您好我是AngularJs 2的新手。
我正在创建简单的应用程序来读取Github API。
当我使用以下文件启动应用程序时,我收到以下错误:
AppComponent.html:1错误TypeError:无法读取未定义的属性'subcribe'
以下是我的服务和组件ts文件。
github.service.ts
import {Injectable} from '@angular/core';
import {Http, Headers} from '@angular/http';
import 'rxjs/add/operator/map';
@Injectable()
export class GithubService{
private username: string;
private client_id = "client_id";
private client_secret = "client_secret";
constructor( private _http: Http){
console.log("Github service is ready...");
this.username = "graphicsmanoj";
}
getUser(){
this._http.get('http://api.github.com/users/'+this.username+'?client_id='+this.client_id+'&client_secret='+this.client_secret).map(res => res.json());
}
}
profile.component.ts
import { Component } from '@angular/core';
import { GithubService } from '../services/github.service';
@Component({
moduleId: module.id,
selector: 'profile',
templateUrl: 'profile.component.html',
})
export class ProfileComponent {
constructor(private _githubService: GithubService){
this._githubService.getUser().subcribe(user => {
console.log(user);
})
}
}
非常感谢您提供的解决方案。

它应该是 subscribe
,
更改为
this._githubService.getUser().subscribe(user => {
console.log(user);
})
并将您的服务更改为
getUser(): Observable<any> {
return this._http.get('http://api.github.com/users/'+this.username+'?client_id='+this.client_id+'&client_secret='+this.client_secret).map(res => res.json());
}

在GithubService
中,您需要返回this._http.get
的结果。
@Injectable()
export class GithubService{
...
getUser(): Observable<any> {
// return was missing
return this._http.get('http://api.github.com/users/'+this.username+'?client_id='+this.client_id+'&client_secret='+this.client_secret).map(res => res.json());
}
}
