使用idWhois组件处理.com域时，我得到错误的信息。以下是通过idWhois收到的stackoverflow.com数据示例

Whois Server Version 2.0

对于这两个请求，我使用服务器whois.verisign-grs.com。我试着放置＆＃34; =＆＃34;在域名之前，但这没有帮助。这里是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;

这里的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

.COM域名支持许多注册商现在拥有自己的WHOIS规定，如输出中所述：

现在可以注册.com和.net域中的域名许多不同的竞争注册商。有关详细信息，请访问internic.net 信息。

您将获得WHOIS服务器以在初始响应中进行查询：

Whois Server: whois.name.com

因此，您需要执行两次WHOIS查询，一次针对Verisign，其中包含.COM域名的初始记录，另一次针对注册商WHOIS。

Answer 2

问题不在于TIdWhois，它正在做与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只是返回服务器发送的任何内容。
