本文为大家分享的是node.js端口转发实现代码，供大家参考，具体内容如下

#!/sbin/node var net = require('net'); function proxyPort(srcport,destServer,destport) { var server = net.createServer(function(c) { //'connection' listener c.on('end', function() { console.log('src disconnected'); }); var client = net.connect({port: destport,host:destServer},function() { //'connect' listener console.log('ok....'); c.on('data', function(data) { console.log(data.length); client.write(data); }); }); client.on('error', function(err) { console.log("dest=" + err); c.destroy(); }); c.on('error', function(err) { console.log("src" + err); client.destroy(); }); client.on('data', function(data) { c.write(data); }); client.on('end', function() { console.log('dest disconnected '); }); }); server.listen(srcport, function() { //'listening' listener console.log('server bound' + srcport); }); } var params = process.argv; if(params.length != 5){ console.log("node port.js srcport destserver destport "); return; } proxyPort(params[2],params[3],params[4]); console.log(process.argv);

以上就是本文的全部内容，希望对大家的学习有所帮助。
