在unity3d中接受MQTT消息协议数据C# .net,M2Mqtt

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 frame
	void 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);
    }
}
