to take advantage of sweet Kotlin features.

#### Credentials.basic()

The username and password parameters to `Credentials.basic()` are now non-null strings. In OkHttp
3.x, null would yield a username or password of "null".

#### HttpUrl.queryParameterValues()

The return type of `HttpUrl.queryParameterValues()` is `List<String?>`. Lists that may contain null

     | a unique name within the system (referred to by the 'id' attribute below).
     |
     | NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are
     |       used together.
     |
    <server>
      <id>deploymentRepo</id>
      <username>repouser</username>
      <password>repopwd</password>
    </server>

    <!-- Another sample, using keys to authenticate.

        final FessConfig fessConfig = ComponentUtil.getFessConfig();
        final String username = fessConfig.getFesenUsername();
        final String password = fessConfig.getFesenPassword();
        if (StringUtil.isNotBlank(username) && StringUtil.isNotBlank(password)) {
            final String value = username + ":" + password;

```Python
UserInDB(**user_dict)
```

다음과 같은 결과를 생성합니다:

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

혹은 더 정확히 말하자면, `user_dict`를 직접 사용하는 것은, 나중에 어떤 값이 추가되더라도 아래와 동일한 효과를 냅니다:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],

    @Required
    @Size(max = 100)
    public String username;

    /** The password for file authentication (maximum 100 characters). */
    @Size(max = 100)
    public String password;

    /**

     */
    @Required
    @Size(max = 100)
    public String username;

    /**

     */
    @Size(max = 100)
    public String password;

    public static OptionalEntity<WebConfig> getEntity(final CreateForm form, final String username, final long currentTime) {
        switch (form.crudMode) {
