用Python实现点对点的聊天，2个程序，一个是client.py，一个是server.py，通过本机地址127.0.0.1连接进行通信，利用多线程把发送消息和接收消息分开独立进行。

client代码：

import socket

import sys

import threading

import time

class client():

def __init__(self):

self.s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

self.ip = "127.0.0.1"

def connect(self):

try:

self.s.connect((self.ip,8888))

print("connect success")

print('connect time: '+time.ctime())

except ConnectionError:

print('connect error')

sys.exit(-1)

except:

print('unexpect error')

sys.exit(-1)

def send_sth(self):

while True:

sth=input('say something:n')

try:

self.s.sendall(sth.encode('utf-8'))

except ConnectionError:

print('connect error')

sys.exit(-1)

except:

print('unexpect error')

sys.exit(-1)

def receive(self):

while True:

try:

r=self.s.recv(1024)

print ('get message:'+r.decode('utf-8'))

except ConnectionError:

print('connect error')

sys.exit(-1)

except:

print('unexpect error')

sys.exit(-1)

c1 = client()

c1.connect()

threading._start_new_thread(c1.receive,())

c1.send_sth()

server代码：

import socket

import sys

import threading

import time

def server():

def bind():

HOST='127.0.0.1'

s.bind((HOST,8888))

print("bind ok")

def listen():

s.listen(10)

print ('Socket now listening')

def send_sth(conn):

while True:

try:

sth=input('say something:n')

conn.sendall(sth.encode('utf-8'))

except ConnectionError:

print('connect error')

sys.exit(-1)

except:

print('unexpect error')

sys.exit(-1)

def recv(conn):

while True:

try:

data=conn.recv(1024)

data2=data.decode('utf-8')

print('get message:'+data2)

except ConnectionError:

print('connect error')

sys.exit(-1)

except:

print('unexpect error')

sys.exit(-1)

s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)

bind()

listen()

conn,addr=s.accept()

print("connect success")

print('connect time: '+time.ctime())

threading._start_new_thread(recv,(conn,))

send_sth(conn)

if __name__=='__main__':

server()

开启多线程有2种方法，上面2个程序都是用函数的方法，还有一种方法是用类继承threading类

代码：

import socket

import threading

class client(threading.Thread):

def __init__(self,sth):

threading.Thread.__init__(self)

self.sth=sth

def run(self):

s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)

ip="127.0.0.1"

try:

s.connect((ip,8888))

except :

print('con error')

exit()

#print("connect success")

s.sendall(self.sth.encode('utf-8'))

#print("send success")

try:

r=s.recv(1024)

except:

print('recv error')

exit()

print (r.decode('utf-8'))

c1=client('hello 1')

c1.start()

c2=client('hello 2')

c2.start()
