Wenn Sie mehr über Formularfelder und ihre Kodierungen lesen möchten, besuchen Sie die [<abbr title="Mozilla Developer Network – Mozilla-Entwicklernetzwerk">MDN</abbr>-Webdokumentation für `POST`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST).

/// warning | Achtung

由於 `Response` 常用來設定標頭與 Cookie，FastAPI 也在 `fastapi.Response` 提供了它。

## 自訂標頭 { #custom-headers }

請記住，專有的自訂標頭可以[使用 `X-` 前綴](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers)來新增。

type Source struct {
	Host      string `json:"host"`
	Port      string `json:"port"`
	UserAgent string `json:"userAgent"`
}

// Event represents event notification information defined in
// http://docs.aws.amazon.com/AmazonS3/latest/dev/notification-content-structure.html.
type Event struct {
	EventVersion      string            `json:"eventVersion"`
	EventSource       string            `json:"eventSource"`

이 경우 `myapp.py` 내부의 자동 변수 `__name__`에는 값이 `"__main__"`이 들어가지 않습니다.

따라서 다음 행

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

은 실행되지 않습니다.

## 디버거로 코드 실행 { #run-your-code-with-your-debugger }

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