How to get IpAddress and UserAgent in ASP.NET Web API get methods

Question

I am using ASP.NET Web Api to expose a few GET methods.

But before I return the data I need to log a couple of details to the db, of which few of them are as listed below :

Caller's Ip
Caller's User Agent
Caller's Used Url

Now in the controller when I used to do this I used to use the following code,

var ipAddress = Request.ServerVariables["REMOTE_ADDR"];
var userAgent = Request.UserAgent;

But here in Web API I am unable to use this.

Can anyone please help me out with this.

I figured it out,

public static LogModel GetApiLogDetails()
{
    var logModel = new LogModel();
    logModel.TimeStamp   = DateTime.Now;
    logModel.CallerIp    = HttpContext.Current.Request.UserHostAddress;
    logModel.CallerAgent = HttpContext.Current.Request.UserAgent;
    logModel.CalledUrl   = HttpContext.Current.Request.Url.OriginalString;
    return logModel;
}

I would try and avoid HttpContext as it only works in WebHost. – Darrel Miller Jun 28 '13 at 15:02

@DarrelMiller: Since this question has come up many times, do you think Web API should have an extension on HttpRequestMessage to get the client IP address? Like the System.Web.Http.WebHost and System.Web.Http.Owin.Selfhost can create request message extensions which users could use. – Kiran Jun 28 '13 at 17:28
@KiranChalla It would be a fairly low impact change that would definitely help a lot of people. – Darrel Miller Jun 28 '13 at 17:54

You should use HttpRequestMessage class, that conteins all data you need.
