### 带有额外元数据的多文件上传

和之前的方式一样, 您可以为 `File()` 设置额外参数, 即使是 `UploadFile`:

{* ../../docs_src/request_files/tutorial003_py39.py hl[16] *}

// early instead of silently corrupting data.

### Einen *Pfad-Parameter* deklarieren { #declare-a-path-parameter }

Dann erstellen Sie einen *Pfad-Parameter*, der als Typ die gerade erstellte Enum-Klasse hat (`ModelName`):

{* ../../docs_src/path_params/tutorial005_py39.py hl[16] *}

### Die API-Dokumentation testen { #check-the-docs }

Weil die erlaubten Werte für den *Pfad-Parameter* nun vordefiniert sind, kann die interaktive Dokumentation sie als Auswahl-Drop-Down anzeigen:

        attributeOptions.add(38);
        attributeOptions.add(5);
        attributeOptions.add(color & 0xff);
        return this;
    }

    public Ansi fgRgb(int color) {
        return fgRgb(color >> 16, color >> 8, color);
    }

    public Ansi fgRgb(int r, int g, int b) {
        attributeOptions.add(38);
        attributeOptions.add(2);
        attributeOptions.add(r & 0xff);
