|

### 1. 签名密钥
|
||||
|
||||
当前使用 Tauri 自动更新签名密钥对，私钥用于构建时签名，公钥写入前端配置。
|
||||
|
||||
```bash
|
||||
# 确认密钥对存在（私钥文件名以你本地实际为准）
|
||||
ls ~/.tauri/meijiaka.key ~/.tauri/meijiaka.key.pub
|
||||
```
|
||||
|
||||
- 私钥 `~/.tauri/meijiaka.key`：构建时用于签名，**不要泄露**
|
||||
- 公钥内容：已写入 `tauri-app/src-tauri/tauri.conf.json` 的 `plugins.updater.pubkey`
|
||||
- **私钥**：构建时用于签名更新包，**不要泄露，不要提交到 Git**
|
||||
- **公钥**：内容已写入 `tauri-app/src-tauri/tauri.conf.json` 的 `plugins.updater.pubkey`
|
||||
|
||||
> **注意**：如果重新生成了签名密钥对，旧版本客户端将无法通过自动更新升级（旧公钥无法验证新私钥的签名），只能手动下载重装。详细说明见本文档末尾"密钥更换与手动下载"。

## 密钥更换与手动下载
|
||||
|
||||
如果签名密钥对发生更换（例如旧私钥丢失、泄露或主动轮换）：
|
||||
|
||||
1. **旧版本客户端无法自动更新**
|
||||
- 旧客户端内置的旧公钥无法验证新私钥签名的更新包
|
||||
- Tauri updater 会在签名验证阶段失败
|
||||
|
||||
2. **必须引导用户手动下载重装**
|
||||
- 后端已提供统一下载入口：`GET /api/v1/update/download`
|
||||
- 该接口根据 `User-Agent` 自动匹配最新版本和平台安装包
|
||||
- 也支持显式传参：`/api/v1/update/download?target=darwin&arch=x86_64`
|
||||
- 返回 **302 重定向**到对应安装包的七牛云 URL
|
||||
|
||||
3. **分发链接示例**
|
||||
- 网页/文档固定链接：`https://dev.tapi.meijiaka.cn/api/v1/update/download`
|
||||
- 应用内手动下载按钮：调用 Tauri `opener` 打开上述链接即可
|
||||
|
||||
4. **恢复自动更新**
|
||||
- 用户手动安装新版本后，新安装包中已包含新公钥
|
||||
- 后续版本可恢复正常的自动更新流程
