Description

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 Http and 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());
});
