MVC4 Web API Rest interface with Multiple Parameters
It seems you are missing the action in your request (/api/Login/KeyValue/CodeValue/UserValue/PasswordValue
).
Try /api/Login/Get/KeyValue/CodeValue/UserValue/PasswordValue
instead, if you intend to use the first route.
If you want to be able to call it without the action specified and default to "Get", you have to specify a default action:
defaults: new { Key = UrlParameter.Optional, Code = UrlParameter.Optional, UserID = UrlParameter.Optional, Password = UrlParameter.Optional, Action = "Get" }
I have successfully tried this in an ASP.NET MVC 4 project (Visual Studio 2012 RC):
Creating a LoginController with action:
public string Get(string Key, string Code, string UserID, string Password)
{
return Key + Code + UserID + Password;
}
And mapping the route in Global.asax.cs:
RouteTable.Routes.MapHttpRoute(null, "api/{controller}/{Key}/{Code}/{UserID}/{Password}",
new { Key = UrlParameter.Optional, Code = UrlParameter.Optional, UserID = UrlParameter.Optional, Password = UrlParameter.Optional, Action = "Get"});
If it is not working for you, maybe another route is catching the request or the route is not being registered.

I have a controller named LoginController with a Get method with a signature of:
public string Get(string Key, string Code, string UserID, string Password)
I want to be be able to invoke it with a call similar to:
http://localhost:1234/api/Login/KeyValue/CodeValue/UserValue/PasswordValue
I cannot get this to work. If I invoke the call with:
http://localhost:1234/api/Login?Key=KeyValue&Code=CodeValueUserID=UserValue&Password=PasswordValue
The call is successful.
I've tried adding routes such as below to Global.asax
routes.MapHttpRoute(name: "Login", routeTemplate: "api/{controller}/{action}/{Key}/{Code}/{UserID}/{Password}", defaults: new { Key = UrlParameter.Optional, Code = UrlParameter.Optional, UserID = UrlParameter.Optional, Password = UrlParameter.Optional });
or
routes.MapHttpRoute(name: "Login", routeTemplate: "api/{controller}/{Key}/{Code}/{UserID}/{Password}", defaults: new { Key = UrlParameter.Optional, Code = UrlParameter.Optional, UserID = UrlParameter.Optional, Password = UrlParameter.Optional });
These do not seem to work. Where am I going wrong or is this even possible? I was able to do this in the RC version of WebApi with MVC3.

keitn over 11 yearsI'm in agreement, I need to expose an API to a third party so the format is out of my control. I've tried what you suggested but neither approach works (adding GET or specifying default action). I also tried adding [HttpGet] to the controller label.

keitn over 11 yearsYou're correct. I mistakenly added a RegisterRoutes method to Global.asax (as in MVC3), once I added it in RouteConfig.cs all it works fine. Thanks.
