python中协程实现TCP连接的代码示例

#服务端import socketfrom gevent import monkeyimport geventmonkey.patch_all()def handle_conn(seObj):    while True:        re_Data  = seObj.recv(1024).decode('utf-8')        if re_Data == 'quit':            break        print('client>>',re_Data)        value  = input("server>>")        se_Data = seObj.send(value.encode('utf-8'))        if se_Data == 'quit':            breakif __name__ == '__main__':    server = socket.socket()    server.bind(('192.168.1.227',9876))    print("服务已开启")    server.listen(4)    while True:        seObj,add = server.accept()        gevent.spawn(handle_conn,seObj)    seObj.close()    server.close()

import  socket# 1. 创建客户端的socket对象client = socket.socket()# 2. 连接服务端， 需要指定端口和IPclient.connect(('192.168.1.227',9876))while True:    # 3. 给服务端发送数据    send_data = input("client:>")    client.send(send_data.encode('utf-8'))    if send_data == 'quit':        break    # 4. 获取服务端返回的消息    recv_data = client.recv(1024).decode('utf-8')    if recv_data == 'quit':        break    print("server:>%s" %(recv_data))# 5. 关闭socket连接client.close()
