### コールバック用 APIRouter を作成 { #create-a-callback-apirouter }

まず、1 つ以上のコールバックを含む新しい `APIRouter` を作成します。

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[1,23] *}

### コールバックの path operation を作成 { #create-the-callback-path-operation }

上で作成したのと同じ `APIRouter` を使って、コールバックの *path operation* を作成します。

見た目は通常の FastAPI の *path operation* と同じです:

	var buf bytes.Buffer
	for i := 0; i < 4; i++ {
		b := buf.AvailableBuffer()
		b = strconv.AppendInt(b, int64(i), 10)
		b = append(b, ' ')
		buf.Write(b)
	}
	os.Stdout.Write(buf.Bytes())
	// Output: 0 1 2 3
}

func ExampleBuffer_Cap() {
	buf1 := bytes.NewBuffer(make([]byte, 10))
	buf2 := bytes.NewBuffer(make([]byte, 0, 10))
	fmt.Println(buf1.Cap())
	fmt.Println(buf2.Cap())
	// Output:
	// 10
	// 10
}
