具体关于MQTT是什么具体就不说了，百度一下，你就知道。这里用的是M2Mqtt的类库。可以去查官网然后git下来自己生成一下。接下来直接上unity客户端的本地代码：

需要提前导入生成的DLL。

using UnityEngine;using System.Collections;using System.Net;using System.Text;using uPLibrary.Networking.M2Mqtt;using uPLibrary.Networking.M2Mqtt.Messages;public class Mqtt : MonoBehaviour{    private MqttClient mqttClient;    void Awake()    {        //链接服务器        mqttClient = new MqttClient(IPAddress.Parse("192.168.1.163"));               //注册服务器返回信息接受函数        mqttClient.MqttMsgPublishReceived += client_MqttMsgPublishReceived;        //客户端ID  一个字符串        mqttClient.Connect("zsc");        //监听FPS字段的返回数据        mqttClient.Subscribe(new string[] { "fps" }, new byte[] { MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE });    }void Start () {}// Update is called once per framevoid Update () {    if (Input.GetMouseButtonDown(0))    {            //这个字符串是向服务器发送的数据信息            string strValue = "123";            // 发送一个内容是123 字段是klabs的信息            mqttClient.Publish("klabs", Encoding.UTF8.GetBytes(strValue));             Debug.Log("发送数据123");    }}    static void client_MqttMsgPublishReceived(object sender, MqttMsgPublishEventArgs e)    {        // handle message received        Debug.Log("返回数据");        string msg = System.Text.Encoding.Default.GetString(e.Message);        Debug.Log(msg);    }}
