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<tag.length;i++){
var a=tag[i].getElementsByTagName("a");
console.log(a[0].href)
}
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
#! /usr/bin/env python

#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)
