主要流程：
第一：访问行业分类页面，获取该行业公司及对应代码，并将数据封装为一个列表。
本文中访问行业包括G53:铁路运输,G54:道路运输,G55:水上运输,G56:航空运输,G58:装卸搬运和运输代理,G59:仓储业,G60:邮政业，各行业对应链接格式如下：
http://www.sse.com.cn/assortment/stock/areatrade/trade/detail.shtml?csrcCode=行业代码
如铁路运输为：
http://www.sse.com.cn/assortment/stock/areatrade/trade/detail.shtml?csrcCode=G53
第二：根据封装的公司及代码数据进入定期报告页面，通过selenium模拟键入、点击等操作。
随后进入该公司信息页面，通过selenium对页面数据进行抓取，并进行数据筛分，获取2021~2012年年报数据。
详细代码如下：
