<p>网易云官方有个这个东西http://music.163.com/song/media/outer/url?id=id.mp3，将id换为歌曲id进行访问就会302到歌曲地址。</p><p>其实这就可以拿来直接用了，但是他默认的都是http渠道的而非https，即使你访问https://music.163.com/song/media/outer/url?id=id.mp3最后他跳转到的也是http的音乐链接。</p><p>其实他本身是支持https的，只是全都默认http，这就很难受，所以我用php写了个小工具。</p><div><pre><span><span><?php</span>
