4 | # 修改配置
5 |
6 | 修改 `www/conf.js` 配置，发布 `www` 目录即可。
7 |
8 |
9 | ## TODO
10 |
11 | * 增加网络错误重试、优先选择空闲节点功能
12 |
13 | * 在 SW 中替换 HTML 的 URL 属性，并支持流模式
14 |
15 | * CDN 文件使用 brotli 压缩
16 |
17 | * 使用 AST 修改 JS 代码
18 |
19 | * 动态页面压缩传输（反模板引擎，只传输变量，模板本身存储在 CDN）
20 |
21 | * 使用更多的免费图床作为 CDN 资源存储，并支持 Hash 校验
22 |
23 | * 计算程序使用 wasm 实现
24 |
25 | * 支持 blob/data/javascript 协议
26 |
27 | * 增加 qos 功能，优先满足资料查询网站流量
28 |
29 | * 改进同源策略的安全性，增加部分 API 的授权界面
30 |
31 | * 重新设计首页，增加更多功能
32 |
33 | * 完整的测试案例
34 |
35 |
36 | # 已知问题
37 |
38 | * 文件下载对话框取消后 SW 仍在下载（fetch.signal 的 onabort 未触发，可能是浏览器 BUG）
39 |
40 | * Chrome 图片无法保存
41 |
42 | * 非 UTF8 编码的 JS 会出现乱码（MIME 未指定 charset 的情况下出现）
43 |
44 | * Google 登陆页无法下一步
45 |
46 | * Google reCAPTCHA 无法执行
47 |
48 | * Google Maps 切换到卫星地图后卡死
49 |
50 | * iOS Safari 无法播放 Youtube 视频
51 |
52 | * twitter 在 Chrome 普通模式下无法登陆，但隐身模式可以
53 |
54 | * twitter iframe 经常加载不出来
55 |
56 | * SVG 脚本没有处理
57 |
58 | * Youtube 视频全屏播放会卡住
59 |
60 | * twitch.tv 首页报错（JS 代码修改导致错误，需要在 AST 层面修改）

1 | ## 404.html
2 |
3 | 该页面用于安装 Service Worker。
4 |
5 | 因为本项目只有一个 404.html，所以访问任意路径都会触发该页面。通过该页面安装 Service Worker 然后自动刷新，后续所有流量都可被 Service Worker 接管。
6 |
7 |
8 | ## sw.js
9 |
10 | Service Worker 脚本。
11 |
12 | 虽然 Web 标准规定 Service Worker 脚本必须和站点同源，但是 JS 可通过 `importScripts` 加载站外脚本。因此可将主体代码部署在 CDN，该脚本仅仅作为一个加载器。
13 |
14 |
15 | ## build.sh
16 |
17 | 压缩当前目录 404.html 到 ../../www/404.html
18 |
19 |
20 | ## conf.js
21 |
22 | 配置文件。该文件首次运行时动态加载
23 |
24 |
25 | ## assets
26 |
27 | 该目录存放静态资源，可部署到 CDN。
