今天要分析的网站是一款音乐网站，此网站无需登录，而且所有的歌曲内容都可以下载，全部免费，但每天的下载量有限制，今天就来解决这个问题，实现无限下载次数

1、打开某某网站（使用文章开头的AES在线工具解密)：

5khqlL42kPT6xNWhBbV4MbNWMWI/iO0K9bnAJp5+P0Y=

2、打开网站后，我们随便打开一个音乐，然后点击下载歌曲，然后会弹出一个页面，这个页面会限制剩余多少次下载次数，我已经用完了，想要再次下载就必须要在指定的小程序看广告，才能获取口令码，才能再次下载歌曲，而且这个口令码有时间限制，只能用一天，所以很是麻烦

3、我们输入一个正确的口令码，然后提交，可以发现，他返回了一个cookie，这个cookie就是无限下载的通行令牌，但他的cookie有时间限制，设置了一天的时间，时间到后就会自动清除cookie,所以看到这里你就应该懂了

4、可以看到他已经成功实现无限下载了，这种是需要口令码的，而且口令码会变，而且还要看广告，很是繁琐，并且只有一天的时间限制

5、接下来请用这样的一段代码，需要搭配油猴脚本运行，即可实现无需口令码、无次数限制、无时间限制的永久免费无次数限制下载。

【油猴脚本内容】请将此代码粘贴到油猴脚本内进行执行
