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     /**

 33      * 是否是组件

 34      * 

 35      * @param string $id

 36      * @return bool

 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     /**

 74      * 获取属性

 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 company\components.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。
