Question

你好我正在使用angular进行我的小项目，在创建我的第二个控制器与第二个服务期间我有一个问题，当我注入我自己的服务作为控制器中的依赖它它不工作和html中的所有表达式文件未解析（在添加服务之前所有工作）这里是我的代码

将AccSrv添加到AccCtrl后出现问题

angular.module('myApp', ['ngRoute', 'membersService']).config(
    ['$httpProvider', '$routeProvider', function ($httpProvider, $routeProvider) {
        $routeProvider.when('/home', {
            templateUrl: 'partials/home.html',
            controller: 'MembersCtrl'
        }).when('/account', {
            templateUrl: 'partials/account.html',
            controller: 'AccCtrl'
        }).otherwise({
            redirectTo: '/home'
        });
    }]);

Answer 1

问题是您的服务是在未包含在任何地方的模块中定义的：

angular.module('AccountService', []).service('AccSrv'...etc

应该是

myApp.service('AccSrv'...etc

否则，您需要将AccountService MODULE包含为myApp的依赖项。

Answer 2

@yBrodsky是正确的，你需要改变

angular.module('AccountService', []).service('AccSrv', ['$http', function ($http) {

要：

angular.module('myApp').service('AccSrv', ['$http', function ($http) {

将服务添加为依赖项后，AngularJS控制器不起作用
