前段時間在作項目的時候用到了JQuery的一個上傳插件,可是呢,在火狐下面上傳的時候在後臺怎麼也獲取不到一些信息,後來才發現原來是session丟失了,個人解決方案很簡單,直接是把要獲取的信息加到上傳的url後面,而後再從後來截取出來,這樣就不會丟失了javascript
這些信息是要傳遞到後臺處理的有用信息,可是session丟失了,用戶信息後臺獲取不到,經過加載url後面,具體代碼以下:css

String userOrg = request.getSession().getAttribute("userOrg").toString();
String videoInfo = videoinfo + "~" + userName + "~" + userOrg;//要傳遞到後臺的信息
