Angular 2 - http get withCredentials

问题:

I found something regarding this, but most examples and explanations are deprecated and it's not applicable to RC1.

import {Injectable} from "@angular/core";
import {Http, HTTP_PROVIDERS, Response, RequestOptions, URLSearchParams} from "@angular/http";
import 'rxjs/add/operator/map';
@Injectable()
export class AuthService {
constructor( private _http: Http ) {}
GetLoggedUser(){
    return this._http.get('http://dev/api/v1/current-user')
     .map((res:Response) => res.json())
} 
} 

I need to make this call exactly as this legacy code:

$(document).ready(function() {
                    jQuery.ajax({
                        type: 'GET',
                        url: 'http://dev/api/v1/current-user',
                        xhrFields: {
                            withCredentials: true
                        },
                    }).done(function(data) {
                        $('#user').html(JSON.stringify(data));
                    });
                });

So, basically I need to make the call using withCredentials. Any help ?

回答1:

With RC1 you need to extend the BrowserXhr class:

@Injectable()
export class CustomBrowserXhr extends BrowserXhr {
  constructor() {}
  build(): any {
    let xhr = super.build();
    xhr.withCredentials = true;
    return <any>(xhr);
  }
}

and override the BrowserXhr provider with the extended:

bootstrap(AppComponent, [
  HTTP_PROVIDERS,
  provide(BrowserXhr, { useClass: CustomBrowserXhr })
]);

With the upcoming RC2, you'll be able to use a withCredentials attribute in request options.
