"query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

As `needy` is a required parameter, you would need to set it in the URL:

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

...this would work:

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

from fastapi import FastAPI

app = FastAPI()


@app.get("/items/{item_id}")
async def read_user_item(item_id: str, needy: str):
    item = {"item_id": item_id, "needy": needy}

      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

`needy` zorunlu bir parametre olduğundan, URL'de ayarlamanız gerekir:

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

...bu çalışır:

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

      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

Da `needy` ein erforderlicher Parameter ist, müssen Sie ihn in der URL setzen:

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

... Das funktioniert:

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

  ]
}
```

`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：

* `needy`，必选的 `str` 类型参数
* `skip`，默认值为 `0` 的 `int` 类型参数

        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

Comme `needy` est un paramètre requis, vous devez le définir dans l'URL :

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

... cela fonctionnerait :

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

        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

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"
}
```

        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

Поскольку `needy` является обязательным параметром, вам необходимо указать его в URL-адресе:

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

...это будет работать:

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

Aquí el parámetro de query `needy` es un parámetro de query requerido de tipo `str`.

Si abres en tu navegador una URL como:

```
http://127.0.0.1:8000/items/foo-item
```

...sin agregar el parámetro requerido `needy`, verás un error como:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],

Aqui o parâmetro da consulta `needy` é um valor obrigatório, do tipo `str`.

Se você abrir no seu navegador a URL:

```
http://127.0.0.1:8000/items/foo-item
```

... sem adicionar o parâmetro obrigatório `needy`, você verá um erro como:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
