All Implemented Interfaces:
io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler, io.netty.channel.ChannelOutboundHandler
public class HttpStreamsClientHandler extends io.netty.channel.ChannelDuplexHandler
Handler that converts written StreamedHttpRequest messages into HttpRequest messages followed by HttpContent messages and reads HttpResponse messages followed by HttpContent messages and produces StreamedHttpResponse messages. This allows request and response bodies to be handled using reactive streams. There are two types of messages that this handler accepts for writing, StreamedHttpRequest and FullHttpRequest. Writing any other messages may potentially lead to HTTP message mangling. There are two types of messages that this handler will send down the chain, StreamedHttpResponse, and FullHttpResponse. If ChannelOption.AUTO_READ is false for the channel, then any StreamedHttpResponse messages must be subscribed to consume the body, otherwise it's possible that no read will be done of the messages. As long as messages are returned in the order that they arrive, this handler implicitly supports HTTP pipelining.
