 | JSP权限控制源码 偶然翻到很多年前，刚学java的时候学的一段代码。或许，现在让写，还写不出来了。技术如潮、不进则退。还是年轻好啊，思路清晰、精神充沛。 [java] <%@ page contentType="text/html; charset=gb2312" %> <%@ page import="qlsoft.Pwebs.Business.PermitBean" %> <jsp:useBean id="permitBean" scope="session" class="qlsoft.PWebs.Business.PermitBean" /> <%@ page import="qlsoft.PWebs.Business.MemberBean" %> <jsp:useBean id="memberBean" scope="session" class="qlsoft.PWebs.Business.MemberBean" /> <% String action= request.getParameter("action"); %> <script language="javascript"> //alert("Permit request action:" + "<%=action%>"); </script> <% if("login".equalsIgnoreCase(action)) {//会员登录:验证用户身份,并设置Session变量及已登录标志 //获取登录参数 String userName= request.getParameter("username"); String userPwd= request.getParameter("password"); System.out.println("帐号:" + userName + "密码:" + userPwd); if(userName == null || userName == "" || userPwd == null || userPwd == "") {//请求的参数无效 %> <script language="javascript"> alert("没有会员登录必须的请求参数！"); window.history.go(-1); </script> <% } else {//参数有效 if(permitBean.memberLogin(userName,userPwd)) {//登录成功 //chengxiaoxu 2004-05-25 remark code in here to best session.setAttribute("sessionPermit",permitBean); PermitBean ssnPermit = (PermitBean)session.getAttribute("sessionPermit"); String strLogin = ssnPermit.getIsLogin() ? "登录成功！" : "登录失败？？？"; String ackName = ssnPermit.getMgrAckName(); System.out.println("会员帐号:" + strLogin + "\n" + ackName); if(memberBean.getBeanInfoByID(ssnPermit.getMemberID())) { System.out.println("提取会员信息成功！"); session.setAttribute("sessionMember",memberBean); } %> <script language="javascript"> //alert("<%=strLogin %>"); //alert("<%=permitBean.getMsg() %>"); //window.target="_blank"; //此处完成后应该是会员管理中心主页面 window.location="membermain.jsp"; </script> <% } else {//登录失败 %> <script language="javascript"> alert("<%=permitBean.getMsg() %>"); window.history.go(-1); </script> <% }//End of <登录失败> }//End of <参数有效> %> <% }//End of <会员登录> else if("update".equalsIgnoreCase(action)) {//修改会员密码 //获取修改参数 String oldPwd= request.getParameter("oldPassword"); String newPwd= request.getParameter("newPassword1"); if(oldPwd == null || oldPwd == "" || newPwd == null || newPwd == "") {//请求的参数无效 %> <script language="javascript"> alert("没有资料修改必须的请求参数！"); window.history.go(-1); </script> <% }//End of <请求的参数无效> else {//参数有效 %> <% boolean isOK = permitBean.changePassword((String)session.getAttribute("sessionUserAccount"),oldPwd,newPwd); www.atcpu.com %> <script language="javascript">alert("<%=permitBean.getMsg() %>");</script> <% if(isOK) {//修改成功 %> <script language="javascript">window.location="membermain.jsp";</script> <% } else{//修改失败 %> <script language="javascript">window.history.go(-1);</script> <% } }//End of <参数有效> %> <% }//End of <修改会员密码> else if("logout".equalsIgnoreCase(action)) {//会员注销:清空Session变量及已登录标志 //chengxiaoxu 2004-05-25 update code in here to best if(permitBean != null) permitBean.memberLogout(); session.setAttribute("sessionPermit",null); session.setAttribute("sessionMember",null); PermitBean ssnPermit = (PermitBean)session.getAttribute("sessionPermit"); String strLogin = ssnPermit==null ? "注销成功！" : "注销失败？？？"; %> <script language="javascript"> //alert("<%=strLogin %>"); window.location="main.jsp"; </script> <% } else {//错误的页面请求 %> <script language="javascript"> alert("无效的页面请求"); window.history.go(-1); </script> <% }//End of <错误的页面请求> %> | |
