关于UDP socket 接收到的数据转HEX的问题，

    var dgram = require("dgram");

var server = dgram.createSocket("udp4");

server.on("message", function (msg, rinfo) {
  console.log("server got: " + msg + " from " +
    rinfo.address + ":" + rinfo.port);
});

server.on("listening", function () {
  var address = server.address();
  console.log("server listening " +
      address.address + ":" + address.port);
});

server.bind(3210);

接收到的数据msg如何转为 hex? 谢谢

通过

len = buf.write(msg, 0);
console.log(buf.toString('hex', 0, len));

解决了。
