Yii获取系统级请求参数的方法

Posted 2020-06-14

一、GET/POST

1、获取GET/POST过来的数据

Yii::app()->request->getParam(‘id‘);

2、判断数据提交方式

Yii::app()->request->isPostRequest;

二、session/cookie

1、session常用操作

$_SESSION等价于Yii::app()->session;

1.1、写入session

//启动session
$session = new ChttpSession;
$session->open();
Yii::app()->session[‘key‘] = ‘value‘;

1.2、读取session

Yii::app()->session[‘key‘];

1.3、获取session的ID

Yii::app()->session->sessionID

1.4、销毁session

//移除所有的session变量
Yii::app()->session->clear();
//移除存储在服务器端的数据
Yii::app()->session->destroy();

2、cookie

2.1、设置cookie

$cookie = new CHttpCookie(‘mycookie‘, ‘this is my cookie‘);
$cookie->expire = time() + 60*60*24*30;
Yii::app()->request->cookie[‘mycookie‘] = $cookie;

2.2、读取cookie

$cookie = Yii::app()->request->getCookies();
echo $cookie[‘mycookie‘]->values;

2.3、销毁cookie

$cookie = Yii::app()->request->getCookies();
unset($cookie[$name]);
