Oder Sie haben andere Möglichkeiten, mit dem WebSocket-Endpunkt zu kommunizieren.

Für dieses Beispiel verwenden wir jedoch ein sehr einfaches HTML-Dokument mit etwas JavaScript, alles in einem langen String.

Das ist natürlich nicht optimal und man würde das nicht in der Produktion machen.

In der Produktion hätten Sie eine der oben genannten Optionen.

* O **modelo de entrada** precisa ser capaz de ter uma senha.
* O **modelo de saída** não deve ter uma senha.
* O **modelo de banco de dados** provavelmente precisaria ter uma senha criptografada.

    Nunca armazene senhas em texto simples dos usuários. Sempre armazene uma "hash segura" que você pode verificar depois.

Das kann insbesondere eine gute Alternative zur Logik in einer Middleware sein.

Wenn Sie beispielsweise den Requestbody lesen oder manipulieren möchten, bevor er von Ihrer Anwendung verarbeitet wird.

!!! danger "Gefahr"
    Dies ist eine „fortgeschrittene“ Funktion.

    Wenn Sie gerade erst mit **FastAPI** beginnen, möchten Sie diesen Abschnitt vielleicht überspringen.

## Anwendungsfälle

Einige Anwendungsfälle sind:

* The **input model** needs to be able to have a password.
* The **output model** should not have a password.
* The **database model** would probably need to have a hashed password.

!!! danger
    Never store user's plaintext passwords. Always store a "secure hash" that you can then verify.

In particular, this may be a good alternative to logic in a middleware.

For example, if you want to read or manipulate the request body before it is processed by your application.

!!! danger
    This is an "advanced" feature.

    If you are just starting with **FastAPI** you might want to skip this section.

## Use cases

이제 브라우저가 비밀번호로 사용자를 만들 때마다 API는 응답으로 동일한 비밀번호를 반환합니다.

이 경우, 사용자가 스스로 비밀번호를 발신했기 때문에 문제가 되지 않을 수 있습니다.

그러나 동일한 모델을 다른 *경로 작동*에서 사용할 경우, 모든 클라이언트에게 사용자의 비밀번호를 발신할 수 있습니다.

!!! danger "위험"
    절대로 사용자의 평문 비밀번호를 저장하거나 응답으로 발신하지 마십시오.

## 출력 모델 추가

대신 평문 비밀번호로 입력 모델을 만들고 해당 비밀번호 없이 출력 모델을 만들 수 있습니다:

```Python hl_lines="9  11  16"
{!../../../docs_src/response_model/tutorial003.py!}
```

Default port '8021' can be changed via

```
--ftp="address=:3021"
```

### Change FTP passive port range

By default FTP requests OS to give a free port automatically, however you may want to restrict
this to specific ports in certain restricted environments via

```
--ftp="passive-port-range=30000-40000"
```

### Change default SFTP port

Default port '8022' can be changed via

```
