问题描述
我很难传递此错误：
当我尝试使用AngularJS制作身份验证应用程序。我把代码放在 plunker 中。
when I am trying to make an authentication app with AngularJS. I put the code in plunker.
以下是我的代码：
1- app.js
1- app.js
"use strict";
(function() {
var app = angular.module('loginApp', ['AuthService', 'Session']);
app.constant('appSettings', {
title:'Authentication Application',
version:'1.0'
});
app.constant('AUTH_EVENTS', {
loginSuccess: 'auth-login-success',
loginFailed: 'auth-login-failed',
logoutSuccess: 'auth-logout-success',
sessionTimeout: 'auth-session-timeout',
notAuthenticated: 'auth-not-authenticated',
notAuthorized: 'auth-not-authorized'
});
app.constant('USER_ROLES', {
all: '*',
admin: 'admin',
editor: 'editor',
guest: 'guest'
});
app.controller('footerController', function($scope, appSettings){
$scope.appSettings = appSettings;
});
}());
2 - applicationcontroller.js
2 - applicationcontroller.js
"use strict";
(function() {
var applicationcontroller = function ($scope, USER_ROLES, AuthService) {
$scope.currentUser = null;
$scope.userRoles = USER_ROLES;
$scope.isAuthorized = AuthService.isAuthorized;
$scope.setCurrentUser = function (user) {
$scope.currentUser = user;
};
};
applicationcontroller.$inject = ['$scope', 'USER_ROLES', 'AuthService'];
angular.module('loginApp')
.controller('applicationcontroller', applicationcontroller);
}());
3- logincontroller.js
3- logincontroller.js
"use strict";
(function() {
var logincontroller = function ($scope, $rootScope, AUTH_EVENTS, AuthService) {
$scope.credentials = {
username: '',
password: ''
};
$scope.login = function(credentials){
AuthService.login(credentials).then(function(user){
$rootScope.$broadcast(AUTH_EVENTS.loginSuccess);
$scope.setCurrentUser(user);
}, function(error){
$rootScope.$broadcast(AUTH_EVENTS.loginFailed);
});
};
};
logincontroller.$inject = ['$scope', '$rootScope', 'AUTH_EVENTS', 'AuthService'];
angular.module('loginApp')
.controller('logincontroller', logincontroller);
}());
4- authservice.js
4- authservice.js
"use strict";
(function(){
var AuthService = function($http, Session){
var authService = {};
authService.login = function (credentials) {
return $http
.post('/login', credentials)
.then(function (res) {
Session.create(res.data.id, res.data.user.id,
res.data.user.role);
return res.data.user;
});
};
authService.isAuthenticated = function () {
return !!Session.userId;
};
authService.isAuthorized = function (authorizedRoles) {
if (!angular.isArray(authorizedRoles)) {
authorizedRoles = [authorizedRoles];
}
return (authService.isAuthenticated() &&
authorizedRoles.indexOf(Session.userRole) !== -1);
};
return authService;
};
AuthService.$inject = ['$http', 'Session'];
angular.module('loginApp').factory('AuthService', AuthService);
}());
5- session.js
5- session.js
"use strict";
(function(){
var Session = function(){
this.create = function (sessionId, userId, userRole) {
this.id = sessionId;
this.userId = userId;
this.userRole = userRole;
};
this.destroy = function () {
this.id = null;
this.userId = null;
this.userRole = null;
};
};
angular.module('loginApp').service('Session', Session);
}());

推荐答案
首先，在引用脚本时，您会输入拼写错误文件
First of all you have a typo when referencing your script files
<script arc="js/services/authservice.js"></script>
<script arc="js/services/session.js"></script>
应该是
<script src="js/services/authservice.js"></script>
<script src="js/services/session.js"></script>
第二 - >您的AuthService和Session不是新模块，它们在同一个loginApp模块中注册根据您的代码。因此，您不要将它们注入loginApp模块。
Second -> Your AuthService and Session are not new modules, they are being registered in the same loginApp module based on your code. So you don't inject them into your loginApp module.
更改
var app = angular.module('loginApp', ['AuthService', 'Session']);
到此
var app = angular.module('loginApp', []);
第三 - >在加载app.js之前加载服务脚本文件，记住app.js是您首先定义用于分配服务的loginApp模块的位置，因此将脚本加载顺序更改为此
Third -> You are loading your service script files before loading your app.js, remember app.js is where you are first defining your loginApp module that you are using to assign your services, so change your script load order to be this
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="bootstrap.min.js"></script>
<script src="angular.min.js"></script>
<script src="app.js"></script>
<script src="session.js"></script>
<script src="authservice.js"></script>
<script src="applicationcontroller.js"></script>
<script src="logincontroller.js"></script>
