# Middleware (Проміжний шар)

У **FastAPI** можна додавати middleware (проміжний шар).

"Middleware" — це функція, яка працює з кожним **запитом** перед його обробкою будь-якою конкретною *операцією шляху* (*path operation*), а також з кожною **відповіддю** перед її поверненням.

* Middleware отримує кожен **запит**, що надходить до Вашого застосунку.
* Може виконати певні дії із цим **запитом** або запустити необхідний код.

/// tip

You can set a dependency override for a dependency used anywhere in your **FastAPI** application.

The original dependency could be used in a *path operation function*, a *path operation decorator* (when you don't use the return value), a `.include_router()` call, etc.

FastAPI will still be able to override it.

///

Let's imagine you want to get the client's IP address/host inside of your *path operation function*.

For that you need to access the request directly.

{* ../../docs_src/using_request_directly/tutorial001.py hl[1,7:8] *}

By declaring a *path operation function* parameter with the type being the `Request` **FastAPI** will know to pass the `Request` in that parameter.

/// tip

En este caso, este `__call__` es lo que **FastAPI** usará para comprobar parámetros adicionales y sub-dependencias, y es lo que llamará para pasar un valor al parámetro en tu *path operation function* más adelante.

## Parametrizar la instance

Y ahora, podemos usar `__init__` para declarar los parámetros de la instance que podemos usar para "parametrizar" la dependencia:

# Body - Fields { #body-fields }

The same way you can declare additional validation and metadata in *path operation function* parameters with `Query`, `Path` and `Body`, you can declare validation and metadata inside of Pydantic models using Pydantic's `Field`.

## Import `Field` { #import-field }

First, you have to import it:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}
