asp.net-core – .net核心自定义身份验证中的User.Identity.IsAuthenticated始终为false

任何人都可以检查下面的代码,让我知道为什么我总是假的(User.Identity.IsAuthenticated)??我正确地在浏览器上获取cookie
能够从Claim获得价值,但“User.Identity.IsAuthenticated”总是错误的.

public async Task<IActionResult> Login(string phoneNumber,int otp,string returnUrl)
    {
        if (this.accountService.ValidateOTP(phoneNumber,otp))
        {
            var claims = new List<Claim>
            {
                new Claim(ClaimTypes.MobilePhone,phoneNumber),new Claim(ClaimTypes.Name,phoneNumber)
            };
            var userIdentity = new ClaimsIdentity();
            userIdentity.AddClaims(claim);
            ClaimsPrincipal userPrincipal = new ClaimsPrincipal(userIdentity);

            await HttpContext.Authentication.SignOutAsync("MyCookieMiddlewareInstance");
            await HttpContext.Authentication.SignInAsync("MyCookieMiddlewareInstance",userPrincipal,new AuthenticationProperties
                {
                    ExpiresUtc = DateTime.UtcNow.AddMinutes(20),IsPersistent = false,AllowRefresh = false
                });

            if (string.IsNullOrWhiteSpace(returnUrl))
            {
                return RedirectToAction("Create","Ad");
            }
            else
            {
                return Redirect(returnUrl);
            }
        }

        return BadRequest();
    }

解决方法

当ClaimsIdentity.AuthenticationType为null或为空时,ClaimsIdentity.IsAuthenticated返回false.为避免这种情况,请停止使用无参数的ClaimsIdentity构造函数并使用接受authenticationType参数的重载：

var userIdentity = new ClaimsIdentity("Custom");
