# 命令行应用(Command Line Applications)
# 命令行应用(Command Line Applications)
CLI应用即是运行在命令行窗体上的应用。 主要用来实现后台任务, 命令行工具等。
### 结构(Structure)
最小结构的CLI程序如下:
- app/config/config.php
- app/tasks/MainTask.php
- app/cli.php <– 主要启动文件
### 创建引导(Creating a Bootstrap)
普通的MVC程序中,启动文件用来启动整个应用。和web应用不同, 此处应用中我们使用cli.php来作为启动文件。
下面是一个简单的启动文件示例:
```
<pre class="calibre14">```
<?php
use Phalcon\DI\FactoryDefault\CLI as CliDI,
Phalcon\CLI\Console as ConsoleApp;
define('VERSION', '1.0.0');
// 使用CLI工厂类作为默认的服务容器
$di = new CliDI();
// 定义应用目录路径
defined('APPLICATION_PATH')
|| define('APPLICATION_PATH', realpath(dirname(__FILE__)));
/**
* 注册类自动加载器
*/
$loader = new \Phalcon\Loader();
$loader->registerDirs(
array(
APPLICATION_PATH . '/tasks'
)
);
$loader->register();
// 加载配置文件(如果存在)
if (is_readable(APPLICATION_PATH . '/config/config.php')) {
$config = include APPLICATION_PATH . '/config/config.php';
$di->set('config', $config);
}
// 创建console应用
$console = new ConsoleApp();
$console->setDI($di);
/**
* 处理console应用参数
*/
$arguments = array();
foreach ($argv as $k => $arg) {
if ($k == 1) {
$arguments['task'] = $arg;
} elseif ($k == 2) {
$arguments['action'] = $arg;
} elseif ($k >= 3) {
$arguments['params'][] = $arg;
}
}
// 定义全局的参数, 设定当前任务及动作
define('CURRENT_TASK', (isset($argv[1]) ? $argv[1] : null));
define('CURRENT_ACTION', (isset($argv[2]) ? $argv[2] : null));
try {
// 处理参数
$console->handle($arguments);
} catch (\Phalcon\Exception $e) {
echo $e->getMessage();
exit(255);
}
```
```
上面的代码可以使用如下方式执行:
```
<pre class="calibre14">```
$ php app/cli.php
这样程序会直接执行默认的任务及默认动作.
```
```
### 任务(Tasks)
这里的任务同于web应用中的控制器。 任一 CLI 应用程序都至少包含一个mainTask 及一个 mainAction, 每个任务至少有一个mainAction, 这样在使用者未明确的 指定action时 此mainAction就会执行。
下面即是一个mainTask的例子( app/tasks/MainTask.php ):
```
<pre class="calibre14">```
<?php
class MainTask extends \Phalcon\CLI\Task
{
public function mainAction()
{
echo "\nThis is the default task and the default action \n";
}
}
```
```
### 处理动作参数(Processing action parameters)
CLI应用中, 开发者也可以在action中处理传递过来的参数, 下面的例子中已经对传递过来的参数进行了处理。
如果你使用下面的参数和动作运行应用程序:
```
<pre class="calibre14">```
<?php
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;
}
}
```
```
我们可以使用下面的命令行及参数执行程序:
```
<pre class="calibre14">```
$ php app/cli.php main test world universe
hello world
best regards, universe
```
```
### 链中运行任务(Running tasks in a chain)
CLI应用中可以在一个action中执行另一action. 要实现这个需要在 DI 中设置console.
```
<pre class="calibre14">```
<?php
$di->setShared('console', $console);
try {
// Handle incoming arguments
$console->handle($arguments);
} catch (\Phalcon\Exception $e) {
echo $e->getMessage();
exit(255);
}
```
```
然后开发者即可在一个action中使用用其它的action了. 下面即是例子:
```
<pre class="calibre14">```
<?php
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";
}
}
```
```
当然, 通过扩展 `Phalcon\Cli\Task` 来实现如上操作会是一个更好主意。
