UDP 简易聊天室

import socket

# 1、使用UDP协议实现，A用户给B用户发送消息，B用户负责将A发送的消息放到文本日志里

# 1、创建udp套接字
from threading import Thread

socket_client = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# 绑定ip
socket_client.bind(("127.0.0.1", 7788))


# 2、发送数据
def send():
    try:
        while True:
            msg = input("发送的数据为：")
            socket_client.sendto(msg.encode("utf-8"), ("127.0.0.1", 8888))
            if msg == "88":
                break
    except:
        print("聊天室关闭")
    finally:
        socket_client.close()


def receive():
    try:
        while True:
            # 3.接收数据：
            c_msg, ip = socket_client.recvfrom(512)
            # 4、打印数据
            print(f"{ip}发送的数据：{c_msg.decode('utf-8')}")
    except:
        print("聊天室关闭")
    finally:
        socket_client.close()
