javascript - Angular JS 错误 : [$injector:unpr] Unknown provider

Question

我是 Angular js 的新手，我正在尝试制作自定义服务，我已经复制并粘贴了一段代码来制作自定义服务，但我总是收到此错误，

Error: [$injector:unpr] Unknown provider: serviceProvider <- service <-         MainController
http://errors.angularjs.org/1.4.3/$injector/unpr?p0=serviceProvider%20%3C-  %20service%20%3C-%20MainController

at nodeLinkFn (angular.js:8109)
at compositeLinkFn (angular.js:7541)
at publicLinkFn (angular.js:7416)(anonymous function) @ angular.js:12330

这是我的自定义服务实现

(function () {
    var myModule = angular.module('app', ['onsen']);
    myModule.service('service', ["$http", function ($http) {
        var test = function (usertoken) {
            alert("fffffffffffffffffffff");

        }
        return {
            getUserSites: getUserSites
        };
    }]);
})();

这是我的模块实现:

(function () {
    var myApp = angular.module('app', ['onsen']);

    var MainController = function ($scope, $http, $interval, service) {
        $scope.clciclme = function () {
            alert("HIIIIIIIIIIIIIIIIIIII");
        }
    }
    myApp.controller('MainController', MainController);
})();

请帮忙，是什么导致了这个错误？

Answer 1

你使用了模块setter语法两次，即:

var myApp = angular.module('app', ['onsen']);

您正在创建 app 模块两次。要使用 getter 语法，只需不传递第二个参数(数组)即可:

var myApp = angular.module('app');

您的代码如下所示:

Controller :

(function () {
    var myApp = angular.module('app', ['onsen']); // use the setter syntax one time

    var MainController = function ($scope, $http, $interval, service) {
        $scope.clciclme = function () {
            alert("HIIIIIIIIIIIIIIIIIIII");
        }
    }
    myApp.controller('MainController', MainController);
})();

服务:

(function () {
    var myModule = angular.module('app'); // use the getter syntax all subsequent times

    myModule.service('service', ["$http", function ($http) {
        var test = function (usertoken) {
            alert("fffffffffffffffffffff");

        }
        return {
            getUserSites: getUserSites
        };
    }]);
})();
