### Normales **FastAPI**

Schreiben Sie zunächst wie gewohnt Ihre ganze **FastAPI**-Anwendung:

```Python hl_lines="1  4  7-9"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### Das OpenAPI-Schema generieren

```Python
old_dict = {
    "old key": "old value",
    "second old key": "second old value",
}
new_dict = {**old_dict, "new key": "new value"}
```

Ici, `new_dict` contiendra toutes les paires clé-valeur de `old_dict` plus la nouvelle paire clé-valeur :

```Python
{
    "old key": "old value",
    "second old key": "second old value",
    "new key": "new value",
}
```

# `HTTPConnection`-Klasse

Wenn Sie Abhängigkeiten definieren möchten, die sowohl mit HTTP als auch mit WebSockets kompatibel sein sollen, können Sie einen Parameter definieren, der eine `HTTPConnection` anstelle eines `Request` oder eines `WebSocket` akzeptiert.

Sie können diese von `fastapi.requests` importieren:

```python
from fastapi.requests import HTTPConnection
```

from fastapi.exceptions import FastAPIError
