### Inclure un *chemin d'accès* { #include-a-path-operation }

Nous pouvons également ajouter des *chemins d'accès* directement à l'application `FastAPI`.

Ici, nous le faisons ... juste pour montrer que nous le pouvons 🤷 :

* 在 OpenAPI 的*路径操作*中为响应添加**JSON Schema**。
    * 它会被**自动文档**使用。
    * 它也会被自动客户端代码生成工具使用。
* 使用 Pydantic 将返回数据**序列化**为 JSON。Pydantic 使用**Rust**编写，因此会**快很多**。

但更重要的是：

* 它会将输出数据**限制并过滤**为返回类型中定义的内容。
    * 这对**安全性**尤为重要，下面会进一步介绍。

## `response_model` 参数 { #response-model-parameter }

在一些情况下，你需要或希望返回的数据与声明的类型不完全一致。
