feat(appearance): 主题与壁纸搬到服务端(账号级)—— 回答"为什么背景存在本地"
用户质问:「为什么背景是保存在本地而不是服务器!」当时的实情是主题与壁纸只写 localStorage:换设备/换浏览器就没了,而且**多账号共用一份**(键是全局常量 `agentmail.background`)—— 同一台机器换账号背景不跟着走。而 localStorage 的 ~5MB 配额也解释了客户端那套"压到 2.4MB 以内"的限制本来就是为本地存储设计的。 现在:**服务端是权威(账号级),本地只是缓存**(首屏秒开、离线可用)。 ## 服务端 - 新表 `user_appearance`(两种方言),用**列**而不是 JSON:blob GC 要一眼看出 "这张图还有没有人用"。 - `/api/v1/me/appearance`:GET / PUT(主题+背景档)/ POST image(multipart)/ GET image / DELETE image。鉴权同其余 /me/*(cookie 或 Bearer)。 - 图片走**内容寻址的 blob 存储**(与附件同一套),库里只存 sha256;上限 4MB 兜底 (客户端会先压到 ~2.4MB),只收图片类型(非图片 415 —— 浏览器会把非图片渲染成 空白,用户只会看到"设置了却没变化"),超限 413 不静默截断。 - ★ **blob GC 的引用源加了这张表**:我在实现前先读了 `SweepUnreferencedBlobs`, 它只认 attachments / calendar_attachments。漏了这一处,壁纸会在下次 GC 时被当 孤儿删掉,而库里那行还在 —— 表现为"图 404、设置却显示已设置"。判据同时验了 壁纸存活**与**孤儿确实被清(否则"还在"可能只是因为 GC 没跑)。 ## 客户端 - `lib/appearance.ts`(纯函数:两侧形状换算、data URL→Blob)+ `stores/appearanceSync.ts` (pull / push / 去抖订阅 / 账号切换重新拉取)。 - 三条不变量都有判据:拉取以服务端为准;★ **拉取不会再推回去**(否则是自触发回环, 一次拉取顺带一次 PUT,服务端 updated_at 被无意义刷新);本地改动会推上去。 - 壁纸**只在换图时上传一次**(几 MB 不该每次 PUT 都跟着走)。 - 降级**必须可见**:未登录/不可达 → `local-only`,推失败 → `pending`,背景设置里 有徽标与说明("已同步 / 待同步 / 仅本机")。静默降级会让人以为已经同步, 然后在另一台机器上发现没有 —— 正是这次的缺陷。 - 图片用**带认证的 fetch** 取回再转 data URL:`<img src>` 发不出 Bearer,而 `?token=` 会把密钥写进历史记录与服务端日志(明确不做)。 ## 判据 - Go 10 条:往返、★多账号隔离、非法值归一、上传/取回字节一致、非图片 415、 超限 413、删除、未登录 401(五个端点)、★GC 存活 + 孤儿对照。 - 客户端 10 条:形状换算、image 无图退回 none、越界夹取、拉取生效、 ★拉取不推送、推送 payload、未登录/500 → local-only、推失败 → pending、 ★壁纸只上传一次。 - 全量:server 10 包全绿、客户端 249 通过(含打包一致性判据 —— 它先红后绿, 因为前端改了必须重打安装包,这条护栏是先前特意留下的)。 ## 线上验证与交付 - jianf 设置 → 回包 saved=true;**gui-lab 读到自己那份默认值**(隔离生效); gui-lab 上传 67B PNG → 取回 sha256 一致、`has_image=true`;DELETE 后 404。 - 网关已重打(WebUI 内嵌)并部署;Electron 安装包已重打(AppImage + deb)。 遗留:鸿蒙端还没有外观功能(数据已在服务端,将来可直接读);本地缓存仍在(离线可用)。

# 为什么要有这套端点
|
||||
|
||||
2026-09-13 用户的质问:「为什么背景是保存在本地而不是服务器!」
|
||||
当时的实情:主题与壁纸只写浏览器 localStorage,于是换设备/换浏览器就没了,
|
||||
更糟的是**多账号共用一份**(存储键是全局常量)—— 同一台机器换账号,背景不跟着走。
|
||||
而 localStorage 只有 ~5MB 配额,客户端不得不把手机照片压到 2.4MB 以内(那套限制
|
||||
本身就是"为本地存储而设计"的痕迹)。
|
||||
|
||||
放服务端之后:账号级、跟设备无关、多账号各自一份;客户端保留本地缓存用于秒开与离线。
|
||||
|
||||
# 图片为什么不塞进 JSON
|
||||
|
||||
图片走**内容寻址的 blob 存储**(与附件同一套),库里只存 sha256 —— 这样
|
||||
`repo.SweepUnreferencedBlobs` 能一眼看出这张图还有没有人用(它读的就是这张表)。
|
||||
塞进 JSON 的话 GC 就得在 SQL 里解析 JSON,而两种方言写法还不一样。
|
||||
|
||||
# 鉴权
|
||||
|
||||
与其余 /me/* 一样要求登录(cookie 或 Bearer)。图片 GET 也要求 —— 客户端用
|
||||
带认证的 fetch 取回来再转 object URL,**不接受 `?token=`**(那会进日志与历史记录)。
