ASP.NET Core razor 视图未在浏览器中显示

Question

这是浏览器显示给我的：

这是我的 _Layout:

@using Microsoft.AspNetCore.Mvc.Localization
@inject IViewLocalizer _localizer

我要求用户进行身份验证并重定向到 ConfigureServices 中的身份验证页面。

    services.AddAuthorization(options =>
            {
                options.FallbackPolicy = new AuthorizationPolicyBuilder()
                    .RequireAuthenticatedUser()
                    .Build();
            });

    services.ConfigureApplicationCookie(options =>
            {
                options.LoginPath = "/Authentication";
                options.SlidingExpiration = true;
            });

AuthenticationController:

    public class AuthenticationController : Controller
    {
        private readonly IAuthenticationBL _authenticationBL;

        public AuthenticationController(IAuthenticationBL authenticationBL)
        {
            _authenticationBL = authenticationBL;
        }

        public IActionResult Index()
        {
            return View();
        }

        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<IActionResult> Register([Bind("Email", "Password")] AuthenticationVM vm)
        {
            if (!ModelState.IsValid) return View("Index", vm);
            await _authenticationBL.RegisterAsync(vm.Email, vm.Password, Request);
            return RedirectToAction("Index", "GeneralInformation");
        }

        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<IActionResult> LogIn([Bind("Email", "Password")] AuthenticationVM vm)
        {
            if (!ModelState.IsValid) return View("Index", vm);
            await _authenticationBL.LogInAsync(vm.Email, vm.Password, User);
            return RedirectToAction("Index", "GeneralInformation");
        }

        public async Task<IActionResult> LogOut()
        {
            await _authenticationBL.LogoutAsync(User);
            return RedirectToAction("Index");
        }
    }

身份验证索引视图：

@model Web.Models.VMs.AuthenticationVM
@inject IViewLocalizer _localizer
@using Microsoft.AspNetCore.Mvc.Localization

@{
    ViewData["Title"] = "Authentication";
}

<div class="card w-50 container justify-content-center">
    <div class="card-body">
        <h5 class="text-center mb-3">@_localizer["Log in"]</h5>
        <form asp-controller="Authentication" id="authentication-form">
            <div asp-validation-summary="ModelOnly" class="text-danger"></div>
            <div class="form-floating mb-4 row">
                <input asp-for="Email" class="form-control" placeholder="Email" autocomplete="email">
                <label asp-for="Email">@_localizer["Email"]</label>
                <span asp-validation-for="Email" class="text-danger"></span>
            </div>
            <div class="form-floating mb-4 row">
                <input asp-for="Password" class="form-control" placeholder="Password">
                <label asp-for="Password">@_localizer["Password"]</label>
                <i class="btn fa-solid fa-eye" id="password-toggle"></i>
                <span asp-validation-for="Password" class="text-danger"></span>
            </div>
            <div class="row justify-content-between">
                <button type="submit" class="col-sm-5 btn btn-primary" asp-action="Register">@_localizer["Register"]</button>
                <button type="submit" class="col-sm-5 btn btn-primary" asp-action="LogIn">@_localizer["Log in"]</button>
            </div>
        </form>
    </div>
</div>

@section Scripts {
    <script src="~/js/authentication.js"></script>
}

问题是我在Startup中删除了默认操作的指示：

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        "default",
        "{controller=Home}/{action}");
});

框架无法理解在重定向到控制器时调用什么操作，我没有获得页面。修正：

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        "default",
        "{controller=Home}/{action=Index}");
});
