360搜索引擎取真实地址-python代码

还是个比较简单的，不像百度有加密算法

分析

http://www.so.com/link?url=http%3A%2F%2Fedu.sd.chinamobile.com%2Findex%2Fnews.do%3Faction%3DnoticeDetail%26id%3D22452&q=inurl%3Anews.do&ts=1488978912&t=89c5361a44fe3f52931d25c6de262bb&src=haosou

网址是上面这个样子，没加密直接取就好了，去掉头http://www.so.com/link?url=和尾&q=一直到末尾的部分，剩下的就可以吃了

那么规则我们就可以写出来了

a['href'][a['href'].index('?url='):a['href'].index('&q=')][5:]

a['href']是待处理网址,a['href'].index('?url='):a['href'].index('&q=')的部分为?url=http%3A%2F%2Fedu.sd.chinamobile.com%2Findex%2Fnews.do%3Faction%3DnoticeDetail%26id%3D22452

最后还需要用unquote解码

  • 在python3中是urllib.parse.unquote
  • 在python2中是urllib.unquote

code

import requests

from bs4 import BeautifulSoup

from urllib.parse import unquote

headers = {

    "User-Agent" : "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:53.0) Gecko/20100101 Firefox/53.0"

}

#爬取360搜索引擎真实链接，第一个参数关键词str，第二个参数爬取页数int

def parse360(keyword, pagenum):

    keywordsBaseURL = 'https://www.so.com/s?q=' + str(keyword) + '&pn='

    pnum = 1

    while pnum <= int(pagenum):

        baseURL = keywordsBaseURL + str(pnum)

        try:

            request = requests.get(baseURL, headers=headers)

            soup = BeautifulSoup(request.text, "html.parser")

            urls = [unquote(a['href'][a['href'].index('?url='):a['href'].index('&q=')][5:]) for a in soup.select('li.res-list > h3 > a')]

            for url in urls:

                yield url

        except:

            yield None

        finally:

            pnum += 1

用法示例:

def main():

    for url in parse360("keyword",10):

        if url:

            print url

        else:

            continue

if __name__ == '__main__':

    main()
