@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

이제 다음 대신:

```json
{"message": "Hello World"}
```

이 응답은 이렇게 반환됩니다:

```json
{
  "message": "Hello World"
}
```

물론 JSON 포맷팅보다 더 유용하게 활용할 방법을 찾을 수 있을 것입니다. 😉

## 기본 응답 클래스

**FastAPI** 클래스 객체 또는 `APIRouter`를 생성할 때 기본적으로 사용할 응답 클래스를 지정할 수 있습니다.

Caching
=======

OkHttp implements an optional, off by default, Cache. OkHttp aims for RFC correct and
pragmatic caching behaviour, following common real-world browser like Firefox/Chrome and 
server behaviour when ambiguous.

# Basic Usage

```kotlin
  private val client: OkHttpClient = OkHttpClient.Builder()
      .cache(Cache(
          directory = File(application.cacheDir, "http_cache"),
          // $0.05 worth of phone storage in 2020

					IndexAny(x[:k], cs[:j])
				}
			})
		}
	}
}

func BenchmarkIndexAnyUTF8(b *testing.B) {
	x := Repeat([]byte{'#'}, 2048) // Never matches set
	cs := "你好世界, hello world. 你好世界, hello world. 你好世界, hello world."
	for k := 1; k <= 2048; k <<= 4 {
		for j := 1; j <= 64; j <<= 1 {
			b.Run(fmt.Sprintf("%d:%d", k, j), func(b *testing.B) {
				for i := 0; i < b.N; i++ {
					IndexAny(x[:k], cs[:j])

        String template = "Hello ${name}";
        Map<String, Object> paramMap = new HashMap<>();
        paramMap.put("name", "World");

        Object result = scriptEngine.evaluate(template, paramMap);
        assertEquals("Hello World", result);
    }

    // Test evaluate method with empty template
    public void test_evaluate_withEmptyTemplate() {
        String template = "";

./mc ready minio1 --insecure
./mc ready minio2 --insecure

# Prepare data for tests
echo -n "Preparing test data ..."
mkdir -p /tmp/data
echo "Hello world" >/tmp/data/plainfile

Now instead of returning:

```json
{"message": "Hello World"}
```

...this response will return:

```json
{
  "message": "Hello World"
}
```

Of course, you will probably find much better ways to take advantage of this than formatting JSON. 😉
