public IntegerSubscriber(String name) {
      this.name = name;
    }

    @Subscribe
    public void handleInteger(Integer integer) {
      dispatchedSubscribers.add(this);
      dispatcher.dispatch("hello", stringSubscribers.iterator());
    }

    @Override
    public String toString() {
      return name;
    }
  }

  public final class StringSubscriber {
    private final String name;

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.

Erstellen Sie eine Datei `main.py` mit:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


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


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

<details markdown="1">

{* ../../docs_src/custom_response/tutorial009c_py39.py hl[9:14,17] *}

Теперь вместо того, чтобы возвращать:

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

...этот ответ вернёт:

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

Разумеется, вы наверняка найдёте гораздо более полезные способы воспользоваться этим, чем просто форматирование JSON. 😉

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


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


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

<details markdown="1">

		t.Fatalf("Failed to create 'uuid-ossp' extension, but got error %v", err)
	}

	DB.Migrator().DropTable(&Post{}, &Category{}, "post_categories")
	DB.AutoMigrate(&Post{}, &Category{})

	post := Post{
		Title: "Hello World",
		Categories: []*Category{
			{Title: "Coding"},
			{Title: "Golang"},
		},
	}

	if err := DB.Create(&post).Error; err != nil {
		t.Errorf("Failed, got error: %v", err)
	}
}

{* ../../docs_src/custom_response/tutorial009c_py39.py hl[9:14,17] *}

Ahora en lugar de devolver:

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

...este response devolverá:

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

Por supuesto, probablemente encontrarás formas mucho mejores de aprovechar esto que formatear JSON. 😉

		t.Fatalf("Failed to create 'uuid-ossp' extension, but got error %v", err)
	}

	DB.Migrator().DropTable(&Post{}, &Category{}, "post_categories")
	DB.AutoMigrate(&Post{}, &Category{})

	post := Post{
		Title: "Hello World",
		Categories: []*Category{
			{Title: "Coding"},
			{Title: "Golang"},
		},
	}

	if err := DB.Create(&post).Error; err != nil {
		t.Errorf("Failed, got error: %v", err)
	}
}

			[]byte("foo"),
		}, {
			&Header{Name: "world", Mode: 0640, Size: int64(5)},
			[]byte("hello"),
		}},
	}, {
		"GNU",
		[]file{{
			&Header{Name: "bar", Mode: 0640, Size: int64(3), Devmajor: -1},
			[]byte("foo"),
		}, {
			&Header{Name: "world", Mode: 0640, Size: int64(5), Devmajor: -1},
			[]byte("hello"),
		}},
	}, {
		"PAX",
		[]file{{

Создайте файл `main.py` со следующим содержимым:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


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


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```
