socketserver多进程服务器：
    并发处理多个客户请求
    使用方法：
        1，创建类，必须继承
        2，handle方法
        3，server.serve_forever()

import socket,socketserver

class myserver(socketserver.BaseRequestHandler):
    def handle(self):

        conn = self.request
        conn.sendall(bytes('hello',encoding='utf-8'))
        ret = conn.recv(1024)
        ret_str = str(ret,encoding='utf-8')
        print(ret_str)

if __name__ == '__main__':
    server = socketserver.ThreadingTCPServer(('127.0.0.1',9999),myserver)
    server.serve_forever()
