Node.js 请求 - 无法解码 HTML 页面

Question

我正在尝试使用 Node.js 和 Request 模块解码此 HTML 页面：http://www.receita.fazenda.gov.br/PessoaJuridica/CNPJ/cnpjreva/Cnpjreva_Erro.asp

javascript 控制台 returns 字符集 windows-1252:

document.characterSet = "windows-1252";

我尝试使用 iconv-lite 中的所有可用编码，但所有 return 都是错误的文本。

var body = iconv.decode(new Buffer(body), "windows1252");

有人知道如何解码此页面吗？

示例代码：

request('http://www.receita.fazenda.gov.br/PessoaJuridica/CNPJ/cnpjreva/Cnpjreva_Erro.asp', function (err, res, body) {
    var body = iconv.decode(new Buffer(body), "windows1252");    
    console.log(body);
});

Returns:

...
<td valign="middle" align="left"><b><font face="Arial" size="2">
        Acesso n�o permitido.
</td>
...

解码后的字符串应该是：

...
<td valign="middle" align="left"><b><font face="Arial" size="2">
        Acesso não permitido.
</td>
...

谢谢。

这个代码

var request = require('request');

request('http://www.receita.fazenda.gov.br/PessoaJuridica/CNPJ/cnpjreva/Cnpjreva_Erro.asp', function (err, res, body) {
  console.log(body);
});

输出页面

<script language="JavaScript">
  function proxima(link)
  {
   location.replace(link);
   return false;
  }
  function carrega(vobjeto) {
     for (var va = 0 ; va < document.forms[0].elements.length; va++) {
        if (document.forms[0].elements[va].name == vobjeto) {
            document.forms[0].elements[va].focus();
        }
     }
     return false;
  }
  function volta(vvolta) {
     history.go(vvolta*-1);
     return false;
  }
  function SaltaCampo (campo, prox, tammax, teclapres)
{
   var tecla = teclapres.keyCode;
   vr = campo.value;
   tam = vr.length;
   if (tecla != 0 && tecla != 10 && tecla != 24)
      if (tam == tammax)
          prox.focus();
}
</script>

Answer 2

页面returns使用document.characterSet的编码是错误的，正确的编码是ISO-8859-1

body = iconv.decode(body, "ISO-8859-1");
