## Version 5.0.0-alpha.3

_2021-11-22_

 *  Fix: Change `Headers.toString()` to redact authorization and cookie headers.
 *  Fix: Don't do DNS to get the hostname for `RecordedRequest.requestUrl`. This was doing a DNS
    lookup for the local hostname, but we really just wanted the `Host` header.
 *  Fix: Don't crash with a `InaccessibleObjectException` when detecting the platform trust manager

이를 통해 **여러 위치**에서 **모델을 재사용** 할 수 있고 모든 매개변수에 대한 유효성 검사 및 메타데이터를 한 번에 선언할 수도 있습니다. 😍

/// note | 참고

이 기능은 FastAPI 버전 `0.115.0` 이후부터 지원됩니다. 🤓

///

/// tip | 팁

동일한 기술이 `Query`, `Cookie`, 그리고 `Header`에 적용됩니다. 😎

## Pydantic 모델을 사용한 쿠키

**Pydantic 모델**에 필요한 **쿠키** 매개변수를 선언한 다음, 해당 매개변수를 `Cookie`로 선언합니다:

Go 1.26 added a new `cryptocustomrand` setting that controls whether most crypto/...
APIs ignore the random `io.Reader` parameter. For Go 1.26, it defaults
