搭建免费图床服务 ​

  • Github仓库有大小限制，虽然已经足够。之前将md和图片放到一起，现在做分离。方便管理和加快部署，图片单独存储
  • 使用typora+picList可以迁移原来的本地图片

github ​

  • 创建图片存储仓库如image_bed_0，私有即可
  • 创建和保存Github PAT(后续要用)，用户头像->settings->Developer Settings->Personal access tokens (classic),，勾选仓库权限

cloudflare配置 ​

创建Workers ​

  • 替换代码如下方js，部署
  • 你需要替换代理路径和令牌(PAT)

部署成功后提示非法请求是正常的，你访问具体的仓库资源就没问题

js
// Website you intended to retrieve for users.
const upstream = "raw.githubusercontent.com";

// Custom pathname for the upstream website.
// (1) 填写代理的路径，格式为 /<用户>/<仓库名>/<分支>
const upstream_path = "/banzidev/img/main";

// github personal access token.
// (2) 填写 github 令牌
const github_token = "ghp_xxx";

// Website you intended to retrieve for users using mobile devices.
const upstream_mobile = upstream;

// Countries and regions where you wish to suspend your service.
const blocked_region = [];

// IP addresses which you wish to block from using your service.
const blocked_ip_address = ["0.0.0.0", "127.0.0.1"];

// Whether to use HTTPS protocol for upstream address.
const https = true;

// Whether to disable cache.
const disable_cache = false;

// Replace texts.
const replace_dict = {
  $upstream: "$custom_domain",
};

访问图片 ​

PicList配置 ​

PicList ​

该软件操作参考PicGO，结合typora使用即可实现图片自动上传和迁移

  • 你可以在插件中搜索压缩插件进行图片自动压缩，添加水印等

  • 可以在设置中转换图片的格式和开启时间戳重命名

Github图床配置 ​

  • 说明

    • 仓库：用户名/仓库名
    • token: 就是前面创建的PAT或重新创建一个
    • 自定义域名：直接使用cloudflard提供给你的域名

    这里我使用的是自定义域名(下方有描述)，用自定义域名和它提供的都可以

image-20250219114226702

自定义域名 ​

  • 需要你有一个域名并由cloudflard托管(不在多说)
  • 然后直接添加即可
  • 访问路径和之前一样域名链接/图片，如下图的访问路径https://img.simpleword.bid/20250219114700750.webp
