html - Kendo UI 上传小部件 - saveField 和 saveUrl

Question

使用Kendo UI upload widget，如何在wcf服务操作中获取上传的文件。使用我的 wcf 方法提供了 saveUrl 选项，但不确定如何获取上传文件的详细信息。仍然无法理解 saveField 选项的用途。请建议。

////服务声明 公共(public)接口(interface) ISampleWcf { [操作合约] [WebGet(BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)] void DoWork();

        [OperationContract]
        [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
        void SaveAttachments(List<HttpPostedFileBase> files);
    }

////服务实现。

public class SampleWcf : ISampleWcf
    {
        public void DoWork()
        {
        }

        public void SaveAttachments(List<HttpPostedFileBase> files)
        {
            //HttpPostedFile file;
            var current = System.Web.HttpContext.Current;
            if(current != null)
            {
                var f = current.Request["files"];
            }
        }
    }

////Jquery脚本

$("#files").kendoUpload({
                     async: {
                         saveUrl: "SampleWcf.svc/SaveAttachments",
                         saveField: "customSaveField",
                         autoUpload: true
                     },
                     success: onSuccess,
                     error: onError
                 });

                 function onSuccess(e) {
                     alert('s');
                 }

                 function onError(e) {
                     // Array with information about the uploaded files
                     var files = e.files;

                     if (e.operation == "upload") {
                         alert("Failed to upload " + files.length + " files");
                     }
                 }

Answer 1

“Async saveField”的值为“customSaveField”。然后它应该与您的 SaveAttachments 的参数名称相匹配。

public void SaveAttachments(List<HttpPostedFileBase> customSaveField)
