本人改写了个php版本

web官网歌词页经常奔溃，不稳定，下面是改用PC客户端稳定获取歌词的方法
1.在根目录引入如下 4 个包（由于酷我PC客户端歌词是加密的所以需要引入新的包进行解密）
npm install iconv-litenpm install needlenpm install processnpm install zlib2.找到
app => service => lrc.ts3.替换代码（代码是兼容的不影响其他模块）
4.原本代码如下：
5.将上面的代码替换成下面这样的代码
6.进入
.eslintrc文件，把下面代码替换（此替换不影响其他地方功能）7.使用
npm run ci编译成 js 代码8.最后启动项目
npm run start9.可以进行歌词接口代替，使用桌面客户端解密歌词接口更稳定，更快。
