## 覆寫預設行為 { #overriding-the-defaults }

基於上述資訊，你可以用相同的工具函式來產生 OpenAPI 結構，並覆寫你需要客製的部分。

例如，我們要加入 [ReDoc 的 OpenAPI 擴充，插入自訂 logo](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo)。

### 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] *}

labels.login.title=Login
labels.index_label=Label
labels.index_lang=Preferred Language
labels.index_sort=Sort
labels.index_num=Display Count
labels.logout_title=Logout
labels.logout=Logout
labels.do_you_want_to_logout=Do you want to logout?
labels.logout_button=Logout
labels.profile=Change Password
labels.administration=Administration
labels.profile_button=Settings
labels.profile.title=Settings
labels.profile.update=Update

        description="Here's a longer description of the custom **OpenAPI** schema",
        routes=app.routes,
    )
    openapi_schema["info"]["x-logo"] = {
        "url": "https://fastapi.tiangolo.com/img/logo-margin/logo-teal.png"
    }
    app.openapi_schema = openapi_schema
    return app.openapi_schema

For example, let's add [ReDoc's OpenAPI extension to include a custom logo](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo).

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

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

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

Par exemple, ajoutons [l’extension OpenAPI de ReDoc pour inclure un logo personnalisé](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo).

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

Tout d’abord, écrivez votre application **FastAPI** comme d’habitude :

Por ejemplo, vamos a añadir [la extensión OpenAPI de ReDoc para incluir un logo personalizado](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo).

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

Primero, escribe toda tu aplicación **FastAPI** como normalmente:

		</c:if>
		<li class="nav-item" data-toggle="tooltip" data-placement="left"
			title="<la:message key="labels.tooltip_logout" />"><a class="nav-link" href="${contextPath}/logout" aria-label="<la:message key="labels.tooltip_logout" />"><i class="fa fa-sign-out-alt" aria-hidden="true"></i></a></li>
	</ul>

    val requestBody =
      MultipartBody
        .Builder()
        .setType(MultipartBody.FORM)
        .addFormDataPart("title", "Square Logo")
        .addFormDataPart(
          "image",
          "logo-square.png",
          File("docs/images/logo-square.png").asRequestBody(MEDIA_TYPE_PNG),
        ).build()

    val request =
      Request
        .Builder()

///

## 覆盖默认值 { #overriding-the-defaults }

基于以上信息，你可以用同一个工具函数生成 OpenAPI 架构，并按需覆盖其中的各个部分。

例如，让我们添加 [ReDoc 的 OpenAPI 扩展以包含自定义 Logo](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo)。

### 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] *}
