Если хотите узнать больше об HTTPS, смотрите руководство [О HTTPS](../deployment/https.md){.internal-link target=_blank}.

### Как работают пересылаемые заголовки прокси { #how-proxy-forwarded-headers-work }

Ниже показано, как прокси добавляет пересылаемые заголовки между клиентом и сервером приложения:

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und es dann installieren, zum Beispiel:

```console
$ pip install email-validator
```

oder mit:

```console
$ pip install "pydantic[email]"
```

///

Primero, echemos un vistazo rápido a las partes que cambian desde los ejemplos en el **Tutorial - User Guide** principal para [OAuth2 con Password (y hashing), Bearer con tokens JWT](../../tutorial/security/oauth2-jwt.md){.internal-link target=_blank}. Ahora usando scopes de OAuth2:

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,9,13,47,65,106,108:116,122:126,130:136,141,157] *}

Ahora revisemos esos cambios paso a paso.

## `websockets` installieren { #install-websockets }

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und `websockets` installieren (eine Python-Bibliothek, die die Verwendung des „WebSocket“-Protokolls erleichtert):

<div class="termy">

```console
$ pip install websockets

You can read it to understand better what has changed.

## Tests { #tests }

Make sure you have [tests](../tutorial/testing.md){.internal-link target=_blank} for your app and you run them on continuous integration (CI).

This way, you can do the upgrade and make sure everything is still working as expected.

## `bump-pydantic` { #bump-pydantic }

在大多數情況下，你會（也應該）有一個「終止代理」來處理 HTTPS，這取決於你如何部署你的應用程式，你的服務供應商可能會為你做這件事，或者你需要自己設置它。

你可以在[部署文件](deployment/index.md){.internal-link target=_blank}中了解更多相關資訊。

### 使用你的标签

将 `tags` 参数和*路径操作*（以及 `APIRouter`）一起使用，将其分配给不同的标签：

{* ../../docs_src/metadata/tutorial004.py hl[21,26] *}

### 查看文档

如果你现在查看文档，它们会显示所有附加的元数据：

### 标签顺序

每个标签元数据字典的顺序也定义了在文档用户界面显示的顺序。

위 예시에서는 3가지 쿼리 매개변수가 있습니다:

* `needy`, 필수적인 `str`.
* `skip`, 기본값이 `0`인 `int`.
* `limit`, 선택적인 `int`.

/// tip | 팁

[경로 매개변수](path-params.md#_8){.internal-link target=_blank}와 마찬가지로 `Enum`을 사용할 수 있습니다.
