JWT Token MVC Core的自定义statusText

Question

我使用以下文章在我的MVC核心应用程序中实现了JWT令牌认证：

Link 1

Link 2

这就是我Startup.cs

中的内容

    private const string SecretKey = "MySecretKey"; //TODO: remove hard coded get from environments as suggested in Blog
    private readonly SymmetricSecurityKey _signingKey = new SymmetricSecurityKey(Encoding.ASCII.GetBytes(SecretKey));


    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {


        var jwtAppSettingOptions = Configuration.GetSection(nameof(JwtIssuerOptions));
        var tokenValidationParameters = new TokenValidationParameters
        {
            ValidateIssuer = true,
            ValidIssuer = jwtAppSettingOptions[nameof(JwtIssuerOptions.Issuer)],

            ValidateAudience = true,
            ValidAudience = jwtAppSettingOptions[nameof(JwtIssuerOptions.Audience)],

            ValidateIssuerSigningKey = true,
            IssuerSigningKey = _signingKey,

            RequireExpirationTime = true,
            ValidateLifetime = true,


            ClockSkew = TimeSpan.Zero
        };

        app.UseJwtBearerAuthentication(new JwtBearerOptions
        {
            AutomaticAuthenticate = true,
            AutomaticChallenge = true,
            TokenValidationParameters = tokenValidationParameters,

        });

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseBrowserLink();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        app.UseStaticFiles();

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");


            routes.MapRoute(
                    name: "areaRoute",
                    template: "{area:exists}/{controller}/{action}",
                    defaults: new { controller = "Home", action = "Index" }
                    );
        });

    }



    public void ConfigureServices(IServiceCollection services)
    {
        // Add framework services.
        services.AddMvc(options => { });

        services.Configure<MvcOptions>(options => { });
        services.Configure<IISOptions>(options => { });

        services.AddOptions();


        #region Authentication and Authorisation

        services.AddAuthorization(options =>
        {
            using (var dbContext = new FoodHouseContext(Configuration.GetConnectionString("DefaultConnection")))
            {
                var features = dbContext.Features.Select(s => s.Name).ToList();
                foreach (var feature in features)
                {
                    options.AddPolicy(feature, policy => policy.Requirements.Add(new FeatureRequirement(feature)));
                }
            }
        });

        // Configure JWT Token Settings
        var jwtAppSettingOptions = Configuration.GetSection(nameof(JwtIssuerOptions));

        services.Configure<JwtIssuerOptions>(options =>
        {
            options.Issuer = jwtAppSettingOptions[nameof(JwtIssuerOptions.Issuer)];
            options.Audience = jwtAppSettingOptions[nameof(JwtIssuerOptions.Audience)];
            options.SigningCredentials = new SigningCredentials(_signingKey, SecurityAlgorithms.HmacSha256);
        });

        #endregion


    }

一切正常 - 令牌已经发布且Authorize工作正常，当我发出未经身份验证的请求时，我得到以下回复：

正如您所见Status = 401，这意味着UnAuthenticated - 但正如您所见，StatusText为空。

现在有很多原因可以解决为什么请求可能是UnAuthenticated，例如JWT Token expired，我想要做的是根据服务器上的验证规则失败传递自定义状态文本，我该如何在MVC Core中执行此操作？
