大众点评加密字段解决方法

下以此店为例：

可以在源码中找到一个后缀为css的链接
访问链接得到

有六种加密字体，可以下载下来用fontcreate软件打开，试了多种办法没有找到快速生成对应字典的方法，那就只有手撸了。（如果你有方法，请评论分享一下，大家共同进步）

        print(phone_list)
        print(phone_content)
        print(time_class)
        print(time_list)
        print(time_content)
        
if __name__ == '__main__':
    dz = DaZhong()
    dz.get_content()

结果如下：

然后对拿到的加密字段用字典进行解密，拼接可得到明文。
