# ============================================================================
# ANTOOZA Postman Collection 갱신 스크립트
#
# 사용법:
#   1. 백엔드 실행 (다른 터미널)
#      cd E:\workspace\antooza\Backend
#      dotnet run --project Web.Api
#
#   2. 이 스크립트 실행
#      cd E:\workspace\antooza\Backend\Web.Api\postman
#      pwsh ./update.ps1
#
# 옵션:
#   -ApiBase   <url>   기본값: https://localhost:4000
#   -SkipInternal      internal swagger 변환 생략
#
# 결과:
#   collections/ANTOOZA-Internal-API.postman_collection.json (내부 /api/*)
#
# 요구사항:
#   - Node.js (npx 포함) — openapi-to-postmanv2 를 npx 로 1회성 실행
#   - 실행 중인 로컬 백엔드 (internal swagger 는 Production 에 차단되어 로컬 필수)
