### 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**):

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:

        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

## 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] *}

Yukarıdaki bilgileri kullanarak aynı yardımcı fonksiyonla OpenAPI şemasını üretebilir ve ihtiyacınız olan her parçayı override edebilirsiniz.

Örneğin, [özel bir logo eklemek için ReDoc'un OpenAPI extension'ını](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo) ekleyelim.

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

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