## 前言
最近在某知名网站上看到自己喜欢的视频就想着下载下来，每次都用客户端、软件下载太麻烦，就想着能不能整个网页，直接下载好一键传到网盘，然后就找到了这个项目[M3U8dudu][1]，但实测用docker部署会有一些问题。
## 无法启动
碰到的第一个问题就是使用作者给的命令后容器无法启动，根本原因是挂载的/root/config目录下未生成config.ini配置文件。
[tabs]
[tab name="方法一" active="true"]
手动复制一份**config.ini**文件到**/root/config**目录下，并将启动命令修改为**python app.py --config /root/config/config.ini**

> 修改启动命令是因为，两边文件无法自动同步更改，不修改的话容器仍然以容器内部config.ini为准，后续管理起来麻烦。

[/tab]
[tab name="方法二（不推荐）"]
直接删掉**/root/config:/app/config**，取消挂载配置文件也可以启动。不过后续配置麻烦，且容器更新的话，配置文件会丢失。
[/tab]
[tab name="方法三"]
修改镜像文件，删除项目内**config文件夹及里面config.ini**，新建一个**generate_config.py**来创建配置文件，实测是可以的。不过本人测试环境误删了，导致代码保存下来 ::Heo:捂脸::

## 布局问题
项目启动后，使用电脑端访问布局错乱，手机端和平板显示正常，这里提供我修改好的index.html和play.html。

AI摘要：本文讨论了在部署M3U8视频离线下载项目时遇到的问题及其解决方案。主要问题包括容器无法启动和布局错乱。针对启动问题，提供了三种解决方法，其中手动复制配置文件为最佳选择。布局问题则通过修改HTML文件解决。此外，文章还提到上传到Alist和使用aria2下载的相关问题，并提供了相应的代码示例。最终，经过调整，项目基本可用。

使用原本上传代码，测试一直无法成功上传到alist上，不过脚本还可以完善，比如增加上传进度检测等，但实在是懒得整了，主打一个功能正常，能用就行。

然后本人aria2-pro同样是docker部署，alist可以调用，但是这个脚本一直调用不了，所有稍微修改了一下，直接调用Alist添加离线下载任务。
