위 예시에서는 3가지 쿼리 매개변수가 있습니다:

* `needy`, 필수적인 `str`.
* `skip`, 기본값이 `0`인 `int`.
* `limit`, 선택적인 `int`.

/// tip | "팁"

[경로 매개변수](path-params.md#_8){.internal-link target=_blank}와 마찬가지로 `Enum`을 사용할 수 있습니다.

### 非同期コードの他の形式

`async` と `await` を使用するスタイルは、この言語では比較的新しいものです。

非同期コードの操作がはるかに簡単になります。

等価な (またはほとんど同一の) 構文が、最近のバージョンのJavaScript (ブラウザおよびNodeJS) にも最近組み込まれました。

しかし、その前は、非同期コードの処理はかなり複雑で難解でした。

## Install custom exception handlers

You can add custom exception handlers with <a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">the same exception utilities from Starlette</a>.

Let's say you have a custom exception `UnicornException` that you (or a library you use) might `raise`.

    /**
     * Instantiate a random access file from a {@link SmbFile}
     * 
     * @param file
     * @param mode
     * @throws SmbException

    public SmbRandomAccessFile ( SmbFile file, String mode ) throws SmbException {
        this(file, mode, SmbConstants.DEFAULT_SHARING, false);
    }
