我已经尝试过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。我会列出每一个。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,我使用的是 monodroid EDIT 也不重要(这很重要,因为我下面有一个 Java 实现可以正常工作)< em>结束编辑。
我正在尝试通过 WebView 访问 SSRS RDL,我需要插入一些通用凭据。
Activity :
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。
我已经看过了:

其他内容
我现在已经用 Java 完成了它并且工作正常。我仍然需要一个适用于 Android 的 Mono 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);
}
最佳答案
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 toasts 没有显示的原因可能是因为你没有对它们调用“.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命中的 URL 将非常有用。
希望对你有帮助
