3.后台设置全局变量并查询用户信息
public function UserInfo($user_id){
//查询系统信息$system=array('CmdId'=>'System','Token'=>'wap','PostDetails'=>json_encode(array()));
//通过curl的post方式发送接口请求$curl=new CurlController();
$strs=$curl->SendCurl($system);
$GLOBALS['system']=$strs['AcctDetails'];
if(empty($user_id)){
return false;
}
setcookie("login_uid", $user_id, time() + 3600, "/", C('cookie_url'));
setcookie("rdun", $this->authcode($user_id . "," . time(), "ENCODE"), time() + 3600,"/",C('cookie_url'));
;
$data=array('CmdId'=>'Individual','Token'=>session('token'),'PostDetails'=>json_encode(array('user_id'=>$user_id,)));
//通过curl的post方式发送接口请求$curl=new CurlController();
$str=$curl->SendCurl($data);
$GLOBALS['userinfo']=$str['AcctDetails'];
$newtoken=unserialize($str['AcctDetails']['token']);
$oldtoken=unserialize(session('token'));
if(!empty(session('token')) && !empty($str['AcctDetails']['token'])){
//用户不对if($newtoken['user_id'] !== $newtoken['user_id']){
session('token',null);
session('user_id',null);
header('Location:/Login/Login');
return false;
}
//token不对if($newtoken['time'] !== $oldtoken['time']){
session('token',null);
session('user_id',null);
header('Location:/Login/Login');
return false;
}
//超时的不能在这做,原因是存入session的值不变,如果用户一直操作的话,而且只登陆一次,那么就会出现问题}
return true;
}
