### 4.2 配置环境变量
在 Azure Key Vault 中创建以下 secrets:
#### 全局 Secrets
| Secret Name | 说明 |
|-------------|------|
| `db-password` | PostgreSQL 密码 |
| `jwt-secret` | JWT 签名密钥 |
| `encryption-key` | AES-256 加密密钥 |
| `ocr-api-key` | Invoice Master API Key |
#### Provider-Specific Secrets
| Secret Name | 说明 | 状态 |
|-------------|------|------|
| `fortnox-client-id` | Fortnox OAuth Client ID | Required |
| `fortnox-client-secret` | Fortnox OAuth Client Secret | Required |
| `fortnox-redirect-uri` | Fortnox OAuth Redirect URI | Required |
| `visma-client-id` | Visma OAuth Client ID | Future |
| `visma-client-secret` | Visma OAuth Client Secret | Future |
| `visma-redirect-uri` | Visma OAuth Redirect URI | Future |
```bash
# 示例: 添加 global secrets
az keyvault secret set --vault-name kv-invoice-master-prod \
--name "jwt-secret" \
--value "your-256-bit-secret-key-here"
# 示例: 添加 Fortnox secrets
az keyvault secret set --vault-name kv-invoice-master-prod \
--name "fortnox-client-id" \
--value "your-fortnox-client-id"
az keyvault secret set --vault-name kv-invoice-master-prod \
--name "fortnox-client-secret" \
--value "your-fortnox-client-secret"
```
### 4.3 部署到 Container Apps
```bash
# 更新后端应用

--connection "Host=psql-invoice-master-prod.postgres.database.azure.com;Database=invoice_master;Username=dbadmin;Password=$DB_PASSWORD"
# 生成 SQL 脚本 (生产环境推荐)
dotnet ef migrations script \
--startup-project ../InvoiceMaster.API \
--output migration.sql
# 执行 SQL 脚本
psql "Host=psql-invoice-master-prod.postgres.database.azure.com;Database=invoice_master;Username=dbadmin" \
-f migration.sql
```
#### 4.4.1 生产环境迁移最佳实践
```bash
# 使用临时 Container App Job 运行迁移
az containerapp job create \
--name db-migration-job \
--resource-group rg-invoice-master-prod \
--environment cae-invoice-master-prod \
--image {acr-name}.azurecr.io/invoice-master-api:v1.0.0 \
