AngularJs用每個請求檢查用戶

我試圖用每個請求來標識用戶。現在這是我的routes文件：AngularJs用每個請求檢查用戶

(function() { 

angular.module('employeeApp').config(routeModule).run(run); 

routeModule.$inject = ['$routeProvider']; 

function routeModule($routeProvider) 
{ 
    $routeProvider.when('/', { 
     templateUrl: '../views/login.html', 
     controller: 'authenticationController', 
     controllerAs: 'authenticationCtrl' 
    }) 
    .when('/home', { 
     templateUrl: '../views/index.html', 
     controller: 'homeController', 
     controllerAs: 'homeCtrl', 
     resolve: { 
      message: function(authenticationFactory){ 
       return authenticationFactory.validateUser(); 
      } 
     } 
    }) 
    .when('/werknemer/:id', { 
     templateUrl: '../views/employee/employee.html', 
     controller: 'employeeController', 
     controllerAs: 'employeeCtrl' 
    }) 
    .otherwise({ 
     redirectTo: '/' 
    }); 
} 


function run(authenticationFactory) 
{ 
    authenticationFactory.validateUser() 
    .then(function (response) { 
     console.log('validateuser'); 
     constants.firstname = response.data.result.Employee.FirstName; 
     constants.companyid = response.data.result.Employee.CompanyId; 
     constants.employeeid = response.data.result.Employee.EmployeeId; 

    }, function() { 
     $location.path('/'); 
}); 
} 

})();

的function run使用看起來像這樣的authenticationFactory：

(function() 
{ 
    angular.module('employeeApp').factory('authenticationFactory', authenticationFactory); 

    function authenticationFactory($cookieStore,$cookies,requestFactory,$location,GLOBALS,constants) 
    { 
     var factory = {}; 



     factory.validateUser = function() 
     { 
      var vm = this; 

      if($location.path() != '/') 
      { 
       var api_token = factory.getToken(); 

       factory.isValidToken(api_token).then(function(response) { 
        if (response.status != 200) { 
         $location.path('/'); 
        } 
        data = {"api_token": api_token}; 
        requestFactory.post(GLOBALS.url + 'show/employee/' + $cookies.get('employeeid'), data) 
       }); 
      } 
     } 

     return factory; 
    } 
})()

但是現在我收到我的控制檯錯誤：

routes.js:38 Uncaught TypeError: Cannot read property 'then' of undefined

我在做什麼錯？

- 編輯 -

factory.validateUser = function() 
     { 
      var vm = this; 

      if($location.path() != '/') 
      { 
       var api_token = factory.getToken(); 

       factory.isValidToken(api_token).then(function(response) { 
        if (response.status != 200) { 
         $location.path('/'); 
        } 
        data = {"api_token": api_token}; 
        return requestFactory.post(GLOBALS.url + 'show/employee/' + $cookies.get('employeeid'), data) 
       }); 
      } 
     }

'factory.validateUser'不返回請求承諾 –

即使我這樣做，我收到相同的錯誤！看我的編輯。 – Jamie

請參考關於[$ q]的文檔（https://docs.angularjs.org/api/ng/service/$q）你需要這個返回一個probise（來自'factory.validateUser'）你解決/驗證過程後手動拒絕 –

你的ValidateUser函數返回咱這if語句失敗，決心機制總是希望返回的承諾。

嘗試if語句之後添加該自動分辨承諾，作爲一個其他：

var q = $q.defer(); 
q.resolve(); 
return q.promise;

不要忘記注入$ Q（AngularJS的承諾實現）到服務。
