|
|
*
|
|
* The `HTTP_BINDINGS` 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 {bootstrap, Component, NgFor, View} from 'angular2/angular2';
|
|
* import {HTTP_BINDINGS, Http} from 'angular2/http';
|
|
*
|

|
|
* selector: 'app',
|
|
* bindings: [HTTP_BINDINGS]
|
|
* })

|
|
* <li *ng-for="#person of people">
|
|
* {{person.name}}

* `,

|
|
* 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_BINDINGS` is the {@link Http} class.
|
|
* However, other bindings required by `Http` are included,
|
|
* which may be beneficial to override in certain cases.
|
|
*
|
|
* The bindings included in `HTTP_BINDINGS` include:
|
|
* * {@link Http}
|
|
* * {@link XHRBackend}
|
|
* * `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 binding for {@link RequestOptions} should
|
|
* be added in the same injector as `HTTP_BINDINGS`.
|
|
*
|
|
* ### Example ([live demo](http://plnkr.co/edit/aCMEXi?p=preview))
|
|
*
|
|
* ```
|
|
* import {bind, bootstrap} from 'angular2/angular2';
|
|
* import {HTTP_BINDINGS, BaseRequestOptions, RequestOptions} from 'angular2/http';
|
|
*
|
|
* class MyOptions extends BaseRequestOptions {
|
|
* search: string = 'coreTeam=true';
|
|
* }
|
|
*
|
|
* bootstrap(App, [HTTP_BINDINGS, bind(RequestOptions).toClass(MyOptions)])
|
|
* .catch(err => console.error(err));
|
|
* ```
|
|
*
|
|
* Likewise, to use a mock backend for unit tests, the {@link XHRBackend}
|
|
* binding should be bound to {@link MockBackend}.
|
|
*
|
|
* ### Example ([live demo](http://plnkr.co/edit/7LWALD?p=preview))
|
|
*
|
|
* ```
|
|
* import {bind, Injector} from 'angular2/angular2';
