따라서 다음 행

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

은 실행되지 않습니다.

## 디버거로 코드 실행

코드에서 직접 Uvicorn 서버를 실행하고 있기 때문에 디버거에서 직접 Python 프로그램(FastAPI 애플리케이션)을 호출할 수 있습니다.

예를 들어 Visual Studio Code에서 다음을 수행할 수 있습니다.

FastAPI is built on top of **Pydantic**, and I have been showing you how to use Pydantic models to declare requests and responses.

But FastAPI also supports using <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> the same way:

```Python hl_lines="1  7-12  19-20"
{!../../../docs_src/dataclasses/tutorial001.py!}
```

    * 存储在内存的文件超出最大上限时，FastAPI 会把文件存入磁盘；
* 这种方式更适于处理图像、视频、二进制文件等大型文件，好处是不会占用所有内存；
* 可获取上传文件的元数据；
* 自带 <a href="https://docs.python.org/zh-cn/3/glossary.html#term-file-like-object" class="external-link" target="_blank">file-like</a> `async` 接口；
* 暴露的 Python <a href="https://docs.python.org/zh-cn/3/library/tempfile.html#tempfile.SpooledTemporaryFile" class="external-link" target="_blank">`SpooledTemporaryFile`</a> 对象，可直接传递给其他预期「file-like」对象的库。

有时，我们要覆盖 `Request` 与 `APIRoute` 类使用的逻辑。

尤其是中间件里的逻辑。

例如，在应用处理请求体前，预先读取或操控请求体。

!!! danger "危险"

    本章内容**较难**。

    **FastAPI** 新手可跳过本章。

## 用例

常见用例如下：

* 把 <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a> 等非 JSON 请求体转换为 JSON
* 解压 gzip 压缩的请求体
* 自动记录所有请求体的日志

## 处理自定义请求体编码

下面学习如何使用自定义 `Request` 子类压缩 gizp 请求。

并在自定义请求的类中使用 `APIRoute` 子类。

docs/ja/docs/tutorial/request-forms.md

!!! info "情報"
    `Form`は`Body`を直接継承するクラスです。

!!! tip "豆知識"
    フォームのボディを宣言するには、明示的に`Form`を使用する必要があります。なぜなら、これを使わないと、パラメータはクエリパラメータやボディ（JSON）パラメータとして解釈されるからです。

## 「フォームフィールド」について

HTMLフォーム（`<form></form>`）がサーバにデータを送信する方法は、通常、そのデータに「特別な」エンコーディングを使用していますが、これはJSONとは異なります。

**FastAPI** は、JSONの代わりにそのデータを適切な場所から読み込むようにします。
