Urllib2在python中的使用

Question

我试图使用用Python编写的爬虫来抓取网站，并希望将Tor与Python集成起来，这意味着我想使用Tor匿名地抓取网站。

我在堆积如山的地方找到了一些答案，但没有一个对我有用。

以下是我从Urllib2在python中使用Tor和socks中找到的第一个解决方案

import socks
import socket
import urllib2    
socks.setdefaultproxy(socks.PROXY_TYPE_HTTP, "127.0.0.1", 9050)
socket.socket = socks.socksocket
print urllib2.urlopen('http://my-ip.herokuapp.com').read()

但我得到的是错误

(501, 'Tor is not an HTTP Proxy')

然后，如何在urllib2中使用SOCKS 4/5代理？的公认答案

import socks
import socket
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, "127.0.0.1", 8080)
socket.socket = socks.socksocket
import urllib2
print urllib2.urlopen('http://www.google.com').read()

我得到了以下错误

<urlopen error [Errno 111] Connection refused>

然后，上面的投票结果来自TOR之上的Python urllib？

import socks
import socket
def create_connection(address, timeout=None, source_address=None):
    sock = socks.socksocket()
    sock.connect(address)
    return sock

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

# patch the socket module
socket.socket = socks.socksocket
socket.create_connection = create_connection

import urllib2

我的测试url是"http://almien.co.uk/m/tools/net/ip/"，上面的代码将运行2分钟，并以下面的错误结尾

  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])])
IndexError: tuple index out of range

有人评论说，最新的端口是9150，但9050，所以我再次尝试使用9150，得到以下错误

urllib2.URLError: <urlopen error [Errno 111] Connection refused>

更新

在我的机器上添加tor信息。

然后启动：

import socket
import urllib

import socks  # SocksiPy module
import stem.process

SOCKS_PORT = 9050

# Set socks proxy and wrap the urllib module

socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, '127.0.0.1', SOCKS_PORT)
socket.socket = socks.socksocket

# Perform DNS resolution through the socket

def getaddrinfo(*args):
  return [(socket.AF_INET, socket.SOCK_STREAM, 6, '', (args[0], args[1]))]

socket.getaddrinfo = getaddrinfo

print urllib.urlopen('http://my-ip.herokuapp.com').read()

基于喜爱代码使用stem。如果您也希望从python开始tor，则应该签出词干。
