python_udp_多人聊天室

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('\033[1;%sm %s:%s\033[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)
