/// info | Info

Der Parameter `response_class` wird auch verwendet, um den „Medientyp“ der Response zu definieren.

The function parameters will be recognized as follows:

* If the parameter is also declared in the **path**, it will be used as a path parameter.
* If the parameter is of a **singular type** (like `int`, `float`, `str`, `bool`, etc) it will be interpreted as a **query** parameter.
* If the parameter is declared to be of the type of a **Pydantic model**, it will be interpreted as a request **body**.

# Pfad-Parameter und Validierung von Zahlen { #path-parameters-and-numeric-validations }

So wie Sie mit `Query` für Query-Parameter zusätzliche Validierungen und Metadaten deklarieren können, können Sie mit `Path` die gleichen Validierungen und Metadaten für Pfad-Parameter deklarieren.

## `Path` importieren { #import-path }

Importieren Sie zuerst `Path` von `fastapi`, und importieren Sie `Annotated`:

Você também pode adicionar metadados adicionais para as diferentes tags usadas para agrupar suas operações de rota com o parâmetro `openapi_tags`.

Ele recebe uma lista contendo um dicionário para cada tag.

Cada dicionário pode conter:

* `name` (**obrigatório**): uma `str` com o mesmo nome da tag que você usa no parâmetro `tags` nas suas *operações de rota* e `APIRouter`s.
