GO的麻烦!面向方面的框架


Troubles with GO! Aspect-Oriented Framework

如果有人用GO!框架,你能帮我吗?我在php 5.3.13上安装框架。演示示例正在工作。但我自己的例子行不通。Aspect(method beforemethodexexecution)未执行

这是我的代码。

主要文件:

//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();

测试类文件:

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;
}

}

aspect:

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;
}

}

你知道,go-aop不是PHP扩展,所以它不能转换直接通过requireinclude加载的类。在内部,它尝试动态地覆盖源代码,但它应该接收一个控件(通过与composer或自定义自动加载器类的集成)。

这里有一个错误:

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

你显式地将这个类加载到内存中,并且没有办法从userland转换它。要将控件传递给框架,您应该显式地这样做。查看AopComposerLoader.php#L99行,了解它是如何工作的。这里我们通过流源过滤器包含一个源文件,它将控制权传递给框架,它可以转换类来编织方面。

要修复您的示例,只需将include更改为以下内容:

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