Bir proýektim üçin ftp://ftp.ucar.edu/mesouser saýty mirror etmel
boldum. Köp ftp program-leri ulanyp gördüm. Birisi hem
universitynyň proxy-serveri bilen öňuşup bilmedi. Bu ýerde FTP
porti baglagyly eken. Näme etmlei bor?

Birini özim ýazdym :) Python-da ftplib hem proxy-server bilen öňuşup bilmedi. urllib2-dan
ulandym, netijeler HTML suratda geldi :( . Aý näme bolsa HTML bilen
oňuşmaly boldym.

bu hem ftpmirror ködi: (LISENSE: GPL2 :)

url = 'ftp://ftp.ucar.edu/mesouser/'
localdir = 'mm5'
proxy = '192.168.50.50:2323'

proxy_password = 'hummmmmm!'


import os

import urllib2

def get_ftp(url, the_dir):
  if not os.path.exists(the_dir):
    os.mkdir(the_dir)
  os.chdir(the_dir)
  print 'CD %s' % the_dir

  req = urllib2.Request(url)
  data = urllib2.urlopen(req).read()
  lines = data.split('\n')
  items = [(line.split('"')[1], line.find('DIR') > -1)
           for line in lines if re.search(r'(FILE|DIR)', line)
           is not None]

  for link, is_dir in items:
    the_url = urlparse.urljoin(url,link)
    the_path = os.path.abspath(link)
    if is_dir:
      if link != '../': get_ftp(the_url, the_path)
    else:
      print 'GET %s' % the_url
      req = urllib2.Request(the_url)
      data = urllib2.urlopen(req).read()
      fp = file(the_path, 'wb')
      fp.write(data)
      fp.close()
    os.chdir(the_dir)

proxy_handler = urllib2.ProxyHandler(
  {'ftp': 'http://%s:%s@%s' % (proxy_user, proxy_password, proxy)}
)

opener= urllib2.build_opener(proxy_handler)

urllib2.install_opener(opener)

get_ftp (url, os.path.abspath(localdir))
