android - 如何将 protected 博客显示到 WebView 中(setHttpAuthUsernamePassword)

Question

我想在 WebView 中显示 protected 博客。该博客在 Google 的 blogger.com 上

用户名和密码由应用程序本身提供(因此用户无需输入任何内容):

我正在使用以下代码，但它不起作用，因为它要求用户输入其用户名和密码(仅在第一个日志中，然后被保存并且工作正常)？怎么了 ？我应该将什么用作“领域”:

webview.setHttpAuthUsernamePassword(URL_WebView, "", getString(R.string.username), getString(R.string.password));

到目前为止的全部代码:

public class Main extends Activity {
/** Called when the activity is first created. */

String URL_WebView = "http://myblog.blogspot.com/";

public static Context mContext;
static SharedPreferences prefs;

static int log_number;
Boolean terms_agreed;           

//GoogleAnalyticsTracker tracker;
//static String analytics_tracker = "UA-11967031-29";

WebView webview;
private static final FrameLayout.LayoutParams ZOOM_PARAMS = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT, Gravity.BOTTOM);


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

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.main);
    this.webview = (WebView)findViewById(R.id.webkitWebView1);

    mContext = this;

    reading_the_prefs();
    log_number = log_number + 1;

    if (log_number >= 2) {
        if ((!terms_agreed)){
            TermsDialog();
        }
    }

    /*
    tracker = GoogleAnalyticsTracker.getInstance();
    tracker.start(analytics_tracker, this);
    tracker.trackPageView("/Main");
    */

    // adding the zoom controls ...
    FrameLayout mContentView = (FrameLayout) getWindow().getDecorView().findViewById(android.R.id.content);
    final View zoom = this.webview.getZoomControls();
    mContentView.addView(zoom, ZOOM_PARAMS);
    zoom.setVisibility(View.GONE);

    WebSettings settings = webview.getSettings();
    settings.setJavaScriptEnabled(true);
    webview.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);

    webview.setWebViewClient(new MyWebViewClient ());

    //webview.savePassword(URL_WebView, getString(R.string.username), getString(R.string.password));    
    webview.setHttpAuthUsernamePassword(URL_WebView, "", getString(R.string.username), getString(R.string.password));   
    webview.loadUrl(URL_WebView);

}

private class MyWebViewClient extends WebViewClient {

    public void onReceivedHttpAuthRequest(WebView view,
            HttpAuthHandler handler, String host, String realm) {

        handler.proceed(getString(R.string.username), getString(R.string.password));        
        Log.i("Hub","Host ="+host+" with realm ="+realm);
    }

    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        Log.e("Hub", "Error: " + description);
        Toast.makeText(Main.this, "Oh no! " + description, Toast.LENGTH_LONG).show();
    }

我已经尝试听从建议 here但它看起来像

public void onReceivedHttpAuthRequest(WebView view,
            HttpAuthHandler handler, String host, String realm) {

        handler.proceed(getString(R.string.username), getString(R.string.password));        
        Log.i("Hub","Host ="+host+" with realm ="+realm);
    }

无论出于何种原因，永远不会被触发(在 MyWebViewClient 中)？

编辑:也许我需要在 Android 上实现客户端 OAuth？

来自 setHttpAuthUsernamePassword ，您需要传入站点的主机:所以如果您正在访问(例如)http://www.google.com使用您的代码和领域中的用户名和密码 Protected，您可以这样做

webview.setHttpAuthUsernamePassword("www.google.com", "Protected", getString(R.string.username), getString(R.string.password));

您可以通过在浏览器中查看已发布的领域来获取领域:例如，在 Firefox 中，如果您打开 http://tools.dynamicdrive.com/password/example/您会在标题中看到以下文本:http://tools.dynamicdrive.com 正在请求用户名和密码| .该网站说:“限制区域。在这种情况下，领域是限制区域。
