协程下的socket并发

服务端

from gevent import monkey;monkey.patch_all()
from socket import *
import gevent

def server(server_ip,port):
    s=socket(AF_INET,SOCK_STREAM)
    s.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)
    s.bind((server_ip,port))
    s.listen(5)
    while True:
        conn,addr=s.accept()
        # 生成一个协程
        gevent.spawn(talk,conn,addr)

def talk(conn,addr):
    try:
        while True:
            res=conn.recv(1024)
            print('client %s:%s msg: %s' %(addr[0],addr[1],res))
            conn.send(res.upper())
    except Exception as e:
        print(e)
    finally:
        conn.close()

if __name__ == '__main__':
    server('127.0.0.1',8080)

客户端

from socket import *

client=socket(AF_INET,SOCK_STREAM)
client.connect(('127.0.0.1',8080))


while True:
    msg=input('>>: ').strip()
    if not msg:continue

    client.send(msg.encode('utf-8'))
    msg=client.recv(1024)
    print(msg.decode('utf-8'))
