使用 Kendo 将 ASP.Net MVC 异步文件上传到 API 失败

Question

所以当我将文件发送到 MVC 控制器时，这个 Kendo UI Upload 运行良好，但我必须更改它并将文件直接发送到 API 控制器，但它失败了。

这是剑道上传初始化代码：

$("#files").kendoUpload({
  async: {
    saveUrl: "@WebApiHelper.GetUrl("Notification/UploadFile")",
    removeUrl: "remove",
    autoUpload: true
  },
  success: function(),
  error: function()
}

在 Chrome 控制台上，它会在“网络”选项卡中请求的状态文本中显示 Load Canceled：

请求的结果如下图：

Request URL:http://localhost:45706/api/Notification/UploadFile
Request Method:OPTIONS
Status Code:200 Ok

请注意，状态码是 200，因为我在方法中返回了它。于是就到达了API方法……

[HttpPost][HttpOptions]
public HttpResponseMessage UploadFile(HttpPostedFileBase files)

...但是files 参数与null 不同。

这是 API webconfig 文件中与 CORS 相关的属性：

<httpProtocol>   
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="allow-access-from domain" value="*" />
    <add name="Access-Control-Allow-Headers" value="origin, accept, content-type" />
    <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
    <add name="Access-Control-Allow-Credentials" value="true" />  
  </customHeaders> 
</httpProtocol>

有什么想法吗？任何帮助将不胜感激！

这段代码对我有用。

public ActionResult Document_Create([DataSourceRequest] DataSourceRequest request, Customer obj, IEnumerable<HttpPostedFileBase> Docs)
        {
                    foreach (var Doc in Docs)
                    {
                        string newFileName = Path.GetFileName(Doc.FileName).Replace(" ",""); //Guid.NewGuid().ToString() + Path.GetExtension(Doc.FileName);
                        var physicalPath = Path.Combine(Server.MapPath("~/Documents/"), newFileName);
                        Doc.SaveAs(physicalPath);

                    }
            return Json(new[] { obj }.ToDataSourceResult(request, ModelState));
        }
