No HTTP resource was found that matches the request URI 'http://localhost:85476/API/EmployeeMobile/GetEmployeeForMobile,
No action was found on the controller 'EmployeeMobile' that matches the request.
My controller:
public class EmployeeMobileController : ApiController
{
private PCommon _pCommon;
IEmployeeBusiness _employeeBusiness;
Mapper _mapper;
public EmployeeMobileController()
{
_pCommon = new PCommon();
_employeeBusiness = new EmployeeBusiness();
_mapper = new Mapper();
}
[HttpPost]
public string GetEmployeeForMobile(string userID, string connectionString)
{
DataSet dsEmployee = _employeeBusiness.GetAllEmployeeForMobile(Guid.Parse(userID), connectionString);
JavaScriptSerializer json_serializer = new JavaScriptSerializer();
object routes_list = (object)json_serializer.DeserializeObject(JsonConvert.SerializeObject(dsEmployee.Tables[0]));
return JsonConvert.SerializeObject(routes_list);
}
}
My WebApiConfig.cs
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}

Please note, WebAPI doesn't support binding of multiple POST parameters. You are defining your POST like a GET method. Change it to return a single Model
Your model should look like following.
public class Input
{
public string uSerID { get; set; }
public string connectionString { get; set; }
}
Now change the POST method like
[HttpPost]
public string GetEmployeeForMobile(Input request)
{
//Your implementation here
}
and you JSON for the post should look like following.
{uSerID:"abc", connectionString :"xyz"}
