### Hauptanwendung

Erstellen Sie zunächst die Hauptanwendung **FastAPI** und deren *Pfadoperationen*:

```Python hl_lines="3  6-8"
{!../../../docs_src/sub_applications/tutorial001.py!}
```

### Unteranwendung

Erstellen Sie dann Ihre Unteranwendung und deren *Pfadoperationen*.

## 🗜 **FastAPI** 🈸

"🗜" ⛓ ❎ 🍕 "🔬" 🈸 🎯 ➡, 👈 ⤴️ ✊ 💅 🚚 🌐 🔽 👈 ➡, ⏮️ _➡ 🛠️_ 📣 👈 🎧-🈸.

### 🔝-🎚 🈸

🥇, ✍ 👑, 🔝-🎚, **FastAPI** 🈸, & 🚮 *➡ 🛠️*:

```Python hl_lines="3  6-8"

如果需要两个独立的 FastAPI 应用，拥有各自独立的 OpenAPI 与文档，则需设置一个主应用，并**挂载**一个（或多个）子应用。

## 挂载 **FastAPI** 应用

**挂载**是指在特定路径中添加完全**独立**的应用，然后在该路径下使用*路径操作*声明的子应用处理所有事务。

### 顶层应用

首先，创建主（顶层）**FastAPI** 应用及其*路径操作*：

```Python hl_lines="3  6-8"
{!../../../docs_src/sub_applications/tutorial001.py!}
```

### 子应用

接下来，创建子应用及其*路径操作*。

子应用只是另一个标准 FastAPI 应用，但这个应用是被**挂载**的应用：

```Python hl_lines="11  14-16"

    ),

    RESOURCES(MODULES, "resources", introducedIn("1.9-rc-1")),

    TRANSFORMS(null, "transforms", introducedIn("3.5-rc-1")
        .changedTo(2, "5.1")
        .changedTo(3, "6.8-rc-1")
        // Introduced move semantics
        .changedTo(4, "8.6-rc-1")
        .retiredIn("8.8-rc-1")
    );

    private final String name;
    private final CacheVersionMapping versionMapping;

### Top-level application

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

```Python hl_lines="3  6-8"
{!../../../docs_src/sub_applications/tutorial001.py!}
```

### Sub-application

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