雲計算中用於應用程序引擎客戶端的哪個URL？

Question

我在我的應用程序中使用雲計算進行推送通知。我在客戶端身份驗證令牌中遇到問題。我使用以下用於驗證客戶端登錄令牌

public class AppEngineClient { 
    private static final String TAG = "AppEngineClient"; 

    public static final String BASE_URL = " <Don't know which URL to use here>"; 
    public static final String AUTH_URL = BASE_URL + "/_ah/login"; 
    public static final String AUTH_TOKEN_TYPE = "ah"; 

    public final Context mContext; 
    public final String mAccountName; 

    public AppEngineClient(Context context, String accountName) { 
     this.mContext = context; 
     this.mAccountName = accountName; 
    } 

    public HttpResponse makeRequest(String urlPath, List<NameValuePair> params) throws Exception { 
     HttpResponse res = makeRequestNoRetry(urlPath, params, false); 
     if (res.getStatusLine().getStatusCode() == 500) { 
      res = makeRequestNoRetry(urlPath, params, true); 
     } 
     return res; 
    } 

    public HttpResponse makeRequestNoRetry(String urlPath, List<NameValuePair> params, boolean newToken) 
      throws Exception { 

     // Get auth token for account 
     Account account = new Account(mAccountName, "com.google"); 
     String authToken = getAuthToken(mContext, account); 
     if (authToken == null) throw new PendingAuthException(mAccountName); 
     if (newToken) { // invalidate the cached token 
      AccountManager accountManager = AccountManager.get(mContext); 
      accountManager.invalidateAuthToken(account.type, authToken); 
      authToken = getAuthToken(mContext, account); 
     } 

     // Get ACSID cookie 
     DefaultHttpClient client = new DefaultHttpClient(); 
     String continueURL = BASE_URL; 
     URI uri = new URI(AUTH_URL + "?continue=" + 
       URLEncoder.encode(continueURL, "UTF-8") + 
       "&auth=" + authToken); 
     HttpGet method = new HttpGet(uri); 
     final HttpParams getParams = new BasicHttpParams(); 
     HttpClientParams.setRedirecting(getParams, false); // continue is not used 
     method.setParams(getParams); 

     HttpResponse res = client.execute(method); 
     Header[] headers = res.getHeaders("Set-Cookie"); 
     if (res.getStatusLine().getStatusCode() != 302 || 
       headers.length == 0) { 
      return res; 
     } 

     String ascidCookie = null; 
     for (Header header: headers) { 
      if (header.getValue().indexOf("ACSID=") >=0) { 
       // let's parse it 
       String value = header.getValue(); 
       String[] pairs = value.split(";"); 
       ascidCookie = pairs[0]; 
      } 
     } 

     // Make POST request 
     uri = new URI(BASE_URL + urlPath); 
     HttpPost post = new HttpPost(uri); 
     UrlEncodedFormEntity entity = 
      new UrlEncodedFormEntity(params, "UTF-8"); 
     post.setEntity(entity); 
     post.setHeader("Cookie", ascidCookie); 
     post.setHeader("X-Same-Domain", "1"); // XSRF 
     res = client.execute(post); 
     return res; 
    } 

    public String getAuthToken(Context context, Account account) { 
     String authToken = null; 
     AccountManager accountManager = AccountManager.get(context); 
     try { 
      AccountManagerFuture<Bundle> future = 
        accountManager.getAuthToken (account, AUTH_TOKEN_TYPE, false, null, null); 
      Bundle bundle = future.getResult(); 
      authToken = bundle.getString(AccountManager.KEY_AUTHTOKEN); 
      // User will be asked for "App Engine" permission. 
      if (authToken == null) { 
       // No auth token - will need to ask permission from user. 
       Intent intent = new Intent("com.google.ctp.AUTH_PERMISSION"); 
       intent.putExtra("AccountManagerBundle", bundle); 
       context.sendBroadcast(intent); 
      } 
     } catch (OperationCanceledException e) { 
      Log.w(TAG, e.getMessage()); 
     } catch (AuthenticatorException e) { 
      Log.w(TAG, e.getMessage()); 
     } catch (IOException e) { 
      Log.w(TAG, e.getMessage()); 
     } 
     return authToken; 
    } 

    public class PendingAuthException extends Exception { 
     private static final long serialVersionUID = 1L; 
     public PendingAuthException(String message) { 
      super(message); 
     } 
    } 
} 

這是我通過瀏覽器使用用戶認證通過應用程序引擎的客戶打電話例如雲計算的類，但在使用這個類，我不明白這BASE_URL，我必須在這堂課中給予。請告訴我，如果URL來自服務器端，應使用哪個URL以及在服務器端要做什麼。

在此先感謝

應用服務引擎基本URL模式或者是

http://<<appname>>.appspot.com或https://<<appname>>.appspot.com
