异步控制器返回＆QUOT; System.Threading.Tasks.Task`1 [System.Web.Mvc.ActionResult] QUOT; [英] Async Controller Returning "System.Threading.Tasks.Task`1[System.Web.Mvc.ActionResult]"

问题描述

我试图找出为什么一把umbraco 7.2.4似乎并不在我的ASP.NET MVC控制器来处理异步任务。我觉得像我读过几乎每一个可能的堆栈溢出，并一把umbraco Q＆放大器;一个，并试图尽可能多的方法来尽量缩小问题。这是既为一把umbraco 7和; MVC 4和放大器; MVC 5.工作得很好，在MVC项目，而不一把umbraco。

HomeController.cs：

 使用System.Threading.Tasks;
使用System.Web.Mvc;
使用Umbraco.Web.Models;
使用Umbraco.Web.Mvc;命名空间Umbraco.Async.Website.Controllers
{
    公共类HomeController的：RenderMvcController
    {
        公开新异步任务＆LT;＆的ActionResult GT;指数（RenderModel模型）
        {
            VAR menuModel =新HomeViewModel（模型）;
            等待Task.Delay（1000）;
            返回视图（家，menuModel）;
        }
    }    公共类HomeViewModel：RenderModel
    {
        公共字符串测试=比萨是真棒!!!!;        公共HomeViewModel（RenderModel模型）
            ：基地（model.Content，model.CurrentCulture）
        {        }
    }
}
 

Home.cshtml：

  @ * @继承Umbraco.Web.Mvc.UmbracoTemplatePage * @
@inherits UmbracoViewPage＆LT; Umbraco.Async.Website.Controllers.HomeViewModel＆GT;
@ {
    布局= NULL;
}＆LT; H1＆GT; @ Model.Test＆LT; / H1＆GT;
 

在结束浏览器不显示渲染视图，只是文本字符串：

  

System.Threading.Tasks.Task`1 [System.Web.Mvc.ActionResult]

解决方案

我已经提出了与一把umbraco一个问题，对于这​​个问题，因为我已经奔这个苦苦挣扎了好一阵。我已经写放在这里但简而言之，你可以使用它代替：

 公共异步任务＆LT;＆的ActionResult GT;首页（RenderModel模型）
{
    VAR menuModel =新HomeViewModel（模型）;
    等待Task.Delay（1000）;
    返回视图（家，menuModel）;
}
 

的区别是，首页行动需要precedence过失败的指标作用，因为它是从模板名称不是文档类型别名路由。

I'm trying to work out why Umbraco 7.2.4 just doesn't seem to handle asynchronous tasks in my ASP.NET MVC controller. I feel like I've read almost every possible stack overflow and umbraco q&a, and tried many possible methods to try narrow down the problem. This is both for Umbraco 7 & MVC 4 and & MVC 5. It works just fine in an MVC project without Umbraco.

HomeController.cs:

using System.Threading.Tasks;
using System.Web.Mvc;
using Umbraco.Web.Models;
using Umbraco.Web.Mvc;

namespace Umbraco.Async.Website.Controllers
{
    public class HomeController : RenderMvcController
    {
        public new async Task<ActionResult> Index(RenderModel model)
        {
            var menuModel = new HomeViewModel(model);
            await Task.Delay(1000);
            return View("Home", menuModel);
        }
    }

    public class HomeViewModel : RenderModel
    {
        public string Test = "Pizza is awesome!!!!";

        public HomeViewModel(RenderModel model)
            : base(model.Content, model.CurrentCulture)
        {

        }
    }
}

Home.cshtml:

@*@inherits Umbraco.Web.Mvc.UmbracoTemplatePage*@
@inherits UmbracoViewPage<Umbraco.Async.Website.Controllers.HomeViewModel>
@{
    Layout = null;
}

<h1>@Model.Test</h1>

In the end the browser shows no rendered view, and just the text string:

System.Threading.Tasks.Task`1[System.Web.Mvc.ActionResult]

解决方案

I've raised an issue with Umbraco for this issue as I have ben struggling with this for quite a while. I have written an article on a solution here but in a nutshell you can use this instead:

public async Task<ActionResult> Home(RenderModel model)
{
    var menuModel = new HomeViewModel(model);
    await Task.Delay(1000);
    return View("Home", menuModel);
}

The difference being that the Home action takes precedence over the failing Index action as it is routed from the template name not the document type alias.
