Yii --Command 任务处理

1.配置，执行任务所需要的组件
任务配置文件：/protected/config/console.php
配置方法跟配置main文件差不多[html]
 
// This is the configuration for yiic console application. 
// Any writable CConsoleApplication properties can be configured here. 
return array( 
    'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..', 
    'name'=>'My Console Application', 
    // application components 
 
    // 自动载入的模型和组件类 
    'import'=>array( 
            'application.models.*',//载入"application/models/"文件夹下的所有模型类 
            'application.components.*',//载入"application/components/"文件夹下的所有应用组件类 
            'application.extensions.*',//载入"application/extensions/"文件夹下的所有应用组件类 
    ), 
 
    'components'=>array( 
            // uncomment the following to use a MySQL database 
            'db'=>array( 
                    'connectionString' => 'mysql:host=localhost;dbname=dbname',//连接mysql数据库 
                    'emulatePrepare' => true, 
                    'username' => 'root',//MySQL数据库用户名 
                    'password' => '123456',//MySQL数据库用户密码 
                    'charset' => 'utf8',//MySQL数据库编码 
                    'tablePrefix' => 'zd_', //MySQL数据库表前缀 
                    'enableProfiling'=>true, 
                    'enableParamLogging'=>true, 
            ), 
            //加载Email组件 
            'mailer' => array( 
                    'class'     => 'application.extensions.mailer.EMailer', 
            ), 
    ), 
); 

// This is the configuration for yiic console application.
// Any writable CConsoleApplication properties can be configured here.
return array(
 'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
 'name'=>'My Console Application',
 // application components

 // 自动载入的模型和组件类
 'import'=>array(
   'application.models.*',//载入"application/models/"文件夹下的所有模型类
   'application.components.*',//载入"application/components/"文件夹下的所有应用组件类
   'application.extensions.*',//载入"application/extensions/"文件夹下的所有应用组件类
 ),

 'components'=>array(
   // uncomment the following to use a MySQL database
   'db'=>array(
     'connectionString' => 'mysql:host=localhost;dbname=dbname',//连接mysql数据库
     'emulatePrepare' => true,
     'username' => 'root',//MySQL数据库用户名
     'password' => '123456',//MySQL数据库用户密码
     'charset' => 'utf8',//MySQL数据库编码
     'tablePrefix' => 'zd_', //MySQL数据库表前缀
     'enableProfiling'=>true,
     'enableParamLogging'=>true,
   ),
   //加载Email组件
   'mailer' => array(
     'class'     => 'application.extensions.mailer.EMailer',
   ),
 ),
);2.任务文件
放在 /protected/commands/ 文件目录下继承 CConsoleCommand 基类的为任务文件 命名方法为   任务名称+Command
例如 GoCommand.php[html] 
 
/** 
 * 自动运行文件 
 */ 
class GoCommand  extends CConsoleCommand 
{ 
 
 
    /** 
     * 死循环输出 
     */ 
    public function run(){ 
         
        for($i=1;$i>0;$i++){ 
            self::echoWord($i); 
            sleep(2);//休眠2秒 
             
            //跳出 
            if(i==500){ 
                break; 
            } 
        } 
    } 
 
    /** 
     * 输出hollo word 
     */ 
    public function echoWord($i){ 
        echo "hollo word --$i\n"; 
    } 
} 

/**
 * 自动运行文件
 */
class GoCommand  extends CConsoleCommand
{

 /**
  * 死循环输出
  */
 public function run(){
  
  for($i=1;$i>0;$i++){
   self::echoWord($i);
   sleep(2);//休眠2秒
   
   //跳出
   if(i==500){
    break;
   }
  }
 }

 /**
  * 输出hollo word
  */
 public function echoWord($i){
  echo "hollo word --$i\n";
 }
}3.执行任务
打开命令行工具，进入项目的/protected 目录下 输入yiic命令即出现提示，提示列表显示刚才写的任务文件[html] 
E:\project\app\protected>yiic
