我正在開發一個使用IIFE的項目,這個概念我仍然開始掌握。我的服務似乎要被罰款,我使用了一些茉莉花,以確定它被定義,但是當我嘗試把它注入到我的控制器我得到這個錯誤:當向控制器注入服務時角獲得未知的提供者錯誤
Unknown provider: StudentsServiceProvider <- StudentsService <- StudentsController
這裏是有問題的控制器:
(function() {
'use strict';
angular
.module('ngInterview.students')
.controller('StudentsController', StudentsController);
StudentsController.$inject = ['StudentsService'];
function StudentsController(StudentsService) {
/**
* Model
*/
var vm = this;
/**
* Initialization
*/
activate();
/**
* Implementations
*/
function activate() {
// Initialization code goes here
vm.students = StudentsService.getStudents();
}
}
})();
這裏是服務,以防萬一我搞砸了有莫名其妙:
(function() {
'use strict';
angular
.module('ngInterview.api.students')
.service('StudentsService', StudentsService);
StudentsService.$inject = ['$http'];
function StudentsService($http) {
/**
* Exposed functions
*/
this.getName = getName; // This function serves no purpose. It's just here as an example.
this.getStudents = function() {
return $http({
url: "CUSTOM_URL_HERE",
method: "GET"
}).then(function successCallback(res) {
return res;
}, function errorCallback(res) {
return this.getStudents();
});
}
/**
* Implementations
*/
function getName() {
return 'studentsService';
}
}
})();
上面列出的所有文件都包含在index.html的。如果我取出對StudentsService的引用,則不會收到任何錯誤,並且所有文件都會正確實例化。
