Request

Creates Request instances from provided values.

弃用说明

see https://angular.io/guide/http

class Request extends Body { constructor(requestOptions: RequestArgs) method: RequestMethod headers: Headers url: string withCredentials: boolean responseType: ResponseContentType detectContentType(): ContentType detectContentTypeFromBody(): ContentType getBody(): any }

说明

The Request's interface is inspired by the Request constructor defined in the Fetch Spec, but is considered a static value whose body can be accessed many times. There are other differences in the implementation, but this is the most significant.

Request instances are typically created by higher-level classes, like Httpand Jsonp, but it may occasionally be useful to explicitly create Request instances. One such example is when creating services that wrap higher-level services, like Http, where it may be useful to generate a Request with arbitrary headers and search params.

import {Injectable, Injector} from '@angular/core'; import {HTTP_PROVIDERS, Http, Request, RequestMethod} from '@angular/http'; @Injectable() class AutoAuthenticator { constructor(public http:Http) {} request(url:string) { return this.http.request(new Request({ method: RequestMethod.Get, url: url, search: 'password=123' })); } } var injector = Injector.resolveAndCreate([HTTP_PROVIDERS, AutoAuthenticator]); var authenticator = injector.get(AutoAuthenticator); authenticator.request('people.json').subscribe(res => { //URL should have included '?password=123' console.log('people', res.json()); });
