Examples with DefaultHttp2WindowUpdateFrame io.netty.handler.codec.http2.DefaultHttp2WindowUpdateFrame used on opensource projects

Example 1 with DefaultHttp2WindowUpdateFrame

use of io.netty.handler.codec.http2.DefaultHttp2WindowUpdateFrame in project netty by netty.

the class Http2FrameCodecTest method upgradeWithoutFlowControlling.

@Test
public void upgradeWithoutFlowControlling() throws Exception {
    channel.pipeline().addAfter(frameCodec.ctx.name(), null, new ChannelInboundHandlerAdapter() {

        @Override
        public void channelRead(final ChannelHandlerContext ctx, Object msg) throws Exception {
            if (msg instanceof Http2DataFrame) {
                // Simulate consuming the frame and update the flow-controller.
                Http2DataFrame data = (Http2DataFrame) msg;
                ctx.writeAndFlush(new DefaultHttp2WindowUpdateFrame(data.initialFlowControlledBytes()).stream(data.stream())).addListener(new ChannelFutureListener() {

                    @Override
                    public void operationComplete(ChannelFuture future) throws Exception {
                        Throwable cause = future.cause();
                        if (cause != null) {
                            ctx.fireExceptionCaught(cause);
                        }
                    }
                });
            }
            ReferenceCountUtil.release(msg);
        }
    });
    frameInboundWriter.writeInboundHeaders(Http2CodecUtil.HTTP_UPGRADE_STREAM_ID, request, 31, false);
    // Using reflect as the constructor is package-private and the class is final.
    Constructor<UpgradeEvent> constructor = UpgradeEvent.class.getDeclaredConstructor(CharSequence.class, FullHttpRequest.class);
    // Check if we could make it accessible which may fail on java9.
    Assumptions.assumeTrue(ReflectionUtil.trySetAccessible(constructor, true) == null);
    String longString = new String(new char[70000]).replace("\0", "*");
    DefaultFullHttpRequest request = new DefaultFullHttpRequest(HttpVersion.HTTP_1_1, HttpMethod.GET, "/", bb(longString));
    HttpServerUpgradeHandler.UpgradeEvent upgradeEvent = constructor.newInstance("HTTP/2", request);
    channel.pipeline().fireUserEventTriggered(upgradeEvent);
}

Example 2 with DefaultHttp2WindowUpdateFrame

use of io.netty.handler.codec.http2.DefaultHttp2WindowUpdateFrame in project netty by netty.

the class HelloWorldHttp2Handler method onDataRead.

/**
 * If receive a frame with end-of-stream set, send a pre-canned response.
 */
private static void onDataRead(ChannelHandlerContext ctx, Http2DataFrame data) throws Exception {
    Http2FrameStream stream = data.stream();
    if (data.isEndStream()) {
        sendResponse(ctx, stream, data.content());
    } else {
        // We do not send back the response to the remote-peer, so we need to release it.
        data.release();
    }
    // Update the flowcontroller
    ctx.write(new DefaultHttp2WindowUpdateFrame(data.initialFlowControlledBytes()).stream(stream));
