Kohana之COOKIE及SESSION使用

http://www.cnblogs.com/liushannet/archive/2010/08/19/1803209.htmlCookie使用:

<?phpecho Cookie::salt("abc","def");#得到保存到客户端的字符#下面几个不解释~echo Cookie::get("abc");Cookie::set("abc","def");Cookie::delete("abc");

?

SESSION使用

类型有三个 (native,cookie,database)

默认是native(就是本地,PHP默认的)

其中database 配置

在APP的config里建立一个session.php文件

内容为:

<?phpreturn array('database' => array(

                 /** * Database settings for session storage. * * string   group  configuation group name * string   table  session table name * integer  gc     number of requests before gc is invoked * columns  array  custom column names */'group'   => 'default','table'   => 'sessions','gc'      => 500,'columns' => array(/** * session_id:  session identifier * last_active: timestamp of the last activity * contents:    serialized session data */'session_id'  => 'session_id','last_active' => 'last_active','contents'    => 'contents'),),);

建立数据表:(和你配置的数据库配置有关系,下面描述)

CREATE TABLE  `sessions` (        `session_id` VARCHAR( 24 ) NOT NULL,       `last_active` INT UNSIGNED NOT NULL,        `contents` TEXT NOT NULL,        PRIMARY KEY ( `session_id` ),        INDEX ( `last_active` )    ) ENGINE = MYISAM ;

其中cookie 配置

?

<?phpreturn array('cookie' => array('encrypted' => FALSE,//设置为true需要配置encrypted),);

?encrypted 配置在相同目录下建立encrypt.php

<?phpreturn array("default"=>array("key"=>"dddd",//你的密钥"mode"=>"ecb",//加密方式,在PHP网站可以找到"cipher"=>MCRYPT_RIJNDAEL_128,//加密方式,在PHP网站可以找到 ));

?如果使用native就最方便啦,不用配置在这里随便提下数据库配置吧在同目录下建立database.php

<?php defined('SYSPATH') or die('No direct access allowed.');return array('default' => array('type'       => 'pdo','connection' => array(/** * The following options are available for PDO: * * string   dsn         Data Source Name * string   username    database username * string   password    database password * boolean  persistent  use persistent connections? */'dsn'        => 'mysql:host=localhost;dbname=****','username'   => 'root','password'   => '******','persistent' => FALSE,),/** * The following extra options are available for PDO: * * string   identifier  set the escaping identifier */'table_prefix' => 'ko_','charset'      => 'utf8','caching'      => FALSE,'profiling'    => TRUE,),);

?

以下是使用方式

<?phpSession::instance("cookie")->set("abc","abcd");echo Session::instance("cookie")->get("abc");Session::instance("cookie")->delete("abc");Session::instance("cookie")->destroy();//清除SESSION

你可以把COOKIE去掉或者使用database试试,用database你会发现数据的sessions表会多一条记录

本地方式的话可以留空 即为:Session::instance();

修改Kohana_Session的$default为你想要的默认方式,除了在控制器头上设置不知道还有其他地方设置没,有点不方便,

在不修改它源代码的情况下~
