发布到Azure后，Blazor服务器身份验证不起作用

Question

我正在创建Blazor Server应用程序，并使用Identity Server实现了身份验证。 一切正常，直到我将其发布到Azure。一切正常，但登录和注册返回 “对不起，这个地址什么都没有。”

当我单击“登录”时，Azure日志流显示此异常

并注册：

我的启动页面是：

 public void ConfigureServices(IServiceCollection services)
    {

        services.AddTransient<IDisplayMessage, DisplayMessage>();
        services.AddServices();
        services.AddScoped<IAuthenticationStateService, AuthenticationStateServiceServerSide>();

        services.AddAuthentication();

        services.AddDbContextPool<MainDbContext>(options => options
           .UseLoggerFactory(MyLoggerFactory)
           .EnableSensitiveDataLogging()
           .UseMySql(Configuration.GetConnectionString(db), mySqlOptions => mySqlOptions
           .ServerVersion(new Version(8, 0, 19), ServerType.MySql)));

        services.AddDefaultIdentity<ApplicationUser>(options =>
        {
            options.SignIn.RequireConfirmedAccount = false;
            options.Password.RequireLowercase = false;
            options.Password.RequireUppercase = false;
            options.Password.RequireNonAlphanumeric = false;
        })
            .AddSignInManager<ApplicationSignInManager>()
            .AddEntityFrameworkStores<MainDbContext>();

        services.AddRazorPages();
        services.AddServerSideBlazor();
        services.AddScoped<AuthenticationStateProvider, RevalidatingIdentityAuthenticationStateProvider<ApplicationUser>>();

        var assemlies = Assembly.GetExecutingAssembly().GetReferencedAssemblies().Where(a => a.FullName.StartsWith("LaWeb")).Select((item) => Assembly.Load(item)).ToList();
        assemlies.Add(Assembly.GetExecutingAssembly());
        services.AddAutoMapper(assemlies);
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseDatabaseErrorPage();
        }
        else
        {
            app.UseExceptionHandler("/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }
        app.UseHttpsRedirection();
        app.UseStaticFiles();

        app.UseRouting();

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

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
            endpoints.MapBlazorHub();
            endpoints.MapFallbackToPage("/_Host");
        });
    }
}

当从Visual Studio运行或将本地发布到文件夹然后使用cmd运行时，它可以完美运行。
