### Post Streaming ([.kt][PostStreamingKotlin], [.java][PostStreamingJava])

Here we `POST` a request body as a stream. The content of this request body is being generated as it's being written. This example streams directly into the [Okio](https://github.com/square/okio) buffered sink. Your programs may prefer an `OutputStream`, which you can get from `BufferedSink.outputStream()`.

            InputLocationTracker tracker,
            ModelBuildingRequest request) {
        if (string == null) {
            // NOTE: The check for missing plugin versions is handled directly by the model builder
            return true;
        }

        Severity errOn30 = getSeverity(request, ModelBuildingRequest.VALIDATION_LEVEL_MAVEN_3_0);

Por padrão, o **FastAPI** retornará respostas JSON.

Você pode sobrescrever isso retornando uma `Response` diretamente, como visto em [Retornando uma Resposta Diretamente](response-directly.md).

# カスタムレスポンス - HTML、ストリーム、ファイル、その他 { #custom-response-html-stream-file-others }

デフォルトでは、**FastAPI** はJSONレスポンスを返します。

[レスポンスを直接返す](response-directly.md)で見たように、`Response` を直接返してこの挙動を上書きできます。

しかし、`Response`（または `JSONResponse` のような任意のサブクラス）を直接返す場合、（`response_model` を宣言していても）データは自動的に変換されず、ドキュメントも自動生成されません（例えば、生成されるOpenAPIの一部としてHTTPヘッダー `Content-Type` に特定の「メディアタイプ」を含めるなど）。
