第1种方法——you-get

You-get是一个小型的命令行实用程序，用于从Web下载媒体内容。使用需要python环境支持。参考教程

安装

使用pip安装you-get，输入

      pip install you-get

安装完毕后可以直接在cmd中使用you-get命令进行下载。

使用

以优酷网的电影《妖猫传》《末代皇帝》为例（非会员电影），演示you-get的使用效果。

使用-i选项查看所有可用的品质和格式,标记的格式DEFAULT是将默认获得的格式，默认格式是质量最高的格式。

      you-get -i https://v.youku.com/v_show/id_XMzM3NDMxOTE0NA==.html?spm=a2h0c.8166622.PhoneSokuProgram_1.3
