Unity UDP协议_unity udp_cmd

不熟悉TCP/UDP协议的同学可以参考这篇文章：http://blog.csdn.net/li_ning_/article/details/52117463

话不多少说，服务器端代码如下：

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Net;
using System.Net.Sockets;
using System.Threading;
 
public class Server : MonoBehaviour {
 
    private UdpClient udpClient;
 
    private bool isRunningThread;
 
    private Thread thread_udpRecv;
 
    private Queue<string> queue_udpMessage;
 
	// Use this for initialization
	void Start () {
        queue_udpMessage = new Queue<string>();
        CreateUdpListener();
	}
	
	// Update is called once per frame
	void Update () {
	    if(queue_udpMessage.Count > 0)
        {
            string cmd = queue_udpMessage.Dequeue();
            print(cmd);
 
            DoByCommand(cmd);
        }
	}
 
    void OnDisable()
    {
        isRunningThread = false;
        udpClient.Close();
    }
 
    private void CreateUdpListener()
    {
        isRunningThread = true;
 
        udpClient = new UdpClient(ConfiInfo.UdpPort);
        thread_udpRecv = new Thread(ReciveMessages);
        thread_udpRecv.Start();
    }
 
    private void ReciveMessages()
    {
        while(isRunningThread)
        {
            try
            {
                IPEndPoint remoteIpep = new IPEndPoint(IPAddress.Any, ConfiInfo.UdpPort);
                byte[] bytRecv = udpClient.Receive(ref remoteIpep);
                string message = System.Text.Encoding.Default.GetString(bytRecv, 0, bytRecv.Length);
                
                queue_udpMessage.Enqueue(message);
            }
            catch(System.Exception ex)
            {
                print(ex.Message);
                break;
            }
        }
    }
 
    private void DoByCommand(string cmd)
    {
        //string tmp = cmd.ToLower();
 
        switch(cmd)
        {
            case "TransPortPhoto": ReceivePhoto(); break;  //图片数据流的接收并显示
        }
    }
 
    private void ReceivePhoto()
    {
        Debug.Log("显示图片！");
    }
}

客户端代码如下：

using UnityEngine;
using System.Collections;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.IO;
using System;
 
public class Client : MonoBehaviour
{
    [SerializeField]
    private string fileName;
 
    private string pathPhoto;
 
    private Socket socket;
    private IPEndPoint serverPoint;
 
    // Use this for initialization
    void Start()
    {
        pathPhoto = Application.dataPath + ConfiInfo.pathPhoto;
 
        CreateCilent();
    }
 
    // Update is called once per frame
    void Update()
    {
 
    }
 
    void OnDestory()
    {
        socket.Close();
    }
 
    public void TransPortPhotoMessage()    //发送数据
    {
        string pathFile = pathPhoto + fileName;
        TcpSendFileStream(pathFile);
 
        UdpSendMessage("TransPortPhoto");
    }
 
    private void TcpSendFileStream(string pathFile)   //发送文件数据流
    {
        print("EnterUdpSendFileStream");
 
 
 
        print("UdpSendFileStreamEnd");
    }
 
    private void UdpSendMessage(string message)   //发送字符串指令
    {
        try
        {
            byte[] bytBuffer = Encoding.UTF8.GetBytes(message);
            socket.SendTo(bytBuffer, serverPoint);
        }
        catch (Exception e)
        {
            Debug.Log(e.Message);
        }
 
        print(message);
    }
 
    private void CreateCilent()
    {
        socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
        serverPoint = new IPEndPoint(IPAddress.Parse(ConfiInfo.serverIP), ConfiInfo.UdpPort);
        socket.Connect(serverPoint);
    }
}
