* Und viele andere Dinge

## Fazit { #conclusion }

Wenn Sie das alles gelesen und verstanden haben, wissen Sie jetzt **viel mehr** über virtuelle Umgebungen als viele Entwickler da draußen. 🤓

/// warning | Achtung

Sie benötigen diese technischen Details höchstwahrscheinlich nicht.

**FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette.

/// warning

Have in mind that the `RequestValidationError` contains the information of the file name and line where the validation error happens so that you can show it in your logs with the relevant information if you want to.

UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
    hashed_password = hashed_password,
)
```

/// warning | 경고

추가적으로 제공된 함수 `fake_password_hasher`와 `fake_save_user`는 데이터 흐름을 시연하기 위한 예제일 뿐이며, 실제 보안을 제공하지 않습니다.

## 중복 줄이기

코드 중복을 줄이는 것은 **FastAPI**의 핵심 아이디어 중 하나입니다.

 * but given that any public suffix may become a host without warning, it is better to err on the
 * side of permissiveness and thus avoid spurious rejection of valid sites. Of course, to actually
 * determine addressability of any host, clients of this class will need to perform their own DNS

   * lookup would fail with an IllegalAccessException. That may then trigger use of Unsafe (possibly
   * with a warning under recent JVMs), or it may fall back even further to
   * AtomicReferenceFieldUpdaterAtomicHelper, which would fail with a similar problem to
   * VarHandleAtomicHelperMaker, forcing us all the way to SynchronizedHelper.
