class TestAction extends Action{
// function _before_index(){
// if(!isset($_SESSION['username']) || $_SESSION['username']=='')
// {
// $this->redirect('Index/index');
// }
// } public function index(){
$this->display();
}
}; 此时跳过登录检查,那么怎么判断登录呢？ //********************************* 前置和后置操作上一页下一页系统会检测当前操作是否具有前置和后置操作，如果存在就会按照顺序执行，前置和后置操作的方法名是在要执行的方法前面加 _before_和_after_，例如：
class CityAction extends Action{
//前置操作方法
public function _before_index(){
echo 'before<br/>';
}
public function index(){
echo 'index<br/>';
}
//后置操作方法
public function _after_index(){
echo 'after<br/>';
}
}
如果我们访问
http://serverName/index.php/City/index
结果会输出 before
index
after <?php
class TestAction extends Action{
function _before_index(){
if(!isset($_SESSION['username']) || $_SESSION['username']=='')
{
$this->redirect('Index/index');
}
} public function index(){
$this->display();
}
}; 此时会跳转到登录页 /*********** 打印信息: <?php
class TestAction extends Action{
function _before_index(){
var_dump($_SESSION);
#echo $_SESSION;
if(!isset($_SESSION['username']) || $_SESSION['username']=='')
{
#$this->redirect('Index/index');
}
} public function index(){
$this->display();
}
}; 此时访问http://localhost/DEVOPS/index.php/Test/index: array (size=1)
'verify' => string '8289889263db4a40463e3f358bb7c7a1' (length=32) test 20160707 scan! 可以看到 $_SESSION['username'] 为空 如果登录的话SESSION里的信息为: array (size=3)
'verify' => string '198dd5fb9c43b2d29a548f8c77e85cf9' (length=32)
'username' => string 'admin' (length=5)
