- The default Bootstrap Token created with `kubeadm init` v1.8 expires
 and is deleted after 24 hours by default to limit the exposure of the
 valuable credential. You can create a new Bootstrap Token with
 `kubeadm token create` or make the default token permanently valid by specifying
 `--token-ttl 0` to `kubeadm init`. The default token can later be deleted with
 `kubeadm token delete`.

String unescaped = JsonUtil.unescape(escaped);

// Text tokenization
Tokenizer tokenizer = new Tokenizer("field1,field2,field3", ",");
while (tokenizer.hasMoreTokens()) {
    String token = tokenizer.nextToken();
    // Process each token
}

// Decimal formatting
DecimalFormat format = DecimalFormatUtil.getDecimalFormat("###,###.00");
```

### Exception Handling
```java
import org.codelibs.core.exception.*;

Если токен недействителен, то сразу же верните HTTP-ошибку.

{* ../../docs_src/security/tutorial004_an_py310.py hl[90:107] *}

## Обновление *операции пути* `/token` { #update-the-token-path-operation }

Создайте `timedelta` со временем истечения срока действия токена.

Создайте реальный токен доступа JWT и верните его

OAuth2의 경우 문자열일 뿐입니다.

///

## `username`과 `password`를 가져오는 코드

이제 **FastAPI**에서 제공하는 유틸리티를 사용하여 이를 처리해 보겠습니다.

### `OAuth2PasswordRequestForm`

먼저 `OAuth2PasswordRequestForm`을 가져와 `/token`에 대한 *경로 작동*에서 `Depends`의 의존성으로 사용합니다.

{* ../../docs_src/security/tutorial003.py hl[4,76] *}

`OAuth2PasswordRequestForm`은 다음을 사용하여 폼 본문을 선언하는 클래스 의존성입니다:

* `username`.
* `password`.
