phalcon的CLI应用
CLI应用是命令行下执行的程序, 可以应用于定时任务,守护进程, 脚本, 公用命令等等.
最小的目录结构:
app/config/config.php
app/tasks/MainTask.php
app/cli.php <– main bootstrap file
创建bootstrap
use Phalcon\DI\FactoryDefault\CLI as CliDI;
use Phalcon\CLI\Console as ConsoleApp;
define('VERSION', '1.0.0');
//Using the CLI factory default services container
$di = new CliDI();
// Define path to application directory
defined('APPLICATION_PATH')
|| define('APPLICATION_PATH', realpath(dirname(__FILE__)));
/**
* Register the autoloader and tell it to register the tasks directory
*/
$loader = new \Phalcon\Loader();
$loader->registerDirs(
array(
APPLICATION_PATH . '/tasks'
)
);
$loader->register();
// Load the configuration file (if any)
if(is_readable(APPLICATION_PATH . '/config/config.php')) {
$config = include APPLICATION_PATH . '/config/config.php';
$di->set('config', $config);
}
//Create a console application
$console = new ConsoleApp();
$console->setDI($di);
/**
* Process the console arguments
*/
$arguments = array();
$params = array();
foreach($argv as $k => $arg) {
if($k == 1) {
$arguments['task'] = $arg;
} elseif($k == 2) {
$arguments['action'] = $arg;
} elseif($k >= 3) {
$params[] = $arg;
}
}
if(count($params) > 0) {
$arguments['params'] = $params;
}
// define global constants for the current task and action
define('CURRENT_TASK', (isset($argv[1]) ? $argv[1] : null));
define('CURRENT_ACTION', (isset($argv[2]) ? $argv[2] : null));
try {
// handle incoming arguments
$console->handle($arguments);
}
catch (\Phalcon\Exception $e) {
echo $e->getMessage();
exit(255);
}
命令行下启用用例:
$ php app/cli.php
任务
cli应用至少要有一个默认的任务mainTask和一个默认的行为:mainAction.
class mainTask extends \Phalcon\CLI\Task {
public function mainAction() {
echo "\nThis is the default task and the default action \n";
}
/**
* @param array $params
*/
public function testAction(array $params) {
echo sprintf('hello %s', $params[0]) . PHP_EOL;
echo sprintf('best regards, %s', $params[1]) . PHP_EOL;
}
}
命令:
$ php app/cli.php main test world universe
hello world
best regards, universe
任务链:
要支持任务链首先定义DI:
$di->setShared('console', $console);
try {
// handle incoming arguments
$console->handle($arguments);
}
然后就可以使用控制台的任何任务了:
class MainTask extends \Phalcon\CLI\Task {
public function mainAction() {
echo "\nThis is the default task and the default action \n";
$this->console->handle(array(
'task' => 'main',
'action' => 'test'
));
}
public function testAction() {
echo '\nI will get printed too!\n';
}
}
