• yii模块下面的组件


    模块的定义就不写了,直接进入主题看目录和文件:

    application/modules/client/controllers/UserController.php

     1 <?php
     2 
     3 class UserController extends ClientController
     4 {
     5     public function init()
     6     {
     7         parent::init();
     8     }
     9 
    10     public function actionIndex()
    11     {
    12         $userid = $this->user->userid;
    13         $test = $this->user->test;
    14         $test1 = $this->user->test();
    15         exit('xx');
    16     }

    $this->user找不到,它会去ClientController中找

    application/modules/client/components/ClientController.php

     1 <?php
     2 class ClientController extends CController
     3 { 
     4     public function init()
     5     {
     6         header('Content-type:text/html;charset=utf-8');
     7         Yii::import('ext.functions', true); //加载公共函数
     8         //$this->getUserId();   
     9     }
    10     public function __get($name)
    11     {
    12         return Yii::app()->client->$name;
    13     }

    找到__get($name)方法,返回的是全局的client组件

    application/config/main.php

     1 <?php
     2 
     3 ……
     4 
     5 'components'=>array(
     6             'client' => array(
     7                    'class' => 'application.modules.client.components.Client',
     8             ),
     9 ……
    10 ),

    配置好client组件,然后指定到

    application/modules/client/components/Client.php
      1 <?php
      2 
      3 use Yii;
      4 
      5 class Client extends ApiComponent
      6 {
      7     
      8     private static $_params;
      9     
     10     private $_components;
     11     
     12     private $_propertys;
     13     
     14     private static $instance;
     15     
     16     public function __construct()
     17     {
     18         self::$instance =& $this;
     19     }
     20     
     21     public static function &getInstance()
     22     {
     23         return self::$instance;
     24     }
     25     
     26     public function init()
     27     {
     28 
     29     }
     30     
     31     
     32     /**

     37      */
     38     public function hasComponent($id)
     39     {
     40         return isset(self::$_coreComponents[$id]);
     41     }
     42     
     43     /**
     44      * 获取组件
     45      * @param string $id
     46      */
     47     public function getComponent($id)
     48     {
     49         if (isset($this->_components[$id]))
     50         {
     51             return $this->_components[$id];
     52         }
     53         
     54         if (isset(self::$_coreComponents[$id]))
     55         {
     56             $component = Yii::createComponent(self::$_coreComponents[$id]);
     57             $component->owner = $this;
     58             $component->init();
     59             $this->_components[$id] = $component;
     60             return $component;
     61         }
     62     }
     63     
     64     /**
     65      * 
     66      * @param integer $id
     67      */
     68     public function HasProperty($id)
     69     {
     70         return isset(self::$_propertysMap[$id]);
     71     }
     72     
     73     /**

     75      * @param string $id
     76      */
     77     public function getProperty($id)
     78     {
     79         if (isset($this->_propertys[$id]))
     80         {
     81             return $this->_propertys[$id];
     82         }
     83     
     84         if (isset(self::$_propertysMap[$id]))
     85         {
     86             list($component, $key) = explode('.', self::$_propertysMap[$id]);
     87             $this->_propertys[$id] = $this->$component->$key;
     88         }
     89         return $this->_propertys[$id];
     90     }
     91     
     92     /**
     93      * 设置属性
     94      */
     95     public function setProperty($id, $value)
     96     {
     97         if (isset(self::$_propertysMap[$id]))
     98         {
     99             list($component, $key) = explode('.', self::$_propertysMap[$id]);
    100             $this->$component->$key = $value;
    101         }
    102     }
    103     
    104     /**
    105      * 清除缓存
    106      * @param string $id
    107      */
    108     public function clearProperty($id)
    109     {
    110         unset($this->_propertys[$id]);
    111     }
    112     
    113     /**
    114      * (non-PHPdoc)
    115      * @see companycomponents.CompanyComponent::__get()
    116      */
    117     public function __get($name)
    118     {
    119         //组件
    120         if ($this->hasComponent($name))
    121         {
    122             return $this->getComponent($name);
    123         }
    124     
    125         //属性
    126         if ($this->HasProperty($name))
    127         {
    128             return $this->getProperty($name);
    129         }
    130     
    131         return parent::__get($name);
    132     }
    133     
    134     /**
    135      * 
    136      * @param unknown_type $name
    137      * @param unknown_type $value
    138      */
    139     public function __set($name, $value)
    140     {
    141         //属性
    142         if ($this->HasProperty($name))
    143         {
    144             return $this->setProperty($name, $value);
    145         }
    146         
    147         return parent::__set($name, $value);
    148     }
    149     
    150     public function __call($name, $parameters)
    151     {
    152         return parent::__call($name, $parameters);
    153     }
    154     
    155     private static $_coreComponents = array(
    156         'user' => array(
    157             'class' => 'application.modules.client.components.User'
    158         ),
    159     );
    160     
    161     private static $_propertysMap = array(
    162         'userid'            => 'user.userid',
    163     );
    164     
    165 }
    可以从中看到定义好的user组件以及快捷获取user组件下面的userid属性
    application/modules/client/components/user.php
     1 <?php
     2 
     3 class User extends ApiComponent
     4 {
     5     function getXzcoin()
     6     {
     7         
     8     }
     9     
    10     function getTest()
    11     {
    12         var_dump('safafaf');
    13         return '1';
    14         
    15     }
    16     
    17     function Test($name = 0){
    18         echo $name;19         return 'test';
    20     }
    21     
    22     function getUserid(){
    23         echo '222';
    24         return '2';
    25     }
    26 }


    以及用到的application/modules/client/components/ApiComponent.php
     1 <?php
     2 
     3 use CComponent;
     4 
     5 abstract class ApiComponent extends CComponent
     6 {
     7     
     8     public $owner;
     9     
    10     protected $_is;
    11     
    12     protected $_g;
    13     
    14     protected $_cacheGetter    = TRUE;
    15     
    16     public function init()
    17     {
    18         
    19     }
    20     
    21     /**
    22      * 
    23      * @param unknown_type $name
    24      */
    25     public function __get($name)
    26     {
    27         if (strncasecmp($name, 'is', 2) === 0 && method_exists($this, $name))
    28         {
    29             $name = strtolower($name);
    30             if ( ! isset($this->_is[$name]))
    31             {
    32                 $this->_is[$name] = $this->$name();
    33             }
    34             return $this->_is[$name];
    35         }
    36         
    37         $getter = 'get' . ucfirst($name);
    38         
    39         if (method_exists($this, $getter))
    40         {
    41             if ($this->_cacheGetter)
    42             {
    43                 if (isset($this->_g[$name]))
    44                 {
    45                     return $this->_g[$name];
    46                 }
    47                 $this->_g[$name] = $this->$getter();
    48                 return $this->_g[$name];
    49             }
    50             
    51             return $this->$getter();
    52         }
    53             
    54         return parent::__get($name);
    55     }
    56     
    57     /**
    58      * 
    59      * @throws Exception
    60      */
    61     public function throwException($message, $code = 0)
    62     {
    63         throw new Exception($message, $code);
    64     }
    65     
    66 }

    完毕。
