||||||
|
// 从QQ音乐下载歌词
|
||||||
|
const qrcTextFromNetwork = await utils.downloadQQMusicLyric({songID: 102878776})
|
||||||
|
console.log(qrcTextFromNetwork) //输出qrc歌词的XML文本
|
||||||
|
|
||||||
|
|
||||||
|
// 解码.qrc格式的歌词
|
||||||
|
const qrcTextFromFile = qrc.decrypt(fs.readFileSync('path to .qrc file'))
|
||||||
|
console.log(qrcTextFromFile) //输出qrc歌词的XML文本
|
||||||
|
|
||||||
|
// 歌词内容解析
|
