Socket通信 | 易学教程

交互就是比较烦的，涉及的东西还是很多的

使用Socket通信，在局域网中还是比较合适的。

TCP的三次握手差不多也可以保证数据的正确性了，算是比较可靠的了

也参考了网络上其他的一些写法，自己写个测试下，可以通过。

服务器端：

using UnityEngine;
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;

using System.Collections.Generic;

public class Server1
: MonoBehaviour
{
Socket serverSocket;
Socket clientSocket;
Thread clientThread;
Thread t;
// Use this for initialization
void Start()
{
t = new Thread(new ThreadStart(OpenServer));
t.Start();
}

// Update is called once per frame
void Update()
{

}

void OpenServer()
{
IPAddress ipAdr = IPAddress.Parse("127.0.0.1");

//端口号，服务器端和客户端需要保持一致，否则端口访问错误
IPEndPoint ipEp = new IPEndPoint(ipAdr, 8081);
serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
serverSocket.Bind(ipEp);
serverSocket.Listen(10);

while (true)
{
try
{
clientSocket = serverSocket.Accept();

clientThread = new Thread(new ThreadStart(ReceiveData));
clientThread.Start();

}
catch (System.Exception ex)
{
print(ex);
}
}
}

void ReceiveData()
{
bool keepalive = true;
Socket s = clientSocket;
byte[] buffer = new byte[1024];

//根据收听到的客户端套接字向客户端发送信息
IPEndPoint clientep = (IPEndPoint)s.RemoteEndPoint;
//lstServer.Items.Add("Client：" + clientep.Address + "("+clientep.Port+")");
string welcome = "IP为" + clientep.Address + "的客户端连接成功";
byte[] data = new byte[1024];
data = Encoding.UTF8.GetBytes(welcome);
s.Send(data, data.Length, SocketFlags.None);

while (keepalive)
{
//在套接字上接收客户端发送的信息
int bufLen = 0;
try
{
bufLen = s.Available;

s.Receive(buffer, 0, bufLen, SocketFlags.None);
if (bufLen == 0)
continue;
}
catch (Exception ex)
{
Debug.Log("Receive Error:" + ex.Message);
return;
}
clientep = (IPEndPoint)s.RemoteEndPoint;
string clientcommand = System.Text.Encoding.UTF8.GetString(buffer).Substring(0, bufLen);
Debug.Log("服务端收到:" + clientcommand);
//lstServer.Items.Add(clientcommand + "("+clientep.Address + ":"+clientep.Port+")");

}
}
}

搞定

只需建立两个项目工程，一个客户端，一个服务器，分别挂载脚本
