这里，我们使用 `SessionDep` 依赖项（一个 `Session` ）将新的 `Hero` 添加到 `Session` 实例中，提交更改到数据库，刷新 hero 中的数据，并返回它。

### 读取 Hero 类

我们可以使用 `select()` 从数据库中**读取** `Hero` 类，并利用 `limit` 和 `offset` 来对结果进行分页。

### 读取单个 Hero

我们可以**读取**单个 `Hero` 。

여기서 `SessionDep` 의존성 (즉, `Session`)을 사용하여 새로운 `Hero`를 `Session` 인스턴스에 추가하고, 데이터베이스에 변경 사항을 커밋하고, `hero` 데이터의 최신 상태를 갱신한 다음 이를 반환합니다.

### Heroes 조회하기

`select()`를 사용하여 데이터베이스에서 `Hero`를 **조회**할 수 있습니다. 결과에 페이지네이션을 적용하기 위해 `limit`와 `offset`을 포함할 수 있습니다.

[Moshi](https://github.com/square/moshi) is a handy API for converting between JSON and Java objects. Here we're using it to decode a JSON response from a GitHub API.

Note that `ResponseBody.charStream()` uses the `Content-Type` response header to select which charset to use when decoding the response body. It defaults to `UTF-8` if no charset is specified.
