Unity Socket Accept卡死的问题

烟雨

许多在unity里使用过Socket传输网络数据的人，也许都遇到过，VS里好好能运行的代码，在Unity里就直接卡死，其实这是在socket accept时造成里阻塞，只要开启线程去accept就可以解决了

1. using UnityEngine;
   
2. using System.Collections;
   
3. using System.Net.Sockets;
   
4. using System.Net;
   
5. using System.Collections.Generic;
   
6. using System.Threading;
   
7. 
   
8. public class ServerSocket : MonoBehaviour {
   
9.     Socket tcpserver;
   
10.     static List<Client> clientList = new List<Client>();
    
11.     private string IP;
    
12.     // Use this for initialization
    
13.     void Start() {
    
14.         IP = GetLocalIp();
    
15.         print(IP);
    
16.         tcpServer = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    
17.         tcpServer.Bind(new IPEndPoint(IPAddress.Parse("192.168.1.120"), 7788));
    
18. 
    
19.         tcpServer.Listen(100);
    
20.     }
    
21.     static string GetLocalIp() {  //获取本机局域网IP
    
22.         string hostname = Dns.GetHostName();//得到本机名   
    
23.         IPHostEntry localhost = Dns.GetHostByName(hostname);//方法已过期，只得到IPv4的地址   
    
24.         //IPHostEntry localhost = Dns.GetHostEntry(hostname);  //可获取IPV6地址
    
25.         IPAddress localaddr = localhost.AddressList[0];
    
26.         return localaddr.ToString();
    
27.     }
    
28.     // Update is called once per frame
    
29.     void Update() {
    
30.         if (tcpServer != null) {
    
31.             Thread thread = new Thread(t => {
    
32.                 Socket clienttSocket = tcpServer.Accept();
    
33.                 Client client = new Client(clienttSocket);//把与每个客户端的逻辑放到client的对象里
    
34.                 clientList.Add(client);
    
35.             });
    
36.         }
    
37.     }
    
38. }

上面的Client是我声明了另一个类，用来存储客户端连接是的信息，

1. using UnityEngine;
   
2. using System.Collections;
   
3. using System.Net.Sockets;
   
4. using System.Net;
   
5. 
   
6. public class Client : MonoBehaviour {
   
7.     private Socket clientSocket;
   
8. 
   
9.     public Client(Socket s) {
   
10.         clientSocket = s;
    
11.     }
    
12. }
    
13. 
    
14. using引用了如下
    
15. using System.Net.Sockets;
    
16. using System.Net;
    
17. using System.Collections.Generic;
    
18. using System.Threading;
