BaseRequestOptions

Subclass of RequestOptions, with default values.

弃用说明

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

class BaseRequestOptions extends RequestOptions { // 继承自 http/RequestOptions constructor(opts: RequestOptionsArgs = {}) method: RequestMethod | string | null headers: Headers | null body: any url: string | null params: URLSearchParams search: URLSearchParams withCredentials: boolean | null responseType: ResponseContentType | null merge(options?: RequestOptionsArgs): RequestOptions }

说明

Default values:

This class could be extended and bound to the RequestOptionsclass when configuring an Injector, in order to override the default options used by Httpto create and send Requests.

import {BaseRequestOptions, RequestOptions} from '@angular/http'; class MyOptions extends BaseRequestOptions { search: string = 'coreTeam=true'; } {provide: RequestOptions, useClass: MyOptions};

The options could also be extended when manually creating a Requestobject.

import {BaseRequestOptions, Request, RequestMethod} from '@angular/http'; const options = new BaseRequestOptions(); const req = new Request(options.merge({ method: RequestMethod.Post, url: 'https://google.com' })); console.log('req.method:', RequestMethod[req.method]); // Post console.log('options.url:', options.url); // null console.log('req.url:', req.url); // https://google.com
