from ftplib import FTP
import logging
import os
import socket

logger = logging.getLogger("download")
logger.setLevel(logging.DEBUG)
fh = logging.FileHandler("download.log")
formatter = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")
fh.setFormatter(formatter)
logger.addHandler(fh)

def get_del():
    ip = '127.0.0.1'
    user_name = 'foo'
    passwd = 'bar'
    source_path = '/test_sour_dir/'
    try:
        ftp = FTP(ip)
        timeout=10 # in seconds
        socket.setdefaulttimeout(timeout)
        ftp.set_pasv(True)
        ftp.login(user_name, passwd)
        logger.info('login %s success' %(ip))
    except Exception, e:
        logger.error('Can\'t connect ftp server, %s' %(e))
        return
    try:
        ftp.cwd(source_path)
        remote_files = ftp.nlst()
    except Exception, e:

        return
    try:

            ftp.retrbinary('RETR %s' %(file_name), f.write, 4096)
            f.close()

        return
    ftp.close()
    return

if __name__ == "__main__":
