如何在WebView中顯示受保護的Blog（setHttpAuthUsernamePassword）

Question

我想將受保護的Blog顯示爲webview。 博客是對谷歌的blogger.com

用戶名密碼&由應用程序本身（使用戶不必輸入任何東西）提供：

我用下面的代碼，但它不起作用，因爲它要求用戶輸入其用戶名和密碼（僅在第一個日誌中，然後保存並且工作正常）？怎麼了 ？我應該被使用在「境界」：

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

整個代碼至今：

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(); 
    } 
}

     TermsDialog();

public void TermsDialog(){ 

    AlertDialog.Builder ad = new AlertDialog.Builder(this); 
    ad.setIcon(R.drawable.icon); 
    // custom Title - that's the way I found to center it ! 
    TextView title = new TextView(mContext); 
    title.setText(R.string.TermsDialog_Title); 
    title.setBackgroundColor(Color.BLACK); 
    title.setPadding(10, 10, 10,10); 
    title.setGravity(Gravity.CENTER); 
    title.setTextColor(Color.WHITE); 
    title.setTextSize(20); 
    // to center the TITLE : 
    ad.setCustomTitle(title); 

    ad.setView(LayoutInflater.from(this).inflate(R.layout.terms_dialog,null)); 

    ad.setPositiveButton(R.string.TermsDialog_Yes, 
      new android.content.DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int arg1) { 
      //OK, save accepted Terms and Service into the Prefs. 
      terms_agreed = true;

      saving_the_prefs(); 
     } 
    } 
    ); 

    ad.setNegativeButton(R.string.TermsDialog_No, 
      new android.content.DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int arg1) { 
      terms_agreed = false; 
      //tracker.trackPageView("/Terms_NOT_agreed"); 
      saving_the_prefs(); 
      finish(); 
     } 
    } 
    ); 

    ad.setCancelable(false); 

    ad.show(); 
} 

// ================================================================================= 
private void reading_the_prefs() { 

    prefs = getSharedPreferences("Market_Wrap", 0); 
    log_number = prefs.getInt("log_number" , 0); 
    terms_agreed = prefs.getBoolean("terms", false); 
    Log.i("Hub", "log_number="+log_number); 
    Log.i("Hub", "terms_agreed="+terms_agreed); 

} 
// ================================================================================= 
public void saving_the_prefs() { 

    prefs = getSharedPreferences("Market_Wrap", 0); 
    SharedPreferences.Editor editor = prefs.edit(); 

    editor.putInt("log_number", log_number); 
    editor.putBoolean("terms", terms_agreed); 
    editor.commit(); 
} 
// ================================================================================= 

@Override 
protected void onPause() { 
    super.onPause(); 

    //tracker.dispatch(); 
    //tracker.stop(); 
    saving_the_prefs(); 
} 
// ================================================================================= 

}

我試圖照做here但它看起來像

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); 
    } 

永遠不會因爲什麼原因被觸發（在MyWebViewClient中）？

編輯：也許我需要在Android上實現客戶端OAuth？

從setHttpAuthUsernamePassword，您需要在站點的主機通過：所以如果你正在訪問（例如）http://www.google.com從您的代碼和領域Protected用戶名和密碼，你會做

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

您可以通過查看瀏覽器發佈的境界得到的境界：例如，在Firefox中，如果你打開http://tools.dynamicdrive.com/password/example/，你會看到，在標題下面的文字：用戶名和密碼都被0123要求。該網站說：「禁區在這種情況下，境界禁區
