3.2版uploadify详细例子（含FF和IE SESSION问题）

在使用uploadfiy3.2版本时需要下载jquery.tmpl.min.js并引用在Jquery下面

$("#uploadify").uploadify({

                'uploader': '/LZKS/Handler/BigFileUpLoadHandler.ashx',

                'swf': '/LZKS/Scripts/uploadify/uploadify.swf',

                'cancelImage': '/LZKS/Scripts/uploadify/cancel.png',

                'queueID': 'fileQueue',

                //'auto': false,

                'multi': true,

                'buttonText': '文件上传',

                'formData': { 'ASPSESSID': ASPSESSID, 'AUTHID': auth },

                'onSelect': function (file) {

                    $('#uploadify').uploadifySettings('formData', { 'ASPSESSID': ASPSESSID, 'AUTHID': auth });

                    alert(formDate);

                },

                'onComplete': function (file, data, response) {

                },



                'onQueueComplete': function () {

                    alert("上传完成！");

                    $('#fileQueue').attr('style', 'visibility :hidden');

                },

                'onSelectError': function (file, errorCode, errorMsg) {

                    $('#fileQueue').attr('style', 'visibility :hidden');

                },

                'onUploadStart': function (file) {

                    $('#fileQueue').attr('style', 'top:200px;left:400px;width:400px;height :400px;visibility :visible');

                }

            });

        });

用uplodify上传还有一个小问题就是在FF下session将会出现丢失的情况 ，在Gobal中加入如下代码来将上传过程中定义的session传至服务器上

protected void Application_BeginRequest(object sender, EventArgs e)

        {

            /* we guess at this point session is not already retrieved by application so we recreate cookie with the session id... */

            try

            {

                string session_param_name = "ASPSESSID";

                string session_cookie_name = "ASP.NET_SessionId";



                if (HttpContext.Current.Request.Form[session_param_name] != null)

                {

                    UpdateCookie(session_cookie_name, HttpContext.Current.Request.Form[session_param_name]);

                }

                else if (HttpContext.Current.Request.QueryString[session_param_name] != null)

                {

                    UpdateCookie(session_cookie_name, HttpContext.Current.Request.QueryString[session_param_name]);

                }

            }

            catch

            {

            }



            try

            {

                string auth_param_name = "AUTHID";

                string auth_cookie_name = FormsAuthentication.FormsCookieName;



                if (HttpContext.Current.Request.Form[auth_param_name] != null)

                {

                    UpdateCookie(auth_cookie_name, HttpContext.Current.Request.Form[auth_param_name]);

                }

                else if (HttpContext.Current.Request.QueryString[auth_param_name] != null)

                {

                    UpdateCookie(auth_cookie_name, HttpContext.Current.Request.QueryString[auth_param_name]);

                }



            }

            catch

            {

            }

        }



        private void UpdateCookie(string cookie_name, string cookie_value)

        {

            HttpCookie cookie = HttpContext.Current.Request.Cookies.Get(cookie_name);

            if (null == cookie)

            {

                cookie = new HttpCookie(cookie_name);

            }

            cookie.Value = cookie_value;

            HttpContext.Current.Request.Cookies.Set(cookie);

        }

在JS加载前面定义下面两个变量

 var auth = "<% = Request.Cookies[FormsAuthentication.FormsCookieName]==null ? string.Empty : Request.Cookies[FormsAuthentication.FormsCookieName].Value %>";

 var ASPSESSID = "<%= Session.SessionID %>";

　　

Handler文件代码如下：

  public class BigFileUpLoadHandler : IHttpHandler, IRequiresSessionState

    {

        DALFile Fdal = new DALFile();

        public void ProcessRequest(HttpContext context)

        {

            context.Response.ContentType = "text/plain";

            VideoUpLoad(context, CLSOFT.Web.LZKS.Edu.Globe.filename);

        }

        public void VideoUpLoad(HttpContext context, string fileFolderName)

        {

            context.Response.Charset = "utf-8";

            string aaaaaaa=context.Request.QueryString["sessionid"];

            HttpPostedFile file = context.Request.Files["Filedata"];

            string uploadPath = HttpContext.Current.Server.MapPath(UploadFileCommon.CreateDir(fileFolderName));

            if (file != null)

            {

                if (!Directory.Exists(uploadPath))

                {

                    Directory.CreateDirectory(uploadPath);

                }

                Model.ModelFile model = new Model.ModelFile();

                model.File_ID = Guid.NewGuid().ToString();

                model.File_Name = file.FileName;

                model.File_Path = UploadFileCommon.CreateDir(fileFolderName);

                model.File_Size = file.ContentLength;

                model.File_Extension = file.FileName.Substring(file.FileName.LastIndexOf('.') + 1);

                model.File_Date = DateTime.Now;

                model.File_CurrentMan = CLSOFT.Web.LZKS.Edu.Globe.name;

                file.SaveAs(uploadPath + model.File_Name);

            

                List<Model.ModelFile> list = null;

                if (context.Session["File"] == null)

                {

                    list = new List<Model.ModelFile>();

                }

                else

                {

                    list = context.Session["File"] as List<Model.ModelFile>;

                }

                list.Add(model);

                context.Session.Add("File", list);

            }

            else

            {

                context.Response.Write("0");

            } 

        }

//这段代码的功能是将多文件的信息存到context.Session["File"] as List<Model.ModelFileModel.ModelFile>为文件信息类 

//实现批量上传的信息给Session
