Asp.net mvc 4 行动需要两次

总之，我遇到了一个问题，MVC操作被调用了两次。请帮忙复习一下

视图代码很简单

<div class="divContainer">
    <ul>
        @foreach (var blobName in ViewBag.BlobList)
        {
            <li>@Html.ActionLink("Delete", "Delete", "LogBlob", new { blobUrl = blobName }, null)</li>
        }
    </ul>
</div>


public class LogBlobController : Controller
{
    public ActionResult Delete(string blobUrl)
    {
       //...
       //The action is call twice.
    }
}

MVC的

RouteConfig

的默认实现如下所示

public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Login", action = "Login", id = UrlParameter.Optional }
            );
        }

页面中的Html如下所示

public class LogAreaRegistration : AreaRegistration 
    {
        public override string AreaName 
        {
            get 
            {
                return "Log";
            }
        }

        public override void RegisterArea(AreaRegistrationContext context) 
        {
            context.MapRoute(
                "Log_default",
                "Log/{controller}/{action}/{id}",
                new { action = "Index", id = UrlParameter.Optional }
            );
        }
    }

<a href="/Log/LogBlob/Delete?blobUrl=%2Fserverlogcontainer%2F1a33f37c-4b21-41aa-9f48-0b5f6b86577f.zip">Delete</a>

我两次怀疑原因是它们（

LogAreaRegistration

和

RouteConfig

）同时工作。谢谢。

不，我没有在链接上添加任何dom事件，如单击

之类。你仍然不知道。。。下载如果您还没有，请监视Http请求以查看是否有2个对该操作的调用。还可以尝试显式注册路由，或在操作中使用
[route]
属性。此选项有助于解决您的问题：
