yii2.0框架中session与cookie的用法

Posted 2020-07-20 不解凡忧

我们在开发项目中南面使用到session给和cookie，那么在yii中有他自己的规则
如下案例：
 

session使用
    function actionS1(){
        echo $this->id."
";
        echo $this->action->id."
";
        设置session,通过session组件来设置
        Yii::app()->session[‘username‘] = "zhangsan";
        Yii::app()->session[‘useraddr‘] = "beijing";
        echo "make session success";
    }
   
    function actionS2(){
        使用session
        echo Yii::app()->session[‘username‘],"
";
        echo Yii::app()->session[‘useraddr‘];
        echo "use session success";
    }
   
    function actionS3(){
        删除一个session
        unset(Yii::app()->session[‘useraddr‘]);
       
        删除全部session
        Yii::app()->session->clear();  //删除session变量
        Yii::app()->session->destroy(); //删除服务器的session信息
    }
   
   cookie在Yii框架使用
    function actionC1(){
        设置cookie
        $ck = new CHttpCookie(‘hobby‘,‘篮球，足球‘);
        $ck -> expire = time()+3600;
        把$ck对象放入cookie组件里边
        Yii::app()->request->cookies[‘hobby‘] = $ck;
       
        $ck2 = new CHttpCookie(‘sex‘,‘nan‘);
        $ck2 -> expire = time()+3600;
        把$ck对象放入cookie组件里边
        Yii::app()->request->cookies[‘sex‘] = $ck2;
       
        echo "cookie make success";
    }
    function actionC2(){
        访问cookie
        echo Yii::app()->request->cookies[‘hobby‘],"
";
        echo Yii::app()->request->cookies[‘sex‘];
    }
    function actionC3(){
        删除cookie
        unset(Yii::app()->request->cookies[‘sex‘]);
    }
