Mas se acessarmos a interface de documentação no URL "oficial" usando o proxy com a porta `9999`, em `/api/v1/docs`, ela funciona corretamente! 🎉

Você pode verificar em <a href="http://127.0.0.1:9999/api/v1/docs" class="external-link" target="_blank">http://127.0.0.1:9999/api/v1/docs</a>:

Exatamente como queríamos. ✔️

Verwenden Sie die Anmeldedaten:

Benutzer: `johndoe`

Passwort: `secret`.

<img src="/img/tutorial/security/image04.png">

Nach der Authentifizierung im System sehen Sie Folgendes:

### Die eigenen Benutzerdaten ansehen

Verwenden Sie nun die Operation `GET` mit dem Pfad `/users/me`.

Sie erhalten Ihre Benutzerdaten:

### Gewoon Moderne Python

可以看到如下用户界面：

<img src="https://fastapi.tiangolo.com/img/tutorial/security/image07.png">

用与上一章同样的方式实现应用授权。

使用如下凭证：

用户名: `johndoe` 密码: `secret`

/// check | "检查"

注意，代码中没有明文密码**`secret`**，只保存了它的哈希值。

///

<img src="https://fastapi.tiangolo.com/img/tutorial/security/image08.png">

调用 `/users/me/` 端点，收到下面的响应：

```JSON
{
  "username": "johndoe",

<img src="/img/tutorial/path-params/image01.png">

/// check | "Заметка"

Ещё раз, просто используя определения типов, **FastAPI** обеспечивает автоматическую интерактивную документацию (с интеграцией Swagger UI).

![Events Diagram](../assets/images/events@2x.png)

Here’s a [sample event listener](https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/PrintEventsNonConcurrent.java) that prints each event with a timestamp.

```java

Sie können beispielsweise einen zusätzlichen Medientyp `image/png` hinzufügen und damit deklarieren, dass Ihre *Pfadoperation* ein JSON-Objekt (mit dem Medientyp `application/json`) oder ein PNG-Bild zurückgeben kann:

```Python hl_lines="19-24  28"
{!../../docs_src/additional_responses/tutorial002.py!}
```

/// note | "Hinweis"

You can use this same `responses` parameter to add different media types for the same main response.

For example, you can add an additional media type of `image/png`, declaring that your *path operation* can return a JSON object (with media type `application/json`) or a PNG image:

{* ../../docs_src/additional_responses/tutorial002.py hl[19:24,28] *}

/// note

Notice that you have to return the image using a `FileResponse` directly.
