Python implementation of FTP loop upload files

In this article, the example for you to share the python implementation of FTP cycle upload file specific code, for your reference, the details are as follows

During testing, sometimes you will use the FTP data stream, or you need to use FTP to upload files repeatedly, so you write a python code for FTP cyclic file upload.

The code is as follows:

#coding=utf-8

import sys
import os
from ftplib import FTP
from time import sleep

_XFER_FILE = 'FILE'
_XFER_DIR = 'DIR'


class Transmitter(object): # Note: recursively upload local files or dirs to ftp server

  def __init__(self):
     = None

  def __del__(self):
    pass

  def setFtpParams(self, ip, uname, pwd, port=21, timeout=60):
     = ip
     = uname
     = pwd
     = port
     = timeout

  def initEnv(self):
    if  is None:
       = FTP()
      print('### Connecting to an FTP server: %s ...'' % )
      (, , )
      (, )

  def clearEnv(self):
    if :
      ()
      print('### Disconnect from FTP server: %s!' % )
       = None

  def uploadDir(self, localdir='./', remotedir='./'):
    if not (localdir):
      return
    (remotedir)
    for file in (localdir):
      src = (localdir, file)
      if (src):
        (src, file)
      elif (src):
        try:
          (file)
        except:
          ('Directory exists %s' % file)
        (src, file)
    ('..')

  def uploadFile(self, localpath, remotepath='./'):
    if not (localpath):
      return
    print('+++ upload %s to %s:%s' % (localpath, , remotepath))
    ('STOR ' + remotepath, open(localpath, 'rb'))
    sleep(0.5)
    try:
      (remotepath)
    except:
      pass
    # del file when uploaded this file
    # (localpath)
    # sleep(1)

  def __filetype(self, src):
    if (src):
      index = ('\\')
      if index == -1:
        index = ('/')
      return _XFER_FILE, src[index + 1:]
    elif (src):
      return _XFER_DIR, ''

  def upload(self, src):
    filetype, filename = self.__filetype(src)
    ()
    if filetype == _XFER_DIR:
       = src
      ()
    elif filetype == _XFER_FILE:
      (src, filename)
    ()


if __name__ == '__main__':
  srcDir = r'C:\Users\Administrator\Downloads\FTP\smp'
  transmitter = Transmitter()
  ('10.44.0.2', 'admin', '123123')

  while True:
    (srcDir)
    sleep(4)
