Оскільки `needy` є обов’язковим параметром, вам потрібно вказати його в URL:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

...це спрацює:

```JSON
{
    "item_id": "foo-item",
    "needy": "sooooneedy"
}
```

    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}
```

`needy` 是必选参数，因此要在 URL 中设置值：

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

...这样就正常了：

```JSON
{
    "item_id": "foo-item",
    "needy": "sooooneedy"
}
```

当然，把一些参数定义为必选，为另一些参数设置默认值，再把其它参数定义为可选，这些操作都是可以的：

{* ../../docs_src/query_params/tutorial006_py310.py hl[8] *}

本例中有 3 个查询参数：
