python 并发编程基于线程池实现并发的套接字通信

不应该让服务端随着并发的客户端数量增多，而无数起线程，应该用线程池，限制线程数量，控制最大并发数

io密集型程序，最大并发数是2

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:break
client.send(msg.encode("utf-8"))
data = client.recv(1024)
print(data.decode("utf-8"))client.close()

服务端

from socket import *
from concurrent.futures import ThreadPoolExecutordef communicate(conn):
''' 通信功能 '''
while True:
try:
data = conn.recv(1024)
if not data:break
conn.send(data.upper()) except ConnectionResetError:
break conn.close()def server(ip,port):
''' 负责建立连接 accept''' server = socket(AF_INET, SOCK_STREAM)
server.bind((ip,port))
server.listen(5) while True:
conn,addr = server.accept()
pool.submit(communicate,conn) server.close()if __name__ == "__main__":
pool = ThreadPoolExecutor(2)
server('127.0.0.1', 8080)
