dotnet核心授权始终重定向到身份默认登录页面

Question

I create custom login page in pages/login.cshtml , and also i set [authorize] config in startup.cs to redirect to /login , but it keep redirect to Identity/Account/Login .

this is my startup.cs

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<ApplicationDbContext>(options =>
                options.UseSqlServer(
                    Configuration.GetConnectionString("DefaultConnection")));

            services.AddDefaultIdentity<IdentityUser>()
                .AddEntityFrameworkStores<ApplicationDbContext>()
                .AddDefaultTokenProviders();

            services.Configure<IdentityOptions>(options =>
            {
                // Password settings.
                options.Password.RequireDigit = true;
                options.Password.RequireLowercase = true;
                options.Password.RequireNonAlphanumeric = true;
                options.Password.RequireUppercase = true;
                options.Password.RequiredLength = 6;
                options.Password.RequiredUniqueChars = 1;

                // Lockout settings.
                options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(5);
                options.Lockout.MaxFailedAccessAttempts = 5;
                options.Lockout.AllowedForNewUsers = true;

                // User settings.
                options.User.AllowedUserNameCharacters =
                "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-._@+";
                options.User.RequireUniqueEmail = false;
            });



            services.ConfigureApplicationCookie(options =>
            {
                // Cookie settings
                options.Cookie.HttpOnly = true;
                options.ExpireTimeSpan = TimeSpan.FromMinutes(5);

                options.LoginPath = "/Login";
                options.AccessDeniedPath = "/AccessDenied";
                options.LogoutPath = "/Logout";
                options.ReturnUrlParameter = CookieAuthenticationDefaults.ReturnUrlParameter;
                options.SlidingExpiration = true;
            });

            services.AddMvc()
                .SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
                .AddRazorPagesOptions(options =>
                {
                    options.Conventions.AddPageRoute("/Dashboards/Dashboard1", "");
                    options.Conventions.AllowAnonymousToPage("/Login");
                });


        }

I already specify loginpath = "/login" , but it always back to identity default page, why and how to solve it?

For this issue, try services.PostConfigure<CookieAuthenticationOptions> like

services.AddDefaultIdentity<IdentityUser>()
    .AddEntityFrameworkStores<ApplicationDbContext>();
services.AddMvc()
    .SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
    .AddRazorPagesOptions(options =>
    {
        options.Conventions.AddPageRoute("/Dashboards/Dashboard1", "");
        options.Conventions.AllowAnonymousToPage("/Login");
    });
services.PostConfigure<CookieAuthenticationOptions>(IdentityConstants.ApplicationScheme,
    opt => {
        //configure your other properties
        opt.LoginPath = "/Login";
    });
