一、工具
- python3
- 第三方类库requests
- python3-pyqt5(gui依赖，不用gui可不装)
ubuntu系列系统使用以下命令安装依赖：
url格式: 漫画首页的url，如http://m.ac.qq.com/comic/view/id/518333(移动版) 或 http://ac.qq.com/comic/comicinfo/id/17114, (pc版)
注意: 火影忍者彩漫需要访问m.ac.qq.com搜索火影忍者，因为pc端页面火影忍者彩漫和黑白漫画是一个id一个url。
二、命令行帮助
usage: getcomic.py [-h] [-u url] [-p path] [-d] [-l list]
*下载腾讯漫画，仅供学习交流，请勿用于非法用途*
空参运行进入交互式模式运行。
optional arguments:
-h, --help show this help message and exit
-u url, --url url 要下载的漫画的首页，可以下载以下类型的url:
http://ac.qq.com/comic/comicinfo/id/511915
http://m.ac.qq.com/comic/comicinfo/id/505430
http://pad.ac.qq.com/comic/comicinfo/id/505430
http://ac.qq.com/naruto
-p path, --path path 漫画下载路径。 默认: /home/fengyu/tencent_comic
-d, --dir 将所有图片下载到一个目录(适合腾讯漫画等软件连看使用)
-l list, --list list 要下载的漫画章节列表，不指定则下载所有章节。格式范例:
n - 下载具体某一章节，如-l 1, 下载第1章
n,n... - 下载某几个不连续的章节，如 "-l 1,3,5", 下载1,3,5章
n-n... - 下载某一段连续的章节，如 "-l 10-50", 下载[10,50]章
杂合型 - 结合上面所有的规则，如 "-l 1,3,5-7,11-111"
三、gui预览效果
支持不连续的章节选择下载
windows预览效果：
deepin/linux 预览效果：
