OpenAPI 概图会自动添加标签，供 API 文档接口使用：

<img src="/img/tutorial/path-operation-configuration/image01.png">

## `summary` 和 `description` 参数

路径装饰器还支持 `summary` 和 `description` 这两个参数：

```Python hl_lines="20-21"
{!../../../docs_src/path_operation_configuration/tutorial003.py!}

## 💗 🏷

📥 🏢 💭 ❔ 🏷 💪 👀 💖 ⏮️ 👫 🔐 🏑 & 🥉 🌐❔ 👫 ⚙️:

=== "🐍 3️⃣.6️⃣ & 🔛"

    ```Python hl_lines="9  11  16  22  24  29-30  33-35  40-41"
    {!> ../../../docs_src/extra_models/tutorial001.py!}

    {!> ../../../docs_src/extra_models/tutorial001_py310.py!}
    ```

### 🔃 `**user_in.dict()`

```Python hl_lines="6  11"
{!../../../docs_src/path_params/tutorial003.py!}
```

Aksi halde, `/users/{user_id}` yolu `"me"` değerinin `user_id` parametresi için gönderildiğini "düşünerek" `/users/me` ile de eşleşir.

Benzer şekilde, bir yol operasyonunu yeniden tanımlamanız mümkün değildir:

```Python hl_lines="6  11"
{!../../../docs_src/path_params/tutorial003b.py!}
```

### 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"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

```Python hl_lines="1  3" title="app/routers/users.py"
{!../../../docs_src/bigger_applications/app/routers/users.py!}
```

### *Pfadoperationen* mit `APIRouter`

Und dann verwenden Sie ihn, um Ihre *Pfadoperationen* zu deklarieren.

Verwenden Sie ihn auf die gleiche Weise wie die Klasse `FastAPI`:

```Python hl_lines="6  11  16" title="app/routers/users.py"

하지만, 만약 모델 내용에 `item `키를 가진 JSON으로 예측하길 원한다면, 추가적인 본문 매개변수를 선언한 것처럼 `Body`의 특별한 매개변수인 `embed`를 사용할 수 있습니다:

```Python hl_lines="17"
{!../../../docs_src/body_multiple_params/tutorial005.py!}
```

아래 처럼:

```Python
item: Item = Body(..., embed=True)
```

이 경우에 **FastAPI**는 본문을 아래 대신에:

```JSON hl_lines="2"
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
