Если вы установили ASGI‑сервер вручную, обычно нужно передать строку импорта в специальном формате, чтобы он смог импортировать ваше приложение FastAPI:

<div class="termy">

```console
$ uvicorn main:app --host 0.0.0.0 --port 80

<span style="color: green;">INFO</span>:     Uvicorn running on http://0.0.0.0:80 (Press CTRL+C to quit)
```

</div>

/// note | Примечание

Команда `uvicorn main:app` означает:

        // When
        NetbiosName unknownName = nameServiceClient.getUnknownName();

        // Then
        assertNotNull(unknownName, "Unknown name should not be null");
        assertEquals("0.0.0.0", unknownName.getName(), "Unknown name should be 0.0.0.0");
    }

    @Test
    @DisplayName("Should handle null hostname in getByName")
    void testGetByNameWithNull() {
        // When/Then

なので、以下:

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

は実行されます。

---

そのモジュール (ファイル) をインポートした場合は、こうはなりません。

したがって、次のようなもう一つのファイル `importer.py` がある場合:

```Python
from myapp import app

# Some more code
```

`myapp.py` 内の自動変数には、値が `"__main __"` の変数 `__name__` はありません。

したがって、以下の行:

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

は実行されません。

<div class="termy">

```console
$ uvicorn main:app --host 0.0.0.0 --port 80

<span style="color: green;">INFO</span>:     Uvicorn running on http://0.0.0.0:80 (Press CTRL+C to quit)
```

</div>

O comando `uvicorn main:app` refere-se a:
