使用 TOR 运行 python 脚本

大家好！首先我想确保有类似的主题，但没有公认的答案或明确的回应。所以我想把它们结合起来再问一遍。我有以下脚本：

import urllib2

proxy = urllib2.ProxyHandler({"http":"127.0.0.1:9050"})
opener = urllib2.build_opener(proxy)
print(opener.open("http://www.ifconfig.me/ip").read())

我想匿名运行它，例如与 tor 一起使用。但它给出了这个错误：

Traceback (most recent call last):
  File "python_tor.py", line 5, in <module>
    print(opener.open("http://www.ifconfig.me/ip").read())
  File "/usr/lib/python2.7/urllib2.py", line 400, in open
    response = meth(req, response)
  File "/usr/lib/python2.7/urllib2.py", line 513, in http_response
    'http', request, response, code, msg, hdrs)
  File "/usr/lib/python2.7/urllib2.py", line 438, in error
    return self._call_chain(*args)
  File "/usr/lib/python2.7/urllib2.py", line 372, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.7/urllib2.py", line 521, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 501: Tor is not an HTTP Proxy

我在 stackoverflow 中找到了以下答案：

 proxy_support = urllib2.ProxyHandler({"http" : "127.0.0.1:8118"})
    opener = urllib2.build_opener(proxy_support) 
    opener.addheaders = [('User-agent', 'Mozilla/5.0')]
    print opener.open('http://www.google.com').read()

还有这个主题的评论：

It may be worthwhile for people reading this thread to know that port 8118 is actually Privoxy's port, not Tor. Tor is a strictly SOCKS-only proxy (port 9050) so it rejects all non-SOCKS traffic (e.g. HTTP). To handle non-SOCKS traffic, you would need to use Privoxy (port 8118) or Polipo (port 8123) to translate the traffic into SOCKS so Tor would accept.

Privoxy is better for privacy and Polipo is better for performance because it does caching.

谁能解释如何匿名执行我的脚本？

使用给出的答案是可能的：

import socks
import socket
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, "127.0.0.1", 9050)
socket.socket = socks.socksocket
import urllib2

print(urllib2.urlopen("http://www.ifconfig.me/ip").read())

但我很惊讶是否可以根据每个新请求更改tor的IP地址？？？
