这篇文章主要介绍了ThinkPHP权限认证Auth实例,需要的朋友可以参考下
本文以实例代码的形式深入剖析了ThinkPHP权限认证Auth的实现原理与方法,具体步骤如下:
mysql数据库部分sql代码:
-- ---------------------------- -- Table structure for think_auth_group -- ---------------------------- DROP TABLE IF EXISTS `think_auth_group`; CREATE TABLE `think_auth_group` ( `id` mediumint(8) unsigned NOT NULL AUTO_INCREMENT, `title` char(100) NOT NULL DEFAULT '', `status` tinyint(1) NOT NULL DEFAULT '1', `rules` char(80) NOT NULL DEFAULT '', PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COMMENT='用户组表'; -- ---------------------------- -- Records of think_auth_group -- ---------------------------- INSERT INTO `think_auth_group` VALUES ('1', '管理组', '1', '1,2'); -- ---------------------------- -- Table structure for think_auth_group_access -- ---------------------------- DROP TABLE IF EXISTS `think_auth_group_access`; CREATE TABLE `think_auth_group_access` ( `uid` mediumint(8) unsigned NOT NULL COMMENT '用户id', `group_id` mediumint(8) unsigned NOT NULL COMMENT '用户组id', UNIQUE KEY `uid_group_id` (`uid`,`group_id`), KEY `uid` (`uid`), KEY `group_id` (`group_id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COMMENT='用户组明细表'; -- ---------------------------- -- Records of think_auth_group_access -- ---------------------------- INSERT INTO `think_auth_group_access` VALUES ('1', '1'); INSERT INTO `think_auth_group_access` VALUES ('1', '2'); -- ---------------------------- -- Table structure for think_auth_rule -- ---------------------------- DROP TABLE IF EXISTS `think_auth_rule`; CREATE TABLE `think_auth_rule` ( `id` mediumint(8) unsigned NOT NULL AUTO_INCREMENT, `name` char(80) NOT NULL DEFAULT '' COMMENT '规则唯一标识', `title` char(20) NOT NULL DEFAULT '' COMMENT '规则中文名称', `status` tinyint(1) NOT NULL DEFAULT '1' COMMENT '状态:为1正常,为0禁用', `type` char(80) NOT NULL, `condition` char(100) NOT NULL DEFAULT '' COMMENT '规则表达式,为空表示存在就验证,,不为空表示按照条件验证', PRIMARY KEY (`id`), UNIQUE KEY `name` (`name`) ) ENGINE=MyISAM AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 COMMENT='规则表'; -- ---------------------------- -- Records of think_auth_rule -- ---------------------------- INSERT INTO `think_auth_rule` VALUES ('1', 'Home/index', '列表', '1', 'Home', ''); INSERT INTO `think_auth_rule` VALUES ('2', 'Home/add', '添加', '1', 'Home', ''); INSERT INTO `think_auth_rule` VALUES ('3', 'Home/edit', '编辑', '1', 'Home', ''); INSERT INTO `think_auth_rule` VALUES ('4', 'Home/delete', '删除', '1', 'Home', ''); DROP TABLE IF EXISTS `think_user`; CREATE TABLE `think_user` ( `id` int(11) NOT NULL, `username` varchar(30) DEFAULT NULL, `password` varchar(32) DEFAULT NULL, `age` tinyint(2) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; -- ---------------------------- -- Records of think_user -- ---------------------------- INSERT INTO `think_user` VALUES ('1', 'admin', '21232f297a57a5a743894a0e4a801fc3', '25');
配置文件Application\Common\Conf\config.php部分:
'配置值' 'DB_DSN' => '', // 数据库连接DSN 用于PDO方式 'DB_TYPE' => 'mysql', // 数据库类型 'DB_HOST' => 'localhost', // 服务器地址 'DB_NAME' => 'thinkphp', // 数据库名 'DB_USER' => 'root', // 用户名 'DB_PWD' => 'root', // 密码 'DB_PORT' => 3306, // 端口 'DB_PREFIX' => 'think_', // 数据库表前缀 'AUTH_CONFIG' => array( 'AUTH_ON' => true, //认证开关 'AUTH_TYPE' => 1, // 认证方式,1为时时认证;2为登录认证。 'AUTH_GROUP' => 'think_auth_group', //用户组数据表名 'AUTH_GROUP_ACCESS' => 'think_auth_group_access', //用户组明细表 'AUTH_RULE' => 'think_auth_rule', //权限规则表 'AUTH_USER' => 'think_user'//用户信息表 ) );
项目Home控制器部分Application\Home\Controller\IndexController.class.php代码:
check($name, $uid, $type, $mode, $relation)) { die('认证:成功'); } else { die('认证:失败'); } } }
以上这些代码就是最基本的验证代码示例。
下面是源码阅读:
1、权限检验类初始化配置信息:
$Auth = new \Think\Auth();
创建一个对象时程序会合并配置信息
程序会合并Application\Common\Conf\config.php中的AUTH_CONFIG数组
public function __construct() { $prefix = C('DB_PREFIX'); $this->_config['AUTH_GROUP'] = $prefix . $this->_config['AUTH_GROUP']; $this->_config['AUTH_RULE'] = $prefix . $this->_config['AUTH_RULE']; $this->_config['AUTH_USER'] = $prefix . $this->_config['AUTH_USER']; $this->_config['AUTH_GROUP_ACCESS'] = $prefix . $this->_config['AUTH_GROUP_ACCESS']; if (C('AUTH_CONFIG')) { //可设置配置项 AUTH_CONFIG, 此配置项为数组。 $this->_config = array_merge($this->_config, C('AUTH_CONFIG')); } }
2、检查权限:
check($name, $uid, $type = 1, $mode = 'url', $relation = 'or')
大体分析一下这个方法
首先判断是否关闭权限校验 如果配置信息AUTH_ON=>false 则不会进行权限验证 否则继续验证权限
if (!$this->_config['AUTH_ON']) { return true; }
获取权限列表之后会详细介绍:
$authList = $this->getAuthList($uid, $type);
此次需要验证的规则列表转换成数组:
if (is_string($name)) { $name = strtolower($name); if (strpos($name, ',') !== false) { $name = explode(',', $name); } else { $name = array($name); } }
所以$name参数是不区分大小写的,最终都会转换成小写
开启url模式时全部转换为小写:
if ($mode == 'url') { $REQUEST = unserialize(strtolower(serialize($_REQUEST))); }
权限校验核心代码段之一,即循环所有该用户权限 判断 当前需要验证的权限 是否 在用户授权列表中:

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
