*Path operation*'ınızdan, bir JSON body'nin içine gömülü olsalar bile (ör. bir `dict`) *enum member*'ları döndürebilirsiniz.

İstemciye dönmeden önce, karşılık gelen değerlerine (bu durumda string) dönüştürülürler:

{* ../../docs_src/path_params/tutorial005_py310.py hl[18,21,23] *}

İstemcinizde şöyle bir JSON response alırsınız:

```JSON
{
  "model_name": "alexnet",

        db_person = Person.model_validate(person)
        return db_person

    client = TestClient(app)

    person_data = {"name": "Dive", "lastname": "Wilson"}
    response = client.post("/people/", json=person_data)
    data = response.json()
    assert response.status_code == 200, response.text
    assert data["name"] == person_data["name"]
    assert data["lastname"] == person_data["lastname"]

// Config storage class configuration
type Config struct {
	Standard    StorageClass `json:"standard"`
	RRS         StorageClass `json:"rrs"`
	Optimize    string       `json:"optimize"`
	inlineBlock int64

	initialized bool
}

// UnmarshalJSON - Validate SS and RRS parity when unmarshalling JSON.
func (sCfg *Config) UnmarshalJSON(data []byte) error {
	type Alias Config
	aux := &struct {
		*Alias

Но для сгенерированного клиента мы можем **модифицировать** ID операций OpenAPI непосредственно перед генерацией клиентов, чтобы сделать имена методов более приятными и **чистыми**.

Мы можем скачать OpenAPI JSON в файл `openapi.json`, а затем **убрать этот префикс‑тег** таким скриптом:

{* ../../docs_src/generate_clients/tutorial004_py310.py *}

//// tab | Node.js

```Javascript
{!> ../../docs_src/generate_clients/tutorial004.js!}

/// note | 備考

この場合、ボディから取得する`item`はオプションであることに注意してください。デフォルト値が`None`になっているためです。

///

## 複数のボディパラメータ { #multiple-body-parameters }

上述の例では、*path operations*は`Item`の属性を持つ以下のようなJSONボディを期待していました:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

しかし、`item`と`user`のように複数のボディパラメータを宣言することもできます:

* Documentação automática de modelos de dados com [**JSON Schema**](https://json-schema.org/) (já que o OpenAPI em si é baseado no JSON Schema).
* Projetado em torno desses padrões, após um estudo meticuloso. Em vez de uma camada improvisada por cima.

<span style="color: green;">[INFO]</span> Start watching changes
<span style="color: green;">[INFO]</span> Start detecting changes
```

And even more text

```json
{
    // This is a sample JSON code block
    "greeting": "Hello, world!" // Greeting
}
```

# Stream Data { #stream-data }

If you want to stream data that can be structured as JSON, you should [Stream JSON Lines](../tutorial/stream-json-lines.md).

But if you want to **stream pure binary data** or strings, here's how you can do it.

/// info

Added in FastAPI 0.134.0.

///

## Use Cases { #use-cases }

You could use this if you want to stream pure strings, for example directly from the output of an **AI LLM** service.
