How to add controller endpoints to Razor Server in ASP.NET Core 7.0 / VS2022-CodePudding

I am trying to add a controller with routing to a Razor server-side app. I tried several things but I only see solutions for .NET 6 and cannot figure it out.

I created a controller like this:

using Microsoft.AspNetCore.Mvc;

namespace SAAR.Controllers
{
    [ApiController]
    [Route("settings/[controller]")]
    public class ConfigurationController : ControllerBase
    {
        public ConfigurationController()
        {
        }

        [HttpGet("test")]
        public string Test()
        {
            return "Test a controller in Razor";
        }
    }
}

Then in my program.cs I added:

builder.Services.AddControllers();

and

app.UseEndpoints(endpoints => {
    endpoints.MapRazorPages();
    endpoints.MapControllers();
});

AFAIK this should work and the endpoint http://localhost:5000/settings/test should be there but I get a http 404 error.

What am I doing wrong?

Here my complete program.cs:

using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Web;
using Microsoft.EntityFrameworkCore;
using SAAR.Areas.Identity;
using SAAR.Data;
using SAAR.Services;
using SAAR.Settings;
using System.Configuration;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
var connectionString = builder.Configuration.GetConnectionString("DefaultConnection") ?? throw new InvalidOperationException("Connection string 'DefaultConnection' not found.");

builder.Services.AddDbContext<ApplicationDbContext>(options =>
    options.UseSqlServer(connectionString));

builder.Services.AddDatabaseDeveloperPageExceptionFilter();

// Add MVC Controllers
builder.Services.AddControllers();
builder.Services.AddRazorPages();

builder.Services.AddServerSideBlazor();
builder.Services.AddTransient<IEmailSender, EmailSender>();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseMigrationsEndPoint();
}
else
{
    app.UseExceptionHandler("/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();

app.MapControllers();
app.MapBlazorHub();
app.MapFallbackToPage("/_Host");

app.UseEndpoints(endpoints => {
    endpoints.MapRazorPages();
    endpoints.MapControllers();
});

app.Run();

Thanks for any help...

CodePudding user response：

You cannot use routing / MVC-controllers in an Razor Server web app.

CodePudding user response：

In your case,the uri should be http://localhost:5000/settings/Configuration

The name of your controller is Configuration not test

[ApiController]
[Route("settings/[controller]")]
public class ConfigurationController : ControllerBase
{
 .....
}
