  Optional routes

  Nov 23, 2019 08:33 PM|islaboy|LINK

  
  How can I make a route that accepts optional path or sub directory. Something like this:
  
  this would be a valid route 
  {path}/go
  {path}/run
  {path}stop
  
  and so is this which also point to a same controller and action as above.<br>
  /go
  /run
  /stop
  
  

  routes.MapRoute(
name: "Go",
url: "go",
defaults: new { controller = "Controller", action = "Go", id = UrlParameter.Optional }
);

  routes.MapRoute(
name: "Go",
url: "path/go",
defaults: new { controller = "Controller", action = "Go", id = UrlParameter.Optional }
);

  so basically i'm avoiding to write it twice like this.

  This requires custom code to make a decision.  The convention is {controller}/{action} which maps to  {class}/{method}.  The framework tries to find the Controller then an Action within the controller.  

  You could write custom route middleware that looks for an Action when the controller is not found.  I do not recommend this approach.  Just create a Go, Run, and Stop controller.

  One of possible option to handle this is Route Constraint, you need to register a route constraint and each time route matches you will check the valid path and if you return true this route get executed otherwise you can do some other action.

  We cannot solve our problems with the same thinking we used when we created them.
