{* ../../docs_src/additional_responses/tutorial003_py39.py hl[20:31] *}

Всё это будет объединено и включено в ваш OpenAPI и отображено в документации API:

<img src="/img/tutorial/additional-responses/image01.png">

## Комбинирование предопределённых и пользовательских ответов { #combine-predefined-responses-and-custom-ones }

{* ../../docs_src/security/tutorial006_an_py39.py hl[4,8,12] *}

When you try to open the URL for the first time (or click the "Execute" button in the docs) the browser will ask you for your username and password:

<img src="/img/tutorial/security/image12.png">

## Check the username { #check-the-username }

Here's a more complete example.

Use a dependency to check if the username and password are correct.

{* ../../docs_src/security/tutorial006_an_py39.py hl[4,8,12] *}

Cuando intentas abrir la URL por primera vez (o haces clic en el botón "Execute" en la documentación) el navegador te pedirá tu nombre de usuario y contraseña:

<img src="/img/tutorial/security/image12.png">

## Revisa el nombre de usuario { #check-the-username }

Aquí hay un ejemplo más completo.

Usa una dependencia para comprobar si el nombre de usuario y la contraseña son correctos.

    page.get_by_role("button", name="GET /items/ Read Items").click()
    page.get_by_role("button", name="Try it out").click()
    # Manually add the screenshot
    page.screenshot(path="docs/en/docs/img/tutorial/header-param-models/image01.png")

    # ---------------------
    context.close()
    browser.close()


process = subprocess.Popen(
    ["fastapi", "run", "docs_src/header_param_models/tutorial001.py"]

    page.get_by_role("button", name="POST /login/ Login").click()
    page.get_by_role("button", name="Try it out").click()
    # Manually add the screenshot
    page.screenshot(path="docs/en/docs/img/tutorial/request-form-models/image01.png")

    # ---------------------
    context.close()
    browser.close()


process = subprocess.Popen(
    ["fastapi", "run", "docs_src/request_form_models/tutorial001.py"]

And you will be able to select which scopes you want to give access to: `me` and `items`.

This is the same mechanism used when you give permissions while logging in with Facebook, Google, GitHub, etc:

<img src="/img/tutorial/security/image11.png">

## JWT token with scopes { #jwt-token-with-scopes }

Now, modify the token *path operation* to return the scopes requested.

### 現代 Python

這一切都基於標準的 **Python 型別**宣告（感謝 Pydantic）。無需學習新的語法，只需使用標準的現代 Python。

Вы увидите документацию, включающую раздел «Callbacks» для вашей *операции пути*, который показывает, как должен выглядеть *внешний API*:

Vous verrez la documentation interactive automatique de l'API (fournie par <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>) :

## Documentation de l'API alternative

Und Sie können auswählen, auf welche Scopes Sie Zugriff haben möchten: `me` und `items`.

Das ist derselbe Mechanismus, der verwendet wird, wenn Sie beim Anmelden mit Facebook, Google, GitHub, usw. Berechtigungen erteilen:

<img src="/img/tutorial/security/image11.png">

## JWT-Token mit Scopes { #jwt-token-with-scopes }

Ändern Sie nun die Token-*Pfadoperation*, um die angeforderten Scopes zurückzugeben.
