You can return it directly.

It accepts the following parameters:

* `content` - A `str` or `bytes`.
* `status_code` - An `int` HTTP status code.
* `headers` - A `dict` of strings.
* `media_type` - A `str` giving the media type. E.g. `"text/html"`.

FastAPI (actually Starlette) will automatically include a Content-Length header. It will also include a Content-Type header, based on the `media_type` and appending a charset for text types.

In the previous chapter the security system (which is based on the dependency injection system) was giving the *path operation function* a `token` as a `str`:

{* ../../docs_src/security/tutorial001_an_py310.py hl[12] *}

But that is still not that useful.

Let's make it give us the current user.

## Create a user model { #create-a-user-model }

First, let's create a Pydantic user model.

    * Changes in docs. This includes updating the docs, fixing typos. But it doesn't include changes to translations.
    * You can normally quickly detect it by going to the "Files changed" tab in the PR and checking if the updated file(s) starts with `docs/en/docs`. The original version of the docs is always in English, so in `docs/en/docs`.

I used to say I didn't like history that much... and look at me now giving "tech history" lessons. 😅
