基于NFC（215芯片）和酷狗音乐实现NFC音乐墙

前言：

本文方案可以实现直接调起酷狗音乐app自动播放，而非跳转网址

准备工作：

nfc tools
nfc task
酷狗音乐APP
alook浏览器APP

步骤

1.选一首歌
在这里插入图片描述
2.右上角选择分享，选择复制链接

复制内容为：

分享胡夏的单曲《爱夏》https://t3.kugou.com/song.html?id=13bWedaCJV3 （@酷狗音乐）

只保留网址部分，如下：

https://t3.kugou.com/song.html?id=13bWedaCJV3

3.用alook浏览器打开，
在这里插入图片描述
4.点击打开酷狗，拷贝链接

但是酷狗的url太长了，nfc里放不下，所以我们需要删减一部分，

处理URL

拷贝链接如下，

可以看到有一些乱码，放到chatgpt中转码（应该有别的转码方式，但是我没去进一步的找），因为这段 URL 地址，它采用了 URL 编码。URL 编码是为了在 URL 中安全传输特殊字符而进行的一种转义处理。

提供的 URL 地址经过解码后是：

kugou://start.weixin?{"cmd":212,"jsonStr":{"hash":"d85e2023bc102e9912713a21ec612e56","filename":"曲婉婷 - 我的歌声里","bitrate":128,"duration":216,"extname":"mp3","privilege":8,"320privilege":10,"sqprivilege":10,"album_audio_id":27358902,"trans_param":{"cpy_grade":5,"musicpack_advance":0,"qualitymap":{"attr0":1128251445},"cpy_level":1,"cpy_attr0":64,"ipmap":{"attr0":4096},"cid":32590233,"hash_multitrack":"757CA5E24585DD8D5F0CB9141F25F4D6","pay_block_tpl":1,"classmap":{"attr0":234881032},"display_rate":0,"appid_block":"2906,3124","display":0,"language":"国语","hash_offset":{"start_ms":0}},"fail_process":0,"pay_type":0,"needfav":false,"btnh5":5,"cyt2":"openAppBtn","userid":"2153285810","chl":"link","chl2":"","secondShareChl":"","vip_share_activity":"","u":"2153285810","h1":"266240133806765453580375580512035942735","h2":"-","cyt1":"其他","ua_plat":"other","page_path":"/share/"},"openBIData":{"key":"d373be6a0f5f62330eedaad97276563e","actid":"","kugouid":0,"url":"https://m.kugou.com/share/","ua":"mozilla/5.0 (linux; android 12; els-an00 build/huaweiels-an00) applewebkit/537.36 (khtml, like gecko) version/4.0 chrome/96.0.4664.104 mobile safari/537.36","expand":""}}

这段 JSON 数据包含了一些音频文件的信息，但是实际上我们不需要那么多，删减只保留以下信息即可，这段url是后面要使用的url,
