gevent 实现单线程下的socket链接

通过gevent实现socket的多并发

server 端：

import geventfrom gevent import socket, monkey

monkey.patch_all()   #进行IO标记

def server(port):    s = socket.socket()    s.bind((‘localhost‘, port))    s.listen()    while True:        conn, addr = s.accept()        gevent.spawn(handle, conn) #一接收信号就进行IO切换

def handle(conn):    try:      data = conn.recv(1024)      print(data)      conn.send(data)      if not data:          conn.shutdown(socket.SHUT_WR) #如果没有数据就关掉socket    except exception as ex:        print(ex)    finally:        conn.close()

if __name__==‘__main__‘:    server(8000)

client 端：

import socket, time

client = socket.socket()client.connect((‘localhost‘, 6000))while True:    data = input(‘>>‘)    client.send(data.encode(‘utf-8‘))    if not data:        break

d = client.recv(1024)    print(‘recv:‘, d.decode())
