获取喜马音频

URL功能详解

1. 查询专辑列表 kw拼接搜索内容

https://www.ximalaya.com/revision/search/main?core=album&page=1&spellchecker=true&rows=20&condition=relation&device=iPhone&fq=&paidFilter=true&kw=

2. 查询节目列表 albumId拼接接口1中的albumId

https://www.ximalaya.com/revision/album/v1/getTracksList?pageNum=1&pageSize=30&albumId=

3. 查询节目详情 {{$timestamp}}内容为变量 当前时间戳，注意其他参数不要修改，如果修改会导致解密url失败 trackId为接口2中trackId

https://www.ximalaya.com/mobile-playpage/track/v3/baseInfo/{{$timestamp}}?device=web&trackQualityLevel=2&trackId=

解密URL功能

接口3中返回列表中有5种类型的音乐输出格式：M4A_64、MP3_64、M4A_24、MP3_32、AAC_24
