app.UseExceptionHandler（“ Home / Error”）不会转到Home / Error

Question

我创建了一个简单的“主页/错误”页面，可以毫无问题地直接转到该页面。它现在只返回一些静态HTML。当我将Startup.cs更改为此时：

    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?}");
        });
    }

我希望将重定向到Home / Error。取而代之的是，我得到了一个空白屏幕，如果我查看Chrome Developer工具中的“网络”标签，则会看到我的“ Home / TestException”操作返回500状态，并抛出异常。

如果我将其切换到app.UseDeveloperExceptionPage（），则显示该页面就很好。任何想法为什么这不起作用？

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");
 }
