(AngularJS) 无法将工厂注入控制器

(AngularJS) Can't inject factory into controller

我正在尝试将我的工厂注入控制器。如果我将工厂列为控制器的参数之一,我会收到此错误:

Error: [$injector:unpr] Unknown provider: wordRushFacProvider <- wordRushFac <- wordrushCtrl
http://errors.angularjs.org/1.6.1/$injector/unpr?p0=wordRushFacProvider%20%3C-%20wordRushFac%20%3C-%20wordrushCtrl

这是我工厂的代码:

(function() {
    "use strict";

    angular
    .module("wordrush")
    .factory("wordRushFac", function($http) {

        function getValidWords() {
            return $http.get('../data/valid-words.txt');
        }

        return {
            getValidWords : getValidWords
        }
    })
})

我的控制器代码:

(function() {
    'use strict'

    angular
    .module('wordrush')
    .controller('wordrushCtrl', function($scope, $http, wordRushFac) {

        wordRushFac.getValidWords().then(function(words) {
            $scope.words = words.data;
        });
        $scope.words = 'Hello'
    });
})();

我的 index.html:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title>Word Rush</title>

        <link rel="stylesheet" href="node_modules/angular-material/angular-material.css">
        <link rel="stylesheet" type="text/css" href="css/style.css">

        <script src="node_modules/angular/angular.js"></script>
        <script src="scripts/app.js"></script>
        <script src="components/wordrush.ctr.js"></script>
        <script src="components/wordrush.fac.js"></script>
    </head>
    <body ng-app="wordrush" ng-controller="wordrushCtrl">
        <h1> {{ words }} </h1>
    </body>
</html>

我的 app.js:

angular
.module('wordrush', ['ngMaterial'])
.config(function($mdThemingProvider) {

    $mdThemingProvider.theme('default')
    .primaryPalette('blue')
    .accentPalette('green');
})

我用与此相同的代码编写了一个程序,只是更改了名称和变量,并且运行良好。那么我在这里做错了什么?

您没有在控制器中注入,应该是:

.controller('wordrushCtrl', ['$scope', '$http', 'wordRushFac', function($scope, $http, wordRushFac) {
  // Rest of controller code;
}]);

切换脚本。工厂脚本应该首先是控制器

顺序应该是,

<script src="scripts/app.js"></script>
<script src="components/wordrush.fac.js"></script>
<script src="components/wordrush.ctr.js"></script>

DEMO

这是一个 plunkr,上面写着 "Hello":https://plnkr.co/edit/MyxcXQ8YI4QYqeFsyVJz?p=preview

您的控制器定义中有一组额外的开/关括号,请删除它们:

angular
.module('wordrush')
.controller('wordrushCtrl', function($scope, $http, wordRushFac) {

    wordRushFac.getValidWords().then(function(words) {
        $scope.words = words.data;
    });
    $scope.words = 'Hello'
});

此外,您确定包含 ng-material JS 文件吗?我没有在你的 HTML.

中看到它

我进行了以下更改并且效果很好。

(function() {
        "use strict";

        angular
        .module("wordrush")
        .factory("wordRushFac", function($http) {

            function getValidWords() {
                return $http.get('../data/valid-words.txt');
            };

            return {
                getValidWords : getValidWords
            };
        });
    }());
