asp.net core web api center routing - asp.net-mvc-routing

Question

I have an issue related with asp.net core center routing. I know we could use Attribute Routing, but I did not find anything related with center routing like asp.net web api.
Something like below:
routes.MapHttpRoute(
name: "API Default",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
Could you share me how to achieve above function in asp.net core? If there is no built-in function, could custom routing service achieve this?
Regards,
Edward

Answer 1

center routing is supported for web api, but we need to disable attribute route on web api.
Route:
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
routes.MapRoute(
name: "api",
template: "api/{controller=Values}/{action=GetAll}/{id?}");
});
Web API controller:
//[Route("api/[controller]")]
//[Authorize]
public class ValuesController : Controller
{
private ApplicationDbContext _db;
public ValuesController(ApplicationDbContext db)
{
_db = db;
}
// GET: api/values
//[HttpGet]
public IEnumerable<string> GetAll()
{
var result = from user in _db.UserInfos
select user.UserName;
return result.ToList();
//return new string[] { "value1", "value2" };
}
// GET api/values/5
//[HttpGet("{id}")]
public string GetById(int id)
{
var result = from user in _db.UserInfos
select user.UserName;
return result.FirstOrDefault();
//return User.Identity.IsAuthenticated.ToString(); //"value";
}
}

You can configure the routes as options to MVC middleware. Add the routes to the configure method in your startup class
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
app.UseMvc(routes =>
{
routes.MapRoute("blog", "api/{*article}",
defaults: new { controller = "Blog", action = "Article" });
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
}
Note that in ASP.NET, the controller are same for both MVC and API. Its an unified model.
