# Middleware

There are several middlewares available provided by Starlette directly.

Read more about them in the [FastAPI docs for Middleware](https://fastapi.tiangolo.com/advanced/middleware/).

::: fastapi.middleware.cors.CORSMiddleware

It can be imported from `fastapi`:

```python
from fastapi.middleware.cors import CORSMiddleware
```

::: fastapi.middleware.gzip.GZipMiddleware

It can be imported from `fastapi`:

/// note | Technical Details

You could also use `from starlette.middleware.cors import CORSMiddleware`.

**FastAPI** provides several middlewares in `fastapi.middleware` just as a convenience for you, the developer. But most of the available middlewares come directly from Starlette.

/// note | Detalhes técnicos

Você também pode usar `from starlette.middleware.cors import CORSMiddleware`.

**FastAPI** fornece vários middlewares em `fastapi.middleware` apenas como uma conveniência para você, o desenvolvedor. Mas a maioria dos middlewares disponíveis vêm diretamente da Starlette.

`FastAPI` is a Python class that provides all the functionality for your API.

/// note | Technical Details

`FastAPI` is a class that inherits directly from `Starlette`.

You can use all the <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> functionality with `FastAPI` too.

### Step 2: create a `FastAPI` "instance" { #step-2-create-a-fastapi-instance }

Néanmoins, cela reste faisable dans **FastAPI**, via les outils internes de Starlette.

Et la documentation fonctionne quand même, bien qu'aucune section ne soit ajoutée pour dire que la paramètre devrait contenir un *chemin*.

### Convertisseur de *chemin*

En utilisant une option de Starlette directement, vous pouvez déclarer un *paramètre de chemin* contenant un *chemin* avec une URL comme :

```

Тем не менее это можно сделать в **FastAPI**, используя один из внутренних инструментов Starlette.

Документация по-прежнему будет работать, хотя и не добавит никакой информации о том, что параметр должен содержать путь.

### Конвертер пути

Благодаря одной из опций Starlette, можете объявить *параметр пути*, содержащий *путь*, используя URL вроде:

```
/files/{file_path:path}
```
