我有一个应用程序
/// <reference path="../Scripts/angular.d.ts" />
/// <reference path="testCtrl.ts" />
/// <reference path="testSvc.ts" />
angular.module('testApp', []);
angular.module('testApp').constant('url','http://whatever');
angular.module('testApp').factory(
'testSvc', ['$http', 'url', testApp.testSvc]);
angular.module('testApp').controller(
'testCtrl', ['testSvc', testApp.testCtrl]);
和控制器
/// <reference path="../Scripts/angular.d.ts" />
/// <reference path="testSvc.ts" />
module testApp{
export class testCtrl {
public someText:string;
public httpData:any;
public urlName:string;
private data:IData;
static $inject = ['testSvc'];
constructor(testSvc) {
this.someText = 'I am in scope'
this.data = testSvc.getData();
this.httpData = {
putFunc: this.data.putFunc,
expectPUTFunc: this.data.expectPUTFunc
}
this.urlName = this.data.urlName;
}
}}
和服务
/// <reference path="../Scripts/angular.d.ts" />
/// <reference path="testCtrl.ts" />
interface IData{
urlName:string;
putFunc:string;
expectPUTFunc:string;
}
module testApp{
export class testSvc {
public data:IData;
static $inject = ['$http', 'url'];
constructor(private $http, url) {
this.data = {
urlName:url,
putFunc: typeof $http.put,
expectPUTFunc: typeof $http.expectPUT
}
}
getData(){
return this.data;
}
}}
和我的html中的这些脚本声明
<script type="text/javascript" src="../Scripts/angular.js"></script>
<script src="testSvc.js"></script>
<script src="testCtrl.js"></script>
<script src="testApp.js"></script>
当我运行此应用程序时,控制器永远不会收到它对testSvc.getData()的依赖,因为testSvc未定义。我哪里错了?

工厂必须返回服务工厂函数,但是您将返回Service类而不实例化它。您需要更改代码以创建传递$http
和url
的实例,如下所示:
angular.module('testApp').factory('testSvc',
['$http', 'url', ($http, url) => new testApp.testSvc($http, url)]);
也只是一个注释,但您没有将getData()
的返回类型指定为IData
,因此这会产生警告。 getData() : IData

您可以将testSvc
课程保持不变,并使用service(class)
代替factory(fn)
。服务注册您的构造函数,因此您不必新建它并在三个不同的地方提供您注入的服务。
angular.module('testApp').service('testSvc', testApp.testSvc);
