I am developing REST API application in ASP.NET MVC3. I am trying to get client client HOST Name in action but cannot success. I am using this API in multiple applications so I want to log the domain name.
Link 1
HttpContext.Current.Request.UserHostAddress;
System.Web.HttpContext.Current.Request.UserHostName;
System.Web.HttpContext.Current.Request.UserHostAddress;
Link 2
private string GetClientIp(HttpRequestMessage request)
{
if (request.Properties.ContainsKey("MS_HttpContext"))
{
return ((HttpContextWrapper)request.Properties["MS_HttpContext"]).Request.UserHostAddress;
}
else if (request.Properties.ContainsKey(RemoteEndpointMessageProperty.Name))
{
RemoteEndpointMessageProperty prop;
prop = (RemoteEndpointMessageProperty)request.Properties[RemoteEndpointMessageProperty.Name];
return prop.Address;
}
else
{
return null;
}
}
All these options providing IP address but i want to get host name
API Controller www.myapi.com
public class TESTController : ApiController
{
public TESTController()
{
}
[HttpGet]
public object Add(string data = "")
{
try
{
string result = "0";
if (!string.IsNullOrEmpty(data))
{
//should be www.myapiconsume.com
var host = System.Web.HttpContext.Current.Request.UserHostName;
var ip = System.Web.HttpContext.Current.Request.UserHostAddress;
}
return new { response = result };
}
catch (Exception ex)
{
throw ex;
}
}
}
Calling API Action from different domain www.myapiconsume.com
public class HomeController : Controller
{
public ActionResult Index()
{
var url = "http://myapi.com/api/test/add?data={0}";
url = string.Format(url, "{ data}");
WebClient client = new WebClient();
var result = client.DownloadString(url);
return Content(result);
}
}
How can i get this?
You can use Dns.GetHostEntry Method to reverse look up.
public static string ReverseLookup(string ip)
{
if (String.IsNullOrWhiteSpace(ip))
return ip;
try
{
IPHostEntry host = Dns.GetHostEntry(ip);
return host != null ? host.HostName : ip;
}
catch (SocketException)
{
return ip;
}
}
