Class Http2DataChunkedInput

java.lang.Object

io.netty.handler.codec.http2.Http2DataChunkedInput

All Implemented Interfaces:

io.netty.handler.stream.ChunkedInput<Http2DataFrame>

public final class Http2DataChunkedInput
extends Object
implements io.netty.handler.stream.ChunkedInput<Http2DataFrame>

A ChunkedInput that fetches data chunk by chunk for use with HTTP/2 Data Frames.

Each chunk from the input data will be wrapped within a Http2DataFrame. At the end of the input data, Http2DataFrame.isEndStream() will be set to true and will be written.

     public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
         if (msg instanceof Http2HeadersFrame) {
             Http2HeadersFrame http2HeadersFrame = (Http2HeadersFrame) msg;

             Http2HeadersFrame response = new DefaultHttp2HeadersFrame(new DefaultHttp2Headers().status("200"));
             response.stream(http2HeadersFrame.stream());
             ctx.write(response);

             ChannelFuture sendFileFuture = ctx.writeAndFlush(new Http2DataChunkedInput(
                     new ChunkedFile(new File(("/home/meow/cats.mp4"))), http2HeadersFrame.stream()));
         }
     }
