AngularJS服务未定义：未知提供商：$ scopeProvider＆LT; - $范围 [英] AngularJS Service Undefined: Unknown provider: $scopeProvider <- $scope

问题描述

我已经开始学习角JS和我在与注射服务为一体的控制器出现问题。我试图把的ThreadFactory 服务为 ThreadController ，但调用它时我发现了一个未定义的错误。任何意见将是巨大的。我得到的错误是：

未知提供商：$ scopeProvider＆LT; - $范围＆LT; - ThreadService

app.js

  angular.module（'threadsApp'，['ngRoute']）;
angular.module（'threadsApp'）
    的.config（函数（$ routeProvider，$ locationProvider）{
        $ routeProvider
            。什么时候（'/'， {
                templateUrl：意见/ index.html的，
            }）
            。当（'/选择/：topicName'，{
                templateUrl：意见/ threads.html'，
                控制器：'ThreadController'，
            }）
            。除此以外（{
                redirectTo：/
            }）;
            $ locationProvider.html5Mode（真）;
    }）;
 

ThreadController.js

  angular.module（'threadsApp'）。控制器（ThreadController
    [$范围，$路线，$ routeParams，ThreadService功能（$范围，$路径，$ routeParams，ThreadService）{
    $ scope.test =你好！;
    $ scope.test2 = ThreadService.get（）;
}]）;
 

ThreadService.js

  angular.module（'threadsApp'）。服务（ThreadService，[$范围功能（$范围）{
    返回{
        得到：函数（）{
            返回你好;
        }
    }
}]）;

解决方案

您不能真正注入 $范围到 ThreadService 你想要的方式。 $范围不是一个典型的服务，当你把它注射到控制器。如果从删除 $范围注射的 Threadservice.js 的，我敢打赌错误会消失。

在不是冗余的利益，更全面的解释可以在这里找到：

I've started learning Angular JS and I'm having a problem with injecting a service into a controller. I'm trying to put the ThreadFactory service into ThreadController, but I'm getting an undefined error when calling it. Any advice would be great. The error I'm getting is:

Unknown provider: $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";
        }
    }
}]);

解决方案

You can't actually inject $scope into your ThreadService the way you're trying to. $scope isn't a typical service when you inject it into a controller. If you remove the $scope injection from Threadservice.js, I would bet the error will go away.

In the interest of not being redundant, a fuller explanation can be found here:

Injecting $scope into an angular service function()
