## FastAPI で SSE をストリーミング { #stream-sse-with-fastapi }

FastAPI で SSE をストリーミングするには、*path operation 関数*で `yield` を使い、`response_class=EventSourceResponse` を設定します。

`EventSourceResponse` は `fastapi.sse` からインポートします:

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[1:25] hl[4,22] *}

yield された各アイテムは JSON にエンコードされ、SSE イベントの `data:` フィールドで送信されます。

    }

    @Test
    public void test_fields() {
        final Map<String, String[]> fields = Collections.singletonMap("title", new String[] { "test" });
        assertEquals("title:\"test\"", getQuery("", new String[0], fields, Collections.emptyMap(), false));

        final Map<String, String[]> multiFields = Collections.singletonMap("content", new String[] { "value1", "value2" });

Pour diffuser des SSE avec FastAPI, utilisez `yield` dans votre *fonction de chemin d'accès* et définissez `response_class=EventSourceResponse`.

Importez `EventSourceResponse` depuis `fastapi.sse` :

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[1:25] hl[4,22] *}

Chaque élément produit avec `yield` est encodé en JSON et envoyé dans le champ `data:` d’un événement SSE.
