处理Server响应的HttpClientInboundHandler：
复制代码
package com.netty.test;
import io.netty.buffer.ByteBuf;
import io.netty.channel.ChannelHandlerContext;
import io.netty.channel.ChannelInboundHandlerAdapter;
import io.netty.handler.codec.http.HttpContent;
import io.netty.handler.codec.http.HttpHeaders;
import io.netty.handler.codec.http.HttpResponse;
public class HttpClientInboundHandler extends ChannelInboundHandlerAdapter {
@Override
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
if (msg instanceof HttpResponse)
{
HttpResponse response = (HttpResponse) msg;
System.out.println("CONTENT_TYPE:" + response.headers().get(HttpHeaders.Names.CONTENT_TYPE));
}
if(msg instanceof HttpContent)
{
HttpContent content = (HttpContent)msg;
ByteBuf buf = content.content();
System.out.println(buf.toString(io.netty.util.CharsetUtil.UTF_8));
buf.release();
}
}
}
