在razor页面应用程序中路由到apicontroller?

我创建了一个ASP.NET核心剃须刀页面应用程序(ASP.NET版)。它的工作正常,与正常的网页,但我也想要一个附注器,如本教程: https://docs.microsoft.com/en-us/aspnet/core/tutorials/web-api-vsc?view=aspnetcore-2.1

但是,当我创建我的控制器就像上面的例子一样,每当我试图达到它时,我得到一个404页。

创业班有没有我错过的东西?

public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });

            services.AddDbContext<DomainDbContext>(opt => opt.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        }

        // 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();
            }
            else
            {
                app.UseExceptionHandler("/Error");
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseCookiePolicy();

            app.UseMvc();
        }

我的助手类:

    [Route("api/[controller]")]
    [ApiController]
    class DomainController : ControllerBase 
    {
        private readonly DomainDbContext _context;

        public DomainController (DomainDbContext context) 
        {
            _context = context;
        }

        [HttpGet]
        public ActionResult<List<Domain>> GetAll()
        {
            return new List<Domain> {new Domain() {Name ="Hello", Tld = ".se", Expiration = DateTime.UtcNow.AddDays(35)}};
        }
}

据我所见,一切都像指南,但显然有些地方是不正确的,因为我得到404的所有页面。即使我创建了一个新的方法,但它并没有真正达到预期的效果,而且是无法实现的。

我尝试过的主要途径是 /api/domain 是的。

提前谢谢你的帮助!
