思考
1.总的思路是从flash播放的接口中获得音频的真实地址
https://www.tingchina.com/play/yousheng/flash.asp?id=30255&inum=958。。。
url1或url2和url3拼接就是真实地址
2.推测由于网站编码为GBK，通过这个接口传入参数为中文时返回的url3中有乱码
于是从这个接口仅获取key值，其他的参数自行拼接
real_address = self.host1+'/yousheng/{}/{}/{}'.format(info['flei'],info['bookname'],info['filename'])
real_address+key即为可以访问的音频地址
3.尝试使用python的类来写，代码可能稍微有点乱
下载地址
py文件和封装后的exe文件：https://www.lanzouj.com/i8lqsmf
使用方法
1.输入有声书的id和起始下载的集数用空格隔开
例如:20459 1', '下载id为20459的有声书从第1集开始下载
id如下图
id和起始下载的集数
如果觉得可以免费评下分！
