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 :

# FastAPI { #fastapi }

<style>
.md-content .md-typeset h1 { display: none; }
</style>

<p align="center">
  <a href="https://fastapi.tiangolo.com/es"><img src="https://fastapi.tiangolo.com/img/logo-margin/logo-teal.png" alt="FastAPI"></a>
</p>
<p align="center">
    FastAPI framework, alto rendimiento, fácil de aprender, rápido de programar, listo para producción
</p>
<p align="center">

Por exemplo, vamos adicionar [Extensão OpenAPI do ReDoc para incluir um logo personalizado](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo).

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

Primeiro, escreva toda a sua aplicação **FastAPI** normalmente:

///

## 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] *}

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] *}

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:

### Es testen { #check-it }

Sobald Sie auf [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc) gehen, werden Sie sehen, dass Ihr benutzerdefiniertes Logo verwendet wird (in diesem Beispiel das Logo von **FastAPI**):

///

## 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] *}
