Defining a route for self hosting in .Net Standard

Question

User360451555 posted

Hi, i cant seem to figure out what should be the route defined to reach my post method in a self-hosting website. It's running .Net Standard and eventually it will run as a windows service. 

Here is how i have tried to structure the routing table

public static void Main(string[] args)
        {

            var config = new HttpSelfHostConfiguration(new Uri("http://localhost:43634"));

            config.Routes.MapHttpRoute("API Default", "api/{controller}/{id}", new { id = RouteParameter.Optional });

            InitPrintEngine();

            using (HttpSelfHostServer server = new HttpSelfHostServer(config))
            {
                server.OpenAsync().Wait();
                Console.WriteLine("Press Enter to quit.");
                Console.ReadLine();
            }
        }

    [Route("[api/controller]")]
    public class LabelController : ApiController
    {
        [System.Web.Mvc.HttpGet]
        public IEnumerable<string> Get()
        {
            return new[] {"Label1", "Label2"};
        }

        [System.Web.Mvc.HttpPost, Route("label/labelvariables")]
        public async Task<HttpResponseMessage> PostFile(HttpPostedFile labelFile)
        {

         }
    }

I've omitted the details of the PostFile method to have it as simple as possible. I cant reach the method though through postman. 

This is how am trying to invoke the method

http://localhost:43634/api/Label/labelvariables/labelFile

Hi feiyim ,

Your route could be modified like :

    [RoutePrefix("api/Label")]
    public class LabelController : ApiController
    {
        [System.Web.Mvc.HttpGet]
        public IEnumerable<string> Get()
        {
            return new[] { "Label1", "Label2" };
        }

        [Route("labelvariables")]
        public async Task<string> PostValues()
        {
            return "";
        }
    }

So that you can post to  "http://localhost:xxxxx/api/Label/labelvariables" .
