用于连接 FTP 并下载文件的 Python 2.5 脚本

问题描述

我确信这已经解决了，但我似乎找不到类似的问答(新手)使用 Windows XP 和 Python 2.5，我正在尝试使用脚本连接到 FTP 服务器并下载文件.它应该很简单，但是按照类似脚本的说明，我得到了错误:

I am sure this has been resolved before but I cannot seem to find a similar Q&A (newbie)Using Windows XP and Python 2.5, I m trying to use a script to connect to an FTP server and dowload files. It should be simple but following the instructions of similar scripts I get the errors:

ftp.login('USERNAME') File "C:Python25libftplib.py", line 373, in login if resp[0] == '3': resp = self.sendcmd('PASS ' + passwd) File "C:Python25libftplib.py", line 241, in sendcmd return self.getresp() File "C:Python25libftplib.py", line 216, in getresp raise error_perm, resperror_perm: 530 User USERNAME cannot log in.

我使用的脚本是:

def handleDownload(block): file.write(block) print ".",# Create an instance of the FTP object# FTP('hostname', 'username', 'password')ftp = FTP('servername')print 'ftplib example'# Log in to the serverprint 'Logging in.'# You can specify username and password here if you like:ftp.login('USERNAME', 'password') #print ftp.login()# This is the directory directory = '/GIS/test/data'# Change to that directory. print 'Changing to ' + directoryftp.cwd(directory)# Print the contents of the directoryftp.retrlines('LIST')

我很欣赏这可能是一个微不足道的问题，但如果有人能提供一些见解，那将非常有帮助！

I appreciate this might be a trivial question, but if anyone can provide some insights it would be very helpful!

谢谢，S

推荐答案

我不明白你用的是哪个库.Python 标准 urllib2 就足够了:

I can't understand which library are you using. Python standard urllib2 is sufficient:

import urllib2, shutilftpfile = urllib2.urlopen("ftp://host.example/path/to/file")localfile = open("/tmp/downloaded", "wb")shutil.copyfileobj(ftpfile, localfile)

如果您需要登录(匿名 登录是不够的)，请在 url 中指定凭据:

If you need to login (anonymous login isn't sufficient), then specify the credentials inside the url:

urllib2.urlopen("ftp://user:password@host.example/rest/of/the/url")
