]
}
```

`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

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"
            ],

          # To be able to commit it needs to fetch the head of the branch, not the
          # merge commit
          ref: ${{ github.head_ref }}
          # And it needs the full history to be able to compute diffs
          fetch-depth: 0
          # A token other than the default GITHUB_TOKEN is needed to be able to trigger CI
          token: ${{ secrets.PRE_COMMIT }}
      # pre-commit lite ci needs the default checkout configs to work

Тут `needy` – обов’язковий query параметр типу `str`.

Якщо Ви відкриєте у браузері URL-адресу:

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

...без додавання обов’язкового параметра `needy`, Ви побачите помилку:

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

from fastapi import FastAPI

app = FastAPI()


@app.get("/items/{item_id}")
async def read_user_item(
    item_id: str, needy: str, skip: int = 0, limit: int | None = None
):
    item = {"item_id": item_id, "needy": needy, "skip": skip, "limit": limit}

        "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"
}
```

          COMMAND: ${{ github.event.inputs.command }}

  translate:
    if: github.repository_owner == 'fastapi'
    needs: langs
    runs-on: ubuntu-latest
    strategy:
      matrix:
        lang: ${{ fromJson(needs.langs.outputs.langs) }}
        command: ${{ fromJson(needs.langs.outputs.commands) }}
    permissions:

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",

{* ../../docs_src/query_params/tutorial005.py hl[6:7] *}

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",

        scope.enter();

        Object o1 = new Object();
        scope.seed(Object.class, o1);
        assertSame(o1, scope.scope(Key.get(Object.class), () -> null).get());

        scope.enter();
        Object o2 = new Object();
        scope.seed(Object.class, o2);
        assertSame(o2, scope.scope(Key.get(Object.class), () -> null).get());

        scope.exit();
