ASP.NET CORE MVC IDENTITY 如何更改默认登录页面的 url？

Question

I have authentification using Identity. But if I use [Authorize] atribute, I`m redirected to localhost:7174/Identity/Account/Login?ReturnUrl=%2FUser%2FUser while I don't have such page. How to change this url? I didn't find any methods or properties that can change that. Also, I added that Identity pages with Scaffold. But even now it said that it's impossible to reach such page. What should I better do?

I don't know what could be usefull for you, so here is my program.cs

using DreamWeb.Models;
using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;


var builder = WebApplication.CreateBuilder(args);

builder.Services.AddMvc();
builder.Services.AddControllersWithViews(); 
builder.Services.AddScoped<IUserService, UserService>();
builder.Services.AddDbContext<DreamsContext>(options =>
    options.UseSqlServer("server = SCAT\\SQLEXPRESS; database = dreams_web; Trusted_Connection=True ; MultipleActiveResultSets = true"));
builder.Services.AddDefaultIdentity<UserAccount>(options => options.SignIn.RequireConfirmedAccount = true)
    .AddEntityFrameworkStores<DreamsContext>();
builder.Services.AddAuthentication().AddCookie();


builder.Services.Configure<IdentityOptions>(options =>
{
    options.SignIn.RequireConfirmedPhoneNumber = false;
    options.SignIn.RequireConfirmedEmail = false;
    options.SignIn.RequireConfirmedAccount = false;

    options.Password.RequireUppercase = false;
    options.Password.RequireDigit = false;
    options.Password.RequiredLength = 1;
    options.Password.RequireLowercase = false;
    options.Password.RequireNonAlphanumeric = false;
});

var app = builder.Build();

if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Home/Error");
    app.UseHsts();
}

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

app.UseRouting();

app.UseAuthorization();

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

If you look here in the documentation there seems to be an option you can pass in on startup that allows you to set that url names "loginUrl"

UserInteraction LoginUrl, LogoutUrl, ConsentUrl, ErrorUrl, DeviceVerificationUrl Sets the URLs for the login, logout, consent, error and device verification pages.

so reasonably you should be able to do

public void ConfigureServices(IServiceCollection services)
{
    ...
    var builder = services.AddIdentityServer(
      options =>
        {
            ...
            options.loginUrl = "myLoginUrl"
        }
    );
    ...
}

About changing default login path. The best way I've found is changing it with CookieAuthenticationOptions in my program.cs:

builder.Services.PostConfigure<CookieAuthenticationOptions>(IdentityConstants.ApplicationScheme, options =>
{
    options.LoginPath = "/SignIn";
});

Attempts to change it in other way (with identity server) had no success.

This helped me: Setting login path within ASP.NET Core 2.2 MVC and Identity .

As for second question (about Identity scaffolded pages, that cant be reached), I was missing this in my program.cs:

app.MapRazorFiles();
