客户端的.Net Core JWT API实现

Question

.Net Core是我的新手，并且面临以下问题。

我有Authentication_API，该API返回 JWT令牌 到客户端的登录控制器。 成功登录后，我想重定向到主页，但是当我对控制器使用[Authorize]属性时，它不起作用，但是如果没有[Authorize]属性，它将显示主页。

请帮助我如何解决此问题。 我想我没有在令牌中保存令牌。

我引用了以下JWT API signal code

这是我的令牌生成器

var tokenHandler = new JwtSecurityTokenHandler();
                    var key = Encoding.ASCII.GetBytes(_appSettings.Secret);
                    var tokenDescriptor = new SecurityTokenDescriptor
                    {
                        Subject = new ClaimsIdentity(new Claim[]
                        {
                                new Claim(ClaimTypes.Name, user.UserId.ToString()),
                                new Claim(ClaimTypes.Role,user.Role.RoleNameE.ToString())
                        }),
                        Expires = DateTime.UtcNow.AddDays(7),
                        SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(key), SecurityAlgorithms.HmacSha256Signature)
                    };
                    var token = tokenHandler.CreateToken(tokenDescriptor);
                    var tokenString = tokenHandler.WriteToken(token);

此后，我想重定向到首页

这是我的“启动”页面

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.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);


            // Add ASPNETCore DBContext services.
            services.AddDbContext<Tejoury_MSContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DatabaseConnection")));

            // configure strongly typed settings objects : abdulla
            var appSettingsSection = Configuration.GetSection("AppSettings");
            services.Configure<AppSettings>(appSettingsSection);

            //--------------- configure jwt(JSON Web Tokens) authentication : abdulla --------------- 
            var appSettings = appSettingsSection.Get<AppSettings>();
            var key = Encoding.ASCII.GetBytes(appSettings.Secret);
            services.AddAuthentication(x =>
            {
                x.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
                x.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
            })
            .AddJwtBearer(x =>
            {
                x.Events = new JwtBearerEvents
                {
                    OnTokenValidated = context =>

                        var userService = context.HttpContext.RequestServices.GetRequiredService<IUserService>();
                        var userId = int.Parse(context.Principal.Identity.Name);
                        var user = userService.GetById(userId);
                        if (user == null)
                        {
                            // return unauthorized if user no longer exists
                            context.Fail("Unauthorized");
                        }
                        return Task.CompletedTask;
                    }
                };
                x.RequireHttpsMetadata = false;
                x.SaveToken = true;
                x.TokenValidationParameters = new TokenValidationParameters
                {
                    ValidateIssuerSigningKey = true,
                    IssuerSigningKey = new SymmetricSecurityKey(key),
                    ValidateIssuer = false,
                    ValidateAudience = false
                };
            });
            //----------------------------------------------------------------------

            // configure DI for application services : Abdulla
            services.AddScoped<IUserService, UserService>();
            services.AddAuthorization(options =>
            {
                options.AddPolicy("RequireAdminRole",
                    authBuilder =>
                    { authBuilder.RequireRole("Admin"); });

            });

        }
