再也不用花钱买漫画!Python爬取某漫画的脚本及源码-巨人网络通讯

再也不用花钱买漫画!Python爬取某漫画的脚本及源码

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, http://ac.qq.com/naruto(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
