折腾/memos
想到了如何通过CF Workers 让新版Memos 兼容广场,以下代码AI生成
新建一个workers

}
/* ---------- 工具：建立 UID↔数字 双向映射 ---------- */
async function getNumericId(uid) {
let num = await KV.get(`uid:${uid}`);

} 把https://memos.ee更改为自己的memos地址 把代码粘贴进去 点击部署
在KV中新建一个数据库命名空间随便填写
在workers中绑定命名空间 变量名称MEMOS_MAPKV 命名空间选择上面创建好的
最好给workers绑定好域名例如 https://old.memos.ee
使用memobbs 广场演示 https://memobbs.memos.ee
