Method Details

execute

public SuccessfulHttpResponse execute(HttpRequest request)
                               throws HttpException

Description copied from interface: HttpClient

Executes a given HTTP request synchronously and returns the response. This method blocks until the entire response is received.

Specified by:

execute in interface HttpClient

Parameters:

request - the HTTP request to be executed.

Returns:

a SuccessfulHttpResponse containing the response data for successful HTTP requests (2XX status codes)

Throws:

HttpException - if the server returns a client (4XX) or server (5XX) error response

execute

public void execute(HttpRequest request,
 ServerSentEventListener delegateListener)

Description copied from interface: HttpClient

Executes a given HTTP request asynchronously with server-sent events (SSE) handling. This method returns immediately while processing continues on a separate thread. Events are processed through the provided ServerSentEventListener.

The execution flow is as follows:

1. The request is initiated asynchronously
2. Received SSE data is parsed using the DefaultServerSentEventParser
3. Parsed events are delivered to the listener's appropriate methods
4. If an error occurs, ServerSentEventListener.onError(Throwable) is called

If any exception is thrown from the listener's methods, the stream processing will be terminated and no further events will be processed.

Specified by:

execute in interface HttpClient

Parameters:

request - the HTTP request to be executed.

delegateListener - the listener to receive parsed events and error notifications.
