Todo o processo que era aplicado para parâmetros de rota também é aplicado para parâmetros de consulta:

* Suporte do editor (obviamente)
* <abbr title="convertendo uma string que vem de um request HTTP em um dado Python">"Parsing"</abbr> de dados
* Validação de dados
* Documentação automática

## Valores padrão

Como os parâmetros de consulta não são uma parte fixa da rota, eles podem ser opcionais e podem ter valores padrão.

	if err := scanner.Err(); err != nil {
		fmt.Printf("Invalid input: %s", err)
	}
	// Output:
	// 1234
	// 5678
	// Invalid input: strconv.ParseInt: parsing "1234567901234567890": value out of range
}

// Use a Scanner with a custom split function to parse a comma-separated
// list with an empty final value.
func ExampleScanner_emptyFinalToken() {
	// Comma-separated list; last entry is empty.
	const input = "1,2,3,4,"
