在这个示例中，我们没有声明任何 Pydantic 模型。事实上，请求体甚至没有被 <dfn title="从某种纯文本格式（如字节）转换为 Python 对象">解析</dfn> 为 JSON，而是直接以 `bytes` 读取，并由函数 `magic_data_reader()` 以某种方式负责解析。

尽管如此，我们仍然可以声明请求体的预期方案。

### 自定义 OpenAPI 内容类型 { #custom-openapi-content-type }

使用同样的技巧，你可以用一个 Pydantic 模型来定义 JSON Schema，然后把它包含到该 *路径操作* 的自定义 OpenAPI 方案部分中。

即使请求中的数据类型不是 JSON，你也可以这样做。

# Concepts de déploiement { #deployments-concepts }

Lorsque vous déployez une application **FastAPI**, ou en fait n'importe quel type de web API, il existe plusieurs concepts qui vous importent probablement, et en les utilisant vous pouvez trouver la manière la **plus appropriée** de **déployer votre application**.

Parmi les concepts importants, on trouve :

* Sécurité - HTTPS
* Exécuter au démarrage
* Redémarrages

`Annotated`를 사용하기 전에 최소 0.95.1 버전으로 [FastAPI 버전 업그레이드](../deployment/versions.md#upgrading-the-fastapi-versions)를 진행하세요.

///

## `q` 매개변수의 타입에 `Annotated` 사용하기 { #use-annotated-in-the-type-for-the-q-parameter }

이전에 [Python 타입 소개](../python-types.md#type-hints-with-metadata-annotations)에서 `Annotated`를 사용해 매개변수에 메타데이터를 추가할 수 있다고 말씀드린 것을 기억하시나요?

이제 FastAPI에서 사용할 차례입니다. 🚀

다음과 같은 타입 어노테이션이 있었습니다:

```Python
q: str | None = None

     * @throws DcerpcException
     * @throws NdrException
     */
    private byte[] receiveMoreFragments(final DcerpcMessage msg, byte[] in) throws IOException, DcerpcException, NdrException {
        int off = msg.ptype == 2 ? msg.length : 24;
        final byte[] fragBytes = new byte[this.max_recv];
        final NdrBuffer fragBuf = new NdrBuffer(fragBytes, 0);
        while (!msg.isFlagSet(DCERPC_LAST_FRAG)) {

   * directly, use {@link MinMaxPriorityQueue#orderedBy(Comparator)}, {@link
   * MinMaxPriorityQueue#expectedSize(int)} or {@link MinMaxPriorityQueue#maximumSize(int)}.
   *
   * @param <B> the upper bound on the eventual type that can be produced by this builder (for
   *     example, a {@code Builder<Number>} can produce a {@code Queue<Number>} or {@code
   *     Queue<Integer>} but not a {@code Queue<Object>}).
   * @since 8.0
