Android.Graphics.Bitmap favicon)
        {
            Console.WriteLine ("On Page Started");
        }

        public override void OnReceivedHttpAuthRequest (WebView view, HttpAuthHandler handler, string host, string realm)
        {
            Console.WriteLine ("On received Http auth request");
            handler.Proceed("username", "password");
        }

        public override bool ShouldOverrideUrlLoading (WebView view, string url)
        {
            Console.WriteLine ("Should Override Url Loading...");
            return base.ShouldOverrideUrlLoading (view, url);
        }
    }
}

你的 toast 没有显示的原因可能是因为你没有在它们上调用“.Show()”，所以它们永远不会显示。

如果您仍然无法启动并运行它，那么提供一个我们可以用来攻击的 URL 将非常有用。

我希望这有帮助，
