基于Gevent的协程TCP并发实例,萌新学习笔记

# '''基于Gevent的协程TCP并发实例,可以同时处理几万连接量
import gevent
from gevent import monkey
monkey.patch_all() #接管所有阻塞
from socket import *

ADDR = ('0.0.0.0',8888)

s = socket()
s.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)
s.bind(ADDR)
s.listen(3)

def handle(c): # 循环收发客户端消息
    while True:
        data = c.recv(1024).decode()
        if not data:
            break
        print(data)
        c.send(b'OK')

while True:
    c,addr = s.accept() # 只阻塞在接收连接函数
    print('Connect from:',addr)
    gevent.spawn(handle,c)
