在使用tor代理时如何控制tor

Question

我试图用tor连接到一个资源，改变身份。但是，在第一次连接试图更改标识后，会导致错误。代码：

import urllib2, socks, socket
from stem import Signal
from stem.control import Controller


def newI():
    with Controller.from_port(port=9051) as controller:
        controller.authenticate()
        controller.signal(Signal.NEWNYM)

newI()

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

headers = {'User-Agent': 'Mozilla/3.0 (x86 [en] Windows NT 5.1; Sun)'} 
req = urllib2.Request('https://google.com', None, headers)
response = urllib2.urlopen(req)
html = response.read()

newI()

我得到了错误：

  File "/media/all/Run/e/c.py", line 21, in <module>
    newI()
  File "/media/all/Run/e/c.py", line 7, in newI
    with Controller.from_port(port=9051) as controller:
  File "/usr/local/lib/python2.7/dist-packages/stem/control.py", line 659, in from_port
    control_port = stem.socket.ControlPort(address, port)
  File "/usr/local/lib/python2.7/dist-packages/stem/socket.py", line 314, in __init__
    self.connect()
  File "/usr/local/lib/python2.7/dist-packages/stem/socket.py", line 187, in connect
    self._socket = self._make_socket()
  File "/usr/local/lib/python2.7/dist-packages/stem/socket.py", line 340, in _make_socket
    control_socket.connect((self._control_addr, self._control_port))
  File "/usr/lib/python2.7/dist-packages/socks.py", line 369, in connect
    self.__negotiatesocks5(destpair[0],destpair[1])
  File "/usr/lib/python2.7/dist-packages/socks.py", line 236, in __negotiatesocks5
    raise Socks5Error(ord(resp[1]),_generalerrors[ord(resp[1])])
TypeError: __init__() takes exactly 2 arguments (3 given)

也许我需要禁用代理。告诉我怎么做正确。

UPD：

它的工作是：

import pycurl
import cStringIO
from stem import Signal
from stem.control import Controller


def newI():
    with Controller.from_port(port=9051) as controller:
        controller.authenticate()
        controller.signal(Signal.NEWNYM)

newI()

buf = cStringIO.StringIO()
c = pycurl.Curl()
c.setopt(pycurl.URL, 'http://google.com/')
c.setopt(c.WRITEFUNCTION, buf.write)
c.setopt(pycurl.PROXY, 'localhost')
c.setopt(pycurl.PROXYPORT, 9050)
c.setopt(pycurl.PROXYTYPE, pycurl.PROXYTYPE_SOCKS5)
c.perform()
html = buf.getvalue()[7:]
buf.close()

newI()

Answer 1

这个问题是由socket.socket = socks.socksocket行引起的。

作为一种临时解决方案，您可以保留socket.socket的备份副本，并在向Tor请求新身份之前使用该副本取消代理设置，然后再次设置代理。

代码将如下所示：

import urllib2, socks, socket
from stem import Signal
from stem.control import Controller

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

def newI():
    socket.socket = old_socket  # don't use proxy
    with Controller.from_port(port=9051) as controller:
        controller.authenticate()
        controller.signal(Signal.NEWNYM)
    # set up the proxy again
    socket.socket = socks.socksocket

newI()

headers = {'User-Agent': 'Mozilla/3.0 (x86 [en] Windows NT 5.1; Sun)'} 
req = urllib2.Request('https://google.com', None, headers)
response = urllib2.urlopen(req)
html = response.read()

newI()

但是，我仍然在等待有人发布关于错误发生的原因的解释，以及修复错误的更好方法。

有意思的。我想知道是否..。

socket.socket = socks.socksocket

导致_make_socket()获得一个非标准的套接字，进而导致批量。如果你用PycURL代替，它能工作吗？
