前言:
之前收藏了一个叫微信公众号的文章爬取,里面用到的模块不错。然而
偏偏报错= =。果断自己写了一个
正文:
第一步爬取搜狗微信搜到的公众号:
http://weixin.sogou.com/weixin?type=1&query=FreeBuf&ie=utf8&s_from=input&_sug_=n&_sug_type_=1&w=01015002&oq=&ri=11&sourceid=sugg&sut=0&sst0=1529673558816&lkt=0%2C0%2C0&p=40040108
将FreeBuf改为自己要搜的公众号
查看网页源代码:
正则匹配:
第一个正则:匹配指定的URL 正则: src=.*&timestamp=.*&ver=.*&signature=.*
蓝色标出来的是我们要的,注意多请求URL可以注意到URL,signature也就是签名是随机变化的。所以可得到正则:.*== ,取第一个,然后打开此链接爬取文章链接即可(更多细节会在代码看到)
代码:
