分享接口返回的内容似乎不正常

[whis7766]

通过分享返回的订阅和直接查看订阅的返回内容不一致(同一段时间),似乎分享接口存在十分钟左右的延迟,已排除client缓存问题.似乎和cloudflare的缓存有关?

curl "https://xxxxxx.pages.dev/share/col/sameitem?token=xxxxx" -H "accept: application/json, text/plain, /" -H "user-agent: clash.meta"

这两个请求同一时间发出的

感谢反馈，已定位并修复。

原因： Cloudflare CDN 边缘缓存。Workers 返回的 API 响应之前未设置 Cache-Control 头，Cloudflare 边缘节点会按 URL 路径独立缓存响应内容。/share/col/xxx 和 /download/collection/xxx 虽然调用相同的后端逻辑，但 URL 不同 → 缓存 key 不同 → 各自命中不同时间点的缓存快照，导致同一时间请求到的数据不一致。

你用 curl 测试排除了客户端缓存，判断是对的，问题确实在 Cloudflare CDN 层面。

修复： 已在所有 API 响应上添加 Cache-Control: no-store 和 CDN-Cache-Control: no-store，明确禁止 Cloudflare CDN 缓存动态响应。更新部署后两个接口应返回一致数据。

如果部署后仍有残留旧缓存，可在 Cloudflare Dashboard 手动 Purge Cache 一次。
