我有以下组件,我正在尝试注入服务:
angular.
module('phoneList').
component('phoneList', {
templateUrl: '/static/common/angular/phone-list/phone-list.template.html',
controller: ['$http', 'authenticationService',
function PhoneListController($http, authenticationService) {
var self = this;
authenticationService.authenticate().then(function(){
console.log('it worked!!!!!!!!');
});
}
]
});
服务如下:
angular.module('authentication').factory('authenticationService', function($http, $se){
function authenticate(){
$http.post('/o/token/', data, config)
.success(function (data, status, headers, config) {
console.log('auth service: '+data['access_token']);
$sessionStorage.access_token = data['access_token'];
});
}
function getToken(){
return $sessionStorage.access_token;
}
return {
authenticate:authenticate,
getToken:getToken
};
});
我的phone-list.module.js如下所示:
angular.module('phonecatApp', [
'phoneList',
'authentication',
]);
angular.module('phoneList', ['authentication']);
当我运行时,我得到错误:
未捕获的ReferenceError:未定义authenticationService
当我提出' authenticationService'在'',我收到错误:
错误[$ injector:unpr] authtenticationService
答案 0 :(得分:1)
似乎服务没有正确地注入PhoneListController。
将其更改为:
controller: ['$http', 'authenticationService',
function PhoneListController($http, authenticationService) {
...
数组中的字符串只是为了保持注入的依赖引用缩小安全。该服务仍然需要添加为函数参数。
还要确保为每个组件调用angular.module
一次:
app.module.js
angular.module('phonecatApp', [
'ngRoute',
'phoneList',
'authentication',
]);
电话list.module.js
angular.module('phoneList', ['authentication']);
