Я играюсь с flask и подключением , чтобы настроить доступ к REST API для моего приложения.
Сценарий № 1: Если я запустил мое приложение с помощью инструмента запуска / отладки Pycharm Все работает нормально (приложение flask запускается, включая API из моего файла agreement_api/openapi/specification.yaml).
Сценарий № 2: Но выполняется python agreement_api/app.py ( основной скрипт, содержащий экземпляр приложения) через терминал выдает ошибку при связывании API спецификации "не существует, но поверьте мне, что это так (потому что сценарий № 1 работает нормально и нет опечаток и т. д. c) Моя структура каталогов следующая:
- Project
- соглашение_api
- контроллеры
- модели
- openapi
- app.py
- Dockerfile
- Pipfile
- Лицензия
- ...
agreement_controller.py
....
def read_agreements():
agreements = Agreement.query.order_by(Agreement.agreement_status).all()
agreement_schema = AgreementSchema(many=True)
return agreement_schema.dump(agreements), 200
....
спецификация.yaml
servers:
- url: /api
paths:
/agreement:
get:
tags:
- Agreement
summary: Read the list of agreements
description: Read the list of agreements
x-openapi-router-controller: agreement_api.controllers.agreement_controller
operationId: read_agreements
app.py
# Get the application instance
_, connexion_app = create_app()
app = connexion_app.app # Flask instance initialized by Connexion
DB = SQLAlchemy(app)
DB.create_all()
MA = Marshmallow(app)
connexion_app.add_api("specification.yaml")
(То же самое при запуске flask приложение в контейнере Docker.)
Есть ли проблема с моей структурой каталогов или мне не хватает чего-то другого? Раньше я не задавал много вопросов (это должно быть заметно по моей плохой проработке / объяснению / стилю, поэтому не стесняйтесь спрашивать меня любые подробности, если требуется)
, если кого-то интересует трассировка стека ошибок:
