However, they are now deprecated as you will now get better performance by using a [Response Model - Return Type](https://fastapi.tiangolo.com/tutorial/response-model/).

That way, Pydantic will serialize the data into JSON bytes on the Rust side, which will achieve better performance than these custom JSON responses.

public interface IndexExportFormatter {

    /**
     * Returns the file extension for this format (e.g. ".html", ".json").
     *
     * @return the file extension including the leading dot
     */
    String getFileExtension();

    /**
     * Returns the default index file name for this format (e.g. "index.html", "index.json").
     *
     * @return the index file name
     */
    String getIndexFileName();

    /**

/// warning | Uyarı

Bir *path operation* içinde birden fazla `File` ve `Form` parametresi tanımlayabilirsiniz; ancak request'in body'si `application/json` yerine `multipart/form-data` ile encode edileceği için, JSON olarak almayı beklediğiniz `Body` alanlarını aynı anda tanımlayamazsınız.

Bu **FastAPI** kısıtı değildir; HTTP protokolünün bir parçasıdır.

从 `fastapi.sse` 导入 `ServerSentEvent`：

{* ../../docs_src/server_sent_events/tutorial002_py310.py hl[4,26] *}

`data` 字段始终会被编码为 JSON。你可以传入任何可被序列化为 JSON 的值，包括 Pydantic 模型。

## 原始数据 { #raw-data }

如果你需要发送**不**进行 JSON 编码的数据，请使用 `raw_data` 而不是 `data`。

这对于发送预格式化文本、日志行或特殊的 <dfn title="用于指示特殊条件或状态的值">"哨兵"</dfn> 值（例如 `[DONE]`）很有用。

{* ../../docs_src/server_sent_events/tutorial003_py310.py hl[17] *}

Например:

* Передаёте *path*-параметры или *query*-параметры, вписав их непосредственно в строку URL.
* Передаёте JSON в теле запроса, передав Python-объект (например: `dict`) через именованный параметр `json`.
* Если же Вам необходимо отправить *форму с данными* вместо JSON, то используйте параметр `data` вместо `json`.
* Для передачи *HTTP-заголовков*, передайте объект `dict` через параметр `headers`.

* Automatische Dokumentation der Datenmodelle mit [**JSON Schema**](https://json-schema.org/) (da OpenAPI selbst auf JSON Schema basiert).
* Um diese Standards herum entworfen, nach sorgfältigem Studium. Statt einer nachträglichen Schicht darüber.

avec un corps JSON :

```JSON
{
    "id": "2expen51ve",
    "customer": "Mr. Richie Rich",
    "total": "9999"
}
```

alors *votre API* traitera la facture et, à un moment ultérieur, enverra une requête de callback à `callback_url` (l’*API externe*) :

```
https://www.external.org/events/invoices/2expen51ve
```

avec un corps JSON contenant quelque chose comme :

```

使用如下 JSON 请求体：

```JSON
{
    "id": "2expen51ve",
    "customer": "Mr. Richie Rich",
    "total": "9999"
}
```

然后，您的 API 就会处理发票，并在某个点之后，发送回调请求至 `callback_url`（外部 API）：

```
https://www.external.org/events/invoices/2expen51ve
```

JSON 请求体包含如下内容：

```JSON
{
    "description": "Payment celebration",
    "paid": true

                            Property<String> getSourceCompatibility();
                        }
                    """
                )
                withJsonFile(
                    "resources/upgraded-properties.json",
                    """
                        [{
                            "containingType": "com.example.Task",
                            "methodName": "getSourceCompatibility",
