/**
* 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],
* templateUrl: 'people.html'
* })
* 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));
* ```
*
* @deprecated see https://angular.io/guide/http
* @publicApi
