다음과 같이 임포트하셔도 좋습니다. `from starlette import status`.

**FastAPI**는 개발자 여러분의 편의를 위해 `starlette.status`와 동일한 `fastapi.status`를 제공합니다. 하지만 이는 Starlette에서 직접 온 것입니다.

## 태그 { #tags }

(보통 단일 `str`인) `str`로 구성된 `list`와 함께 매개변수 `tags`를 전달하여, *경로 처리*에 태그를 추가할 수 있습니다:

{* ../../docs_src/path_operation_configuration/tutorial002_py310.py hl[15,20,25] *}

전달된 태그들은 OpenAPI의 스키마에 추가되며, 자동 문서 인터페이스에서 사용됩니다:

# 直接回傳 Response { #return-a-response-directly }

當你建立一個 **FastAPI** 的路徑操作 (path operation) 時，通常可以從中回傳任何資料：`dict`、`list`、Pydantic 模型、資料庫模型等。

如果你宣告了 [回應模型](../tutorial/response-model.md)，FastAPI 會用 Pydantic 將資料序列化為 JSON。

如果你沒有宣告回應模型，FastAPI 會使用在[JSON 相容編碼器](../tutorial/encoder.md)中說明的 `jsonable_encoder`，並把它放進 `JSONResponse`。

但你也可以直接從路徑操作回傳 `JSONResponse`。

/// tip

    ...
```

...o prefixo não deve incluir um `/` final.

Então, o prefixo neste caso é `/items`.

Também podemos adicionar uma list de `tags` e `responses` extras que serão aplicadas a todas as *operações de rota* incluídas neste router.

E podemos adicionar uma list de `dependencies` que serão adicionadas a todas as *operações de rota* no router e serão executadas/resolvidas para cada request feita a elas.

/// tip | Dica

pkg container/list, method (*List) Len() int
pkg container/list, method (*List) MoveToBack(*Element)
pkg container/list, method (*List) MoveToFront(*Element)
pkg container/list, method (*List) PushBack(interface{}) *Element
pkg container/list, method (*List) PushBackList(*List)
pkg container/list, method (*List) PushFront(interface{}) *Element
pkg container/list, method (*List) PushFrontList(*List)

Sie könnten ein `dict`, eine `list`, usw. übergeben.

Diese werden von **FastAPI** automatisch gehandhabt und in JSON konvertiert.

## Benutzerdefinierte Header hinzufügen { #add-custom-headers }

Es gibt Situationen, in denen es nützlich ist, dem HTTP-Error benutzerdefinierte Header hinzuzufügen. Zum Beispiel in einigen Sicherheitsszenarien.

        HttpUrl::class.java to url,
        IOException::class.java to IOException("boom"),
        InetSocketAddress::class.java to InetSocketAddress.createUnresolved("localhost", 80),
        List::class.java to listOf<Any?>(),
        Long::class.java to 123L,
        Protocol::class.java to Protocol.HTTP_2,
        Proxy::class.java to Proxy.NO_PROXY,
        Request::class.java to request,

Verwenden Sie nun den Parameter `callbacks` im *Pfadoperation-Dekorator Ihrer API*, um das Attribut `.routes` (das ist eigentlich nur eine `list`e von Routen/*Pfadoperationen*) dieses Callback-Routers zu übergeben:

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[33] *}

/// tip | Tipp

    }

    @Test
    public void test_inheritance() {
        DocList docList = new DocList();

        assertTrue(docList instanceof java.util.ArrayList);
        assertTrue(docList instanceof java.util.List);
        assertTrue(docList instanceof java.util.Collection);
    }

/// note | 技术细节

也可以使用 `from starlette import status` 导入状态码。

**FastAPI** 提供的 `fastapi.status` 与 `starlette.status` 相同，方便你作为开发者使用。实际上它直接来自 Starlette。

## 标签 { #tags }

可以通过传入由 `str` 组成的 `list`（通常只有一个 `str`）的参数 `tags`，为*路径操作*添加标签：

{* ../../docs_src/path_operation_configuration/tutorial002_py310.py hl[15,20,25] *}

OpenAPI 概图会自动添加标签，供 API 文档接口使用：

  /** The lock underlying this monitor. */
  private final ReentrantLock lock;

  /**
   * The guards associated with this monitor that currently have waiters ({@code waiterCount > 0}).
   * A linked list threaded through the Guard.next field.
   */
  @GuardedBy("lock")
  private @Nullable Guard activeGuards = null;

  /**
   * Creates a monitor with a non-fair (but fast) ordering policy. Equivalent to {@code
