Python implements FTP to upload files in a loop

The examples in this article share the specific code of python to realize FTP uploading files for your reference. The specific content is as follows

During the test, sometimes the FTP data stream is used, or it is necessary to use FTP to upload files repeatedly, so I wrote a python code for FTP to upload files in a loop.

code show as below:

# coding=utf-8import sys
import os
from ftplib import FTP
from time import sleep

_ XFER_FILE ='FILE'
_ XFER_DIR ='DIR'classTransmitter(object): #note:Recursively upload local files or dirs 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 to FTP server: %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('###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('Directory exists%s'% file)
  self.uploadDir(src, file)
 self.ftp.cwd('..')

 def uploadFile(self, localpath, remotepath='./'):if not os.path.isfile(localpath):returnprint('+++Upload%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)

The above is the whole content of this article, I hope it will be helpful to everyone's study.
