# ASP.NET Core 10 迁移
|
||||||
|
|
||||||
|
迁移采用兼容优先的渐进式方案：ASP.NET Core 作为统一入口，尚未迁移的 `/api/*` 请求暂时转发给运行在 `4174` 端口的 Node.js 服务。每完成一个功能域，就在 ASP.NET Core 中注册对应原生端点并停止转发该路径。
|
||||||
|
|
||||||
|
## 当前阶段
|
||||||
|
|
||||||
|
- [x] ASP.NET Core 10 解决方案与分层项目
|
||||||
|
- [x] 原前端静态资源无修改托管
|
||||||
|
- [x] 旧 API 兼容转发，包含 Cookie、请求体、文件下载和状态码
|
||||||
|
- [x] 存活与迁移就绪检查
|
||||||
|
- [ ] 公开接口与数据库读取
|
||||||
|
- [ ] 登录、Session 与 TOTP
|
||||||
|
- [ ] 考生业务
|
||||||
|
- [ ] 管理后台、审批流和考务编排
|
||||||
|
- [ ] 招生录取
|
||||||
|
- [ ] Excel、文书和缓存
|
||||||
|
- [ ] 容器入口切换及 Node.js 后端移除
|
||||||
|
|
||||||
|
## 本地运行
|
||||||
|
|
||||||
|
先在一个终端运行旧 API：
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
$env:PORT = '4174'
|
||||||
|
npm start
|
||||||
|
```
|
||||||
|
|
||||||
|
再在另一个终端运行 ASP.NET Core 入口：
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
dotnet run --project .\src\Eis.Web\Eis.Web.csproj
|
||||||
|
```
|
||||||
|
|
||||||
|
浏览器仍访问 <http://127.0.0.1:4173>。
|
||||||
|
|
||||||
|
- `GET /health/live`：只检查 ASP.NET Core 宿主。
|
||||||
|
- `GET /health/migration`：检查迁移宿主和旧 API 转发链路。
|
||||||
|
|
||||||
|
可通过配置 `LegacyNode:Enabled=false` 禁用兼容转发；此时尚未迁移的 API 会返回 `501`。
|
||||||
|
|
||||||
|
完整的宿主、静态资源、JSON 转发和 Session Cookie 冒烟测试：
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
pwsh.exe -NoLogo -NoProfile -NonInteractive -File .\scripts\smoke-dotnet-migration.ps1
|
||||||
|
```
