复制代码代码如下:

import os
import sys
import ftplib
class FTPSync(object):
def __init__(self):
self.conn = ftplib.FTP('10.22.33.46', 'user', 'pass')
self.conn.cwd('/') # 远端FTP目录
os.chdir('/data/') # 本地下载目录
def get_dirs_files(self):
u''' 得到当前目录和文件, 放入dir_res列表 '''
dir_res = []
self.conn.dir('.', dir_res.append)
files = [f.split(None, 8)[-1] for f in dir_res if f.startswith('-')]
dirs = [f.split(None, 8)[-1] for f in dir_res if f.startswith('d')]
return (files, dirs)
def walk(self, next_dir):
print 'Walking to', next_dir
self.conn.cwd(next_dir)
try:
os.mkdir(next_dir)
except OSError:
pass
os.chdir(next_dir)
ftp_curr_dir = self.conn.pwd()
local_curr_dir = os.getcwd()
files, dirs = self.get_dirs_files()
print "FILES: ", files
print "DIRS: ", dirs
for f in files:
print next_dir, ':', f
outf = open(f, 'wb')
try:
self.conn.retrbinary('RETR %s' % f, outf.write)
finally:
outf.close()
for d in dirs:
os.chdir(local_curr_dir)
self.conn.cwd(ftp_curr_dir)
self.walk(d)
def run(self):
self.walk('.')
def main():
f = FTPSync()
f.run()
if __name__ == '__main__':
