	// To achieve this we create excess of goroutines most of which do local work.

Beachten Sie die automatische Vervollständigung für `name` und `price`, die in der FastAPI-Anwendung im `Item`-Modell definiert wurden.

Ainsi, la section :

va s'exécuter.

Cela ne se produira pas si vous importez ce module (fichier).

Par exemple, si vous avez un autre fichier `importer.py` qui contient :

```Python
from myapp import app

# Code supplémentaire
```

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

Wenn jedes JSON-Item, das Sie zurücksenden möchten, vom Typ `Item` ist (ein Pydantic-Modell) und es sich um eine async-Funktion handelt, können Sie den Rückgabetyp als `AsyncIterable[Item]` deklarieren:

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[1:24] hl[9:11,22] *}

实际上，HTTP `PUT` 也可以使用同样的技巧。

但这里用 `PATCH` 举例，因为它就是为这种用例设计的。

/// note | 注意

注意，输入模型仍会被验证。

因此，如果希望接收的部分更新可以省略所有属性，则需要一个所有属性都标记为可选（带默认值或 `None`）的模型。

为了区分用于**更新**（全部可选）和用于**创建**（必填）的模型，可以参考[更多模型](extra-models.md) 中介绍的思路。

La réponse ressemblerait à ceci :

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Récapitulatif { #recap }

Déclarez les en-têtes avec `Header`, en suivant le même modèle que pour `Query`, `Path` et `Cookie`.

Bunu çok basitleştiren birçok paket, veri modeli, veritabanı ve mevcut özelliklerle ilgili pek çok ödün vermek zorunda kalır. Hatta bazıları işi aşırı basitleştirirken arka planda güvenlik açıkları da barındırır.

**FastAPI**, hiçbir veritabanı, veri modeli veya araç konusunda ödün vermez.

Projenize en uygun olanları seçebilmeniz için size tam esneklik sağlar.
