Das bedeutet, dass anstelle des normalen Prozesses, bei dem Ihre Benutzer Requests an Ihre API senden, **Ihre API** (oder Ihre App) **Requests an deren System** (an deren API, deren App) senden könnte.

Das wird normalerweise als **Web<abbr title="Haken, Einhängepunkt">hook</abbr>** bezeichnet.

Kısmi güncellemeler almak istiyorsanız, Pydantic modelinin `.model_dump()` metodundaki `exclude_unset` parametresini kullanmak çok faydalıdır.

Örneğin: `item.model_dump(exclude_unset=True)`.

Bu, `item` modeli oluşturulurken set edilmiş verileri içeren; varsayılan değerleri hariç tutan bir `dict` üretir.

    return {"item_id": item_id, "q": q}


@app.put("/items/{item_id}")
def update_item(item_id: int, item: Item):
    return {"item_name": item.name, "item_id": item_id}
```

在介绍依赖项与安全的章节中，你可以更直观地看到用 `raise` 异常代替 `return` 值的优势。

本例中，客户端用不存在的 `ID` 请求 `item` 时，触发状态码为 `404` 的异常：

{* ../../docs_src/handling_errors/tutorial001_py310.py hl[11] *}

### 响应结果 { #the-resulting-response }

请求为 `http://example.com/items/foo`（`item_id` 为 `"foo"`）时，客户端会接收到 HTTP 状态码 200 及如下 JSON 响应结果：

```JSON
{
  "item": "The Foo Wrestlers"
}
```
