### **FastAPI** app file { #fastapi-app-file }

Let's say you have a file structure as described in [Bigger Applications](bigger-applications.md){.internal-link target=_blank}:

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

In the file `main.py` you have your **FastAPI** app:


{* ../../docs_src/app_testing/main.py *}

import org.codelibs.fess.Constants;
import org.codelibs.fess.app.pager.DataConfigPager;
import org.codelibs.fess.app.service.DataConfigService;
import org.codelibs.fess.app.web.CrudMode;
import org.codelibs.fess.app.web.api.ApiResult;
import org.codelibs.fess.app.web.api.ApiResult.ApiConfigResponse;
import org.codelibs.fess.app.web.api.ApiResult.ApiResponse;
import org.codelibs.fess.app.web.api.ApiResult.ApiUpdateResponse;

```

1. Kopiere die Datei `main.py` direkt in das Verzeichnis `/code` (ohne ein Verzeichnis `./app`).

2. Führe Uvicorn aus und weisen es an, das `app`-Objekt von `main` zu importieren (anstatt von `app.main` zu importieren).

Passen Sie dann den Uvicorn-Befehl an, um das neue Modul `main` anstelle von `app.main` zu verwenden, um das FastAPI-Objekt `app` zu importieren.

## Deployment-Konzepte

Então, a seção:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

vai executar.

---

Isso não acontecerá se você importar esse módulo (arquivo).

Então, se você tiver outro arquivo `importer.py` com:

```Python
from myapp import app

# Mais um pouco de código
```

import org.codelibs.fess.app.service.FileConfigService;
import org.codelibs.fess.app.web.CrudMode;
import org.codelibs.fess.app.web.api.ApiResult;
import org.codelibs.fess.app.web.api.ApiResult.ApiConfigResponse;
import org.codelibs.fess.app.web.api.ApiResult.ApiResponse;
import org.codelibs.fess.app.web.api.ApiResult.ApiUpdateResponse;

```

1. Скопируйте непосредственно файл `main.py` в директорию `/code` (не указывайте `./app`).

2. При запуске Uvicorn укажите ему, что объект `app` нужно импортировать из файла `main` (вместо импортирования из `app.main`).

Настройте Uvicorn на использование `main` вместо `app.main` для импорта объекта `app`.

Note that the go_darwin_$GOARCH_exec wrapper uninstalls any existing app identified by
the bundle id before installing a new app. If the uninstalled app is the last app by
the developer identity, the device might also remove the permission to run apps from
that developer, and the exec wrapper will fail to install the new app. To avoid that,
install another app with the same developer identity but with a different bundle id.
