Question

What am I doing wrong? The does not hit the action and the error is a 405 – >The HTTP verb POST used to access path “somepath” is not allowed.

Client Script

 $.post('/DecisionPoint/ApplicationState', { fileName: fileName, stateString: e });

filename is just a ‘string’ as is ‘e’

Controller Action

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult SaveApplicationState(string fileName, string stateString)
{
            string filePath = GetDpFilePath(fileName);
            HtmlDocument htmlDocument = new HtmlDocument();
            htmlDocument.Load(filePath);
            HtmlNode stateScriptNode =
                htmlDocument.DocumentNode.SelectSingleNode("/html/head/script[@id ='applicationState']");
            stateScriptNode.InnerHtml = "var applicationStateJSON =" + stateString;
            htmlDocument.Save(filePath);

            return Json("State Updated");


}

UPDATE

This is my global.asax.

 routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
        );

        routes.MapRoute(
          "DecisionPoint", // Route name
          "{controller}/{action}/{fileName}/{stateString}", // URL with parameters
          new { controller = "DecisionPoint", action = "ApplicationState", fileName = UrlParameter.Optional, stateString = UrlParameter.Optional} // Parameter defaults
      );

The error is now – Resource not found. The script lives in the standard /Scripts folder that the template creates.

Answer 1

Are you sure this is your path to the control and action?

Controllers/DecisionPoint/SaveApplicationState

Because normally the word “Controllers” doesn’t show up in the URL path, and that is what jQuery needs the exact URL path for accessing this action.

Try just this:

string url = "/DecisionPoint/SaveApplicationState/" + filename + "/" + e;
jQuery.post(url);

The problem is you have mapped the route to an exact URL, so in order to post to that action, you need to recreate the URL. Also please note, I don’t know if this is intentionally or not, but you action name is SaveApplicationState however in the route mapping you have the action listed as ApplicationState. This needs to be consistent.
