Question

I am working on SMS send and receive functionality in an MVC3 application. How can I send a response to a URL? Any URL that hits my page should get a response like “ok” or “received”.

For example, consider the code below, which is sent from a provider to my site. I need to send a response text like “ok” or received to stringResult. If I can respond to URL with some “success” parameter that would be great.

string stringResult = null;
stringpost ="parameters for url";
objWebRequest = (HttpWebRequest)WebRequest.Create("http://myip/app/action/receivesms?");
objWebRequest.Method = "POST"
if ((objProxy1 != null))
{
    objWebRequest.Proxy = objProxy1;
}

objWebRequest.ContentType = "applicationwww-form-urlencoded";

objStreamWriter = new StreamWriter(objWebRequest.GetRequestStream());
objStreamWriter.Write(stringpost);
objStreamWriter.Flush();
objStreamWriter.Close();

objWebResponse = (HttpWebResponse)objWebRequest.GetResponse();
objStreamReader = new StreamReader(objWebResponse.GetResponseStream());
stringResult = objStreamReader.ReadToEnd();
objStreamReader.Close();
return (stringResult);

Just do this in your controller:

public ActionResult YourAction()
{
    return Content("OK");
}

Or, if you wanted to use HTTP codes instead of strings, you could do something like:

public ActionResult YourAction()
{
    // 204 is the HTTP code for OK with no content
    return new HttpStatusCodeResult(204);
}
