ここで、クエリパラメータ `needy` は `str` 型の必須のクエリパラメータです

以下のURLをブラウザで開くと:

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

...必須のパラメータ `needy` を加えなかったので、以下の様なエラーが表示されます:

```JSON
{
    "detail": [
        {
            "loc": [
                "query",
                "needy"
            ],
            "msg": "field required",

        "needy"
      ],
      "msg": "Field required",
      "input": null,
      "url": "https://errors.pydantic.dev/2.1/v/missing"
    }
  ]
}
```

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"
}

```

Ici le paramètre `needy` est un paramètre requis (ou obligatoire) de type `str`.

Si vous ouvrez une URL comme :

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

...sans ajouter le paramètre requis `needy`, vous aurez une erreur :

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

```

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

Si abres tu navegador en una URL como:

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

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

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

```

Aqui o parâmetro de 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": [
        {
            "loc": [
                "query",
                "needy"
            ],

                "query",
                "needy"
            ],
            "msg": "field required",
            "type": "value_error.missing"
        }
    ]
}
```

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",

      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null,
      "url": "https://errors.pydantic.dev/2.1/v/missing"
    }
  ]
}
```

`needy` zorunlu bir parametre olduğundan dolayı bağlantıda tanımlanması gerekir:

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

...bu iş görür:

```JSON
{

      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null,
      "url": "https://errors.pydantic.dev/2.1/v/missing"
    }
  ]
}
```

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
{

```

📥 🔢 🔢 `needy` ✔ 🔢 🔢 🆎 `str`.

🚥 👆 📂 👆 🖥 📛 💖:

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

...🍵 ❎ ✔ 🔢 `needy`, 👆 🔜 👀 ❌ 💖:

```JSON
{
    "detail": [
        {
            "loc": [
                "query",
                "needy"
            ],
            "msg": "field required",

{!../../../docs_src/query_params/tutorial005.py!}
```

这里的查询参数 `needy` 是类型为 `str` 的必选查询参数。

在浏览器中打开如下 URL：

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

……因为路径中没有必选参数 `needy`，返回的响应中会显示如下错误信息：

```JSON
{
    "detail": [
        {
            "loc": [
                "query",
                "needy"
            ],
            "msg": "field required",
