# WSGI 포함하기 - Flask, Django 등 { #including-wsgi-flask-django-others }

[서브 애플리케이션 - 마운트](sub-applications.md), [프록시 뒤에서](behind-a-proxy.md)에서 본 것처럼 WSGI 애플리케이션을 마운트할 수 있습니다.

이를 위해 `WSGIMiddleware`를 사용해 WSGI 애플리케이션(예: Flask, Django 등)을 감쌀 수 있습니다.

## `WSGIMiddleware` 사용하기 { #using-wsgimiddleware }

/// info | 정보

이를 사용하려면 `a2wsgi`를 설치해야 합니다. 예: `pip install a2wsgi`

///

`a2wsgi`에서 `WSGIMiddleware`를 import 해야 합니다.

以上述方式挂载子应用时，FastAPI 使用 ASGI 规范中的 `root_path` 机制处理挂载子应用路径之间的通信。

这样，子应用就可以为自动文档使用路径前缀。

并且子应用还可以再挂载子应用，一切都会正常运行，FastAPI 可以自动处理所有 `root_path`。

Если вы запускаете контейнер за прокси-сервером TSL-терминации (балансировщиком нагрузки), таким как Nginx или Traefik, добавьте опцию `--proxy-headers`. Это сообщит Uvicorn (через FastAPI CLI), что приложение работает за HTTPS и можно доверять соответствующим заголовкам.
