前言

大家好我叫善念

CSDN很好的，把一群喜欢编程的小伙伴都聚集在了一起，
平时也喜欢来逛逛，学习一些大佬的经验，
现在，我也来分享一下

使用前说明

1. 考虑到一部分小伙伴编码基础薄弱，接下来，我也会详细的解说一下，

2. 阉割了决议后直接播放的功能，如果需要，可以将代码里播放的功能位置，把注释去掉即可，懂的应该能懂，

关于 cookie的获取：
打开优酷首，按F12 （这是一个功能键），打开到网络，然后重绘浏览器！

这样就抓到包了，找到首页的包，点击一下，如图所示，复制这里的 cookie

然后再粘贴到决议工具里面！！！最后找到需要决议的视频链接，粘贴进去，，，，

接下来，就决议完成了，

接下来，就是复制m3u8地址，找个下载工具就能下载了，
