C# SEO:为.SE域工作的whois服务器?

C# SEO:为.SE域工作的whois服务器?,c#,whois,C#,Whois,我正在开发一个小型域检查器,但无法使.SE正常工作: public string Lookup(string domain, RecordType recordType, SeoToolsSettings.Tld tld) { TcpClient tcp = new TcpClient(); tcp.Connect(tld.WhoIsServer, 43); string strDomain = recordType.ToString() + " " + domain +

我正在开发一个小型域检查器,但无法使.SE正常工作:

public string Lookup(string domain, RecordType recordType, SeoToolsSettings.Tld tld)
{
    TcpClient tcp = new TcpClient();
    tcp.Connect(tld.WhoIsServer, 43);
    string strDomain = recordType.ToString() + " " + domain + "\r\n";
    byte[] bytDomain = Encoding.ASCII.GetBytes(strDomain.ToCharArray());
    Stream s = tcp.GetStream();
    s.Write(bytDomain, 0, strDomain.Length);
    StreamReader sr = new StreamReader(tcp.GetStream(), Encoding.ASCII);
    string strLine = "";
    StringBuilder builder = new StringBuilder();
    while (null != (strLine = sr.ReadLine()))
    {
        builder.AppendLine(strLine);
    }
    tcp.Close();
    if (tld.WhoIsDelayMs > 0) System.Threading.Thread.Sleep(tld.WhoIsDelayMs);
    return builder.ToString();
}
我已经尝试了whois服务器whois.nic-se.se和whois.iis.se,我一直得到:

"domain google.se" not found.
编辑:

我试着换成UTF8,但没有其他结果

当我尝试从系统内部使用whois时,我得到了正确的结果,但我的代码没有,甚至没有使用SE.whois-servers.net

Hmmm,在我的Mac上做
whois google.se
时,我得到以下信息:

所以这可能只是你的代码。也许您必须使用非ASCII编码来执行请求,例如UTF8?

我终于解决了这个问题

使用wireshark,我看到来自sysinternals的whois没有添加“域”部分:

字符串strDomain=recordType.ToString()+“”+域+“\r\n”

(recordType.ToString==“域”)


所以当我移除它时,它就起作用了

不查看您的代码为什么不:

示例@

对于
par.se

IP Found:

Host name:

Aliases:

如果您只需要IP的成熟信息,也可以使用我的页面进行测试

您的代码是否适用于其他TLD的whois服务器?我在Win7上使用Sysinternals
whois google.se
获得了正确的输出是的,我的代码适用于其他TLD。我将whois.internic.net用于.com域,这很好用。嗯。。。将尝试使用其他编码。。。但是有没有可能确定你在mac上使用的服务器是谁?请注意,我已经让它在whois服务器whois.internic.net的.com域中工作。
