  No action was found on the controller 'User' that matches the request.

  Hi,

  This is my first Project in web api. I am creating web api  for User Login

  In my web api 2 Controller like as follows

  using MyServices.Models;
  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Net;
  using System.Net.Http;
  using System.Web.Http;
  
  namespace MyServices.Controllers
  {
      public class UserController : ApiController
      {
          [Route("api/User")]
          [HttpGet]
          public HttpResponseMessage AppLogin(String userName, String passWord)
          {
  
              Admin_AppUserBLL objusr = Admin_AppUserBLL.GetAdmin_AppUserBLL(userName);
  
              if (objusr != null)
              {
                  if (objusr.Password == passWord)
                  {
                      objusr.Message = "valid username";
                  }
                  else
                  {
                      objusr = new Admin_AppUserBLL();
                      objusr.Message = "username or password is invalid";
                      objusr.Status = 0;
                  }
              }
              else
              {
                  objusr = new Admin_AppUserBLL();
                  objusr.Message = "username or password is invalid";
                  objusr.Status = 0;
              }
              //return objusr.ToString();//
              HttpResponseMessage res = Request.CreateResponse(HttpStatusCode.OK, objusr);
              return res;
          }
        
      }
  
  }
  

  While consuming this service

  http://localhost:50007/api/User/AppLogin?userName=123&passWord=123

  It shows error like No action was found on the controller 'User' that matches the request.

  In my webApiConfig

  public static void Register(HttpConfiguration config)
  {
  // Web API configuration and services

  // Web API routes
  config.MapHttpAttributeRoutes();

  // config.Routes.MapHttpRoute(
  // name: "DefaultApi",
  // routeTemplate: "api/{controller}/{id}",
  // defaults: new { id = RouteParameter.Optional }
  //);

  I Have tried like as follows, but still same issue

  // config.Routes.MapHttpRoute(
  // name: "AppLogin",
  // routeTemplate: "api/{User}/{name}/{password}",
  // defaults: new { name = RouteParameter.Optional, password = RouteParameter.Optional }
  // );
  }

  How to solved it

  // routeTemplate: "api/{User}/{name}/{password}",

  You have mismatch in parameter name. Change your Route configuration like below

  public static void Register(HttpConfiguration config)
          {
              // Web API routes
              config.MapHttpAttributeRoutes();
              //Customized ROute
              config.Routes.MapHttpRoute(
                  name: "AppLogin",
                  routeTemplate: "api/{controller}/{userName}/{passWord}",
                  defaults: new { name = RouteParameter.Optional, password = RouteParameter.Optional }
              );
              //Default Route
              config.Routes.MapHttpRoute(
                  name: "DefaultApi",
                  routeTemplate: "api/{controller}/{id}",
                  defaults: new { id = RouteParameter.Optional }
              );
          }

  After this change you can access your webapi method like below

  http://localhost:8089/api/User?userName=YourUserNameValue&passWord=YourPasswordValue
