Members

readyState: ReadyState

Describes the state of the connection, based on XMLHttpRequest.readyState, but with additional states. For example, state 5 indicates an aborted connection.

request: Request

Request

instance used to create the connection.

response: ReplaySubject<Response>

EventEmitter

of Response. Can be subscribed to in order to be notified when a response is available.

mockRespond(res: Response)

Sends a mock response to the connection. This response is the value that is emitted to the EventEmitter returned by Http.

Example

var connection;
backend.connections.subscribe(c => connection = c);
http.request('data.json').subscribe(res => console.log(res.text()));
connection.mockRespond(new Response(new ResponseOptions({ body: 'fake response' }))); //logs
'fake response'

mockDownload(res: Response)

Not yet implemented!

Sends the provided Response to the downloadObserver of the Request associated with this connection.

mockError(err?: Error)

Emits the provided error object as an error to the Response EventEmitter returned from Http.

Example

var connection;
backend.connections.subscribe(c => connection = c);
http.request('data.json').subscribe(res => res, err => console.log(err)));
connection.mockError(new Error('error'));
