Question

我试图连接到ftp代理后面的ftp服务器。代理服务器不需要用户名和密码，ftp服务器也需要。我搜索过几个帖子：

这是我的代码的最后一个版本。到目前为止，我已经想到要在ftp代理后面打开ftp服务器，可以使用符号ftp://username:password@server。我正在使用urllib2库来定义代理服务器。

import urllib2

proxy_host = '101.11.44.84:8021'  # only host name, no scheme (http/ftp)
proxy_handler = urllib2.ProxyHandler({'ftp': proxy_host}) 
auth = urllib2.FTPHandler()
try:
    opener_thru_proxy = urllib2.build_opener(proxy_handler, auth)
except:
    logger.exception('build_opener error')    
    raise
print opener_thru_proxy
try:
    conn = opener_thru_proxy.open('ftp://user:password@100.159.66.113')
except:
    logger.exception('opener thru proxy error')
    raise
print conn.read()
conn.close()

此代码的输出产生：

似乎我无法与ftp服务器建立ftp连接。但是，当我使用相同的连接数据集并在Total Commander中使用它时，连接正常。请参阅随附的图像Total Commander ftp connection window。

使用Python脚本在FTP代理后面建立FTP连接
