考研帮app文章抓取 1.准备工作 文章中使用的库有:requests,json,threading,lxml,pandas 文章中使用工具:Pycharm,Fiddler
2.抓包 搜索想要爬取的内容用fiddler进行抓包 ![](https://i-blog.csdnimg.cn/blog_migrate/d86b78709375552b88ad67958e53e754.png)
3.分析 查看包内容我们可以发现json中有我们想要的数据
复制json对其进行格式化显示,可以发现data下共15个对象,我们打开看下 ![在这里插入图片描述](https://i-blog.csdnimg.cn/blog_migrate/5a7576e43456fdc6a99c25852baf5e95.png)
从data中获取我们想要的信息 abstract:摘要title:标题uuid:文章idname:作者名称
分析请求头url地址:/api-cpp/news/search?search_content=%E7%AC%94%E8%AE%B0&page=1看到page=1我们不妨大胆猜测一下是第一页内容,那么第二页就是将1改成2
#构键前10页urldef url_craet():url = 'http://api.qz100.com/api-cpp/news/search?search_content=%E7%AC%94%E8%AE%B0&page={}'url_list = [url.format(i) for i in range(1,11)]return url_list 对第一篇文章进行抓包,发现url:/a/?id=dfb029db9b304ea5ac8e32a298a16de9 文章id=dfb029db9b304ea5ac8e32a298a16de9 ,而第一篇文章的uuid就是dfb029db9b304ea5ac8e32a298a16de9
对文章发送请求,打开开发者进行元素定位再用xpath提取文章内容 ![在这里插入图片描述](https://i-blog.csdnimg.cn/blog_migrate/009d270b12e8bd85bf0b10fd74ad39ab.png)
