# Request Files { #request-files }

You can define files to be uploaded by the client using `File`.

/// info

To receive uploaded files, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console

///

/// warning

You can declare multiple `Form` parameters in a *path operation*, but you can't also declare `Body` fields that you expect to receive as JSON, as the request will have the body encoded using `application/x-www-form-urlencoded` instead of `application/json`.

This is not a limitation of **FastAPI**, it's part of the HTTP protocol.

## Details about the `Request` object { #details-about-the-request-object }

As **FastAPI** is actually **Starlette** underneath, with a layer of several tools on top, you can use Starlette's <a href="https://www.starlette.io/requests/" class="external-link" target="_blank">`Request`</a> object directly when you need to.

**FastAPI** will **extract** the data for **each field** from the **form data** in the request and give you the Pydantic model you defined.
