# OPC UA Manager
원본 `Program.cs` (단일 파일)를 **ASP.NET Core Web API + 프론트엔드** 프로젝트로 분리한 버전입니다.
## 프로젝트 구조
```
OpcUaManager/
├── OpcUaManager.csproj
├── Program.cs ← ASP.NET Core 진입점, DI 등록
├── appsettings.json
├── init_db.sql ← PostgreSQL 테이블 초기화
│
├── Models/
│ └── Models.cs ← DTO / 도메인 모델 전체
│
├── Services/
│ ├── CertService.cs ← X.509 인증서 생성 (pki/ 폴더 체계 유지)
│ ├── OpcSessionService.cs ← OPC UA 세션 관리 (Singleton)
│ ├── OpcCrawlerService.cs ← HoneywellCrawler 로직 → Service 분리
│ └── DatabaseService.cs ← PostgreSQL 저장/조회 (SaveToDatabase 패턴 유지)
│
├── Controllers/
│ ├── CertController.cs ← POST /api/cert/generate
│ ├── SessionController.cs ← POST /api/session/connect|disconnect
│ ├── CrawlerController.cs ← POST /api/crawler/start
│ └── DatabaseController.cs ← POST /api/database/write|query|test
│
└── wwwroot/
└── index.html ← 프론트엔드 (단일 HTML, 백엔드 API 연결)
```
## 원본 코드와의 대응 관계
| 원본 코드 위치 | 분리된 위치 |
|---|---|
| `Directory.CreateDirectory("pki/...")` | `CertService.EnsurePkiDirectories()` |
| `new X509Certificate2(pfxPath, ...)` | `CertService.LoadPfx()` |
| `ApplicationConfiguration { ... }` | `OpcSessionService.ConnectAsync()` |
| `DiscoveryClient → Session.Create` | `OpcSessionService.ConnectAsync()` |
| `HoneywellCrawler.BrowseRecursiveAsync` | `OpcCrawlerService.CrawlAsync()` |
| `HoneywellCrawler.SaveToCsv` | `OpcCrawlerService.SaveToCsvAsync()` |
| `SaveToDatabase(tagName, val, status)` | `DatabaseService.SaveToDatabaseAsync()` |
| `for (int i = 0; i < 5; i++) { ... }` | `DatabaseService.WriteLoopAsync()` |
**원본 인증서 체계 유지 항목:**
- `pki/own/certs/`, `pki/trusted/certs/`, `pki/issuers/certs/`, `pki/rejected/certs/` 폴더 구조
- `X509KeyStorageFlags.Exportable | MachineKeySet`
- `AutoAcceptUntrustedCertificates = true`, `AddAppCertToTrustedStore = true`
- OPC UA SAN(Subject Alternative Name) 에 `ApplicationUri` 포함 (필수 요구사항)
## 실행 방법
### 1. PostgreSQL 초기화
```bash
createdb opcdb
psql -U postgres -d opcdb -f init_db.sql
```
### 2. 백엔드 실행
```bash
cd OpcUaManager
dotnet restore
dotnet run
# → http://localhost:5000
# → Swagger: http://localhost:5000/swagger
```
### 3. 프론트엔드 접속
브라우저에서 `http://localhost:5000` 접속
