### 😐 **FastAPI**

🥇, ✍ 🌐 👆 **FastAPI** 🈸 🛎:

```Python hl_lines="1  4  7-9"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### 🏗 🗄 🔗

⤴️, ⚙️ 🎏 🚙 🔢 🏗 🗄 🔗, 🔘 `custom_openapi()` 🔢:

```Python hl_lines="2  15-20"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### 🔀 🗄 🔗

🔜 👆 💪 🚮 📄 ↔, ❎ 🛃 `x-logo` `info` "🎚" 🗄 🔗:

```Python hl_lines="21-23"

### Normal **FastAPI**

First, write all your **FastAPI** application as normally:

```Python hl_lines="1  4  7-9"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### Generate the OpenAPI schema

Then, use the same utility function to generate the OpenAPI schema, inside a `custom_openapi()` function:

```Python hl_lines="2  15-21"

```Python hl_lines="1  4  7-9"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### Das OpenAPI-Schema generieren

Verwenden Sie dann dieselbe Hilfsfunktion, um das OpenAPI-Schema innerhalb einer `custom_openapi()`-Funktion zu generieren:

```Python hl_lines="2  15-21"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### Das OpenAPI-Schema ändern

### 常规 **FastAPI**

首先，编写常规 **FastAPI** 应用：

```Python hl_lines="1  4  7-9"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### 生成 OpenAPI 概图

然后，在 `custom_openapi()` 函数里使用 `get_openapi()` 工具函数生成 OpenAPI 概图：

```Python hl_lines="2  15-20"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### 修改 OpenAPI 概图
