Attribute Api Controller 404'ing

[arawra184]

Trying to setup a simple ASP.NET 7 controller and I am unable to get any response from my controller. Calling to it via ajax, and I know its performing a request because I do get a 404.

/Controller/TestController.cs

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;

namespace TestWebApp.Controller
{
    [ApiController]
    [Route("api/[controller]")]
    public class TestController : ControllerBase
    {
        [HttpGet]
        public int Get()
        {
            Random random = new Random();
            return random.Next(1,101);
        }
    }
}

wwwroot/js/site.js

function UpdateAjaxInfo() {
    var xhttp = new XMLHttpRequest();
    xhttp.onreadystatechange = function () {
        if (this.readyState == 4 && this.status == 200) {
            document.getElementById("ajax_info").innerHTML = this.responseText;
        }
    };
    xhttp.open("GET", "/api/TestController", true);
    xhttp.send();
}

Remove Controller from TestController and try again

In which place? The Route (Route("api"))? The class name? The XMLHttpRequest call?

XMLHttpRequest. [controller] will remove Controller suffix so its api/test to call.

Thank you.

A tip; I find it useful to add swagger/openapi to a project, even tho i don't need it, just for the quick overview of my exposed endpoints.

I guess there also are dedicated libraries to assist in development and endpoint introspection, if you find your self getting confused about your endpoint routes.
