Question

我有一个适用于以前版本的Android操作系统的WebView，但是在加载Ice Cream Sandwich设备时遇到了问题。我正在尝试加载的页面需要BASIC AUTH，并且为了非安全目的而传入查询字符串参数。

问题在于WebViewClient.onReceivedHttpAuthRequest方法：

 String[] up = view.getHttpAuthUsernamePassword(host, realm);

它返回一个null数组而不是用户的id和密码。任何人都知道为什么这在Android ICS中有不同的行为？我获得了其他版本操作系统的用户ID和密码。

完整代码：

public class DestinationWebViewScreen extends Activity{

    WebView mWebView;

    @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            setContentView(R.layout.destination_webview);

            mWebView = (WebView) findViewById(R.id.social_destination_webview);
            mWebView.getSettings().setJavaScriptEnabled(true);
            mWebView.getSettings().setLoadsImagesAutomatically(true);
            mWebView.clearCache(true);
            mWebView.clearFormData();
            mWebView.clearHistory();   
            mWebView.getSettings().setBuiltInZoomControls(true); 

            mWebView.setHttpAuthUsernamePassword("HOST_OF_WEBAPP","Spring Security Application", "USERID", "PASSWORD");

            mWebView.setWebViewClient( new WebViewClient() { 
                @Override 
                public void onReceivedHttpAuthRequest  (WebView view, 
                        HttpAuthHandler handler, String host,String realm){ 

                    String[] up = view.getHttpAuthUsernamePassword(host, realm); 
                    if( up != null && up.length == 2 ) { 
                        handler.proceed(up[0], up[1]); 
                    } 
                }


                @Override
                public void onPageStarted(WebView view, String url, Bitmap favicon) {
                    super.onPageStarted(view, url, favicon);

                    if(progressDialog != null){
                        progressDialog.dismiss();
                    }

                    showProgressbar();
                }


                @Override
                public void onPageFinished(WebView view, String url) {              
                    super.onPageFinished(view, url);

                    dismissProgressDialog();
                }

                @Override
                public void onReceivedError(WebView view, int errorCode,
                        String description, String failingUrl) {                
                    super.onReceivedError(view, errorCode, description, failingUrl);

                    dismissProgressDialog();


                }



            });

    mWebView.loadUrl("https://webapphost/webapp?customerId=0-222293");

    IntentFilter filter = new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION);        
            registerReceiver(networkStateReceiver, filter);
    }

    public void showProgressbar() {
        progressDialog = new CustomProgressDialog(SocialDestinationWebViewScreen.this); 
        progressDialog.getWindow().setBackgroundDrawable(getResources().getDrawable(android.R.color.transparent));
        progressDialog.setMessage(SocialDestinationWebViewScreen.this.getResources().getString(R.string.loading));
        progressDialog.show();
    }


    void dismissProgressDialog(){

        if(progressDialog != null){
            progressDialog.dismiss();
        }

        progressDialog = null;
    }

}

您是否检查了在#onReceivedHttpAuthRequest中收到的内容？

我刚刚修改了你说的话。似乎ICS不仅作为主机返回“主机”，而且还返回端口，例如：HOST_OF_WEBAPP：80。

因此，如果在#onReceivedHttpAuthRequest中收到“HOST_OF_WEBAPP：80”，则不会检索存储为“HOST_OF_WEBAPP”的内容。

试一试！

Android ICS WebViewClient onReceivedHttpAuthRequest不再返回UserId和密码
