<1> Parameters in the parameter type must be annotated. If a parameter is annotated with link:{javadocPath}/org/gradle/api/services/ServiceReference.html[`@ServiceReference`], then a suitable shared build service implementation is automatically assigned to the parameter when the action is created, according to the <<build_services.adoc#sec:service_references,usual rules>>.

# Request-Parameter

Hier die Referenzinformationen für die Request-Parameter.

Dies sind die Sonderfunktionen, die Sie mittels `Annotated` in *Pfadoperation-Funktion*-Parameter oder Abhängigkeitsfunktionen einfügen können, um Daten aus dem Request abzurufen.

Dies beinhaltet:

* `Query()`
* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

Sie können diese alle direkt von `fastapi` importieren:

```python

# Request Parameters

Here's the reference information for the request parameters.

These are the special functions that you can put in *path operation function* parameters or dependency functions with `Annotated` to get data from the request.

It includes:

* `Query()`
* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

You can import them all directly from `fastapi`:
