python表情包爬虫程序_Python网络爬虫爬取站长素材上的表情包

矫情吗；* 2022-10-28 00:57 170阅读 0赞

由于经常看群消息，收藏的表情包比较少，每次在群里斗图我都处于下风，最近在中国大学MOOC上学习了嵩天老师的Python网络爬虫与信息提取课程，于是决定写一个爬取网上表情包的网络爬虫。通过搜索发现站长素材上的表情包很是丰富，一共有446页，每页10个表情包，一共是4000多个表情包，近万个表情，我肯以后谁还敢给我斗图

网页分析

站长素材第一页表情包是这样的：

![0818b9ca8b590ca3270a3433284dd417.png][]

接下来是分析每一页表情包列表的源代码：

再来分析每个表清包全部表情对应的网页：

步骤

1、获得每页展示的每个表情包连接和title

2、获得每个表情包的所有表情的链接

3、使用获取到的表情链接获取表情，每个表情包的表情放到一个单独的文件夹中，文件夹的名字是title属性值
