c# - 在 ASP.NET 中获取服务器的 IP 地址？

Question

如何获取调用我的 ASP.NET 页面的服务器的 IP 地址？我见过关于 Response 对象的东西，但在 c# 中我很新。万分感谢。

这应该有效：

 //this gets the ip address of the server pc

  public string GetIPAddress()
  {
     IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName()); // `Dns.Resolve()` method is deprecated.
     IPAddress ipAddress = ipHostInfo.AddressList[0];

     return ipAddress.ToString();
  }

或者

 //while this gets the ip address of the visitor making the call
  HttpContext.Current.Request.UserHostAddress;

Request.ServerVariables["LOCAL_ADDR"];

这为多宿主服务器提供了请求进入的 IP

上面的方法很慢，因为它需要一个 DNS 调用（如果一个不可用，显然不会工作）。您可以使用下面的代码获取当前 pc 的本地 IPV4 地址及其相应子网掩码的映射：

public static Dictionary<IPAddress, IPAddress> GetAllNetworkInterfaceIpv4Addresses()
{
    var map = new Dictionary<IPAddress, IPAddress>();

    foreach (var ni in NetworkInterface.GetAllNetworkInterfaces())
    {
        foreach (var uipi in ni.GetIPProperties().UnicastAddresses)
        {
            if (uipi.Address.AddressFamily != AddressFamily.InterNetwork) continue;

            if (uipi.IPv4Mask == null) continue; //ignore 127.0.0.1
            map[uipi.Address] = uipi.IPv4Mask;
        }
    }
    return map;
}

警告：这还没有在 Mono 中实现

  //this gets the ip address of the server pc
  public string GetIPAddress()
  {
     string strHostName = System.Net.Dns.GetHostName();
     //IPHostEntry ipHostInfo = Dns.Resolve(Dns.GetHostName()); <-- Obsolete
     IPHostEntry ipHostInfo = Dns.GetHostEntry(strHostName);
     IPAddress ipAddress = ipHostInfo.AddressList[0];

     return ipAddress.ToString();
  }

这适用于 IPv4：

public static string GetServerIP()
{            
    IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName());

    foreach (IPAddress address in ipHostInfo.AddressList)
    {
        if (address.AddressFamily == AddressFamily.InterNetwork)
            return address.ToString();
    }

    return string.Empty;
}

下面的快照取自Mkyong以在谷歌浏览器中显示开发人员控制台内的网络选项卡。在“请求标头”选项卡中，您可以看到所有服务器变量的列表，如下所示：

下面是几行代码，它们获取访问您的应用程序的客户端的 IP 地址

//gets the ipaddress of the machine hitting your production server              
string ipAddress = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; 

if (ipAddress == "" || ipAddress == null)  
{                                     
  //gets the ipaddress of your local server(localhost) during development phase                                                                         
  ipAddress = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];              
}

//Output:                                                                           
For production server - 122.169.106.247 (random)
For localhost         - ::1
