Kohana之COOKIE及SESSION使用

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

<?php
echo 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:

<?php
return

 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

<?

php

return

 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

<?

php
return

 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

<?

php
Session::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~
