Python实现FTP上传文件或文件夹实例（递归）

本文实例讲述了Python实现FTP上传文件或文件夹实例。分享给大家供大家参考。具体如下：

import sys
import os
import json
from ftplib import FTP 

_XFER_FILE = 'FILE'
_XFER_DIR = 'DIR' 

class Xfer(object):
  '''''
  @note: upload local file or dirs recursively to ftp server
  '''
  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 '### connect ftp server: %s ...'%self.ip
      self.ftp.connect(self.ip, self.port, self.timeout)
      self.ftp.login(self.uname, self.pwd)
      print self.ftp.getwelcome() 

  def clearEnv(self):
    if self.ftp:
      self.ftp.close()
      print '### disconnect ftp server: %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('the dir is exists %s'%file)
        self.uploadDir(src, file)
    self.ftp.cwd('..') 

  def uploadFile(self, localpath, remotepath='./'):
    if not os.path.isfile(localpath):
      return
    print '+++ upload %s to %s:%s'%(localpath, self.ip, remotepath)
    self.ftp.storbinary('STOR ' + remotepath, open(localpath, 'rb')) 

  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:\sytst"
  srcFile = r'C:\sytst\sar.c'
  xfer = Xfer()
  xfer.setFtpParams('192.x.x.x', 'jenkins', 'pass')
  xfer.upload(srcDir)
  xfer.upload(srcFile)
