## 本次更新
|
||
|
||
### 修复网页更新出现 502
|
||
|
||
- 修复后台点击“立即更新”后，Watchtower 在替换业务容器时切断原更新请求，导致页面错误显示 `502 Bad Gateway` 或“更新失败”的问题。
|
||
- 更新接口现在会先完成数据库备份并向网页返回 `202 Accepted`，再异步触发容器更新，避免旧容器停止时丢失响应。
|
||
- 前端遇到更新期间的 `502`、`503`、`504`、网络中断或请求超时时，会继续轮询服务健康状态；确认目标版本启动后自动刷新页面。
|
||
- Watchtower 调用等待时间延长到 10 分钟，兼容首次拉取较大镜像或网络较慢的服务器。
|
||
|
||
### 更新说明
|
||
|
||
- 网页更新仍会在替换容器期间产生数秒正常中断，页面会显示“正在重启服务”，恢复后自动刷新。
|
||
- 更新前仍会自动备份 SQLite 数据库，现有邮件、账号、域名、证书和配置不会删除。
|
||
- 从 `v1.2.6` 更新到本版时，旧页面尚未包含此次容错逻辑，建议在服务器运行 `sudo newszxcn-email update` 完成这一次升级；进入 `v1.2.7` 后，后续版本可正常使用网页更新。
|
||
|
||
### 验证
|
||
|
||
- 新增异步更新回归测试：即使 Watchtower 更新请求保持阻塞，网页也必须先收到更新已受理响应。
|
||
- 已通过 Go API 测试、前端生产构建和 shadcn/ui 检查。
