## Key Patterns

### Actions (Controllers)
- Located in `app.web.*` or `app.web.admin.*`
- Methods with `@Execute` are web endpoints
- DI via `@Resource` annotation
- `HtmlResponse` for JSP, `JsonResponse` for APIs

### Services
- Business logic in `app.service.*`
- Injected into Actions
- Use behavior classes to access OpenSearch

### Helpers

     */
    public HtmlResponse getRedirectResponseToLogin(final HtmlResponse response) {
        return response;
    }

    /**
     * Gets the redirect response to the root page.
     *
     * @param response The original response.
     * @return The redirect response.
     */
    public HtmlResponse getRedirectResponseToRoot(final HtmlResponse response) {
        return response;
    }

Также раньше, в предыдущих версиях, объект `request` передавался как часть пар ключ-значение в контексте для Jinja2.

///

/// tip | Совет

Если указать `response_class=HTMLResponse`, интерфейс документации сможет определить, что ответ будет в формате HTML.

///

/// note | Технические детали

Можно также использовать `from starlette.templating import Jinja2Templates`.

/// note | 笔记

在FastAPI 0.108.0，Starlette 0.29.0之前，`name`是第一个参数。
并且，在此之前，`request`对象是作为context的一部分以键值对的形式传递的。

///

/// tip | 提示

通过声明 `response_class=HTMLResponse`，API 文档就能识别响应的对象是 HTML。

///

/// note | 技术细节

您还可以使用 `from starlette.templating import Jinja2Templates`。

Also, before that, in previous versions, the `request` object was passed as part of the key-value pairs in the context for Jinja2.

///

/// tip

By declaring `response_class=HTMLResponse` the docs UI will be able to know that the response will be HTML.

///

/// note | Technical Details

You could also use `from starlette.templating import Jinja2Templates`.

Além disso, em versões anteriores, o objeto `request` era passado como parte dos pares chave-valor no "context" dict para o Jinja2.

///

/// tip | Dica

Ao declarar `response_class=HTMLResponse`, a documentação entenderá que a resposta será HTML.

///

/// note | Detalhes Técnicos

Você também poderia usar `from starlette.templating import Jinja2Templates`.

```

/// note | 참고

FastAPI 0.108.0 이전과 Starlette 0.29.0에서는 `name`이 첫 번째 매개변수였습니다.

또한 이전 버전에서는 `request` 객체가 Jinja2의 컨텍스트에서 키-값 쌍의 일부로 전달되었습니다.

///

/// tip | 팁

`response_class=HTMLResponse`를 선언하면 문서 UI 응답이 HTML임을 알 수 있습니다.

///

/// note | 기술 세부 사항
`from starlette.templating import Jinja2Templates`를 사용할 수도 있습니다.

import org.codelibs.fess.app.web.base.FessAdminAction;
import org.codelibs.fess.mylasta.action.FessUserBean;
import org.lastaflute.web.Execute;
import org.lastaflute.web.response.HtmlResponse;

/**
 * The action for admin pages.
 */
public class AdminAction extends FessAdminAction {

    /**
     * Default constructor.
     */
    public AdminAction() {
        super();
    }

Außerdem wurde in früheren Versionen das `request`-Objekt als Teil der Schlüssel-Wert-Paare im Kontext für Jinja2 übergeben.

///

/// tip | Tipp

Durch die Deklaration von `response_class=HTMLResponse` kann die Dokumentationsoberfläche erkennen, dass die <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr> HTML sein wird.

///

/// note | Technische Details

You will receive, as declared, a `list` of `bytes` or `UploadFile`s.

/// note | Technical Details

You could also use `from starlette.responses import HTMLResponse`.

**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.
