套接字通信统一时的错误避免

Question

我正在尝试接收与C# on Unity的套接字通信。

如果中断unityRecieve.cs，下面的Send.py将导致错误。

Send.py

import socket
import random

    HOST = '127.0.0.1'
    PORT = 50007

    client = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    while True:
　　a = random.randrange(3)
　　result = str(a)
　　print(a)
　　client.sendto(result.encode('utf-8'),(HOST,PORT))
　　time.sleep(2.0)

unityRecieve.cs

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

public class unityRecieve : MonoBehaviour
{

    static UdpClient udp;

    void Start()
    {
        int LOCA_LPORT = 50007;

        udp = new UdpClient(LOCA_LPORT);
        udp.Client.ReceiveTimeout = 100;
    }

    void Update()
    {
        IPEndPoint remoteEP = null;
        byte[] data = udp.Receive(ref remoteEP);
        string text = Encoding.UTF8.GetString(data);
        Debug.Log(text);
    }
}

当unitiRecieve.cs被中断时，我如何使Send.py继续运行而不给出错误消息？

不确定是否考虑过异常处理。如果你不这样做，这可能会给你指明正确的方向。
