我正在使用ASP.Net MVC core 2.1开发应用程序，在该应用程序中，我不断遇到以下异常。
“ InvalidOperationException：没有为方案'CookieSettings'注册任何身份验证处理程序。注册的方案为：Identity.Application，Identity.External，Identity.TwoFactorRememberMe，Identity.TwoFactorUserId。您是否忘记了调用AddAuthentication（）。AddSomeAuthHandler？ “
我遍历文章做了必要的更改，但例外情况保持不变。我不知道下一步该怎么做。
以下是我的 startup.cs ：
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
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<Infrastructure.Data.ApplicationDbContext>(options =>
options.UseSqlServer(
Configuration.GetConnectionString("DefaultConnection")));
services.AddDefaultIdentity<IdentityUser>()

login / signin.cs：

{
ViewData["ReturnUrl"] = returnUrl;
if (ModelState.IsValid)
{
// This doesn't count login failures towards account lockout
// To enable password failures to trigger account lockout, set lockoutOnFailure: true
ApplicationUser signedUser = await _userManager.FindByEmailAsync(model.Email);
if (signedUser != null)
{
var result = await _signInManager.PasswordSignInAsync(signedUser.UserName, model.Password, model.RememberMe, lockoutOnFailure: false);
if (result.Succeeded)
{
//Authorize login user
if (!string.IsNullOrEmpty(signedUser.UserName))
{
await AuthorizeUser(signedUser);
}
_logger.LogInformation(1, "User logged in.");
HttpContext.Session.SetString("UserName", model.Email);
int AccountTypeId = _contactManagement.GetContactDetailsByUserId(signedUser.Id).UserAccountTypeId;
HttpContext.Session.SetString("AccountTypeId", AccountTypeId.ToString());
return RedirectToLocal(returnUrl);
}
else
{
if (_userManager.SupportsUserLockout && await _userManager.GetLockoutEnabledAsync(signedUser))
{
await _userManager.AccessFailedAsync(signedUser);
}
}
if (result.RequiresTwoFactor)
{
return RedirectToAction(nameof(SendCode), new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
}
if (signedUser.LockoutEnd != null)
{
_logger.LogWarning(2, "User account locked out.");
return View("Lockout");
}
else
{
ViewBag.InvalidPassword = "Password is Invalid";
ModelState.AddModelError(string.Empty, "Invalid login attempt.");
return View(model);
}
}
else
{
ViewBag.InvalidEmail = "Email is Invalid";
return View(model);
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
我尝试将登录方法更改为下面的方法，但没有成功，非常感谢您的帮助
List<Claim> userClaims = new List<Claim>
{
new Claim(applicationUser.Id, Convert.ToString(applicationUser.Id)),
new Claim(ClaimTypes.Name, applicationUser.UserName),
new Claim(ClaimTypes.Role, Convert.ToString(applicationUser.Id))
};
var identity = new ClaimsIdentity(userClaims, CookieAuthenticationDefaults.AuthenticationScheme);
await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme,new ClaimsPrincipal(identity));
答案 0 :(得分：0)
您应该在Startup.cs类的ConsigureServices方法中添加以下说明。您可以在方法开始时添加它：
services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
.AddCookie(o =>
{
o.Cookie.Name = options.CookieName;
o.Cookie.Domain = options.CookieDomain;
o.SlidingExpiration = true;
o.ExpireTimeSpan = options.CookieLifetime;
o.TicketDataFormat = ticketFormat;
o.CookieManager = new CustomChunkingCookieManager();
});
