Delphi idWhois错误数据

Question

在使用idWhois组件处理.com域时，我得到了错误的信息。以下是通过stackoverflow.com的idWhois接收的数据的示例

Whois Server Version 2.0

Domain names in the .com and .net domains can now be registered
with many different competing registrars. Go to internic.net
for detailed information.

   Domain Name: STACKOVERFLOW.COM

   Sponsoring Registrar IANA ID: 625
   Whois Server: whois.name.com
   Referral URL: name.com

对于这两个请求，我都使用了服务器whis.verisign-grs.com。我尝试将"=“放在域的前面，但这没有帮助。下面是Delphi代码

W := TIdWhois.Create(nil);
W.ReadTimeout := 10000;
W.ConnectTimeout := 10000;
try
  W.Host := 'whois.verisign-grs.com';
  if Zone = 'com' then
    Result := W.WhoIs('=' + Domain)
  else
    Result := W.WhoIs(Domain);
except end;
W.Free;

以下是PHP代码

function QueryWhoisServer($whoisserver, $domain) {
  $port = 43;
  $timeout = 15;
  $fp = @fsockopen($whoisserver, $port, $errno, $errstr, $timeout) or die("Socket Error " . $errno . " - " . $errstr);
  if($whoisserver == "whois.verisign-grs.com") $domain = "=".$domain; 
  fputs($fp, $domain . "\r\n");
  $out = "";
  while(!feof($fp)){
      $out .= fgets($fp);
  }
  fclose($fp);

  $res = "";
  if((strpos(strtolower($out), "error") === FALSE) && (strpos(strtolower($out), "not allocated") === FALSE)) {
      $rows = explode("\n", $out);
      foreach($rows as $row) {
          $row = trim($row);
          if(($row != '') && ($row{0} != '#') && ($row{0} != '%')) {
              $res .= $row."\n";
          }
      }
  }
  return $res;
}

谢谢

Answer 1

WHOIS域现在支持许多具有自己的WHOIS域的注册商，如输出中所述：

.com和.net域名中的

域名现在可以向许多不同的竞争注册商注册。有关详细信息，请访问internic.net。

您可以在初始响应中查询WHOIS服务器：

Whois Server: whois.name.com

因此，您将需要执行两次WHOIS查找，一次是针对包含.COM域初始记录的Verisign，另一次是针对注册商WHOIS。

Answer 2

问题不在TIdWhois，而是在做与PHP脚本完全相同的事情：

function TIdWHOIS.WhoIs(const ADomain: string): string;
begin
  Connect; try
    IOHandler.WriteLn(ADomain);
    Result := IOHandler.AllData;
  finally Disconnect; end;
end;

TIdWhois只是按原样返回服务器发送的任何内容。
