Python FTPLIB错误530权限被拒绝

Question

我已经尝试了下面的脚本：

import os
from ftplib import FTP
ftp = FTP("ftpsite","myuser", "mypass")
ftp.login()
ftp.retrlines("LIST")
ftp.cwd("folderOne")
ftp.cwd("subFolder")
listing = []
ftp.retrlines("LIST", listing.append)
words = listing[0].split(None, 8)
filename = words[-1].lstrip()
#download the file
local_filename = os.path.join(r"C:example", file)
lf = open(local_filename, "wb")
ftp.retrbinary("RETR " + filename, lf.write, 8*1024)
lf.close()

但每次我运行脚本时，它都会说：

Traceback (most recent call last):
  File "C:UserDesktopsampleex.py", line 4, in <module>
    ftp = FTP("ftpsite", "myuser", "mypass")
  File "C:Python27libftplib.py", line 119, in __init__
    self.login(user, passwd, acct)
  File "C:Python27libftplib.py", line 387, in login
    resp = self.sendcmd('USER ' + user)
  File "C:Python27libftplib.py", line 244, in sendcmd
    return self.getresp()
  File "C:Python27libftplib.py", line 219, in getresp
    raise error_perm, resp
error_perm: 530 Permission denied.

我不知道530拒绝许可是什么意思。有人能告诉我这是什么意思吗？

• ftp服务器似乎允许匿名访问；您不需要传递用户名、密码
• FTP构造函数接受主机名（或IP），而不是URL

import sys
import os
from ftplib import FTP
ftp = FTP("ftpsite.com")
ftp.login()
ftp.cwd("/ftp/site/directory/")
listing = []
ftp.retrlines("LIST", listing.append)
words = listing[0].split(None, 8)
filesize = int(words[4])
filename = words[-1].lstrip()
class VerboseWriter:
    def __init__(self, lf, filesize):
        self.progress = 0
        self.lf = lf
        self.filesize = filesize
    def write(self, data):
        self.lf.write(data)
        self.progress += len(data)
        sys.stdout.write('r{}/{} ({:.1%})'.format(self.progress, self.filesize, float(self.progress)/self.filesize))
        sys.stdout.flush()
#download the file
with open(os.path.join(r"c:example", filename), 'wb') as f:
    ftp.retrbinary("RETR " + filename, VerboseWriter(lf, filesize).write, 8*1024)
print
ftp.quit()
