모든 메시지는 동일한 WebSocket 연결을 사용합니다.

## `Depends` 및 기타 사용하기

WebSocket 엔드포인트에서 `fastapi`에서 다음을 가져와 사용할 수 있습니다:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

이들은 다른 FastAPI 엔드포인트/*경로 작동*과 동일하게 동작합니다:

{* ../../docs_src/websockets/tutorial002_an_py310.py hl[68:69,82] *}

/// info | 정보

{* ../../docs_src/metadata/tutorial004_py39.py hl[21,26] *}

/// info | Informação

### Cheque os documentos { #check-the-docs }

Agora, se você verificar a documentação, ela exibirá todos os metadados adicionais:

    "pydantic-settings >=2.0.0",
    # Extra Pydantic data types
    "pydantic-extra-types >=2.0.0",
]

[project.scripts]
fastapi = "fastapi.cli:main"

[tool.pdm]
version = { source = "file", path = "fastapi/__init__.py" }
distribution = true

[tool.pdm.build]
source-includes = [
    "tests/",
    "docs_src/",
    "requirements*.txt",
    "scripts/",
    # For a test

 *  </tr>
 *  <tr>
 *      <td>implementation</td>
 *      <td>none (detected)</td>
 *      <td>Yes</td>
 *      <td>The Mojo's fully-qualified class name (or script path in the case of non-Java Mojos).</td>
 *  </tr>
 *  <tr>
 *      <td>language</td>
 *      <td>none (detected)</td>
 *      <td>No. Default: <code>java</code></td>

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[9] *}

/// info | Дополнительная информация

`File` - это класс, который наследуется непосредственно от `Form`.

Но помните, что когда вы импортируете `Query`, `Path`, `File` и другие из `fastapi`, на самом деле это функции, которые возвращают специальные классы.

/// tip | Подсказка

## Verwendung von `Depends` und anderen { #using-depends-and-others }

In WebSocket-Endpunkten können Sie Folgendes aus `fastapi` importieren und verwenden:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

Diese funktionieren auf die gleiche Weise wie für andere FastAPI-Endpunkte/*Pfadoperationen*:

{* ../../docs_src/websockets/tutorial002_an_py310.py hl[68:69,82] *}

/// info | Info

    style V2 fill:#f9fff3
    style V1 fill:#fff6f0
    style V1Field fill:#fff6f0
    style V2Field fill:#f9fff3
```

In some cases, it's even possible to have both Pydantic v1 and v2 models in the same **path operation** in your FastAPI app:

{* ../../docs_src/pydantic_v1_in_v2/tutorial003_an_py310.py hl[2:3,6,12,21:22] *}

/// tip | 提示

不必为你使用的所有标签都添加元数据。

///

### 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] *}

/// info | 信息

### 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：

<img src="/img/tutorial/metadata/image02.png">

### 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。

{* ../../docs_src/query_params/tutorial006.py hl[10] *}

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.
