Et une réponse avec un code HTTP `200` qui utilise votre `response_model`, mais inclut un `example` personnalisé :

```Python hl_lines="20-31"
{!../../docs_src/additional_responses/tutorial003.py!}
```

Tout sera combiné et inclus dans votre OpenAPI, et affiché dans la documentation de l'API :

        assertEquals("010203", StringUtil.toHex(new byte[] { 1, 2, 3 }));
    }

    /**

    @Test
    public void testToHex2() throws Exception {

    }

**FastAPI**将保留来自 `responses` 的附加信息，并将其与模型中的JSON Schema结合起来。

例如，您可以使用状态码 `404` 声明响应，该响应使用`Pydantic`模型并具有自定义的` description` 。

以及一个状态码为 `200` 的响应，它使用您的 `response_model` ，但包含自定义的 `example` ：

```Python hl_lines="20-31"
{!../../docs_src/additional_responses/tutorial003.py!}
```

所有这些都将被合并并包含在您的OpenAPI中，并在API文档中显示：

## 联合预定义响应和自定义响应

您可能希望有一些应用于许多路径操作的预定义响应，但是你想将不同的路径和自定义的相应组合在一块。
