开发socketserver 以及定制开发自己的FTP服务器

socket server 示例

#服务端程序
import socketserver

class  TcpHandler(socketserver.BaseRequestHandler):
    def handle(self):
        while True:
            try:
                self.data = self.request.recv().strip()
                print(self.client_address[])
                print(self.data)
                self.request.send(self.data.upper())
            except ConnectionResetError as e:
                print("连接断开")
                break

if __name__ =="__main__":
    HOST,PORT ="localhost",
    server = socketserver.ThreadingTCPServer((HOST,PORT),TcpHandler)
    server.serve_forever()
