### Top-level application { #top-level-application }

First, create the main, top-level, **FastAPI** application, and its *path operations*:

{* ../../docs_src/sub_applications/tutorial001.py hl[3, 6:8] *}

### Sub-application { #sub-application }

Then, create your sub-application, and its *path operations*.

This sub-application is just another standard FastAPI application, but this is the one that will be "mounted":

### 최상단 응용프로그램

먼저, 메인, 최상단의 **FastAPI** 응용프로그램과 이것의 *경로 동작*을 생성합니다:

{* ../../docs_src/sub_applications/tutorial001.py hl[3, 6:8] *}

### 하위 응용프로그램

다음으로, 하위 응용프로그램과 이것의 *경로 동작*을 생성합니다:

이 하위 응용프로그램은 또 다른 표준 FastAPI 응용프로그램입니다. 다만 이것은 “마운트”될 것입니다:

{* ../../docs_src/sub_applications/tutorial001.py hl[11, 14:16] *}

### 하위 응용프로그램 마운트

	google.golang.org/genproto/googleapis/rpc v0.0.0-20250422160041-2d3770c4ea7f // indirect
	google.golang.org/grpc v1.72.0 // indirect
	google.golang.org/protobuf v1.36.6 // indirect

        message[32] = 112; // Offset
        message[33] = 0;
        message[34] = 0;
        message[35] = 0;

        // User (8 bytes "user" in Unicode at offset 124)
        message[36] = 8; // Length
        message[37] = 0;
        message[38] = 8; // Max Length
        message[39] = 0;
        message[40] = 124; // Offset
        message[41] = 0;
        message[42] = 0;

So we put them in their own `dependencies` module (`app/dependencies.py`).

We will now use a simple dependency to read a custom `X-Token` header:

//// tab | Python 3.9+

```Python hl_lines="3  6-8" title="app/dependencies.py"
{!> ../../docs_src/bigger_applications/app_an_py39/dependencies.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="1  5-7" title="app/dependencies.py"

          .first() as X509TrustManager

      val sslContext =
        Platform.get().newSSLContext().apply {
          // TODO remove most of this code after https://github.com/bcgit/bc-java/issues/686
          init(null, arrayOf(trustManager), SecureRandom())
        }

      client =
        client
          .newBuilder()
          .sslSocketFactory(sslContext.socketFactory, trustManager)

Así que las ponemos en su propio módulo `dependencies` (`app/dependencies.py`).

Ahora utilizaremos una dependencia simple para leer un encabezado `X-Token` personalizado:

//// tab | Python 3.9+

```Python hl_lines="3  6-8" title="app/dependencies.py"
{!> ../../docs_src/bigger_applications/app_an_py39/dependencies.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="1  5-7" title="app/dependencies.py"
