Fix jqueryify plugin in Firefox, 360 browser cannot upload file problem

Repeated debugging, found that the problem is:jquery uploadify under IE can be uploaded normally, in the implementation of asynchronous upload, each file will be submitted to the server when uploading a request. Each request requires security verification, session and Cookie checksum. Yes, that's it. Since the jquery uploadify is uploaded using Flash, IE automatically bundles the local cookie store to the server each time a data flow request is sent to the background. But Firefox, Chrome won't do it, and they'll think it's not safe. Ha, that's the reason.

Workaround, add these two methods on the Global.asax.cs file:

 protected voidApplication_BeginRequest (Objectsender, EventArgs e) {            Try            {                //solve the problem of Firefox, 360 browser using uploadify upload session missing                stringSession_param_name ="ASPSessionID"; stringSession_cookie_name ="Asp.net_sessionid"; if(Request[session_param_name]! =NULL) {Updatecookie (Session_cookie_name, Request[session_param_name]); }                stringAuth_param_name ="AUTHID"; stringAuth_cookie_name =Formsauthentication.formscookiename; if(Request[auth_param_name]! =NULL) {Updatecookie (Auth_cookie_name, Request[auth_param_name]); }            }            Catch { }        }        Private voidUpdatecookie (stringCookie_name,stringcookie_value) {HttpCookie Cookie=Request.Cookies.Get (cookie_name); if(Cookie = =NULL) {Cookie=NewHttpCookie (cookie_name); } cookie. Value=Cookie_value;        Request.Cookies.Set (cookie); }

Page script, the first Session,cookie information that the current user logged in is sent to the server to verify:

varFormData ={attachmentguid:attachmentguid, ASPSessionID:'@Session. SessionID', AUTHID:'@ (Request.cookies[formsauthentication.formscookiename] = = null? string. Empty:request.cookies[formsauthentication.formscookiename]. Value)'                }; $('#uploadify'). uploadify ({'FormData': FormData,//other parameters sent to the background are specified by Formdata                    'Uploader':'/syscommon/attachmentupload',//pages processed in the background                    'Auto':false,//automatically upload after selecting a file                    'removecompleted':false,//progress bar                    'filetypeexts':'*.gif, *.jpg, *.png',//allow file suffixes to be uploaded                    'Uploadlimit':1,//number of files allowed to upload                    'SizeLimit':3072000,//allow file size to be uploaded                    'SWF':'/scripts/uploadify/uploadify3.2.1/uploadify.swf',//Specify SWF file                    'ButtonText':'Select File',//the text that the button displays                    'Buttonclass':'Uploadify-button',//the style of the button display                    'Multi':true,//set to True to allow multiple file uploads                    'Filetypedesc':'Uploading Files',//text displayed in the File Type drop-down menu at the bottom of the Browse window                    'Queueid':'Filequeue',//upload File page, the ID of the element you want to use as the file queue, default to False auto-generated, without #                    'OnComplete': Function (Event, Queueid, fileobj, response, data) {                        //triggered when a single file upload is completeConsole.log ("msg: Single file upload.

Console.log ('msg: triggered when the current browser does not support Flash'); },                    'Onswfready': Function () {//triggered when the Flash file is loaded successfully. Console.log ('Msg:flash file loaded successfully'); }                })

The problem is solved by this way.

{
