类 HttpServerKeepAliveHandler

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.channel.ChannelDuplexHandler

io.netty.handler.codec.http.HttpServerKeepAliveHandler

所有已实现的接口:

ChannelHandler, ChannelInboundHandler, ChannelOutboundHandler

public class HttpServerKeepAliveHandler
extends ChannelDuplexHandler

HttpServerKeepAliveHandler helps close persistent connections when appropriate.

The server channel is expected to set the proper 'Connection' header if it can handle persistent connections. HttpServerKeepAliveHandler will automatically close the channel for any LastHttpContent that corresponds to a client request for closing the connection, or if the HttpResponse associated with that LastHttpContent requested closing the connection or didn't have a self defined message length.

Since HttpServerKeepAliveHandler expects HttpObjects it should be added after HttpServerCodec but before any other handlers that might send a HttpResponse.

  ChannelPipeline p = ...;
  ...
  p.addLast("serverCodec", new HttpServerCodec());
  p.addLast("httpKeepAlive", new HttpServerKeepAliveHandler());
  p.addLast("aggregator", new HttpObjectAggregator(1048576));
  ...
  p.addLast("handler", new HttpRequestHandler());

channelRead

public void channelRead(ChannelHandlerContext ctx,
                        java.lang.Object msg)
                 throws java.lang.Exception

从类复制的说明: ChannelInboundHandlerAdapter

Calls ChannelHandlerContext.fireChannelRead(Object) to forward to the next ChannelInboundHandler in the ChannelPipeline. Sub-classes may override this method to change behavior.

指定者:

channelRead 在接口中 ChannelInboundHandler

覆盖:

channelRead 在类中 ChannelInboundHandlerAdapter

抛出:

java.lang.Exception

write

public void write(ChannelHandlerContext ctx,
                  java.lang.Object msg,
                  ChannelPromise promise)
           throws java.lang.Exception

从类复制的说明: ChannelDuplexHandler

Calls ChannelOutboundInvoker.write(Object, ChannelPromise) to forward to the next ChannelOutboundHandler in the ChannelPipeline. Sub-classes may override this method to change behavior.

指定者:

write 在接口中 ChannelOutboundHandler

覆盖:

write 在类中 ChannelDuplexHandler

参数:

ctx - the ChannelHandlerContext for which the write operation is made

msg - the message to write

promise - the ChannelPromise to notify once the operation completes

抛出:

java.lang.Exception - thrown if an error occurs
