问题
I'm trying to access *.onion sites using python. Didn't success yet, though.
I've read a lot of stackoverflow questions&answers, tried a lot of different ways of resolving this problem: I tried using Python 2.7 and Python 3.5, tried using urllib, urllib2, requests (then I found out requests doesn't work with socks), pysocks, etc, but nothing seems to work.
Right now I'm at the point where I only get the following Error:
> <urlopen error [Errno 11001] getaddrinfo failed>
No, I don't have a firewall, and yes, I have a good internet connection, and yes, the site does exist. I think the problem is that it's an *.onion link.
This is what I'm doing right now:
import socks
import socket
import urllib
import urllib.request
socks.set_default_proxy(socks.SOCKS5, "127.0.0.1", 9050)
socket.socket = socks.socksocket
r = urllib.request.urlopen("http://xmh57jrzrnw6insl.onion")
r.read()
and this is what I'm getting:

I'm very new to all this stuff, so I might be missing some really simple parts. But I'll be grateful for any help.
ps: when trying to access not an *.onion site, I get the following:
[WinError 10061] No connection could be made because the target machine actively refused it
回答1:
I'm on Linux but the code you supplied didn't work for me. From the looks of it the DNS resolution is not happening over Tor (based on error 11001 WSAHOST_NOT_FOUND). I'm a little suspicious that it's actually using Tor because of the 10061 (connection refused) error too.
In any case, I was able to get it working with this:
import urllib2
import socks
from sockshandler import SocksiPyHandler
opener = urllib2.build_opener(SocksiPyHandler(socks.SOCKS5, "127.0.0.1", 9050, True))
print opener.open("http://xmh57jrzrnw6insl.onion").read()
PySocks says in their docs:
Note that monkeypatching may not work for all standard modules or for all third party modules, and generally isn't recommended. Monkeypatching is usually an anti-pattern in Python.
The monkey patching is the use of socket.socket = socks.socksocket.
If possible, use Requests with the socks5h:// protocol handlers for your proxies:
import requests
import json
proxies = {
'http': 'socks5h://127.0.0.1:9050',
'https': 'socks5h://127.0.0.1:9050'
}
data = requests.get("http://xmh57jrzrnw6insl.onion",proxies=proxies).text
print(data)
