Use a Python socket to write an FTP-like script (only the download, upload and download almost no more write)

The introduction of the socket is not much to say, the internet can be searched, directly say the script, to achieve the function of FTP server and client,

Server-side:

Import socketserverimport commandsimport timeclass mysockserver ( Socketserver.baserequesthandler):     def handle (self):         print  "Got a new conn from", self.client_address         while True:             CMD = SELF.REQUEST.RECV (1024x768)              if not cmd:break             cmd = cmd.split ()              if cmd[0] == "Get":                 print  "Start transfer ..."                  with&nbsP;open (cmd[1], ' RB ')  as f:                     self.request.send (F.read ())                                   time.sleep (0.2)                  self.request.send ("OOK")     #这算是个标示吧. Client received this description has been passed                  continue            cmd_result =  Commands.getstatusoutput (cmd[0])    #执行客户端发地来的shell命令              self.request.send (cmd_result[1])              if __name__ ==  ' __main__ ':     host= '     port = 52167      s = socketserver.threadingtcpserver ((host,port),  MySockServer)      s.serve_forever ()      client: Import socketimport time host  =  ' x.x.x.x '   #服务器的地址port  = 52167addr = host,ports = socket.socket (Socket.af_inet,socket. SOCK_STREAM) s.connect (addr) while true:    input = raw_input (' Please  Your input: '). Strip ()     if len (input) ==0:continue    s.send (Input)     input = input.split ()     if Input[0]==  ' Get ':        print  ' get file           with open (input[1], ' WB ')  as f:     &Nbsp;      f.write (S.RECV (1024x768))          Time.sleep (0.2)         if s.recv (1024x768)  ==  "OOK":             print  "down finsh&nbsp ..."              continue       DATA = S.RECV (1024x768)     print data

I've been learning Python all the time, but it's always intermittent. Can't insist. Learn for a long time to write a simple socket, this IQ let people catch nasty ah.
