## Instalando `WebSockets`

Garanta que você criou um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, o ativou e instalou o `websockets`:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## Cliente WebSockets

### Em produção

<div class="termy">

```console
$ python myapp.py
```

</div>

mais qui n'est pas appelé lorsqu'un autre fichier l'importe, comme dans :

```Python
from myapp import app
```

#### Pour davantage de détails

Imaginons que votre fichier s'appelle `myapp.py`.

Si vous l'exécutez avec :

<div class="termy">

```console
$ python myapp.py
```

Agora inicie o Traefik:

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

E agora inicie sua aplicação, usando a opção `--root-path`:

<div class="termy">

```console
$ fastapi run main.py --root-path /api/v1

# Pierwsze kroki

Najprostszy plik FastAPI może wyglądać tak:

{* ../../docs_src/first_steps/tutorial001.py *}

Skopiuj to do pliku `main.py`.

Uruchom serwer:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]

## Instalar o `SQLModel`

Primeiro, certifique-se de criar seu [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo e, em seguida, instalar o `sqlmodel`:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>

## Criar o App com um Único Modelo

Vamos criar a primeira versão mais simples do app com um único modelo **SQLModel**.

每個部分都是在前一部分的基礎上逐步建置的，但內容結構是按主題分開的，因此你可以直接跳到任何特定的部分，解決你具體的 API 需求。

它也被設計成可作為未來的參考，讓你隨時回來查看所需的內容。

## 運行程式碼

所有程式碼區塊都可以直接複製和使用（它們實際上是經過測試的 Python 檔案）。

要運行任何範例，請將程式碼複製到 `main.py` 檔案，並使用以下命令啟動 `fastapi dev`：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

Now start Traefik:

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

And now start your app, using the `--root-path` option:

<div class="termy">

```console
$ fastapi run main.py --root-path /api/v1

Make sure you create a [virtual environment](../../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info

And then we use it when creating the `FastAPI` app.

Then you could disable OpenAPI (including the UI docs) by setting the environment variable `OPENAPI_URL` to the empty string, like:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

```Python
{!../../docs_src/async_tests/test_main.py!}
```

## Es ausführen

Sie können Ihre Tests wie gewohnt ausführen mit:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>
