问题稳定复现。

[Wesley-Young]

根因是这里的 receiver uid 解析问题:

acidify/acidify-core/src/commonMain/kotlin/org/ntqqrev/acidify/FileOps.kt

Line 178 in 2fa2c51

receiverUid = getUidByUin(friendUin),

这里默认用了好友的 uid 作为 receiver uid, 但实际上如果是别人发给自己的文件(大多数情况下都是这样)，receiver uid 应该填自己的, 而这里没有相应的逻辑.

可能的修复方法有下面几种, 按优雅程度从低到高排名:

1. 用对方 uid / 自己 uid 各试一次, 或者进行一个 race, 哪个成功了就用哪个的结果;
2. 拉取最近的 30 条消息, 逐个比对 file id, 从而确定接收方是谁;
3. 对 Milky 协议动刀子, 但这很可能引入破坏性变更, 需要进一步讨论.

你觉得用哪一种比较好呢?

[Wesley-Young]

推了一个更新，把 receiverUid = this.uid 作为了默认行为，应该能缓解大部分使用场景的问题，但归根结底还是应该给这个 API 增加一个字段. 我会在 Milky 开一个 Issue.
