Asp.NET Core 2身份验证. SignInManager.PasswordSignInAsync()成功，但是User.Identity.IsAuthenticated为false [英] Asp.NET Core 2 Authentication. SignInManager.PasswordSignInAsync() succeeds, but User.Identity.IsAuthenticated is false

问题描述

我正在关注IdentityUser上的一些教程，我认为我的操作与教程中的完全相同，但是当我尝试登录时，即使您_signInManager成功，我也会收到"MyIdentity:False"(使用LogInformation)，这似乎很奇怪.我试图将用户设置为已确认，但没有结果.

I was following some tutorials on IdentityUser, and I think I did exactly as in tutorials, but when I try to login, I get "MyIdentity: False" (with LogInformation) even thou _signInManager succeeds, which seems to be very weird. I tried to set the users as confirmed, but with no result.

我正在Mac上使用Visual Studio.

I'm working on Visual Studio on Mac.

这是我注册用户的方式:

Here's how I register my users:

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Register(RegisterViewModel model)
{
    if (ModelState.IsValid)
    {
        var user = new ApplicationUser()
        {
            UserName = model.Email,
            Email = model.Email
        };
        var result = await _userManager.CreateAsync(user, model.Password);

        if (result.Succeeded)
        {
            await _signInManager.SignInAsync(user, false);
            return this.RedirectToAction("Index", "Home");
        }
        else
        {
            foreach (var error in result.Errors)
                ModelState.AddModelError("", error.Description);
        }   
    }

    return View(model);
}

这是我尝试登录的方式:

And here's how I try to login:

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Login(LoginViewModel model)
{
    if (ModelState.IsValid)
    {
        var result = await _signInManager.PasswordSignInAsync(
            model.Email,
            model.Password,
            model.RememberMe,
            lockoutOnFailure: false
        );

        if (result.Succeeded)
        {
            _logger.LogInformation("MyIdentity: " + User.Identity.IsAuthenticated);
            return this.RedirectToAction("Index", "Home");
        }

        ModelState.AddModelError("", "Invalid Login attempt.");
    }
    return View(model);
}

这是我为其配置服务的方式:

Here's how I configure the services for it:

services.AddDbContext<CmagruDBContext>(options =>
    options.UseSqlite("Data Source=Cmagru.db",
        b => b.MigrationsAssembly("Presentation")));

services.AddIdentity<ApplicationUser, IdentityRole>()
    .AddEntityFrameworkStores<CmagruDBContext>()
    .AddDefaultTokenProviders();
services.Configure<IdentityOptions>(options =>
{
    options.Password.RequireDigit = false;
    options.Password.RequiredLength = 3;
    options.Password.RequireLowercase = false;
    options.Password.RequireNonAlphanumeric = false;
    options.Password.RequireUppercase = false;
    options.User.RequireUniqueEmail = true;
});
services.ConfigureApplicationCookie(options =>
{
    options.Cookie.HttpOnly = true;
    options.ExpireTimeSpan = TimeSpan.FromMinutes(30);
    options.LoginPath = "/Account/Login";
    options.AccessDeniedPath = "/Account/AccessDenied";
    options.SlidingExpiration = true;
});

我在配置中确实有app.UseAuthentication();

推荐答案

对于其他可能遇到此问题的人: 就我而言，我只需要在Configure()中的app.UseMvc()之前放置app.UseAuthentication();.否则，它对我不起作用.

For other people who may encounter this problem: In my case, I had to simply put app.UseAuthentication(); before app.UseMvc() in Configure(). Otherwise, it doesn't work for me.

我想我在文档中错过了.

I think I missed that in documentation.
