python 进程、线程、协程感悟

进程：

感觉只是使用Process模块加以使用即可：

# -*- coding: utf-8 -*-
# data:2019-02-23 21:23
# user:DIY
# file:thread_master.py
from socket import *
from multiprocessing import Process
from  time import sleep
def dealWithClient(newSocket,destAddr):
    while True:
        recvData = newSocket.recv(1024)
        if recvData:
            print('recv[%s]:[%s]' %(str(destAddr),recvData.decode()))
        else:
            print('[%s]客户端已经关闭'%(str(destAddr)))
            break
    newSocket.close()
def main():
    serSocket = socket(AF_INET,SOCK_STREAM)
    serSocket.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)
    localAddr = ('',7788)
    serSocket.bind(localAddr)
    serSocket.listen(5)
    try:
        while True:
            print('----主进程等待新客户端的到来---')
            newSocket,destAddr = serSocket.accept()
            print('---主进程接来下创建一个新的进程负责数据处理数据[%s]' %str(destAddr))
            client = Process(target=dealWithClient,args=(newSocket,destAddr))
            client.start()
            newSocket.close()
    finally:
        serSocket.close()
if __name__ == '__main__':
    main()

　线程感觉只是使用Thread模块加以使用即可：

# -*- coding: utf-8 -*-
# data:2019-02-24 7:47
# user:DIY
# file:Thread_master.py
from socket import *
from threading import Thread
from  time import sleep
def dealWithClient(newSocket,destAddr):
    while True:
        recvData = newSocket.recv(1024)
        if recvData:
            print('recv[%s]:[%s]' %(str(destAddr),recvData.decode()))
        else:
            print('[%s]客户端已经关闭'%(str(destAddr)))
            break
    newSocket.close()
def main():
    serSocket = socket(AF_INET,SOCK_STREAM)
    serSocket.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)
    localAddr = ('',7788)
    serSocket.bind(localAddr)
    serSocket.listen(5)
    try:
        while True:
            print('----主进程等待新客户端的到来---')
            newSocket,destAddr = serSocket.accept()
            print('---主进程接来下创建一个新的进程负责数据处理数据[%s]' %str(destAddr))
            client = Thread(target=dealWithClient,args=(newSocket,destAddr))
            client.start()
            # newSocket.close()
    finally:
        serSocket.close()
if __name__ == '__main__':
    main()

　协程感觉只是使用monkey和gevent模块加以使用即可：

# -*- coding: utf-8 -*-
# data:2019-02-24 9:13
# user:DIY
# file:yield_协程.py
import sys,time,gevent
from gevent import socket,monkey
 
monkey.patch_all()
def handel_request(conn):
    while True:
        data = conn.recv(1024)
        time.sleep(5)
        if not data:
            print('[%s]连接断开' % conn)
            conn.close()
            break
        print('recv',data.decode())
def server(port):
    s = socket.socket()
    s.bind(('127.0.0.1',port))
    s.listen(5)
    while True:
        cli,add = s.accept()
        gevent.spawn(handel_request,cli)
 
if __name__ == '__main__':
    server(8080)
