Question

我想使用JwtAuthentication。我在Startup.cs类中进行了一些设置。并将一个控制器设置为[授权]，但是当我调用该控制器的响应是404而不是401时，为什么？当我调用控制器生成令牌时，它生成成功，但由于某种原因也不能在邮递员中使用他，再次我得到错误404。你知道为什么吗？

        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)

            app.UseAuthentication();
            app.UseMvc();
        }
    }
}

生成令牌只是隐藏在

中的私有方法

 [HttpPost]
    [ActionName("login")]
    public async Task<Object> Login([FromBody] LoginResource login)
    {
        var result = await _signInManager.PasswordSignInAsync(login.Email, login.Password, false, false);
        if (result.Succeeded)
        {
            var appUser = _userManager.Users.SingleOrDefault(r => r.Email == login.Email);
            return  GenerateJwtToken(login.Email, appUser);
        }
        throw new ApplicationException("INVALID_LOGIN_ATTEMPT");
    }

    private  object GenerateJwtToken(string email, IdentityUser user)
    {
        var claims = new List<Claim>
        {
            new Claim(JwtRegisteredClaimNames.Sub, email),
            new Claim(JwtRegisteredClaimNames.Jti, Guid.NewGuid().ToString()),
            new Claim(ClaimTypes.NameIdentifier, user.Id)
        };

        var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_configuration["JwtKey"]));
        var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);
        var expires = DateTime.Now.AddDays(Convert.ToDouble(_configuration["JwtExpireDays"]));

        var token = new JwtSecurityToken(
            _configuration["JwtIssuer"],
            _configuration["JwtIssuer"],
            claims,
            expires: expires,
            signingCredentials: creds
        );

        return new JwtSecurityTokenHandler().WriteToken(token);
    }

使用 services.AddIdentityCore<ApplicationUser> 而不是 services.AddIdentity<ApplicationUser, IdentityRole> 应该可以解决这个问题。请注意，使用 AddIdentityCore 包含角色没有重载：

<块引用>

默认情况下不添加角色服务，但可以使用 AddRoles() 添加。

(^ 来自documentation for AddIdentityCore)

这可以这样实现：

services.AddIdentityCore<ApplicationUser>(config =>
            {
                config.Password.RequireDigit = false;
                config.Password.RequiredLength = 4;
                config.Password.RequireLowercase = false;
                config.Password.RequireNonAlphanumeric = false;
                config.Password.RequireUppercase = false;
            })
                .AddEntityFrameworkStores<ApplicationDbContext>()
                .AddDefaultTokenProviders()
                .AddRoles<IdentityRole>();

UseJwtBearerAuthentication返回404而不是401
