Python中的多线程UDP服务器

Question

我正在尝试用Python构建一个多线程UDP服务器，它如下所示：

import socket
import threading 


class udpreceive:
    def __init__(self, port, ip):
        self.port = port
        self.ip = ip
        self.sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    def start(self):
        while True:
            data, addr = self.sock.recvfrom(2048)
            print(data)

s1 = udpreceive(514, "192.168.1.5")
s2 = udpreceive(515, "192.168.1.5")
threads = [threading.Thread(target=s1.start), threading.Thread(target=s2.start)]

for th in threads:
     th.start()
     print(f'threads {th} started')
     th.join(0.1)

我得到这个错误： data, addr = self.sock.recvfrom(2048) OSError: [WinError 10022] An invalid argument was supplied

有什么问题吗？我已经坚持了好几个小时了

这是客户端：

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
counter = 0
while True:
    send_data = "Client number" + str(counter)
    s.sendto(send_data.encode(), ('127.0.0.1', 777))
    print(send_data)
    counter += 1
