JWT 身份验证.Net core [授权] 属性被控制器忽略

Question

我正在尝试在具有 Angular 8 前端和 .Net Core 后端的应用程序中实现基于 JWT 的身份验证。我已经添加了

 app.UseAuthentication();
 app.UseAuthorization();

和

services.AddAuthentication(opt =>

在启动类中。我使用属性装饰了控制器方法[Authorize]。但是，当我尝试在没有任何令牌的情况下点击控制器方法时，它允许进入控制器方法。

启动

public class Startup
    {
        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)
        {
            var jwtSettings = Configuration.GetSection("JwtSettings");
            services.AddAuthentication(opt =>
            {
                opt.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
                opt.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
            }).AddJwtBearer(options =>
            {
                options.TokenValidationParameters = new TokenValidationParameters
                {
                    ValidateIssuer = true,
                    ValidateAudience = true,
                    ValidateLifetime = true,
                    ValidateIssuerSigningKey = true,
                    ValidIssuer = jwtSettings.GetSection("validIssuer").Value,
                    ValidAudience = jwtSettings.GetSection("validAudience").Value,
                    IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(jwtSettings.GetSection("securityKey").Value))
                };
            });
            services.AddSignalR();

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

            // In production, the Angular files will be served from this directory
            services.AddSpaStaticFiles(configuration =>
            {
                configuration.RootPath = "ClientApp/dist";
            });

            // requires using Microsoft.Extensions.Options
            services.Configure<DatabaseSettings>(
                Configuration.GetSection(nameof(DatabaseSettings)));

            services.AddSingleton<IDatabaseSettings>(sp =>
                sp.GetRequiredService<IOptions<DatabaseSettings>>().Value);

            services.AddSingleton<FileService>();

            services.AddSingleton<InternalReportService>();


            services.AddTransient<MailService>();
            services.AddMvc(option => option.EnableEndpointRouting = false);


        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            app.UseRouting();
            app.UseMvc();
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Error");
                app.UseHsts();
            }
            app.UseHttpsRedirection();
            app.UseStaticFiles();          
            app.UseAuthentication();
            app.UseAuthorization();             

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapHub<CoreHub>("/corehub");
                endpoints.MapControllerRoute("default", "{controller=Home}/{action=Index}");

            });

            app.UseSpa(spa =>
            {
                  
                spa.Options.SourcePath = "ClientApp";

                if (env.IsDevelopment())
                {
                    spa.UseProxyToSpaDevelopmentServer("http://localhost:4200");

                }
            });
        }
    }

控制器

[Authorize]
public async Task UploadFile(IFormFile file)
{
// Do Stuff
}

好了，您已经配置了 API 的身份验证部分，现在您需要以相同的方式配置授权......

你可以这样配置：

services.AddAuthorization(options =>
{
    options.AddPolicy("Default", new AuthorizationPolicyBuilder()
        .AddAuthenticationSchemes(JwtBearerDefaults.AuthenticationScheme)
        .RequireAuthenticatedUser()
        .Build());

    options.AddPolicy("Admin", new AuthorizationPolicyBuilder()
        .RequireRole("Admin")
        .AddAuthenticationSchemes(JwtBearerDefaults.AuthenticationScheme)
        .RequireAuthenticatedUser()
        .Build());
});

然后您将能够使用该属性

[Authorize("User")]
[Authorize("Admin")]

在您的控制器或特定端点上。

如果您希望将此默认策略应用于所有端点/控制器并仅控制 if 的“AllowAnonymous”部分，您可以执行以下操作：

services.AddMvc()
        .AddMvcOptions(options =>
        {
            // Mark all endpoints with the default policy
            options.Filters.Add(new AuthorizeFilter("Default"));
        })

根据您的身份验证方案，您应该这样指定属性： [Authorize(AuthenticationSchemes = "Bearer")] 并且这应该按您的预期工作
