本文文章主要介绍Python爬虫抓取百度搜索内容的代码示例。本文通过示例代码介绍了非常详细的示例。它对每个人的学习或工作都有一定的参考学习价值。需要它的朋友可以参考以下内容
搜索引擎使用非常频繁。现在,使用Python采集器来提取百度搜索内容,同时,可以通过进一步提取内容并对其进行分析来简化搜索过程。详细情况如下:
代码如下
# coding=utf8
import urllib2
import string
import urllib
import re
import random
#设置多个user_agents,防止百度限制IP
user_agents = ['Mozilla/5.0 (Windows NT 6.1; WOW64; rv:23.0) Gecko/20130406 Firefox/23.0',
'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/20100101 Firefox/18.0',

'IBM WebExplorer /v0.94', 'Galaxy/1.0 [en] (Mac OS X 10.5.6; U; en)',
'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0)',
'Opera/9.80 (Windows NT 6.0) Presto/2.12.388 Version/12.14',

'Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.0; Trident/5.0; TheWorld)']
def baidu_search(keyword,pn):
p= {'wd': keyword}
res=urllib2.urlopen(("http://www.baidu.com/s?"+urllib.urlencode(p)+"&pn={0}&cl=3&rn=100").format(pn))
html=res.read()
return html
def getList(regex,text):
arr = []
res = re.findall(regex, text)
if res:
for r in res:
arr.append(r)
return arr
def getMatch(regex,text):
res = re.findall(regex, text)
if res:
return res[0]
return ""
def clearTag(text):
p = re.compile(u']+>')
retval = p.sub("",text)
return retval
def geturl(keyword):
for page in range(10):
pn=page*100+1
html = baidu_search(keyword,pn)
content = unicode(html, 'utf-8','ignore')
arrList = getList(u".*?</a>", content)
for item in arrList:
regex = u"(.*?)</a>"
link = getMatch(regex,item)
url = link[0]
#获取标题
#title = clearTag(link[1]).encode('utf8')
try:
domain=urllib2.Request(url)
r=random.randint(0,11)
domain.add_header('User-agent', user_agents[r])
domain.add_header('connection','keep-alive')
response=urllib2.urlopen(domain)
uri=response.geturl()
print uri
except:
continue
if __name__=='__main__':
geturl('python')
