E as ferramentas também ficarão felizes porque `RedirectResponse` e ​​`JSONResponse` são subclasses de `Response`, então a anotação de tipo está correta.

### Anote uma subclasse de Response { #annotate-a-response-subclass }

Você também pode usar uma subclasse de `Response` na anotação de tipo:

* to handle

* the model
* the Pydantic model
* the data model
* the database model
* the form model
* the model object

* the class
* the base class
* the parent class
* the subclass
* the child class
* the sibling class
* the class method

* the header
* the headers
* the authorization header
* the `Authorization` header
* the forwarded header

* event handler
* exception handler
* handle etmek

* model
* Pydantic model
* data model
* database model
* form model
* model object

* class
* base class
* parent class
* subclass
* child class
* sibling class
* class method

* header
* headers
* authorization header
* `Authorization` header
* forwarded header

* dependency injection system
* dependency

    }

 * a lot of busy work, and the annotation matters only when the APIs to be annotated are visible to

Y las herramientas también estarán felices porque tanto `RedirectResponse` como `JSONResponse` son subclases de `Response`, por lo que la anotación del tipo es correcta.

### Anotar una Subclase de Response { #annotate-a-response-subclass }

También puedes usar una subclase de `Response` en la anotación del tipo:

Bu basit durum FastAPI tarafından otomatik olarak ele alınır; çünkü dönüş tipi annotation’ı `Response` class’ıdır (veya onun bir subclass’ı).

Araçlar da memnun olur; çünkü hem `RedirectResponse` hem `JSONResponse`, `Response`’un subclass’ıdır. Yani type annotation doğrudur.

### Bir Response Subclass’ını Annotate Etmek { #annotate-a-response-subclass }

Type annotation içinde `Response`’un bir subclass’ını da kullanabilirsiniz:
