python制作快递查询小软件

用python制作快递查询小软件，使用Pycharm+Python+PyQt5

快递查询实现思路

• 通过对网址http://www.kuaidi100.com/ 抓包，发现通过self.url1 = r'http://www.kuaidi100.com/autonumber/autoComNum?text={}' {}内为快递单号，通过这个链接判断可能的快递公司。
• 通过查询出来的快递公司代码，与快递单号，拼接成网址self.url2 = r'http://www.kuaidi100.com/query?type={}&postid={}' 来查询物流信息
