Thinkphp检测登录或操作超时(针对设置session有效期失效)

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">步骤如下：</span>

1.登录函数中存登录时间：

session("logintime",time());

2.在APP/Index/Common/common.php添加公共类：

class CheckAction extends Action {
        public function __construct() {
            parent::__construct();
            $this->checkAdminSession();
        }
        public function checkAdminSession() {
           // echo "happy";
            //设置超时为10分
            $nowtime = time();
            $s_time = session("logintime");
            if (($nowtime - $s_time) > 1800) {
                session("logintime",null);
                $this->error("当前用户未登录或登录超时，请重新登录", U("Admin/Index/index"));
            } else {
                session("logintime",$nowtime);
            }
        }
}

3.APP的每个需要检测的Action都继承上面的类：

例：

lass AnnouceAction extends CheckAction
{
   
    public function lists(){
		$username = session("agentName");
		//判断是否有输入密码；
		if(empty($username)){
		//如果为空跳回登录页；
			$this->redirect("QiXunAgent/Index/index");
		}
		$age=M("agentuser")->where(array("account"=>$username))->find();
		$m=M("announceforman");			 		
	 //加载分页类
		import("ORG.Util.Page");
	//计算记录总数
		$condition["managerID"] = 0;
		$condition["agentID"] = $age["id"];
		$count = $m->where($condition)->count();
	//实例化分页类
		$page = new Page($count,8);
	//设置主题
		$page->setConfig("header","");
		$page->setConfig("theme","%totalRow% %header% 当前第 %nowPage% 页  共 %totalPage% 页 %upPage% %downPage% %first% %prePage% <span style="letter-spacing:5px">%linkPage%</span> %nextPage% %end%");

	//设置超链接
		$this->show = $page->show();
			
		$data = $m->where($condition)->order("datetime desc")->limit($page->firstRow.",".$page->listRows)->select();	
		$this->assign("data",$data);
		$this->display();
	}
}
