Javascript 注入控制器时未定义服务
我有一个控制器,我已将工厂注入其中,但当我调用该工厂上的方法时,它返回为未定义。我不知道我做错了什么。任何帮助都将不胜感激 工厂:Javascript 注入控制器时未定义服务,javascript,angularjs,dependency-injection,angularjs-controller,angularjs-factory,Javascript,Angularjs,Dependency Injection,Angularjs Controller,Angularjs Factory,我有一个控制器,我已将工厂注入其中,但当我调用该工厂上的方法时,它返回为未定义。我不知道我做错了什么。任何帮助都将不胜感激 工厂: (function(){ 'use strict'; // Declare factory and add it 'HomeAutomation' namespace. angular.module('HomeAutomation').factory('AuthenticationService', ['$http','$localStor

callback(res);

}).error(function(err){
console.log(err);

}
function Logout(){
$localStorage.currrntUser
}
function parseJWT(token){
var base64URL, base64;
base64URL = token.split('.')[1];
base64 = base64URL.replace('-', '+').replace('_', '/');
console.log(JSON.parse($window.atob(base64)));
}
function loginStatus(){
if($localStorage.currentUser){
return true;
}else{
return false;
}
}
}]);}());
控制器:
(function(){
angular.module('HomeAutomation')
.controller('loginController', ['$scope', '$location', 'AuthenticationService', function($scope, $location, $localStorage, AuthenticationService){
$scope.isLoggedIn = AuthenticationService.logout();
$scope.logUserIn = function(){
AuthenticationService.login($scope.login.email, $scope.login.password, function(result){
if(result === true){
$location.path('/');
}else{
console.log(result);
}
});
};
$scope.logUserOut = function(){
AuthenticationService.logOut();
}
}]);}());
这是导致错误的行:
$scope.isLoggedIn = AuthenticationService.logout();
显然,“AuthenticationService”没有定义。不知道为什么
提前感谢。您弄乱了依赖顺序,您需要从控制器工厂函数中删除
$localStorage
,因为$localStorage
在控制器中的任何位置都没有使用,也没有注入到DI阵列中
.controller('loginController', ['$scope', '$location', 'AuthenticationService',
function($scope, $location, AuthenticationService){
//^^^^^^^^^^removed $localStorage dependency from here
注意:始终确保在DI数组中注入任何依赖项时,它们应该在控制器函数中以相同的顺序使用
注射不好:
.controller('loginController', ['$scope', '$location', 'AuthenticationService', function($scope, $location, $localStorage, AuthenticationService){
试试这个:
.controller('loginController', ['$scope', '$location', '$localStorage', 'AuthenticationService', function($scope, $location, $localStorage, AuthenticationService){
我不知道您使用哪种生成器,但例如,对于Gulp
,您可以使用Gulp ng annotate
,它将为您完成这项工作,因此您只能编写:
.controller('loginController', function($scope, $location, $localStorage, AuthenticationService){
没有数组。
ng注释将处理其余部分。我确实使用gulp。我会试试看。谢谢
