本文實例講述了Python實現FTP上傳文件或文件夾實例。分享給大家供大家參考。具體如下：

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)
