#### *Enumeration Üyelerini* Döndürelim

JSON gövdesine (örneğin bir `dict`) gömülü olsalar bile *yol operasyonundaki* *enum üyelerini* döndürebilirsiniz.

Bu üyeler istemciye iletilmeden önce kendilerine karşılık gelen değerlerine (bu durumda string) dönüştürüleceklerdir:

```Python hl_lines="18  21  23"
{!../../docs_src/path_params/tutorial005.py!}
```

İstemci tarafında şuna benzer bir JSON yanıtı ile karşılaşırsınız:

```JSON

* Modelo de documentação automática com <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (já que o OpenAPI em si é baseado no JSON Schema).
* Projetado em cima desses padrões após um estudo meticuloso, em vez de uma reflexão breve.

      Request.Builder()
        .url("https://api.github.com/repos/square/okhttp/issues")
        .header("User-Agent", "OkHttp Headers.java")
        .addHeader("Accept", "application/json; q=0.5")
        .addHeader("Accept", "application/vnd.github.v3+json")
        .build()

    client.newCall(request).execute().use { response ->
      if (!response.isSuccessful) throw IOException("Unexpected code $response")

{!../../docs_src/body_nested_models/tutorial005.py!}
```

文字列は有効なURLであることが確認され、そのようにJSONスキーマ・OpenAPIで文書化されます。

## サブモデルのリストを持つ属性

Pydanticモデルを`list`や`set`などのサブタイプとして使用することもできます:

```Python hl_lines="20"
{!../../docs_src/body_nested_models/tutorial006.py!}
```

これは、次のようなJSONボディを期待します（変換、検証、ドキュメントなど）:

```JSON hl_lines="11"
{
    "name": "Foo",
    "description": "The pretender",

{!../../docs_src/request_forms_and_files/tutorial001.py!}
```

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。
