介绍

经常发现很多用gitbook生成的书籍质量很高
就想离线下来看
但是gitbook生成的pdf都无法复制且体积很大
有的网站甚至不提供下载的选项
就和小伙伴一起做了个工具
对于gitbook生成的网站进行抓取
解析以后使用weasyprint进行生成文件

特性

异步抓取使用aiohttp抓取对于网站内容抓取基本秒速完成
文本可复制
保持原目录结构
保留原文链接

完整还原原 html 页面样式
体积小，800+页的 pdf 只占用 4.6M

没有 usage 吗？
看代码貌似是直接修改 main 里面那个 run 的 url ？

ps：github 地址可以 append。

@mseasons 国内网络环境不太好，连接的时候 timeout 了，添加个代理试试

2019-03-07 19:13:55 +08:00

@privil 吃内存是因为`weasyprint`的问题正在尝试分片输出
@tongdongdong 出门左转`weasyprint`的 issues 区
@mseasons 我无法访问这个 url 不知道你是怎么访问的希望你可以把问题以及抓取的 url 发在`issues`区
@FakeLeung 感谢提醒之前没找到 append 的按钮╮(╯_╰)╭ 另外目前是修改 url 使用等下改一下使用方法之前一直这样测试就没注意这些方面

@fuergaosi #18 抓取的时候也报错了，不过我 vps 内存真小，才 512Mb，抓原来的 k8s handbook 是不行的。

@privil 无法重现这个报错是官方推荐的锅我本来没有写 len 今天跑的时候官方提示我以后可能不让直接 if None 了就推荐写成这样结果成了个 bug 我这就去改

mseasons

2019-03-07 22:15:15 +08:00

@changjiangzzZ 不是 timeout 的问题，似乎是 https 验证的问题。我把所有的 get 请求参数增加 verify=False 就好了。

mseasons

2019-03-07 22:18:23 +08:00

@fuergaosi url 我没改，直接 git clone 下来运行的源码。我后面查了一下文档，将所有的 get 请求增加参数 verify=False 就通过了。

试了个，目录结构没保留啊，比如这个
https://go.tanglei.name/content

fuergaosi

2019-03-08 14:18:46 +08:00

@cye3s 我测试了一下目录结构保留了不过因为有两个 404 所以少了两个章节 ![kz37f1.png]( https://s2.ax1x.com/2019/03/08/kz37f1.png) 另外希望有问题可以直接发到 issues 区
@dyxang 因为我没有 windows ┑(￣Д ￣)┍

@fuergaosi 你的小工具很好用鸭，但是看到有些同学搞不定环境，所以我封装了一个容器镜像，代码在这里： https://github.com/soulteary/docker-gitbook-pdf-generator

如果你愿意稍微调整项目目录结构 & 打 release tag 的话，后续升级维护能够更方便，比如定制电子书风格, etc...
