How to get the complete request that calls my MVC2 controller?

Question

Newbie question … sorry ;-)

I have to write and to integrate a new website in a complex web application.

My new (MVC2) website will be hosted on a separate server and only called when the user clicks on a link in the already existing, complex website.

Means I(!) define the URL which calls my(!) new website.

But “they” (the calling, already existing, complex web application/website) will add an attribute to the url. This attribute is the sessionID.

Ok, I think I understand already that this calls my (MVC2) controller.

But how can I get in my (MVC2) controller the “calling URL” (which include the added sessionID)?

Hopefully that someone understand what I ask ;-)

Thanks in advance!

I want just share my little parser - hopefully it helps someone. ;-)

Also requests like

(Request.Url.Query =) "?sessionID=12345678901234567890123456789012&argumentWithoutValue&x=1&y&z=3"

will be well parsed. Here my code:

Hashtable attributes = new Hashtable();
string query = Request.Url.Query;

string[] arrPairs = query.Split('&');       // ...?x=1&y=2
if (arrPairs != null)
{
  foreach(string s in arrPairs)
  {
     if (!String.IsNullOrEmpty(s))
     {
        string onePair = s.Replace("?", "").Replace("&", "");

        if (onePair.Contains("="))
        {
          string[] arr = onePair.Split('=');
          if (arr != null)
          {
            if (arr.Count() == 2)
            {
               attributes.Add(arr[0], arr[1]);
            }
          }
        }
        else
        {
          // onePair does not contain a pair!
          attributes.Add(onePair, "");
        }
      }
    }

Answer 1

In your controller you still have direct access to the Request object, so you can use Request.Url, etc.

Does that answer your question, or is it something else that you need?

Answer 2

You really should set your URL and Route to be more MVC-Like. The URL you are calling should be:

newapp/controller/action/sessionId

Then set your route up:

routes.MapRoute(
    "sessionId",
    "{controller}/{action}/{sessionId}",
    new { controller = "controller", action = "action", sessionId = 0 });

Then in your controller:

public ActionResult Action(int sessionId)
{

}
