爬虫学习笔记–Tor隐藏Ip

因为在爬虫时，如果使用了默认的IP 可能导致自己的IP遭到封禁

所以就要隐藏自己的IP 

事先说明 爬虫要有度 也要考虑服务器的压力 

本篇基于win10 

tor的原理

1.安装tor浏览器

如果进不去网页 那么请自行解决 

2.tor的配置请看这篇

https://jingyan.baidu.com/article/adc815137654fbf723bf73b1.html

这样就可以搭建好了tor

python 要安装库

pip install pysocks

pip install stem

import socks
import socket
import requests

socks.set_default_proxy(socks.SOCKS5,"127.0.0.1",9150)
socket.socket = socks.socksocket

a = requests.get("http://checkip.amazonaws.com").text

print a

通过访问

http://checkip.amazonaws.com

会得到一个ip 会发现这个ip已经是隐藏的ip了 

controller.signal(Signal.NEWNYM)

切换ip

#coding=utf-8
from stem import Signal
from stem.control import Controller
import socket
import socks
import requests
import time
import sys
reload(sys)
sys.setdefaultencoding('utf-8')

controller = Controller.from_port(port=9151)
controller.authenticate()
socks.set_default_proxy(socks.SOCKS5,"127.0.0.1",9150)
socket.socket = socks.socksocket

total_scrappy_time = 0
total_changeIP_time = 0
for x in range(0,10):
    a = requests.get("http://checkip.amazonaws.com").text
    print ("第"+str(x+1)+"次IP："+a)

    time1 = time.time()
    a = requests.get("http://www.santostang.com/").text

    time2 = time.time()
    total_scrappy_time = total_scrappy_time + time2-time1
    print ("第"+str(x+1)+"次抓取花费时间："+str(time2-time1))

    time3 = time.time()
    controller.signal(Signal.NEWNYM)
    time.sleep(5)
    time4 = time.time()
    total_changeIP_time = total_changeIP_time + time4-time3-5
    print ("第"+str(x+1)+"次更换IP花费时间: "+str(time4-time3-5))

print ("平均抓取花费时间："+str(total_scrappy_time/10))
print ("平均更换IP时间："+str(total_changeIP_time/10))
