/**
* Provides a basic set of injectables to use the {@link Http} service in any application.
*
* The `HTTP_PROVIDERS` should be included either in a component's injector,
* or in the root injector when bootstrapping an application.
*
* ### Example ([live demo](http://plnkr.co/edit/snj7Nv?p=preview))
*
* ```
* import {Component} from '@angular/core';
* import {bootstrap} from '@angular/platform-browser/browser';
* import {NgFor} from '@angular/common';
* import {HTTP_PROVIDERS, Http} from '@angular/http';
*
* @Component({
* selector: 'app',
* providers: [HTTP_PROVIDERS],
* template: `
*
*
People
*
*
* {{person.name}}
*
*
*
* `,
* directives: [NgFor]
* })
* export class App {
* people: Object[];
* constructor(http:Http) {
* http.get('people.json').subscribe(res => {
* this.people = res.json();
* });
* }
* active:boolean = false;
* toggleActiveState() {
* this.active = !this.active;
* }
* }
*
* bootstrap(App)
* .catch(err => console.error(err));
* ```
*
* The primary public API included in `HTTP_PROVIDERS` is the {@link Http} class.
* However, other providers required by `Http` are included,
* which may be beneficial to override in certain cases.
*
* The providers included in `HTTP_PROVIDERS` include:
* * {@link Http}
* * {@link XHRBackend}
* * {@link XSRFStrategy} - Bound to {@link CookieXSRFStrategy} class (see below)
* * `BrowserXHR` - Private factory to create `XMLHttpRequest` instances
* * {@link RequestOptions} - Bound to {@link BaseRequestOptions} class
* * {@link ResponseOptions} - Bound to {@link BaseResponseOptions} class
*
* There may be cases where it makes sense to extend the base request options,
* such as to add a search string to be appended to all URLs.
* To accomplish this, a new provider for {@link RequestOptions} should
* be added in the same injector as `HTTP_PROVIDERS`.
*
* ### Example ([live demo](http://plnkr.co/edit/aCMEXi?p=preview))
*
* ```
* import {provide} from '@angular/core';
* import {bootstrap} from '@angular/platform-browser/browser';
* import {HTTP_PROVIDERS, BaseRequestOptions, RequestOptions} from '@angular/http';
*
* class MyOptions extends BaseRequestOptions {
* search: string = 'coreTeam=true';
* }
*
* bootstrap(App, [HTTP_PROVIDERS, {provide: RequestOptions, useClass: MyOptions}])
* .catch(err => console.error(err));
* ```
*
* Likewise, to use a mock backend for unit tests, the {@link XHRBackend}
* provider should be bound to {@link MockBackend}.
*
* ### Example ([live demo](http://plnkr.co/edit/7LWALD?p=preview))
*
* ```
* import {provide} from '@angular/core';
* import {bootstrap} from '@angular/platform-browser/browser';
* import {HTTP_PROVIDERS, Http, Response, XHRBackend} from '@angular/http';
* import {MockBackend} from '@angular/http/testing';
*
* var people = [{name: 'Jeff'}, {name: 'Tobias'}];
*
* var injector = Injector.resolveAndCreate([
* HTTP_PROVIDERS,
* MockBackend,
* {provide: XHRBackend, useExisting: MockBackend}
* ]);
* var http = injector.get(Http);
* var backend = injector.get(MockBackend);
*
* // Listen for any new requests
* backend.connections.observer({
* next: connection => {
* var response = new Response({body: people});
* setTimeout(() => {
* // Send a response to the request
* connection.mockRespond(response);
* });
* }
* });
*
* http.get('people.json').observer({
* next: res => {
* // Response came from mock backend
* console.log('first person', res.json()[0].name);
* }
* });
* ```
*
* `XSRFStrategy` allows customizing how the application protects itself against Cross Site Request
* Forgery (XSRF) attacks. By default, Angular will look for a cookie called `'XSRF-TOKEN'`, and set
* an HTTP request header called `'X-XSRF-TOKEN'` with the value of the cookie on each request,
* allowing the server side to validate that the request comes from its own front end.
*
* Applications can override the names used by configuring a different `XSRFStrategy` instance. Most
* commonly, applications will configure a `CookieXSRFStrategy` with different cookie or header
* names, but if needed, they can supply a completely custom implementation.
*
* See the security documentation for more information.
*
* ### Example
*
* ```
* import {provide} from '@angular/core';
* import {bootstrap} from '@angular/platform-browser/browser';
* import {HTTP_PROVIDERS, XSRFStrategy, CookieXSRFStrategy} from '@angular/http';
*
* bootstrap(
* App,
* [HTTP_PROVIDERS, {provide: XSRFStrategy,
* useValue: new CookieXSRFStrategy('MY-XSRF-COOKIE-NAME', 'X-MY-XSRF-HEADER-NAME')}])
* .catch(err => console.error(err));
* ```
