/// info | 情報

パラメータ `response_class` は、レスポンスの「メディアタイプ」を定義するためにも使用されます。

この場合、HTTPヘッダー `Content-Type` には `text/html` が設定されます。

そして、OpenAPIにもそのようにドキュメント化されます。

///

### `Response` を返す { #return-a-response }

[レスポンスを直接返す](response-directly.md)で見たように、*path operation* の中でレスポンスを直接返して上書きすることもできます。

# Server-Sent Events (SSE) { #server-sent-events-sse }

Sie können Daten mithilfe von **Server-Sent Events** (SSE) an den Client streamen.

Das ist ähnlich wie [JSON Lines streamen](stream-json-lines.md), verwendet aber das Format `text/event-stream`, das von Browsern nativ mit der [die `EventSource`-API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource) unterstützt wird.
