/**
 * Performs http requests using `XMLHttpRequest` as the default backend.
 *
 * `Http` is available as an injectable class, with methods to perform http requests. Calling
 * `request` returns an `Observable` which will emit a single {@link Response} when a
 * response is received.
 *
 * @usageNotes
 * ### Example
 *
 * ```typescript
 * import {Http, HTTP_PROVIDERS} from '@angular/http';
 * import {map} from 'rxjs/operators';
 *
 * @Component({
 *   selector: 'http-app',
 *   viewProviders: [HTTP_PROVIDERS],

 * })
 * class PeopleComponent {
 *   constructor(http: Http) {
 *     http.get('people.json')
 *       // Call map on the response observable to get the parsed people object
 *       .pipe(map(res => res.json()))
 *       // Subscribe to the observable to get the parsed people object and attach it to the
 *       // component
 *       .subscribe(people => this.people = people);

 *
 * ### Example
 *
 * ```
 * http.get('people.json').subscribe((res:Response) => this.people = res.json());
 * ```
 *
 * The default construct used to perform requests, `XMLHttpRequest`, is abstracted as a "Backend" (
 * {@link XHRBackend} in this case), which could be mocked with dependency injection by replacing
 * the {@link XHRBackend} provider, as in the following example:
 *
 * ### Example
 *
 * ```typescript
 * import {BaseRequestOptions, Http} from '@angular/http';
 * import {MockBackend} from '@angular/http/testing';
 * var injector = Injector.resolveAndCreate([
 *   BaseRequestOptions,
 *   MockBackend,
 *   {provide: Http, useFactory:
 *       function(backend, defaultOptions) {
 *         return new Http(backend, defaultOptions);
 *       },
 *       deps: [MockBackend, BaseRequestOptions]}
 * ]);
 * var http = injector.get(Http);
 * http.get('request-from-mock-backend.json').subscribe((res:Response) => doSomething(res));

 * This class is based on the `ResponseInit` description in the [Fetch
 * Spec](https://fetch.spec.whatwg.org/#responseinit).
 *
 * All values are null by default. Typical defaults can be found in the
 * {@link BaseResponseOptions} class, which sub-classes `ResponseOptions`.
 *
 * This class may be used in tests to build {@link Response Responses} for
 * mock responses (see {@link MockBackend}).
 *
 * @usageNotes
 * ### Example
 *
 * ```typescript
 * import {ResponseOptions, Response} from '@angular/http';
 *
 * var options = new ResponseOptions({
 *   body: '{"name":"Jeff"}'
 * });
 * var res = new Response(options);
 *
 * console.log('res.json():', res.json()); // Object {name: "Jeff"}
