alist下载

第一步 安装Alist 

https://github.com/AlistGo/alist/releases  
Windows 64位 下载 https://github.com/AlistGo/alist/releases/download/beta/alist-windows-amd64.zip

运行

alist.exe server  
在界面上可以看到密码

然后登录到

http://127.0.0.1:5244/

在后台添加百度网盘 ,打开'Web代理'

挂载路径为显示路径

根文件夹路径为百度实际路径

刷新令牌的值 从下面地址获取,也在此处登录百度网盘

https://alist.nn.ci/zh/guide/drivers/baidu.html

添加好了,设置admin密码,以便python脚本使用.

 

第二步,安装python-alist

https://libraries.io/pypi/python-alist

pip install python-alist==0.0.13.7

 

1. 主要问题：AlistClient 对象没有 fs 属性，这是因为 alist 库的 API 结构发生了变化

2. 依赖问题：缺少 h2 包，需要安装 httpx[http2]     
   
   pip install httpx[http2]
