Cordova身份驗證

Question

我有這個錯誤爲什麼要登錄到我的科爾多瓦/ Ionic應用程序。

Cannot read property 'error_description' of undefined 
TypeError: Cannot read property 'error_description' of undefined

我需要知道，做我的登錄名/密碼是錯誤的，或者只是我的應用程序不能正常工作

認證相關的代碼是

  doLogin:   function (username, password) { 
return ServerAPI.logIn({}, {Username: username, Password: password, Version: AppConstants.Build, grant_type: "password"}).$promise 
     .then(function (response) { 
     if (!response.error) { 
      authService.loginCancelled({}); 
      currentUser.isAuthenticated = !response.error; 
      currentUser.data = response; 
      currentUser.data.UserId = response.currentUserId; 
      currentUser.data.UserName = username; 
      currentUser.UserId = response.currentUserId; 
      currentUser.lastloggedinTimestamp = (new Date()).getTime(); 
      // Saves session data into database so it can be accessed after app reopened 
      Database.insertInto('Session', currentUser.UserId, currentUser, {}); 
      // Saves the session data into a cookie so the request interceptor can access it 
      Session.put('emInspectionUser', currentUser); 
      authService.loginConfirmed(currentUser); 
     } 
     else { 
      Session.remove('emInspectionUser'); 
     } 
     return response; 
     }, function (error) { 
     if (error.status === 0) { 
      return $q.reject('Could not connect to server.\nPlease check your network connection.'); 
     } 
     else if (error.data.error_description) { 
      return $q.reject(error.data.error_description); 
     } 
     return $q.reject(error.status + ': ' + error.statusText); 
     }); 

我正在科爾多瓦應用程序和我已登錄並通過，但我不確定我的登錄和傳球是否正確，並且由於此錯誤，我無法測試。

你可以寫你否則，如果條件如下

else if (error.data.hasOwnProperty(error_description)) { 
    return $q.reject(error.data.error_description); 
}
