Angular js-TypeError:无法读取未定义的属性“get”

我有一个平均堆栈应用程序,点击一个按钮,就会调用translate函数。单击按钮后,它将进入此功能,但随后无法执行 http.get 引发错误的部分:

TypeError:无法读取未定义的属性“get”

(function() {
    var app = angular.module('dashboard', []);
    app.config(['$stateProvider', function($stateProvider) {
        $stateProvider.state('secured.dashboard', {
            url: '/dashboard',
            controller: 'searchController',
            templateUrl: '/views/dashboard.html'
        });
    }]);

    app.controller('searchController', ['$scope', 'AuthService', '$state', '$http', function($scope, AuthService, user, $state, $http) {
        console.log($scope.user)
        // AuthService.setUser(user);
        console.log("In search controller");
        $scope.logout = function() {
            AuthService.logout().then(function() {
                $scope.user = null;
                $state.go('unsecured');
            })
        }

        $scope.data = {};

        $scope.translate = function() {
            console.log("Entered")
            console.log($scope.item);
            $scope.show_results = true;

            $http.get('/mosesTranslateSmall', { params: { name: $scope.item }, timeout: 600000 }).
            then(function(response) {
                console.log(response.data);
                $scope.data.moses_less = response.data;

            });

我已经研究了类似的问题,这些问题建议在控制器中将http作为参数传递,但在这样做时,它仍然会抛出一个错误。
