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"
            ],

  }

  private static void assertHash(int seed, long expected1, long expected2, String stringInput) {

    assertEquals(expected, murmur3_128(seed).hashBytes(input));
    assertEquals(expected, murmur3_128(seed).newHasher().putBytes(input).hash());
  }

여기 쿼리 매개변수 `needy`는 `str`형인 필수 쿼리 매개변수입니다.

브라우저에서 아래와 같은 URL을 연다면:

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

...필수 매개변수 `needy`를 넣지 않았기 때문에 아래와 같은 오류를 보게 됩니다:

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

  unit-test:
    name: "${{ matrix.bucket.name }} (Unit Test)"
    permissions:
      contents: read

    needs: build
    strategy:
      matrix:
        bucket: ${{ fromJson(needs.build.outputs.matrix) }}
      fail-fast: false
    steps:
      - name: git clone
        uses: actions/checkout@v5
      - name: setup java

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"
            ],

      "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"
}
```
