我有一个非常简单的网页:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<title></title>
</head>
<body ng-app="nawApp">
<div ng-controller="StudentUse">
{{fullname}}
</div>
<script src="../Scripts/angular.js"></script>
<script src="../Scripts/angular-route.js"></script>
<script src="../Scripts/app.js"></script>
<script src="StudentUse.js"></script>
<script src="ServiceHttp.js"></script>
</body>
</html>
我的控制器 StundentUse 。
/// <reference path="../scripts/app.ts" />
/// <reference path="ServiceHttp.ts" />
/// <reference path="../scripts/typescript/angular.d.ts" />
/// <reference path="Student.ts" />
module nawApp {
export interface IStundentScope extends ng.IScope {
returnData: string;
}
export class StudentUse {
static $inject = ['$scope', 'ServiceHttp'];
constructor($scope: IStundentScope, private serviceHttp: nawApp.ServiceHttp) {
$scope.returnData = serviceHttp.hello();
}
}
// StudentUse.$inject = ['$scope', 'ServiceHttp'];
nawApp.app.controller('StudentUse', StudentUse);
}
我有另一个名为 ServiceHttp.ts 的文件,由上层代码使用。 &#34; ServiceHttp.ts&#34;将来应该是某种REST接口,但到目前为止它只是返回一个&#34; Hello World&#34;字符串:
/// <reference path="../scripts/app.ts" />
module nawApp {
export class ServiceHttp {
constructor() {}
hello(): string {
return "Hello world";
}
}
nawApp.app.controller('ServiceHttp', ServiceHttp);
}
如果我启动我的网页,切换到开发者控制台,我会收到一个错误:
错误:[$ injector:unpr]未知提供商:serviceHttpProvider&lt; - serviceHttp
我做了一些调查,但我看不出有效的例子与解决方案之间的区别......: - (
任何提示?
谢谢!
编辑: 这应该是 ServiceHttp.ts 中函数的最终代码:
exampleFunction():string {
this.http.get(URL).success(function (data, status, headers, config) {
try {
return data;
}
catch (err) {
return err;
}
}).error(function (data, status, headers, config) {
return status;
});
return "";
}
答案 0 :(得分:1)
首先,我想建议在顶部
中包含angular.d.ts/// <reference path="../scripts/typescript/angular.d.ts" />
/// <reference path="../scripts/app.ts" />
/// <reference path="ServiceHttp.ts" />
/// <reference path="Student.ts" />
对于服务,您应该像这样创建
module nawApp {
export class ServiceHttp {
private http: ng.IHttpService;
private q: ng.IQService;
private log: ng.ILogService;
constructor($http: ng.IHttpService,$q: ng.IQService,$log: ng.ILogService) {
this.http = $http;
this.q = $q;
this.log = $log;
}
exampleFunction(){
var defer = this.q.defer();
this.http.get('http://example.com').then(
(response: ng.IHttpPromiseCallbackArg<any>) => {
defer.resolve(response);
}
},
(err: ng.IHttpPromiseCallbackArg<any>) => {
defer.reject(err.data);
}
)
return defer.promise;
}
static Factory($http:ng.IHttpService, $q:ng.IQService,$log: ng.ILogService) {
return new ServiceHttp($http, $q, $log);
}
}
}
这是一个服务示例。然后,您需要将您的服务注册到您的应用中
nawApp.app.factory('ServiceHttp', nawApp.ServiceHttp.Factory);
在代码中的某个地方,例如在控制器中,你应该注入你的服务
并在控制器功能
控制器构造函数
private ServiceHttp:any;
constructor(ServiceHttp .... // other dependencies){
this.ServiceHttp = ServiceHttp;
}
ctrl函数中的
someCtrlFunction(){
this.ServiceHttp.exampleFunction().then(function(resp){
// success resolved with your response
})
}
