GO麻烦！面向方面的框架 [英] Troubles with GO! Aspect-Oriented Framework

问题描述

如果有人使用GO！框架，您能帮我吗. 我在php 5.3.13上安装框架.演示示例正在工作. 但是我自己的例子不起作用.没有执行Aspect(MethodExecution之前的方法).

If someone work with GO! framework, can you help me. I install framework on php 5.3.13. Demo example is working. But my own example doesn't work. Aspect(method beforeMethodExecution) is not perfomed.

这是我的代码.

主文件:

//1 Include kernel and all classes
if (file_exists(__DIR__ .'/../../vendor/autoload.php')) {
     $loader = include __DIR__ .'/../../vendor/autoload.php';
}
// 2 Make own ascpect kernel

use Go\Core\AspectKernel;
use Go\Core\AspectContainer;

class Kernel extends AspectKernel{
  /**
   * Configure an AspectContainer with advisors, aspects and pointcuts
   *
   * @param AspectContainer $container
   *
   * @return void
   */
   public function configureAop(AspectContainer $container)
  {
  }
}

//3 Initiate aspect kernel

$Kernel = Kernel::getInstance();

$Kernel->init();

//4 Include aspect
include(__DIR__.'/aspectclass/AspectClass.php');

$aspect = new DebugAspect();

//5 register aspect
$Kernel->getContainer()->registerAspect($aspect);


//6 Include test class

include(__DIR__.'/class/class1.php'); 


//7 Execute test class

$Class = new General('test');
$Class->publicHello();

具有测试类的文件:

class General{
protected $message = '';

public function __construct($message)
{
    $this->message = $message;
}

public function publicHello()
{
    echo 'Hello, you have a public message: ', $this->message, "<br>", PHP_EOL;
}

}

具有方面的文件:

use Go\Aop\Aspect;
use Go\Aop\Intercept\FieldAccess;
use Go\Aop\Intercept\FunctionInvocation;
use Go\Aop\Intercept\MethodInvocation;
use Go\Lang\Annotation\After;
use Go\Lang\Annotation\Before;
use Go\Lang\Annotation\Around;
use Go\Lang\Annotation\Pointcut;
use Go\Lang\Annotation\DeclareParents;
use Go\Lang\Annotation\DeclareError;

class DebugAspect implements Aspect{

/**
 * Method that should be called before real method
 *
 * @param MethodInvocation $invocation Invocation
 * @Before("execution(General->*(*))")
 *
 */
public function beforeMethodExecution(MethodInvocation $invocation)
{
    $obj = $invocation->getThis();
    echo 'Calling Before Interceptor for method: ',
    is_object($obj) ? get_class($obj) : $obj,
    $invocation->getMethod()->isStatic() ? '::' : '->',
    $invocation->getMethod()->getName(),
    '()',
    ' with arguments: ',
    json_encode($invocation->getArguments()),
    PHP_EOL;
}


}

推荐答案

您知道，go-aop不是PHP扩展，因此它无法转换直接通过require或include加载的类. .在内部，它试图即时覆盖源代码，但是它应该收到一个控件(通过与composer或自定义autoloader类集成).

As you know, go-aop isn't a PHP extension, so it couldn't transform classes that were loaded directly via require or include. Internally it tries to overwrite the source code on-the-fly, but it should receive a control (via integration with composer or custom autoloader class).

因此，您在这里遇到错误:

So, you have an error here:

//6 Include test class
include(__DIR__.'/class/class1.php');

您已将此类显式加载到内存中，并且无法从用户空间对其进行转换.要将控件传递给框架，您应该明确地进行此操作.看这行 AopComposerLoader .php#L99 了解其工作原理.在这里，我们通过流源过滤器包含了源文件，该文件将控制权传递给了框架，它可以转换类以编织方面.

You explicitly load this class into memory and there is no way to transform it from userland. To pass a control to the framework, you should make this explicitly. Look at the line AopComposerLoader.php#L99 to have an idea how it works. Here we include a source file via the stream source filter that pass control to the framework and it can transform the class to weave an aspects.

要修正您的示例，只需将include更改为以下内容:

To fix your example just change an include to the following:

include (FilterInjectorTransformer::rewrite(__DIR__.'/class/class1.php'));
