/**
 * Helps to provide backward-compatibility with plugins that use legacy components. <strong>Warning:</strong> This is an
 * internal utility interface that is only public for technical reasons, it is not part of the public API. In
 * particular, this interface can be changed or deleted without prior notice.
 *
 * @since 3.0

Um dies zu erreichen, importieren Sie `JSONResponse`, und geben Sie Ihren Inhalt direkt zurück, indem Sie den gewünschten `status_code` setzen:

{* ../../docs_src/additional_status_codes/tutorial001_an_py310.py hl[4,25] *}

/// warning | Achtung

Wenn Sie eine `Response` direkt zurückgeben, wie im obigen Beispiel, wird sie direkt zurückgegeben.

Sie wird nicht mit einem Modell usw. serialisiert.

Чтобы добиться этого, импортируйте `JSONResponse` и верните туда свой контент напрямую, установив нужный вам `status_code`:

{* ../../docs_src/additional_status_codes/tutorial001_an_py310.py hl[4,25] *}

/// warning | Внимание

Когда вы возвращаете `Response` напрямую, как в примере выше, он будет возвращён как есть.

Он не будет сериализован с помощью модели и т.п.

与在*路径操作函数*中使用 `Query`、`Path` 、`Body` 声明校验与元数据的方式一样，可以使用 Pydantic 的 `Field` 在 Pydantic 模型内部声明校验和元数据。

## 导入 `Field`

首先，从 Pydantic 中导入 `Field`：

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}

/// warning | 警告

注意，与从 `fastapi` 导入 `Query`，`Path`、`Body` 不同，要直接从 `pydantic` 导入 `Field` 。

///

## 声明模型属性

然后，使用 `Field` 定义模型的属性：

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

 * should override one or more methods to modify the behavior of the backing multiset as desired per
 * the <a href="http://en.wikipedia.org/wiki/Decorator_pattern">decorator pattern</a>.
 *
 * <p><b>Warning:</b> The methods of {@code ForwardingSortedMultiset} forward
 * <b>indiscriminately</b> to the methods of the delegate. For example, overriding {@link

    return newReentrantLock(lockName, false);
  }

  /**
   * Creates a {@link ReentrantLock} with the given fairness policy. The {@code lockName} is used in
   * the warning or exception output to help identify the locks involved in the detected deadlock.
   */
  public ReentrantLock newReentrantLock(String lockName, boolean fair) {
    return policy == Policies.DISABLED

## 定义 `File` 与 `Form` 参数

创建文件和表单参数的方式与 `Body` 和 `Query` 一样：

{* ../../docs_src/request_forms_and_files/tutorial001.py hl[8] *}

文件和表单字段作为表单数据上传与接收。

声明文件可以使用 `bytes` 或 `UploadFile` 。

/// warning | 警告

可在一个*路径操作*中声明多个 `File` 与 `Form` 参数，但不能同时声明要接收 JSON 的 `Body` 字段。因为此时请求体的编码为 `multipart/form-data`，不是 `application/json`。

这不是 **FastAPI** 的问题，而是 HTTP 协议的规定。
