All Implemented Interfaces:

@ManagedObject
public class HTTP2Client
extends ContainerLifeCycle

HTTP2Client provides an asynchronous, non-blocking implementation to send HTTP/2 frames to a server.

Typical usage:

 // Create and start HTTP2Client.
 HTTP2Client client = new HTTP2Client();
 SslContextFactory sslContextFactory = new SslContextFactory();
 client.addBean(sslContextFactory);
 client.start();

 // Connect to host.
 String host = "webtide.com";
 int port = 443;

 FuturePromise<Session> sessionPromise = new FuturePromise<>();
 client.connect(sslContextFactory, new InetSocketAddress(host, port), new ServerSessionListener.Adapter(), sessionPromise);

 // Obtain the client Session object.
 Session session = sessionPromise.get(5, TimeUnit.SECONDS);

 // Prepare the HTTP request headers.
 HttpFields requestFields = new HttpFields();
 requestFields.put("User-Agent", client.getClass().getName() + "/" + Jetty.VERSION);
 // Prepare the HTTP request object.
 MetaData.Request request = new MetaData.Request("PUT", new HttpURI("https://" + host + ":" + port + "/"), HttpVersion.HTTP_2, requestFields);
 // Create the HTTP/2 HEADERS frame representing the HTTP request.
 HeadersFrame headersFrame = new HeadersFrame(request, null, false);

 // Prepare the listener to receive the HTTP response frames.
 Stream.Listener responseListener = new new Stream.Listener.Adapter()
 {
      @Override
      public void onHeaders(Stream stream, HeadersFrame frame)
      {
          System.err.println(frame);
      }

      @Override
      public void onData(Stream stream, DataFrame frame, Callback callback)
      {
          System.err.println(frame);
          callback.succeeded();
      }
 };

 // Send the HEADERS frame to create a stream.
 FuturePromise<Stream> streamPromise = new FuturePromise<>();
 session.newStream(headersFrame, streamPromise, responseListener);
 Stream stream = streamPromise.get(5, TimeUnit.SECONDS);

 // Use the Stream object to send request content, if any, using a DATA frame.
 ByteBuffer content = ...;
 DataFrame requestContent = new DataFrame(stream.getId(), content, true);
 stream.data(requestContent, Callback.Adapter.INSTANCE);

 // When done, stop the client.
 client.stop();
