/// info | Technical Details

`Security` is actually a subclass of `Depends`, and it has just one extra parameter that we'll see later.

But by using `Security` instead of `Depends`, **FastAPI** will know that it can declare security scopes, use them internally, and document the API with OpenAPI.

     * to be passed to the readXxxWireFormat methods. This is
     * actually purer. However, in the case of smb we know the
     * wordCount and byteCount. And since every subclass of
     * ServerMessageBlock would have to perform the same read
     * operation on the input stream, we might as will pull that
     * common functionality into the superclass and read wordCount

* 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

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:

{* ../../docs_src/response_model/tutorial003_03_py310.py hl[8:9] *}

І інструменти також будуть задоволені, бо і `RedirectResponse`, і `JSONResponse` є підкласами `Response`, отже анотація типу коректна.

### Анотувати підклас Response { #annotate-a-response-subclass }

Ви також можете використати підклас `Response` в анотації типу:

{* ../../docs_src/response_model/tutorial003_03_py310.py hl[8:9] *}
