      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};
      
      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
      
      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
