## Get the user { #get-the-user }

`get_current_user` will use a (fake) utility function we created, that takes a token as a `str` and returns our Pydantic `User` model:

fazendo antes diretamente na *operação de rota*, a nossa nova dependência `get_current_user` receberá um `token` como uma `str` da subdependência `oauth2_scheme`:

## 특별한 타입과 검증

`str`, `int`, `float` 등과 같은 단일 타입과는 별개로, `str`을 상속하는 더 복잡한 단일 타입을 사용할 수 있습니다.

모든 옵션을 보려면, <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">Pydantic's exotic types</a> 문서를 확인하세요. 다음 장에서 몇가지 예제를 볼 수 있습니다.

예를 들어 `Image` 모델 안에 `url` 필드를 `str` 대신 Pydantic의 `HttpUrl`로 선언할 수 있습니다:

	fmt.Printf("%s\n", bytes.ToTitle([]byte("брат")))
	// Output:
	// LOUD NOISES
	// БРАТ
}

func ExampleToTitleSpecial() {
	str := []byte("ahoj vývojári golang")
	totitle := bytes.ToTitleSpecial(unicode.AzeriCase, str)
	fmt.Println("Original : " + string(str))
	fmt.Println("ToTitle : " + string(totitle))
	// Output:
	// Original : ahoj vývojári golang
	// ToTitle : AHOJ VÝVOJÁRİ GOLANG
}

        circuitBreaker.call(() -> "success");

        SimpleCircuitBreaker.Statistics stats = circuitBreaker.getStatistics();
        String str = stats.toString();

        assertNotNull(str);
        assertTrue(str.contains("test"));
        assertTrue(str.contains("CLOSED"));
        assertTrue(str.contains("100.00%"));
    }
