asp.net-core - app.UseExceptionHandler ("Home/Error") 不去主页/错误

Question

我创建了一个简单的主页/错误页面，我可以毫无问题地直接访问它。它现在只返回一些静态 HTML。当我将 Startup.cs 更改为:

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        loggerFactory.AddConsole(Configuration.GetSection("Logging"));
        loggerFactory.AddDebug();

        if (env.IsDevelopment())
        {

            app.UseBrowserLink();
            //app.UseDeveloperExceptionPage();
            app.UseExceptionHandler("/Home/Error");

        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        app.UseIISPlatformHandler();
        app.UseSession();
        app.UseStaticFiles();

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

我希望被重定向到 Home/Error。相反，我得到一个空白屏幕，如果我查看 Chrome 开发人员工具中的“网络”选项卡，我会看到从我的“Home/TestException”操作返回 500 Status，这引发了异常。

如果我将其切换到 app.UseDeveloperExceptionPage()，该页面就会正常显示。知道为什么这不起作用吗？

我正在使用 .Net Core 1.0.0-rc1-update1。

app.UseStatusCodePagesWithReExecute 似乎运行良好:

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