好久没上来写博客了，直入主题。

大家经常用google搜索，如何提取搜索结果的链接呢

google搜索结果url提取,F12,来到console端; 粘贴下面语句，回车。

var tag=document.getElementsByClassName('r');

 for (var i=0;i

提取出来，保存到url.txt. 待检测的url和域名，一行一个,先经过去重去空白行

import io
import shutil
readPath='oldurl.txt'
writePath='url.txt'
lines_seen=set()
outfiile=io.open(writePath,'a+',encoding='utf-8')
f=io.open(readPath,'r',encoding='utf-8')
for line in f:
    if not len(line):
        continue
    if line not in lines_seen:
        outfiile.write(line)
        lines_seen.add(line)

然后再批量检测

ok.txt 域名正常

red.txt 已经屏蔽的域名和链接

import requests

result = list()
strxx = '"Code":"102"'
html = ''
for y in linecache.updatecache(r'url.txt'):

       #response = urllib.urlopen(x)        
       #html = response.read()
       x = 'http://wx.rrbay.com/pro/wxUrlCheck.ashx?url=' +  y
       response = requests.get(x,headers=headers)
       html = response.text

       time.sleep(3)
       #print x,a
    except Exception,e:
        html = ''
        print e
    if strxx in html:
        print 'ok:'
        print x
        with open ('ok.txt','a') as f:  
            f.write(y)
    else:
        print 'error:'        
        print y
        html = ''
        with open ('red.txt','a') as f:  
            f.write(y)
