Encore une fois, cela convertira les types de données, les validera, permettra de générer la documentation, etc...

## Paramètres multiples body et query

Bien entendu, vous pouvez déclarer autant de paramètres que vous le souhaitez, en plus des paramètres body déjà déclarés.

type annotationParam struct {
	key        string
	defaultVal string
	validator  annotationValidationFunc
}

func alwaysValidFunc(value string) error {
	return nil
}

func validateInterceptionMode(mode string) error {
	switch mode {
	case redirectModeREDIRECT:
	case redirectModeTPROXY:
	default:

	if err != nil {
		t.Fatalf("MinIO %s: Failed to create an anonymous request.", instanceType)
	}

	// ExecObjectLayerAPIAnonTest - Calls the HTTP API handler using the anonymous request, validates the ErrAccessDeniedResponse,
	// sets the bucket policy using the policy statement generated from `getReadOnlyBucketStatement` so that the

## Escrevendo Templates

Então você pode escrever um template em `templates/item.html`, por exemplo:

```jinja hl_lines="7"
{!../../docs_src/templates/templates/item.html!}
```

### Interpolação de Valores no Template

No código HTML que contém:

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}

...aparecerá o `id` obtido do "context" `dict` que você passou:

```Python
{"id": id}
