Routing problems using Asp.net core

Question

When trying to route a core 2.0 application, I can’t get to the controller.

public class GetClientController : Controller
    {
        LoadClient loadClient = new LoadClient();

        [HttpGet]
        public IEnumerable<Cliente> GetCliente(double cpf)
        {
            return loadClient.GetCliente().AsEnumerable().ToList();
        }
    }

In the controller above, the Routeprefix does not roll, I tried these two namespace and did not roll:

using System.Net.Http;
using System.Web.Http;

On my model I did it

[Route("api/getcliente/{cpf}")]
        public List<Cliente> GetCliente(Int64 cpf)
        {
            List<Cliente> cliente = new List<Cliente>();

            cliente.Add(new Cliente(123456, "[email protected]", "986754007", "CB", "EML"));
            cliente.Add(new Cliente(908734, "[email protected]", "988877731", "CB", "SMS"));
            cliente.Add(new Cliente(674300, "[email protected]", "965241131", "PF", "EML"));
            cliente.Add(new Cliente(101654, "[email protected]", "987450101", "EX", "EML"));
            cliente.Add(new Cliente(501274, "[email protected]", "986754144", "PA", "SMS"));

            var lista = cliente
                .Where(cp => cp.Cpf == cpf).ToList();

            return lista;
        }

when I test on Postman, it doesn’t make a mistake, but I don’t get the list passed. This is Postman:

EDIT1

I made this edition and removed from the model and still does not enter the method

public class GetClientController : Controller
    {
        LoadClient loadClient = new LoadClient();

        [HttpGet]
        [Route("api/getcliente/{cpf}")]
        public IEnumerable<Cliente> GetCliente(Int64 cpf)
        {
            return loadClient.GetCliente(cpf).AsEnumerable().ToList();
        }
    }

EDIT3 My Startap.Cs

public class Startup
    {
        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.Run(async (context) =>
            {
                await context.Response.WriteAsync("Hello World!");
            });
        }

EDIT4

I made that change and it still didn’t happen

[Route("api/[controller]")]
    public class GetClientController : Controller
    {
        LoadClient loadClient = new LoadClient();

        [HttpGet("getcliente/{cpf}")]
        public IEnumerable<Cliente> GetCliente(Int64 cpf)
        {
            return loadClient.GetCliente(cpf).AsEnumerable().ToList();
        }
    }

Answer 1

I did. At Startup I did:

public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();
            services.AddRouting();
        }

        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            app.UseMvc();
        }

and in the controller I called

[Route("api/[controller]")]
    public class GetClientController : Controller
    {
        LoadClient loadClient = new LoadClient();

        [HttpGet("{cpf}")]
        public IEnumerable<Cliente> GetCliente(Int64 cpf)
        {
            return loadClient.GetCliente(cpf).AsEnumerable().ToList();
        }
    }

With that I solved the problem. Thank you all.

In Aspnet Core there is no more Annotation RoutePrefix, now both for Class and Action Annotation Route, like you did.

But when you create the route [Route("api/getcliente/{cpf}")], You’re saying the Cpf property will be received somehow. Added to that, you use a [HttpGet], then you want to pass Cpf by the url itself.

Knowing this, the Postman print shows that you are not stating the url correctly.

She should be: http://localhost:55730/api/getclient/31865881384

If Action still does not receive Cpf, it is because you did not make explicit in the parameter that it should be received via url.

To do so make the following change:

public class GetClientController : Controller
{
    LoadClient loadClient = new LoadClient();

    [HttpGet]
    [Route("api/getcliente/{cpf}")]
    public IEnumerable<Cliente> GetCliente([FromRoute]double cpf)
    {
        return loadClient.GetCliente().AsEnumerable().ToList();
    }
}
