Python启动UDP服务,监听并接收客户端数据方式

[root@localhost python]# cat udp_server.py 
import socket

# 创建一个UDP socket
udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# 绑定到本地 IP 和端口
local_addr = ('192.168.6.211', 8888)
udp_socket.bind(local_addr)

print('UDP server is listening...')

while True:
    # 接收数据
    data, addr = udp_socket.recvfrom(1024)
    print(f'Received data from {addr}: {data.decode()}')

    # 回复数据
    reply = 'Received: ' + data.decode()
    udp_socket.sendto(reply.encode(), addr)

[root@localhost python]#

[root@localhost python]# cat udp_server.py 
import socket

# 创建一个UDP socket
udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# 发送数据
remote_addr = ('192.168.6.211', 8888)
udp_socket.sendto('Hello, UDP!'.encode(), remote_addr)

# 接收数据
data, addr = udp_socket.recvfrom(1024)
print(f'Received data from {addr}: {data.decode()}')

# 关闭 socket
udp_socket.close()
