!!! tip "Tipp"
    Wenn Sie eine `HTTPException` auslösen, können Sie dem Parameter `detail` jeden Wert übergeben, der nach JSON konvertiert werden kann, nicht nur `str`.

    Zum Beispiel ein `dict`, eine `list`, usw.

    Das wird automatisch von **FastAPI** gehandhabt und der Wert nach JSON konvertiert.

## Benutzerdefinierte Header hinzufügen

		Status:     "200 OK",
		StatusCode: http.StatusOK,
		Body:       io.NopCloser(&bytes.Buffer{}),
		Request:    req,
	}, nil
}

// MirrorRequest is a round tripper that can be called to get back the calling request as
// the core round tripper in a chain.
var MirrorRequest http.RoundTripper = onewayRoundTripper{}

// NewUpgradeRequestRoundTripper takes two round trippers - one for the underlying TCP connection, and

// a file tree.
//
// After a long discussion on go.dev/issue/46279, we decided the
// best approach was for Go to raise the limit unconditionally for itself,
// and then leave old software to set the limit back as needed.
// Code that really wants Go to leave the limit alone can set the hard limit,
// which Go of course has no choice but to respect.
func init() {
	var lim Rlimit

**FastAPI** verwendet diese *vorübergehende* Response, um die Cookies (auch Header und Statuscode) zu extrahieren und fügt diese in die endgültige Response ein, die den von Ihnen zurückgegebenen Wert enthält, gefiltert nach einem beliebigen `response_model`.

Sie können den `Response`-Parameter auch in Abhängigkeiten deklarieren und darin Cookies (und Header) setzen.
