FastAPI 通过 Pydantic 模型的 `.dict()` 配合 <a href="https://docs.pydantic.dev/latest/concepts/serialization/#modeldict" class="external-link" target="_blank">该方法的 `exclude_unset` 参数</a> 来实现此功能。

///

/// info

你还可以使用：

* `response_model_exclude_defaults=True`
* `response_model_exclude_none=True`

    Pods["Pods"]
    CNI --Programs--> Z
    CNI --Watches--> Pods
    Z --Runs Within--> Pods
    CNIP --Calls--> CNI
```

The CNI Plugin is a binary installed as a [CNI plugin](https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/network-plugins/) on the node.
The container runtime is responsible for invoking this when a Pod is being started (before the containers run).

你将看到如下的 JSON 响应：

```JSON
{"message": "Hello World"}
```

### 交互式 API 文档

跳转到 <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>。

你将会看到自动生成的交互式 API 文档（由 <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a> 提供）：

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Então, vá para a interface `/docs`, você verá que o **FastAPI** está usando esses **modelos** para **documentar** a API, e ele também os usará para **serializar** e **validar** os dados.

<div class="screenshot">

```JSON
{"item_id": 5, "q": "somequery"}
```

A typical platform builds on other platforms in order to add more capabilities, for example, to add support for a particular language.
