gemounteten Unteranwendungen haben und alles würde korrekt funktionieren, da FastAPI sich um alle diese `root_path`s automatisch kümmert.

Mehr über den `root_path` und dessen explizite Verwendung erfahren Sie im Abschnitt [Hinter einem Proxy](behind-a-proxy.md){.internal-link target=_blank}....

                final String newId = ComponentUtil.getCrawlingInfoHelper().generateId(entity);
                final String oldId = (String) entity.get(fessConfig.getIndexFieldId());
                if (!newId.equals(oldId)) {
                    entity.put(fessConfig.getIndexFieldId(), newId);
                    entity.remove(fessConfig.getIndexFieldVersion());

быть свои собственные смонтированные подприложения, и всё будет работать корректно, потому что FastAPI автоматически обрабатывает все эти `root_path`.

Вы узнаете больше о `root_path` и о том, как использовать его явно, в разделе [За прокси](behind-a-proxy.md){.internal-link target=_blank}....

Using a relative URL is important to make sure your application keeps working even in an advanced use case like [Behind a Proxy](../../advanced/behind-a-proxy.md){.internal-link target=_blank}.

### 技术细节：`root_path`

以上述方式挂载子应用时，FastAPI 使用 ASGI 规范中的 `root_path` 机制处理挂载子应用路径之间的通信。

这样，子应用就可以为自动文档使用路径前缀。

并且子应用还可以再挂载子应用，一切都会正常运行，FastAPI 可以自动处理所有 `root_path`。

If you integrate your API with an OAuth2 provider, you will be able to authenticate and come back to the API docs with the acquired credentials. And interact with it using the real OAuth2 authentication.

Swagger UI will handle it behind the scenes for you, but it needs this "redirect" helper.
