ASP.NET MVC: How to create a usable UrlHelper instance?

Question

I am using quartz.net to schedule regular events within asp.net mvc application.

The scheduled job should call a service layer script that requires a UrlHelper instance

Answer 1

You need a RequestContext to create a UrlHelper. In one of my HtmlHelper extension methods, I do it like this:

public static string ScriptUrl(this HtmlHelper html, string script)
{
    var url = new UrlHelper(html.ViewContext.RequestContext);
    ...
}

How you get the RequestContext is dependent on your application.

Edit: Sorry I totally mis-read the question I guess.

It sounds like your scheduler (which I have no idea how it works) is a seperate process and you want the UrlHelper to help generate valid URLs in your MVC app?

You could try writing a handler in your MVC app that will be running under your applications context that will build the URL for you and return it. You could then call the handler from your scheduler to get any URL you need based on the params you pass in. This way your scheduler just needs to know about where the query URL of your MVC app is and then can ask it to do the Url mapping for you.

Hope this is a bit better of an answer. If I am totally off let me know... was going to delete my response but thought I would give it one more shot.

How about just creating a new HttpContext for the UrlHelpler as in this answer:

Answer 4

Remember to specify the protocol parameter when using UrlHelper.Action method, this will generate absolute urls. Example:

url.Action("Action", "Controller", null, "http")

or

url.Action("Action", "Controller", null, request.Url.Scheme)
