/// info | Informação

Para declarar headers, você precisa usar `Header`, caso contrário, os parâmetros seriam interpretados como parâmetros de consulta.

///

## Conversão automática { #automatic-conversion }

`Header` tem algumas funcionalidades a mais em relação a `Path`, `Query` e `Cookie`.

A maioria dos cabeçalhos padrão são separados pelo caractere "hífen", também conhecido como "sinal de menos" (`-`).

    return (format == this) ? str : convert(format, str);
  }

  /** Enum values can override for performance reasons. */
  String convert(CaseFormat format, String s) {
    // deal with camel conversion
    StringBuilder out = null;
    int i = 0;
    int j = -1;
    while ((j = wordBoundary.indexIn(s, ++j)) != -1) {
      if (i == 0) {
        // include some extra space for separators

## Query-Parameter Typkonvertierung { #query-parameter-type-conversion }

Sie können auch `bool`-Typen deklarieren, und sie werden konvertiert:

Você também pode declarar tipos `bool`, e eles serão convertidos:
