使用--enable-rpc 启动 aria2c, 把access_token替换成你自己的，执行此脚本就可以使用aria2下载百度云的文件了.

执行bypy.py info 根据提示完成验证授权之后，就可以在/home/$USER/.bypy.json 文件找到access_token

经研究发现可以使用带用户密码的aria2,如何：http://username:password@127.0.0.1:6800/rpc,
但是如何使用启用secret token的aira2呢，搜索了半天没有找到办法，求指点

终于知道怎么使用了，aria2.addUri("token:$$secret$$", ["http://example.org/file"])
