实现原理

服务端创建socket服务端绑定本地端口(用于客户端连接)
package wu.framework.lazy.cloud.heartbeat.server.netty.socket;


import io.netty.bootstrap.ServerBootstrap;
import io.netty.channel.ChannelFuture;
import io.netty.channel.ChannelFutureListener;
import io.netty.channel.ChannelOption;
import io.netty.channel.EventLoopGroup;
import io.netty.channel.nio.NioEventLoopGroup;
import io.netty.channel.socket.nio.NioServerSocketChannel;
import wu.framework.lazy.cloud.heartbeat.server.netty.filter.NettyServerFilter;

public class NettyOnCloudNettyServerSocket {
    private final EventLoopGroup bossGroup = new NioEventLoopGroup();
    private final EventLoopGroup workerGroup = new NioEventLoopGroup();
    private final NettyServerFilter nettyServerFilter;// 通道业务处理
    private ChannelFuture channelFuture;

    public NettyOnCloudNettyServerSocket(NettyServerFilter nettyServerFilter) {
        this.nettyServerFilter = nettyServerFilter;
    }

    /**
     * 启动服务端
     *
     * @throws Exception
     */
    public void startServer(int serverPort) throws Exception {
        try {

            ServerBootstrap b = new ServerBootstrap();
            b.group(bossGroup, workerGroup).channel(NioServerSocketChannel.class)
                    // 给服务端channel设置属性
                    .option(ChannelOption.SO_BACKLOG, 128)

                    .childOption(ChannelOption.SO_KEEPALIVE, true)
                    .childHandler(nettyServerFilter)
            ;
            channelFuture = b.bind(serverPort).sync();

            channelFuture.addListener((ChannelFutureListener) channelFuture -> {
                // 服务器已启动
            });
            channelFuture.channel().closeFuture().sync();
        } finally {
            shutdown();
            // 服务器已关闭
        }
    }

    public void shutdown() {
        if (channelFuture != null) {
            channelFuture.channel().close().syncUninterruptibly();
        }
        if ((bossGroup != null) && (!bossGroup.isShutdown())) {
            bossGroup.shutdownGracefully();
        }
        if ((workerGroup != null) && (!workerGroup.isShutdown())) {
            workerGroup.shutdownGracefully();
        }
    }
}
客户端通过class NettyClientSocket 连接服务端
package wu.framework.lazy.cloud.heartbeat.client.netty.socket;

}
通过客户端与服务端建立的连接进行访客端口绑定
上述连接会形成一个channel,我们称之为通道(本文中简单叫**心跳通道**)
第一步 页面GUI进行新增访客端口而后将访客端口与客户端绑定(如果客户端已经启动,使用页面客户端下线触发第二步)
第二步 客户端与访客端口绑定后使用**心跳通道** 发送客户端告诉客户端,你帮我绑定你本地真实端口
第三步 访客访问,访客通过访客端口访问数据,此时访客通道打开截取访客发送的数据,然后将数据发送给客户真实通道,数据返回后再返回给访客通道

功能

1.内网穿透
2.服务端自主下发数据到客户端
3.流量监控
