即使文件上传,Kendo UI Upload似乎也没有返回onSuccess。下面是我在C#页面加载时使用的代码。我需要提交要返回的文件名
我在这里做错了什么?
public string ProcessRequest()
{
Response.Expires = -1;
try
{
HttpPostedFile postedFile = Request.Files["files"];
string savepath = Server.MapPath(System.Configuration.ConfigurationManager.AppSettings["ExcelImport"]);
string filename = CL.GenerateUniqueName(postedFile.FileName, Session["LoginUserID"].ToString()); \\ <== generate a unique file name and return it to upload
if (!Directory.Exists(savepath))
Directory.CreateDirectory(savepath);
string strCompath = Path.Combine(savepath, filename);
postedFile.SaveAs(strCompath);
Response.ContentType = "text/plain";
string json = JsonConvert.SerializeObject(filename, Formatting.Indented); //<== tried to convert to json but still does not work
return "";
}
catch (Exception ex)
{
Response.Write(ex.ToString());
return ex.ToString();
}
}
成功代码的Javascript
function onSuccess(e) {
console.log("Success (" + e.operation + ") :: " + getFileInfo(e));
}
修改1
我发现整个html似乎在上传后呈现。我如何只返回uniquefilename?
更新
我为解决此问题所做的是调用另一个没有html的aspx文件,并得到正确的响应。不确定这是否是正确的方法,但对我有用。现在只需要了解如何获取唯一的文件名。
我的代码:
$("#files").kendoUpload({
async: {
saveUrl: "Response.aspx", //<== earlier this was pointing to the current aspx where the control is
removeUrl: "remove",
autoUpload: true
},
showFileList: true,
success: onSuccess,
remove: onRemove,
upload: onUpload,
complete: onComplete,
error: onerror
});
服务器代码:
protected void Page_Load(object sender, EventArgs e)
{
Response.Expires = -1;
try
{
HttpPostedFile postedFile = Request.Files["files"];
string savepath = Server.MapPath(System.Configuration.ConfigurationManager.AppSettings["ExcelImport"]);
string filename = CL.GenerateUniqueName(postedFile.FileName, Session["LoginUserID"].ToString());
if (!Directory.Exists(savepath))
Directory.CreateDirectory(savepath);
string strCompath = Path.Combine(savepath, filename);
postedFile.SaveAs(strCompath);
Context.Response.Clear();
Context.Response.ContentType = "text/plain";
Context.Response.Write("{}");
}
catch (Exception ex)
{
Response.Write(ex.ToString());
// return ex.ToString();
}
}
答案 0 :(得分:1)
供将来参考,
您应该使用WebService(ASMX)文件来处理和返回您的JSON。请记住,只会使用返回的http 200状态代码调用javascript成功块。
如果您使用MVC框架,只需返回JSON结果类型即可。
如果您想保留aspx hack,可以调用以下内容删除HTML
response.clear();
response.write(yourJSON);
response.end();
但我再次不鼓励这样做,并推荐专门的服务。
