python_udp_多人聊天室_简单版

udp-一定是client端先发送数据。

server.py

import socket
friend_lst = {'alex':'32','太白':'33'}
sk =socket.socket(type=socket.SOCK_DGRAM)
sk.bind(('127.0.0.1',9001))
while True:
    msg,addr = sk.recvfrom(1500)
    msg = msg.decode('utf-8')
    name,message  = msg.split('|',1)
    print('33[1;%sm %s:%s33[0m'%(friend_lst.get(name,'30'),name,message))
    content = input('>>>')
    sk.sendto(content.encode('utf-8'),addr)


# 补充知识：
# 1-字典的 dic.get(k,default_v)=v 方法: 如果k在字典中存在就返回它对应的v,如果不存在就返回一个设置的默认的default_v
# 2-print的字符串的颜色：EVA的微博

client_1.py

import socket
name = '太白'
# name = '大壮'
sk = socket.socket(type=socket.SOCK_DGRAM)

while True:
    content = input('>>>')
    if content.upper() == 'Q':
        break
    content = '%s|%s'%(name,content)
    sk.sendto(content.encode('utf-8'),('127.0.0.1',9001))
    msg = sk.recv(1024).decode('utf-8')
    if msg.upper() == 'Q':
        break
    print(msg)

client_2.py

import socket
name = 'alex'
sk = socket.socket(type=socket.SOCK_DGRAM)

while True:
    content = input('>>>')
    if content.upper() == 'Q': break
    content = '%s|%s'%(name,content)
    sk.sendto(content.encode('utf-8'),('127.0.0.1',9001))
    msg = sk.recv(1024).decode('utf-8')
    if msg.upper() == 'Q': break
    print(msg)
