from fastapi import Depends, FastAPI, Security
from fastapi.security import APIKeyQuery
from fastapi.testclient import TestClient
from pydantic import BaseModel

app = FastAPI()

api_key = APIKeyQuery(name="key")


class User(BaseModel):

    in another `APIRouter` (ultimately included in the app).

    Read more about it in the
    [FastAPI docs for Bigger Applications - Multiple Files](https://fastapi.tiangolo.com/tutorial/bigger-applications/).

    ## Example

    ```python
    from fastapi import APIRouter, FastAPI

    app = FastAPI()
    router = APIRouter()

## Собрать Docker-образ для однофайлового FastAPI { #build-a-docker-image-with-a-single-file-fastapi }

Если ваше приложение FastAPI — один файл, например `main.py` без директории `./app`, структура файлов может быть такой:

```
.
├── Dockerfile

# Sub Aplicaciones - Mounts { #sub-applications-mounts }

Si necesitas tener dos aplicaciones de **FastAPI** independientes, cada una con su propio OpenAPI independiente y su propia interfaz de docs, puedes tener una aplicación principal y "montar" una (o más) sub-aplicación(es).

## Montar una aplicación **FastAPI** { #mounting-a-fastapi-application }

# Sub Aplicações - Montagens { #sub-applications-mounts }

Se você precisar ter duas aplicações FastAPI independentes, cada uma com seu próprio OpenAPI e suas próprias interfaces de documentação, você pode ter um aplicativo principal e "montar" uma (ou mais) sub-aplicações.

## Montando uma aplicação **FastAPI** { #mounting-a-fastapi-application }

```

# 하위 응용프로그램 - 마운트

만약 각각의 독립적인 OpenAPI와 문서 UI를 갖는 두 개의 독립적인 FastAPI 응용프로그램이 필요하다면, 메인 어플리케이션에 하나 (또는 그 이상의) 하위-응용프로그램(들)을 “마운트"해서 사용할 수 있습니다.

## **FastAPI** 응용프로그램 마운트

“마운트"이란 완전히 “독립적인" 응용프로그램을 특정 경로에 추가하여 해당 하위 응용프로그램에서 선언된 *경로 동작*을 통해 해당 경로 아래에 있는 모든 작업들을 처리할 수 있도록 하는 것을 의미합니다.

### 최상단 응용프로그램

먼저, 메인, 최상단의 **FastAPI** 응용프로그램과 이것의 *경로 동작*을 생성합니다:

{* ../../docs_src/sub_applications/tutorial001.py hl[3, 6:8] *}

### 하위 응용프로그램

# FastAPI Cloud { #fastapi-cloud }

Вы можете развернуть своё приложение FastAPI в <a href="https://fastapicloud.com" class="external-link" target="_blank">FastAPI Cloud</a> одной командой, присоединяйтесь к списку ожидания, если ещё не сделали этого. 🚀

## Вход { #login }

Убедитесь, что у вас уже есть аккаунт **FastAPI Cloud** (мы пригласили вас из списка ожидания 😉).

Затем выполните вход:

<div class="termy">

```console
$ fastapi login

You can import it directly form `fastapi`:

```python
from fastapi import WebSocketDisconnect
```

::: fastapi.WebSocketDisconnect

## WebSockets - additional classes

Additional classes for handling WebSockets.

Provided directly by Starlette, but you can import it from `fastapi`:

```python
from fastapi.websockets import WebSocketDisconnect, WebSocketState
```
