javascript - AngularJS 服务未定义 : Unknown provider: $scopeProvider <- $scope

Question

我已经开始学习 Angular JS，但在将服务注入(inject) Controller 时遇到了问题。我试图将 ThreadFactory 服务放入 ThreadController 中，但在调用它时遇到未定义的错误。任何建议都会很棒。我得到的错误是:

未知提供者:$scopeProvider <- $scope <- ThreadService

app.js

angular.module('threadsApp', ['ngRoute']);
angular.module('threadsApp')
    .config(function ($routeProvider, $locationProvider) {
        $routeProvider
            .when('/', {
                templateUrl: 'views/index.html',
            })
            .when('/selected/:topicName', {
                templateUrl: 'views/threads.html',
                controller: 'ThreadController',
            })
            .otherwise({
                redirectTo: "/"
            });
            $locationProvider.html5Mode(true);
    });

ThreadController.js

angular.module('threadsApp').controller("ThreadController",
    ["$scope", "$route", "$routeParams", "ThreadService", function ($scope, $route, $routeParams, ThreadService) {
    $scope.test = "Hello!";
    $scope.test2 = ThreadService.get();
}]);

ThreadService.js

angular.module('threadsApp').service("ThreadService", ["$scope", function ($scope) {
    return {
        get: function() {
            return "Hello";
        }
    }
}]);

进口顺序

您实际上无法按照您尝试的方式将 $scope 注入(inject)到您的 ThreadService 中。当您将 $scope 注入(inject) Controller 时，它不是典型的服务。如果您从 Threadservice.js 中删除 $scope 注入(inject)，我敢打赌错误会消失。

为了避免冗余，可以在此处找到更完整的解释:
