C# 基础设施IgniteUI IGFileUpload不'；t在ASP.NET MVC CORE 3.0中将文件上载到服务器

假设我有一个简单的

Index.cshtml

视图：

<link href="~/libs/infragistics/css/themes/infragistics/infragistics.theme.css" rel="stylesheet" />

问题是，正如您所看到的，当控件工作时，文件实际上并没有上载到服务器。我不认为这是一个bug，我认为我对

CORE 3.0

不够熟悉，并且在

IGUploadStatusHandler.ashx

的配置中缺少了一些非常明显的东西
如果可能的话，我宁愿避免挖掘默认的Web处理程序代码

@using Infragistics.Web.Mvc
@using Microsoft.AspNetCore.Http
@{
    ViewData["Title"] = "Index";
}

<div id="igFileUpload"></div>

<script src="~/libs/JQuery/jquery.js"></script>
<script src="~/libs/JQueryUI/jquery-ui.js"></script>
<script src="~/libs/infragistics/js/infragistics.core.js"></script>
<script src="~/libs/infragistics/js/infragistics.lob.js"></script>

@(
    Html.Infragistics().Upload()
        .ID("igFileUpload")
        .Mode(UploadMode.Multiple)
        .AutoStartUpload(true)
        .ProgressUrl(Url.Content("~/IGUploadStatusHandler.ashx"))
        .UploadUrl(Url.Content("~/ig_fua34sf345sdf13sdf3454erdsf2345asd3425df5235d54df345.aspx"))
        .ControlId("serverID1")
        .Width("600px")
        .Render()
)

<div id="error-message" style="color: #FF0000; font-weight: bold;"></div>

<script type="text/javascript">
    $(function () {
        $("#igFileUpload").bind({ iguploadonerror: function (e, args) {
                $("#error-message").html(args.errorMessage).stop(true, true).fadeIn(500).delay(3000).fadeOut(500);
            }

根据@MasLoo的建议，我实现了中间件以替换显然需要的

IgnoreRoute

，但我无法理解直接从中抛出404将如何使处理程序工作：

(...)
app.UseMiddleware<IgnoreRouteMiddleware>();
(...)

@using Infragistics.Web.Mvc
@using Microsoft.AspNetCore.Http
@{
    ViewData["Title"] = "Index";
}

<div id="igFileUpload"></div>

<script src="~/libs/JQuery/jquery.js"></script>
<script src="~/libs/JQueryUI/jquery-ui.js"></script>
<script src="~/libs/infragistics/js/infragistics.core.js"></script>
<script src="~/libs/infragistics/js/infragistics.lob.js"></script>

@(
    Html.Infragistics().Upload()
        .ID("igFileUpload")
        .Mode(UploadMode.Multiple)
        .AutoStartUpload(true)
        .ProgressUrl(Url.Content("~/IGUploadStatusHandler.ashx"))
        .UploadUrl(Url.Content("~/ig_fua34sf345sdf13sdf3454erdsf2345asd3425df5235d54df345.aspx"))
        .ControlId("serverID1")
        .Width("600px")
        .Render()
)

<div id="error-message" style="color: #FF0000; font-weight: bold;"></div>

<script type="text/javascript">
    $(function () {
        $("#igFileUpload").bind({ iguploadonerror: function (e, args) {
                $("#error-message").html(args.errorMessage).stop(true, true).fadeIn(500).delay(3000).fadeOut(500);
            }
        });
    });
</script>

我想我快到了，但还不完全到。我注意到，出于某种原因，如果我保留默认URL，if代码将在UploadUrl中查找文件文件夹，而不是查找ig_fua34sf345sdf13sdf3454erdsf2345asd3425df5235d54df345.aspx路径，因此我将HtmlHelper更改为：

Html.Infragistics().Upload()
    .ID("igFileUpload")
    .Mode(UploadMode.Multiple)
    .AutoStartUpload(true)
    .ProgressUrl(Context.GetAbsoluteUrl("~/IGUploadStatusHandler.ashx"))
    .UploadUrl(Context.GetAbsoluteUrl("~/ig_fua34sf345sdf13sdf3454erdsf2345asd3425df5235d54df345.aspx"))

基于MVC项目，您需要忽略到HTTP处理程序的路由。IgnoreRoute在ASP.NET CORE 3.0 afaik中不可用。对，它在整个.NET CORE中都不可用（在CORE 1.0中也不可用）。您可以将其作为中间件来实现。更新我的帖子以包含您的建议@MasLoo，我将感谢您的进一步帮助。这行有什么问题：
options.FileUploadPath=$@“{Directory.GetCurrentDirectory（）}\Data”
？它也容易出错吗？
