Щоб створити middleware, ви використовуєте декоратор `@app.middleware("http")` над функцією.

Функція middleware отримує:

* `request`.
* Функцію `call_next`, яка отримає `request` як параметр.
    * Ця функція передасть `request` відповідній *операції шляху*.
    * Потім вона поверне `response`, згенеровану відповідною *операцією шляху*.
* Потім ви можете додатково змінити `response` перед тим, як повернути її.
