## WebSockets-Client { #websockets-client }

### In Produktion { #in-production }

FastAPI 0.126.0 dropped support for Pydantic v1, while still supporting `pydantic.v1` for a little while.

/// warning

The Pydantic team stopped support for Pydantic v1 for the latest versions of Python, starting with **Python 3.14**.

This includes `pydantic.v1`, which is no longer supported in Python 3.14 and above.

<div class="termy">

```console
$ python myapp.py

```Python

#### Weitere Details { #more-details }

Angenommen, Ihre Datei heißt `myapp.py`.

Wenn Sie sie mit folgendem Befehl ausführen:

<div class="termy">

```console
$ python myapp.py

app = FastAPI(
    title="ChimichangApp",
    description=description,
    summary="Deadpool's favorite app. Nuff said.",
    version="0.0.1",
    terms_of_service="http://example.com/terms/",
    contact={

        "email": "******@****.***",
    },
    license_info={
        "name": "Apache 2.0",

All the code blocks can be copied and used directly (they are actually tested Python files).

To run any of the examples, copy the code to a file `main.py`, and start `fastapi dev` with:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:solid">main.py</u>

Убедитесь, что вы создали [виртуальное окружение](../virtual-environments.md){.internal-link target=_blank}, активировали его и установили `websockets` (библиотека Python, упрощающая работу с протоколом "WebSocket"):

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## Клиент WebSockets { #websockets-client }

### В продакшн { #in-production }

E esse é o mesmo nível de performance que você tem com o **FastAPI**.

Pour exécuter l'un de ces exemples, copiez le code dans un fichier `main.py`, et commencez `uvicorn` avec :

<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)
