爬取西刺代理的IP与端口（一）

0x01 简陋代码是，获取(.*?)的字符串

#coding:utf-8

from requests import *
import re

headers = { "accept":"text/html,application/xhtml+xml,application/xml;",
            "accept-encoding":"gzip",
            "accept-language":"zh-cn,zh;q=0.8",
            "referer":"Mozilla/5.0(compatible;Baiduspider/2.0;+http://www.baidu.com/search/spider.html)",
            "connection":"keep-alive",
            "user-agent":"mozilla/5.0(windows NT 6.1;wow64) applewebkit/537.36 (khtml,like gecko)chrome/42.0.2311.90 safari/537.36"
            }
url="https://www.xicidaili.com/wn/"
html=get(url,timeout=3,headers=headers).text

iplist = re.findall('<td>(.*?)</td>',html)
print(iplist)

0x02 只爬取IP与端口，findall带两个(.*?)，则两个为一组

#coding:utf-8

from requests import *
import re

headers = { "accept":"text/html,application/xhtml+xml,application/xml;",
            "accept-encoding":"gzip",
            "accept-language":"zh-cn,zh;q=0.8",
            "referer":"Mozilla/5.0(compatible;Baiduspider/2.0;+http://www.baidu.com/search/spider.html)",
            "connection":"keep-alive",
            "user-agent":"mozilla/5.0(windows NT 6.1;wow64) applewebkit/537.36 (khtml,like gecko)chrome/42.0.2311.90 safari/537.36"
            }
url="https://www.xicidaili.com/wn/"
html=get(url,timeout=3,headers=headers).text

pattern = re.compile('<tr class=".*?">.*?<td.*?</td>.*?<td>(.*?)</td>.*?<td>(.*?)</td>.*?</tr>', re.S)
iplist = re.findall(pattern,html)
print(iplist)

这样就简单多了，直接for循环把每个元组提取出来，且元组支持切片，[0]获取每个ip，[1]获取每个端口

0x03 最终输出格式如下

#coding:utf-8

from requests import *
import re

headers = { "accept":"text/html,application/xhtml+xml,application/xml;",
            "accept-encoding":"gzip",
            "accept-language":"zh-cn,zh;q=0.8",
            "referer":"Mozilla/5.0(compatible;Baiduspider/2.0;+http://www.baidu.com/search/spider.html)",
            "connection":"keep-alive",
            "user-agent":"mozilla/5.0(windows NT 6.1;wow64) applewebkit/537.36 (khtml,like gecko)chrome/42.0.2311.90 safari/537.36"
            }
url="https://www.xicidaili.com/wn/"
html=get(url,timeout=3,headers=headers).text

pattern = re.compile('<tr class=".*?">.*?<td.*?</td>.*?<td>(.*?)</td>.*?<td>(.*?)</td>.*?</tr>', re.S)
iplist = re.findall(pattern,html)
#print(iplist)
for i in iplist:
	#print(i[0])
	#print(i[1])
	url="http://%s:%s"%(i[0],i[1])
	print(url)
