python-UDP聊天室测试

可以对比下tcp

服务端:


#udp测试
import socket
sk = socket.socket(type = socket.SOCK_DGRAM)
sk.bind(("127.0.0.1",10050))

# 收发
while 1:
    msg_str,addr = sk.recvfrom(1024)
    print("客户端:",msg_str.decode("utf-8"),addr)
    msg_s = input(">>>")
    sk.sendto(msg_s.encode("utf-8"),addr)
    if msg_s=='q':
        break

sk.close()


客户端:


import socket

sk = socket.socket(type=socket.SOCK_DGRAM)
#sk.connect(("127.0.0.1",10050))
while 1:
    msg_send = input("我:")
    sk.sendto(msg_send.encode('utf-8'),("127.0.0.1",10050))
    msg_r,addr = sk.recvfrom(1024)
    print("服务器:",msg_r.decode("utf-8"))
    if msg_r.decode("utf-8")=='q':
        break

sk.close()
