Question

我们正在构建一个使用withCredentials标志的应用。引用this问题，我们可以使用withCredentials标志。现在我试图用mockbackend对服务进行单元测试。只要我删除withCredentials标志，我就能使一切正常。

我的服务：

@Injectable()
export class AccountService {
  public productParams;

  constructor(
    private http: Http) {
    // This allows the cookie to be set and sent.
    // It appears that once the cookie is set with login, it works for each call (even in other services)
     let _build = (<any>http)._backend._browserXHR.build;
     (<any>http)._backend._browserXHR.build = () => {
       let _xhr = _build();
       _xhr.withCredentials = true;
       return _xhr;
     };
  }
}

我的spec文件：

let service;

beforeEachProviders(() => [
    AccountService,
    BaseRequestOptions,
    MockBackend,
    provide(Http, {
        deps: [MockBackend, BaseRequestOptions],
        useFactory: (backend: MockBackend, defaultOptions: BaseRequestOptions) => {
            return new Http(backend, defaultOptions);
        },

    }),
]);

beforeEach(inject([AccountService, MockBackend], (s: AccountService, backend: MockBackend) => {
    service = s;
    const baseResponse = new Response(new ResponseOptions({ body: 'got response' }));
    backend.connections.subscribe((c: MockConnection) => c.mockRespond(baseResponse));
}));

it('should return mocked response', () => {
    service.getUsers().subscribe((res: Response) => {
        expect(res.text()).toBe('got response');
    });
});

我猜测问题是因为withCredentials标志在我的模拟后端没有被嘲笑。那我该怎么做？或者我可以用不同的方式设置http withCredentials标志吗？

错误：

     6) should return mocked response
