有时候看到好看的抖音，听到喜欢听的背景音乐但音乐却没有在音乐软件上架怎么办？下面代码直接实现。

实现原理

随便用一个妹妹试一下，咱主要不是看妹子，是单纯的想要背景音乐而已好吧。
从抖音复制来的链接 https://v.douyin.com/JwR69Lk

直接用做成的api解析一下，默认是这个链接，可以做成api，直接后面跟 url参数 就行了，直接就得到了背景音乐。例如： 我做个API测试了一下：https://www.q6q.cc/api/douyinbgm/api.php?url=https://v.douyin.com/JwR69Lk ，直接访问就能看到背景音乐直链。

来首DJ，来首DJ～～～
