百度公开有一个音乐接口,里面分好了频道类别。下面是3个接口的一个url地址。
const QString url_getOnlineChannel = "http://fm.baidu.com/dev/api/?tn=channellist"; //url->频道ID
const QString url_getOnlineSheet = "http://fm.baidu.com/dev/api/?tn=playlist&format=json&id="; //频道ID->歌曲ID
const QString url_getOnlineMusic = "http://music.baidu.com/data/music/fmlink?type=mp3&rate=320&songIds="; //歌曲ID->歌曲信息
访问每个url都会返回一个JSON的信息,通过解析JSON来获取其中的信息。
流程就如url地址一样,分为3步:
- 获取频道列表。
无条件访问 http://fm.baidu.com/dev/api/?tn=channellist 。
这里可以获取到所有的频道信息,如下:

} - 获取具体的歌曲信息。
同样,根据上述JSON获得 id 信息加上 http://music.baidu.com/data/music/fmlink?type=mp3&rate=320&songIds= 便可以获得某一首歌的具体信息。
如访问:http://music.baidu.com/data/music/fmlink?type=mp3&rate=320&songIds=913503 ,获得如下的json:
