شما می‌توانید کدی را برای اجرا با `درخواست`، قبل از اینکه هر *path operation* آن را دریافت کند، اضافه کنید.

همچنین پس از تولید `پاسخ`، قبل از بازگشت آن، می‌توانید کدی را اضافه کنید.

به عنوان مثال، می‌توانید یک هدر سفارشی به نام `X-Process-Time` که شامل زمان پردازش درخواست و تولید پاسخ به صورت ثانیه است، اضافه کنید.

```Python hl_lines="10  12-13"
{!../../docs_src/middleware/tutorial001.py!}
```

E também depois que a `response` é gerada, antes de retorná-la.

Por exemplo, você pode adicionar um cabeçalho personalizado `X-Process-Time` contendo o tempo em segundos que levou para processar a solicitação e gerar uma resposta:
