通过代理服务器访问FTP的Python代码

import urllib2
 
# Install proxy support for urllib2
proxy_info = { 'host' : 'proxy.myisp.com','port' : 3128,}
proxy_support = urllib2.ProxyHandler({"ftp" : "http://%(host)s:%(port)d" % proxy_info})
opener = urllib2.build_opener(proxy_support)
urllib2.install_opener(opener)
 
# List the content of a directory (it returns an HTML page built by the proxy)
# (You will have to parse the HTML to extract the list of files and directories.)
print urllib2.urlopen("ftp://login:[email?protected]/directory").read()
 
# Download a file:
data = urllib2.urlopen("ftp://login:[email?protected]/directory/myfile.zip").read()
open("myfile.zip","w+b").write(data)
