/**
|
|
* 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: `
|
|
* <div>
|
|
* <h1>People</h1>
|
|
* <ul>
|
|
* <li *ngFor="let person of people">
|
|
* {{person.name}}
|
|
* </li>
|
|
* </ul>
|
|
* </div>
|
|
* `,
|
|
* 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.
|
|
*

|

|
|
*
|
|
* ```
|
|
* 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));
|
|
* ```
