{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[1,4,7:9] *}

### Generate the OpenAPI schema { #generate-the-openapi-schema }

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

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[2,15:21] *}

### Modify the OpenAPI schema { #modify-the-openapi-schema }

### 一般的 **FastAPI** { #normal-fastapi }

先照常撰寫你的 **FastAPI** 應用：

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[1,4,7:9] *}

### 產生 OpenAPI 結構 { #generate-the-openapi-schema }

接著，在 `custom_openapi()` 函式內，使用相同的工具函式來產生 OpenAPI 結構：

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[2,15:21] *}

### 修改 OpenAPI 結構 { #modify-the-openapi-schema }

現在可以加入 ReDoc 擴充，在 OpenAPI 結構的 `info`「物件」中新增自訂的 `x-logo`：

### 通常の **FastAPI** { #normal-fastapi }

まず、通常どおりに **FastAPI** アプリケーションを実装します:

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[1,4,7:9] *}

### OpenAPI スキーマの生成 { #generate-the-openapi-schema }

次に、`custom_openapi()` 関数内で同じユーティリティ関数を使って OpenAPI スキーマを生成します:

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[2,15:21] *}

### OpenAPI スキーマの変更 { #modify-the-openapi-schema }

from fastapi import FastAPI
from fastapi.openapi.utils import get_openapi

app = FastAPI()


@app.get("/items/")
async def read_items():
    return [{"name": "Foo"}]


def custom_openapi():
    if app.openapi_schema:
        return app.openapi_schema
    openapi_schema = get_openapi(
        title="Custom title",
        version="2.5.0",
        summary="This is a very custom OpenAPI schema",

### 常规 **FastAPI** { #normal-fastapi }

首先，像平常一样编写你的 **FastAPI** 应用：

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[1,4,7:9] *}

### 生成 OpenAPI 架构 { #generate-the-openapi-schema }

然后，在一个 `custom_openapi()` 函数中使用同一个工具函数生成 OpenAPI 架构：

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[2,15:21] *}

### 修改 OpenAPI 架构 { #modify-the-openapi-schema }

现在你可以添加 ReDoc 扩展，在 OpenAPI 架构的 `info` “对象”中加入自定义 `x-logo`：

### Сгенерируйте схему OpenAPI { #generate-the-openapi-schema }

Затем используйте ту же вспомогательную функцию для генерации схемы OpenAPI внутри функции `custom_openapi()`:

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[2,15:21] *}

### Измените схему OpenAPI { #modify-the-openapi-schema }

Önce, tüm **FastAPI** uygulamanızı her zamanki gibi yazın:

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[1,4,7:9] *}

### OpenAPI Şemasını Üretme { #generate-the-openapi-schema }

Ardından, bir `custom_openapi()` fonksiyonunun içinde aynı yardımcı fonksiyonu kullanarak OpenAPI şemasını üretin:

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[2,15:21] *}

### OpenAPI Şemasını Değiştirme { #modify-the-openapi-schema }

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[1,4,7:9] *}

### Згенерувати схему OpenAPI { #generate-the-openapi-schema }

Далі використайте ту ж утилітарну функцію для генерації схеми OpenAPI всередині функції `custom_openapi()`:

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[2,15:21] *}

### Змінити схему OpenAPI { #modify-the-openapi-schema }

### Générer le schéma OpenAPI { #generate-the-openapi-schema }

Ensuite, utilisez la même fonction utilitaire pour générer le schéma OpenAPI, dans une fonction `custom_openapi()` :

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[2,15:21] *}

### Modifier le schéma OpenAPI { #modify-the-openapi-schema }

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[1,4,7:9] *}

### Das OpenAPI-Schema generieren { #generate-the-openapi-schema }

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

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[2,15:21] *}

### Das OpenAPI-Schema ändern { #modify-the-openapi-schema }
