Question

我创建了一个MVC项目，按钮点击它可以将页面内容保存为.xlsx文件。这适用于Chrome / FF，但不适用于IE 9及更低版本。

为了处理这种边缘情况，我实现了一个HTTP处理程序。奇怪的是在调试时（VS 2013）＆＃34;没有断点＆＃34;代码工作正常，我可以在IE中下载excel文件。但是当我没有进行调试并且只是浏览页面时，我得到了一个404：请求的URL：/Home/ExportHandler.axd 我想知道为什么我会得到404，为什么我的路线选择到put / Home在url中，有没有办法删除它？这里的任何方式都是代码：

HTTP HANDLER

    namespace MvcApplication2
{
    public class ExportHandler : IHttpHandler
    {
        public void ProcessRequest(HttpContext context)
        {
            if (context.Request.Form["contentType"] != null &&
               context.Request.Form["fileName"] != null &&
               context.Request.Form["data"] != null)
            {
                context.Response.Clear();
                context.Response.ContentType = context.Request.Form["contentType"].ToString();
                context.Response.Charset = "UTF-8";
                context.Response.Expires = 0;
                context.Response.AppendHeader("Content-transfer-encoding", "binary");
                context.Response.AppendHeader("Content-Disposition",
                                              "attachment; filename=" + context.Request.Form["fileName"].ToString());
                context.Response.BinaryWrite(Convert.FromBase64String(context.Request.Form["data"].ToString()));
                context.Response.Flush();
                context.Response.End();
            }
        }
        public bool IsReusable
        {
            get { return false; }
        }
    }
}

MVC ROUTE

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

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