无法读取未定义的propery getRiders

我想调用我在DeliverService中定义的服务，但是当我从控制器调用它时，出现Cannot read propery getRiders of undefined错误，不知道为什么会发生这种情况：无法读取未定义的propery getRiders

DeliverService.js

angular.module('Deliver') 
    .service('DeliverService', ['$http', '$state', '$resource', '$q', 'SettingService', '$localStorage', "MessageService", function($http, $state, $resource, $q, SettingService, $localStorage, MessageService) { 
     var service = { 
      getRiders : function(){ 
       return $http.get("Hero.json"); 
       //return $http.get(SettingService.baseUrl + "api/orders"); 
      } } 
     return service; 
    }]);

DeliverCtrl.js

use strict'; 
angular.module('Deliver').controller('DeliverCtrl',['$scope','$state', "SettingService","DeliverService", function($scope, $state, $ionicModal, MessageService, SettingService,DeliverService) { 
    $scope.riders = []; 
    DeliverService.getRiders().then(function(response){ 
    $scope.riders = response.data.data; 
    }, function(error){ 
    }); 
}]);

你的依赖是不是在这里的优先顺序。因此，DeliverService实际上并未注入。

控制器代码应该是这个样子：

angular.module('Deliver').controller('DeliverCtrl', 
    ['$scope','$state', '$ionicModal', 'MessageService', 'SettingService','DeliverService', 
    function($scope, $state, $ionicModal, MessageService, SettingService, DeliverService) { 
    $scope.riders = []; 
    DeliverService.getRiders().then(function(response){ 
     $scope.riders = response.data.data; 
    }, function(error){}); 
}]);

是：'D It now now –

Thankyou so much you save m y天 –

@mariasalahuddin很高兴帮助！ :) 一旦定时器关闭，你可以接受答案，以便它可以帮助其他人 – tanmay

在DeliverCtrl.js

注射参数和功能参数不匹配

它应该是这样的

['$scope','$state','$ionicModal','MessageService','SettingService','DeliverService', function($scope, $state, $ionicModal, MessageService, SettingService,DeliverService)
