本文实例为大家分享了python实现FTP循环上传文件的具体代码，供大家参考，具体内容如下

测试过程中，有时会用到FTP的数据流，或者需要使用FTP反复上传文件，所以写了一个FTP循环上传文件的python代码。

代码如下：

#coding=utf-8

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

_XFER_FILE = 'FILE'
_XFER_DIR = 'DIR'


class Transmitter(object): # 注意:递归上传本地文件或dirs到ftp服务器

  def __init__(self):
    self.ftp = None

  def __del__(self):
    pass

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

  def initEnv(self):
    if self.ftp is None:
      self.ftp = FTP()
      print('### 连接FTP服务器: %s ...' % self.ip)
      self.ftp.connect(self.ip, self.port, self.timeout)
      self.ftp.login(self.uname, self.pwd)

  def clearEnv(self):
    if self.ftp:
      self.ftp.close()
      print('### 断开FTP服务器: %s!' % self.ip)
      self.ftp = None

  def uploadDir(self, localdir='./', remotedir='./'):
    if not os.path.isdir(localdir):
      return
    self.ftp.cwd(remotedir)
    for file in os.listdir(localdir):
      src = os.path.join(localdir, file)
      if os.path.isfile(src):
        self.uploadFile(src, file)
      elif os.path.isdir(src):
        try:
          self.ftp.mkd(file)
        except:
          sys.stderr.write('目录存在 %s' % file)
        self.uploadDir(src, file)
    self.ftp.cwd('..')

  def uploadFile(self, localpath, remotepath='./'):
    if not os.path.isfile(localpath):
      return
    print('+++ 上传 %s to %s:%s' % (localpath, self.ip, remotepath))
    self.ftp.storbinary('STOR ' + remotepath, open(localpath, 'rb'))
    sleep(0.5)
    try:
      self.ftp.delete(remotepath)
    except:
      pass
    # del file when uploaded this file
    # os.remove(localpath)
    # sleep(1)

  def __filetype(self, src):
    if os.path.isfile(src):
      index = src.rfind('\\')
      if index == -1:
        index = src.rfind('/')
      return _XFER_FILE, src[index + 1:]
    elif os.path.isdir(src):
      return _XFER_DIR, ''

  def upload(self, src):
    filetype, filename = self.__filetype(src)
    self.initEnv()
    if filetype == _XFER_DIR:
      self.srcDir = src
      self.uploadDir(self.srcDir)
    elif filetype == _XFER_FILE:
      self.uploadFile(src, filename)
    self.clearEnv()


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

  while True:
    transmitter.upload(srcDir)
    sleep(4)
