Tor 的 Python 脚本异常

Question

我有以下使用 SocksiPY 的脚本

和 Tor:

from TorCtl import TorCtl

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

import urllib2
import sqlite3
from BeautifulSoup import BeautifulSoup

def newId():
    conn = TorCtl.connect(controlAddr="127.0.0.1", controlPort=9051, passphrase="123")
    TorCtl.Connection.send_signal(conn, "NEWNYM")

newId()

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

此代码应更改 Tor 身份，但它会等待一段时间并出现以下错误:

tuple index out of range
Traceback (most recent call last):
  File "template.py", line 16, in <module>
    newId()
  File "template.py", line 14, in newId
    TorCtl.Connection.send_signal(conn, "NEWNYM")
TypeError: unbound method send_signal() must be called with Connection instance as first argument (got NoneType instance instead)

但上面的脚本分为2个独立的脚本:

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

import urllib2
import sqlite3
from BeautifulSoup import BeautifulSoup

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

和:

from TorCtl import TorCtl
def newId():
    conn = TorCtl.connect(controlAddr="127.0.0.1", controlPort=9051, passphrase="123")
    TorCtl.Connection.send_signal(conn, "NEWNYM")

newId()

当调用第二个脚本然后调用第一个脚本时就可以了。谁能解释问题是什么以及如何解决？

Anonymous 很好地解释了这个套接字覆盖，答案几乎是完美的，除了你必须关闭控制套接字。由于 TorCtl 事件循环，它更安全，但我必须深入研究 TorCtl 代码才能理解这个事件循环。

总结你的代码变成:

from TorCtl import TorCtl

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

import urllib2
import sqlite3
from BeautifulSoup import BeautifulSoup

__originalSocket = socket.socket

def newId():
    ''' Clean circuit switcher

    Restores socket to original system value.
    Calls TOR control socket and closes it
    Replaces system socket with socksified socket
    '''
    socket.socket = __originalSocket
    conn = TorCtl.connect(controlAddr="127.0.0.1", controlPort=9051, passphrase="123")
    TorCtl.Connection.send_signal(conn, "NEWNYM")
    conn.close()
    socket.socket = socks.socksocket

newId()

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