Asp net core routing multiple parameters

Question

I am trying to route asp.net core application.

I have having this scenario:

[Route("/{user}")]
public IActionResult FirstAction(string user)
{
    // Code
}

[Route("/{user}/{project}")]
public IActionResult SecondAction(string user, string project)
{
    // Code 2
}

Problem i am having is that when user goes to link /something it fires both methods (// Code 1 and // Code 2) but i want only first one to fire.

How can i achieve this?

Umm, it shouldn't be possible for 2 actions to run? Could you look at the actual request URL within the action through e.g. HttpContext.Request? — juunas

I do not want multiple actions, i just want multiple parameters to be passed without using ?user=. Same behavior as on github.com/{organization}/{project} — Aleksa Ristic

That's why my answer. The ?user is replaced with the rest path /users — Dario Griffo

Use a better REST API routing

[Route("/users/{user}")]

[Route("/users/{user}/projects/{project}")]

I want same behavior as on github.com/{organization}/{project}

Is that also the API route? Or you are taking about the one in the browser? Because the one in the browser is managed in another place

It is browser route

But your question is about an API route? In that case they are different. And you can maintain a different routing convention from what the user sees and what happens with a backend server... The browser route can be manipulated in many different ways. But for the API I keep my suggestion of the answer I provided

Are you sure that both actions are fired? Which version of ASP NET Core are you using?

I tested the following:

    [HttpGet("/{user}")]
    public ActionResult<string> Test1(string user)
    {
        return "User " + user;
    }

    [HttpGet("/{user}/{project}")]
    public ActionResult<string> Test2(string user, string project)
    {
        return "User " + user + " Project " + project;
    }

The routes where explicit. If there was only one string Test1 was routed. If there were two strings Test2 was routed.

Furthermore, please note the following: If you put a leading / into the route any prefixes will be ignored.
