Python并发编程-多进程socketserver简易版

普通版的socketserver

#server.py

import socket

sk = socket.socket()
sk.bind(('127.0.0.1',8080))#建立连接
sk.listen() #打开监听
while True:
    conn,addr = sk.accept() #接收到一个连接和一个地址
    ret = 'hi'.encode('utf-8')
    conn.send(ret)
    msg = conn.recv(1024).decode('utf-8')
    print(msg)
    conn.close()
sk.close()

#Client.py
import socket

sk = socket.socket()
sk.connect(('127.0.0.1',8080))

msg = sk.recv(1024).decode('utf-8')
print(msg)
msg2 = input('>>>').encode('utf-8')
sk.send(msg2)

sk.close()

简易多进程socketserver

###server.py
import socket
from multiprocessing import Process
#主要的不同是利用了函数和子进程,这里建立了函数
def serve(conn):
    ret = 'hi'.encode('utf-8')
    conn.send(ret)
    msg = conn.recv(1024).decode('utf-8')
    print(msg)
    conn.close()

if __name__ == '__main__':
    sk = socket.socket()
    sk.bind(('127.0.0.1',8080))#建立连接
    sk.listen() #打开监听
    while True:
        conn,addr = sk.accept() #接收到一个连接和一个地址
#开启子进程
        p = Process(target=serve,args =(conn,))
        p.start()
    sk.close()

###client.py
import socket

sk = socket.socket()
sk.connect(('127.0.0.1',8080))

msg = sk.recv(1024).decode('utf-8')
print(msg)
msg2 = input('>>>').encode('utf-8')
sk.send(msg2)

sk.close()
