```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

Da `description` und `tax` optional sind (mit `None` als Defaultwert), wäre folgendes JSON „`object`“ auch gültig:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

Angenommen, Sie haben eine *Pfadoperation* mit einem Pfad `/files/{file_path}`.

Aber `file_path` soll selbst einen *Pfad* enthalten, etwa `home/johndoe/myfile.txt`.

Sprich, die URL für diese Datei wäre etwas wie: `/files/home/johndoe/myfile.txt`.

### OpenAPI-Unterstützung { #openapi-support }

Wenn Sie beispielsweise eine Datenbanksession in einer Abhängigkeit mit `yield` hatten, konnte die `StreamingResponse` diese Session während des Streamens von Daten nicht verwenden, weil die Session im Exit-Code nach `yield` bereits geschlossen worden wäre.

It is also built to work as a future reference so you can come back and see exactly what you need.

## Run the code { #run-the-code }

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

	}
	ps.Lock()
	defer ps.Unlock()

	sub := &Sub[T]{ch: subCh, types: Mask(mask.Mask()), filter: filter}
	ps.subs = append(ps.subs, sub)

	// We hold a lock, so we are safe to update
	combined := Mask(atomic.LoadUint64(&ps.types))
	combined.Merge(Mask(mask.Mask()))
	atomic.StoreUint64(&ps.types, uint64(combined))

	go func() {
		<-doneCh

		ps.Lock()
		defer ps.Unlock()
