## FastAPI で JSON Lines をストリームする { #stream-json-lines-with-fastapi }

FastAPI で JSON Lines をストリームするには、*path operation 関数*で `return` を使う代わりに、`yield` を使って各アイテムを順に生成します。

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[1:24] hl[24] *}

送り返す各 JSON アイテムが `Item`（Pydantic モデル）型で、関数が async の場合、戻り値の型を `AsyncIterable[Item]` と宣言できます:

Bir async generator veya normal generator/iterator (içinde `yield` olan bir fonksiyon) alır ve response body’yi stream eder.

{* ../../docs_src/custom_response/tutorial007_py310.py hl[3,16] *}

/// note | Teknik Detaylar

* Sonra o **response** üzerinde bir işlem yapabilir veya gerekli herhangi bir kodu çalıştırabilir.
* Son olarak **response**'u döndürür.

/// note | Teknik Detaylar

`yield` ile dependency'leriniz varsa, çıkış (exit) kodu middleware'den *sonra* çalışır.

class StaticJAASConfigurationTest {

    // Constants used in assertions
    private static final String EXPECTED_LOGIN_MODULE = "com.sun.security.auth.module.Krb5LoginModule";

    @Test
    @DisplayName("Default constructor yields REQUIRED Krb5 entry with empty options")
    void defaultConstructor_producesRequiredKrb5EntryWithEmptyOptions() {
        // Arrange
        StaticJAASConfiguration cfg = new StaticJAASConfiguration();

        // Act

* Il peut faire quelque chose avec cette **réponse** ou exécuter tout code nécessaire.
* Enfin, il renvoie la **réponse**.

/// note | Détails techniques

Si vous avez des dépendances avec `yield`, le code de sortie s’exécutera après le middleware.

* Sie kann etwas mit dieser **Response** tun oder beliebigen Code ausführen.
* Dann gibt sie die **Response** zurück.

/// note | Technische Details

Wenn Sie Abhängigkeiten mit `yield` haben, wird der Exit-Code *nach* der Middleware ausgeführt.

Wenn es Hintergrundtasks gab (dies wird später im [Hintergrundtasks](background-tasks.md)-Abschnitt behandelt), werden sie *nach* allen Middlewares ausgeführt.

///

* Ele pode fazer algo com essa **resposta** ou executar qualquer código necessário.
* Então ele retorna a **resposta**.

/// note | Detalhes Técnicos

Se você tiver dependências com `yield`, o código de saída será executado *depois* do middleware.

Nimmt einen asynchronen Generator oder einen normalen Generator/Iterator (eine Funktion mit `yield`) und streamt den Responsebody.
