YII 获取系统级请求参数的常用方法(转）

1、GET/POST

1.1、获取GET/POST过来的数据

Yii::app()->request->getParam( 'id' );

1.2、判断数据提交方式

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

2、session/cookie

2.1、session常用操作

$_SESSION 等价于 Yii::app()->session;

2.1.1、写入session

//启动session

$session=new CHttpSession;
$session->open();
Yii::app()->session[ 'key' ] = 'value'

2.1.2、读取session

Yii::app()->session[ 'key' ]

2.1.3、获取session的ID

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

2.1.4、销毁session

//移去所有session变量

Yii::app()->session->clear();

//移去存储在服务器端的数据

Yii::app()->session->destroy();

2.1.5、session高级用法

$session = Yii::app()->session;
$session [ 'key' ] = 'value' ;
var_dump( $session [ 'key' ]);

2.2 cookie

2.2.1 设置cookie

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

2.2.2 读取cookie

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

2.2.3 销毁cookie

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