我正在努力在Angular 2中制作REST Api请求。
我的API本身在消费时起作用:
http://localhost:8080/tshirts
它会让我回头:
[{
"Id": 1,
"Title": "honey blanket",
"PrintTechnique": "sublimation"
}, {
"Id": 2,
"Title": "tell your story",
"PrintTechnique": "screen print"
}]
现在,我尝试在Angular中实现请求,受到documentation:
的启发import {Injectable, Injector} from 'angular2/core';
import {HTTP_PROVIDERS, Http, Request, RequestMethod} from 'angular2/http';
@Injectable()
export class TshirtService {
constructor(public http:Http) {}
getTshirts() {
var tshirts = this.http.request(new Request({
method: RequestMethod.Get,
url: 'http://localhost:8080/tshirts'
}));
console.log(tshirts);
return tshirts;
}
}
根据我的界面,结果应该是Tshirts[]
类型:
export interface Tshirt {
Id: number;
Title: string;
PrintTechnique: string;
}
但是,控制台不会打印Tshirt对象,而是打印Observable
:
Observable {_isScalar: false}
_isScalar:false
_subscribe:(responseObserver)
__proto__:Object
我做错了什么?
答案 0 :(得分:-1)
我认为响应可观察性需要通过类似......
之类的方式进行映射this.http.request(...)
.map(response => response.json());
