```json

/// tip | 팁

`aGVsbG8=`는 `hello`의 base64 인코딩입니다.

///

그러면 Pydantic이 base64 문자열을 디코딩하여 모델의 `data` 필드에 원래 바이트를 제공합니다.

다음과 같은 응답을 받게 됩니다:

```json
{
  "description": "Some data",
  "content": "hello"
}
```

## 출력 데이터용 Pydantic `bytes` { #pydantic-bytes-for-output-data }

    public void test_toLowercaseWildcard_enabled() {
        queryCommand.setLowercaseWildcard(true);

        assertEquals("test", queryCommand.toLowercaseWildcard("TEST"));
        assertEquals("hello", queryCommand.toLowercaseWildcard("Hello"));
        assertEquals("mixed123", queryCommand.toLowercaseWildcard("MiXeD123"));
        assertEquals("already_lower", queryCommand.toLowercaseWildcard("already_lower"));
    }

    @Test

    "data": "aGVsbG8="
}
```

/// tip | Tipp

`aGVsbG8=` ist die base64-Kodierung von `hello`.

///

Anschließend dekodiert Pydantic den base64-String und stellt Ihnen die ursprünglichen Bytes im Feld `data` des Modells bereit.

Sie erhalten eine Response wie:

```json
{
  "description": "Some data",
  "content": "hello"
}
```
