1. 通过Gevent实现单线程下的多socket并发。
server 端：
#server side
import sys
import socket
import time
import gevent
from gevent import socket, monkey
monkey.patch_all()
def server(port):
s = socket.socket()
s.bind((‘0.0.0.0‘, port))
s.listen(500)
while True:
cli, addr = s.accept()
gevent.spawn(handle_request, cli) #只要过来一个请求，就起一个协程，把cli交给handle_request
def handle_request(conn):
try:
while True:
data = conn.recv(1024)
print("recv:", data)
conn.send(data)
if not data:
conn.shutdown(socket.SHUT_WR)
except Exception as ex:
print(ex)
finally:
conn.close()
if __name__ == ‘__main__‘:
server(8001)
Client 端：
import socket
HOST = ‘localhost‘ # The remote host
PORT = 8001 # The same port as used by the server
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
while True:
msg = bytes(input(">>:"), encoding="utf8")
s.sendall(msg)
data = s.recv(1024)
# print(data)
print(‘Received‘, repr(data)) #repr：格式化输出
s.close()
运行结果：实现了并发
