YII console 定时脚本

可以用来做定时程序通过命令运行代码，非url访问方式更安全

linux/macos 上使用yiic配置（window上使用yiic.bat）

1.yiic要有执行权限，chmod -R 777 yiic

2.yiic用的PHP，需要指定PHP的正确路径：

#!/usr/bin/env php会自动的在你的用户PATH变量中所定义的目录中寻找php来执行的。

用vi打开yiic,把“#!/usr/bin/env php” 改为“#!/usr/local/php/bin/php(也就是你php路径）

也可以>/usr/local/bin/php yiic

 

1.yiic 命令用到的是yiic.php,也可以直接用yiic.php
2.控制台的命令配置文件是应用的protected/config/console.php文件，

<?php
define('ROOT_PATH' , "/Users/apple/development/pyq_tuiguang/");

$yii    = '/sites/www/yii/framework/yiic.php';
$config = ROOT_PATH . 'protected/config/console.php';

require_once($yii);
Yii::createWebApplication($config)->run();

系统默认的路径是protected/commands/shell 如果你执行单一的任务,直接在run方法里面写，另外一种就是同写你的Controller(控制器),前面增加actionXXX

protected/extensions/clean_command/ECleanCommand.php

<?php
class ECleanCommand extends CConsoleCommand
{
	public $webRoot = null;
	public function getHelp()
	{
		$out = "Clean command allows you to clean up various temporary data Yii and an application are generating.\n\n";
		return $out.parent::getHelp();
	}
	public function actionCache()
	{
		$cache=Yii::app()->getComponent('cache');
		if($cache!==null){
			$cache->flush();
			echo "Done.\n";
		}
		else {
			echo "Please configure cache component.\n";
		}
	}
	public function actionAssets()
	{
		if(empty($this->webRoot))
		{
			echo "Please specify a path to webRoot in command properties.\n";
			Yii::app()->end();
		}
		$this->cleanDir($this->webRoot.'/assets');
		echo "Done.\n";
	}
	public function actionRuntime()
	{
		$this->cleanDir(Yii::app()->getRuntimePath());
		echo "Done.\n";
	}
	private function cleanDir($dir)
	{
		$di = new DirectoryIterator ($dir);
		foreach($di as $d)
		{
			if(!$d->isDot())
			{
				echo "Removed ".$d->getPathname()."\n";
				$this->removeDirRecursive($d->getPathname());
			}
		}
	}
	private function removeDirRecursive($dir)
	{
		$files = glob($dir.'*', GLOB_MARK);
		foreach ($files as $file)
		{
			if (is_dir($file))
			$this->removeDirRecursive($file);
			else
			unlink($file);
		}
		if (is_dir($dir))
		rmdir($dir);
	}
}

 console.php,commandMap配置后不需要指定yiic shell index.php

<?php

// 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',
    'import'=>array( //可以使用model等
        'application.models.*',
        'application.components.*',
    ),
    'components'=>array( 
        'db'=>require(dirname(__FILE__) . '/db.php')
    ),
    'commandMap' => array(
        'clean' => array(
            'class' => 'ext.clean_command.ECleanCommand',
            'webRoot' => 'E:\Apache2\htdocs\webapp', //注意修改 class::webRoot
        ),
        'rbac' => array(
            'class' => 'application.commands.shell.RbacCommand',
        )
    ),
);

命令行运行cd E:\Apache2\htdocs\webapp\protected\ 进入yiic.php的目录

yiic clean

Usage: E:\Apache2\htdocs\webapp\protected\yiic.php clean <action>
Actions:
    cache
    assets
    runtime

yiic.php clean cache
yiic clean assets

E:\Apache2\htdocs\webapp\protected>yiic clean assets
Removed E:\Apache2\htdocs\webapp/assets\1f5cfc05
Removed E:\Apache2\htdocs\webapp/assets\836290cc
Done.

yiic clean runtime

单一任务

<?php
class TestCommand extends CConsoleCommand
{
	public function getHelp()
	{
        //php.exe crons.php help test
	    return '这里显示命令的帮助信息';
	}

	/**
	 * Execute the action.
	 * @param array command line parameters specific for this command
	 */
	public function run($args)
	{
		if(!isset($args[0]))
			$this->usageError('请输入参数.');
		echo('你输入的参数是 :\n');
		var_dump($args);
		return 1; #必须返回数字
	}
}

 /www/yii_dev/testwebap/protected/ yiic test p1 p2 p3
你输入的参数是 :\narray(3) {
  [0]=>string(2) "p1"
  [1]=>string(2) "p2"
  [2]=>string(2) "p3"
}

yii  crontab 作业方法

yii consolecommand 控制台命令，实现定时任务。当然，这得结合系统，如XP的计划任务，linux的crontab命令 打开你的linux命令窗口，创建自动任务。至于windows系统 ，是计划任务（win系统，可以谷歌如何操作），下面只讲linux系统。

crontab -e
##然后输入
1 * * * *  php /具体地址/protected/yiic.php Test >>/具体地址/protected/commands/test.log

'CException' with message 'Property "CConsoleApplication.user" is not defined.' 在console程序中不能用CWebUser，shell程序中调用到Yii::app()->user会报错
