案例1：使用爬虫爬取京东华为手机用户评论

　　本案例借鉴哔哩哔哩博客主视频教程，感谢其教程为我开启了爬虫之旅：https://www.bilibili.com/video/BV1Yt4y1Y7nt?t=3456。本案例主要是通过京东华为手机页面爬取了用户的评论数据，便于对华为本款手机的性能、质量、价格等多维度进行用户方面的分析。

　　案例2：使用爬虫下载百度学术论文

　　本案例主要是通过百度学术与SCI-HUB联合的方式来获取下载文献，主要步骤为进入百度学术搜索界面获取关键词搜索后的URL，在关键词跳转后的论文页面选择查看源代码找到DOI处（并采用正则表达式进行提取），提取完DOI后利用SCI-HUB搜索文献的URL方式来获取PDF下载的网址。
