6 | 7 | > 基于的是早期版本，可能和源项目有些不一样。 8 | 9 | 更改内容： 10 | - 移除Docker部署、Python部署，只保留Cloudfare Worker部署 11 | - 修改为可自定义镜像地址，方便自定义 12 | 13 | 14 | ## 演示 15 | 16 | [https://tool.mintimate.cn/gh](https://tool.mintimate.cn/gh) 17 | 18 | 演示站为公共服务，如有大规模使用需求请自行部署，演示站有点不堪重负 19 | 20 | ![imagea272c95887343279.png](https://img.maocdn.cn/img/2021/04/24/imagea272c95887343279.png) 21 | 22 | 23 | ## 使用 24 | 25 | 直接在copy出来的url前加`https://tool.mintimate.cn/gh/`即可。 26 | 27 | 如果是自己搭建的，一般为`https://**.workers.dev/`，将这个追加到需要加速的GitHub连接前即可。 28 | 29 | 30 | 以下都是合法输入（仅示例，文件不存在）： 31 | 32 | - 分支源码：https://github.com/Mintimate/project/archive/master.zip 33 | 34 | -

building`，取一个子域名，`Create a Worker`。 49 | 50 | 复制 [index.js](https://cdn.jsdelivr.net/gh/hunshcn/gh-proxy@master/index.js) 到左侧代码框，`Save and deploy`。如果正常，右侧应显示首页。 51 | 52 | `index.js`默认配置下项目文件会走jsDelivr，如需走worker，修改Config变量即可 53 | 54 | `ASSET_URL`是静态资源的url（实际上就是现在显示出来的那个输入框单页面） 55 | 56 | `PREFIX`是前缀，默认（根路径情况为"/"），如果自定义路由为example.com/gh/*，请将PREFIX改为 '/gh/'，注意，少一个杠都会错！ 57 | 58 | 59 | ## 注意 60 | 61 | python版本的机器如果无法正常访问github.io会启动报错，请自行修改静态文件url 62 | 63 | workers版本默认配置下项目文件会走jsDelivr，如需走服务器，修改配置即可 64 | 65 | 66 | ## Cloudflare Workers计费 67 | 68 | 到 `overview` 页面可参看使用情况。免费版每天有 10 万次免费请求，并且有每分钟1000次请求的限制。 69 | 70 | 如果不够用，可升级到 $5 的高级版本，每月可用 1000 万次请求（超出部分 $0.5/百万次请求）。 71 | 72 | ## Changelog 73 | 74 | * 2020.04.10 增加对`raw.githubusercontent.com`文件的支持 75 | * 2020.04.09 增加Python版本（使用Flask） 76 | * 2020.03.23 新增了clone的支持 77 | * 2020.03.22 初始版本 78 | 79 | -------------------------------------------------------------------------------- /index.js:
