python ftp 按目录结构上传下载的实现代码

具体代码如下所示：

#!/usr/bin/python
# coding=utf-8
from ftplib import FTP
import time
import os
def __ftp_upload(ftp,local,remote,isDel=False):
  if os.path.isdir(local):
    for f in os.listdir(local):
      if os.path.isdir(local+f):
        try:
          ftp.cwd(remote+f)
        except:
          ftp.mkd(remote+f)
        print local+f
        __ftp_upload(ftp,local+f+'/',remote+f+'/',isDel)
      else:
        print remote+f
        print local+f
        fp = open(local+f, 'rb')
        ftp.storbinary('STOR ' + remote + f, fp, 4096)
        fp.close()
        if (isDel==True):
          os.remove(local)
  else:
    fp = open(local+f, 'rb')
    ftp.storbinary('STOR ' + remote + f, fp, 4096)
    fp.close()
    if (isDel==True):
      os.remove(local)
def ftp_upload(host,port,username,password,local,remote,isDel=False):
  ftp = FTP()
  try:
    ftp.connect(host,port)
    ftp.login(username,password)
  except:
    return False
  try:
    __ftp_upload(ftp,local,remote,False)
  except Exception,e:
    print e
  ftp.close()
  return True
def ftp_download(host,port,username,password,local,remote):
  ftp = FTP()
  ftp.connect(host,port)
  ftp.login(username,password)
  ret = False
  try:
    if os.path.isdir(local):
      for f in ftp.dir(remote):
        fp = open(local+f, 'wb')
        ftp.retrbinary('RETR ' + remote + f, fp.write, 4096)
        fp.close()
    else:
      fp = open(local, 'wb')
      ftp.retrbinary('RETR ' + remote, fp.write, 4096)
      fp.close()
    ret = True
  except Exception,e:
    print ("download exception:\n",e)
  ftp.close()
  return ret
if __name__=='__main__':
  host = '*.*.*.*'
  port = '21'
  username = 'xxx'
  password = 'xxx'
  ftp_upload(host,port,username,password,'/home/pi/work/xx/','/home/ubuntu/xx/',False)
  print 'download'
  ftp_download(host,port,username,password,'/home/pi/work/xx/hh.txt','/home/ubuntu/xx/hh.txt')

只完成了按目录结构上传，下载还没弄好。

补充：下面看下Python ftp 上传和下载

工具

python3
ftplib

上传

from ftplib import FTP
ftp = FTP(host='127.0.0.1', user='test', passwd='test') #创建
ftp.cwd('/home/test/ftp/') #上传路径
fd = open('test.txt', 'rb') #以只读的方式打开要上传的文件
ftp.storbinary('STOR test.txt', fd) #上传文件
fd.close()
ftp.quit() #退出登录
ftp.close() #关闭连接

下载

from ftplib import FTP
ftp = FTP(host='127.0.0.1', user='test', passwd='test') #创建
ftp.cwd('/home/test/ftp/') #服务器下载路径
fd = open('test.txt', 'wb') #以只写的方式打开要下载的文件
ftp.retrbinary('RETR test.txt', fd.write, 2048) #下载文件
fd.close()
ftp.quit() #退出登录
ftp.close() #关闭连接
