Question

我使用php后端开发Angularjs应用程序。我得到了这样的错误

Error: [$injector:unpr] http://errors.angularjs.org/1.2.25/$injector/unpr?p0=constantsProvider%20%3C-onstants%20%3C-%20userService

和我的控制器

(function () {
'use strict';
angular.module('smss').controller('loginController', ['$scope','userService','$http', loginController]);

function loginController($scope,userService, $http) {
    $scope.data = {email: '', password: ''};

    // login function 
    $scope.login = function (data) {

        // user auth data 
        var authData = {
            email: data.email,
            password: data.password,
            id: 1
        }

        userService.authUser(authData).success(function(){       
            }).error(function(){
              $scope.data = {email : '',password : ''};
            })

      }

  }

})();

和我的服务类如下

(function() {
    "use strict";
    angular.module('smss').service('userService', ['$http','constants', userService]);

    function userService($http,constants) {
        return {
            checkUser: function(data){
                return $http.post(constants.SERVER_URL+ '/api/checkUser',data);
            },
            newUser: function(data){
                return $http.post(constants.SERVER_URL+ '/api/newUser',data);
            },
            authUser: function(data){  
                $http.post('api/authUser.php', data).success(function (data) {
                        console.log(data);

                });
                return $http.post(constants.SERVER_URL+ '/api/authUser',data); 
            }
        };
    }
})();

和常量

(function() {
     "use strict";
    angular.module('smss').constant('constants', {
        SERVER_URL: 'http://localhost/security/'
    })
})();

为什么，我得到这样的错误？我怎么解决？有 userService ，我想添加我的控制器，但我得到以下错误。

我想发送$ http post requst到我的php文件，但我试着这样做。

你的问题是你没有正确地注入$ http。你忘记添加$ http。

angular.module('smss',[]);// You must need to declare module this way.

比，

angular.module('smss').controller('loginController', ['$scope','userService','$http', loginController]);

 function loginController($scope,userService, $http) {}

angular.min.js：92错误：[$ injector：unpr]
