swoft 切面AOP尝试

作者:互联网

 

官网文档 https://www.swoft.org/documents/v2/basic-components/aop/

视频教程 https://www.bilibili.com/video/BV12J411j721?p=51

切面 我理解 就是不破坏原有代码逻辑,往里面加入需要执行的前置 后置 操作

 

定义切面类  app\Aspect\TestAspect.php

指定方法切入的

<?php

namespace App\Aspect;
use Swoft\Aop\Annotation\Mapping\After;
use Swoft\Aop\Annotation\Mapping\Aspect;
use Swoft\Aop\Annotation\Mapping\Before;
use Swoft\Aop\Annotation\Mapping\PointExecution;

/**
 * @Aspect()
 * @PointExecution(include={"App\Http\Controller\HomeController::hi.*"})
 */
class TestAspect
{
	/**
	 * @Before()
	 */
	public function before()
	{
		echo "我是前置".PHP_EOL;
	}

	/**
	 * @After()
	 */
	public function after()
	{
		echo "我是后置".PHP_EOL;
	}
}

  

浏览器访问 /hi 

控制台输出

我是前置
我是后置

  

访问hello 控制台不会触发 不会打印

如果改为 

/**
* @Aspect()
* @PointExecution(include={"App\Http\Controller\HomeController::h.*"})
*/
就会触发了



通过使用连接点 joinpoint可以拿到执行方法的参数 返回值等 可以放到前置 做鉴权 后置 做日志
<?php

namespace App\Aspect;
use Swoft\Aop\Annotation\Mapping\After;
use Swoft\Aop\Annotation\Mapping\AfterReturning;
use Swoft\Aop\Annotation\Mapping\Aspect;
use Swoft\Aop\Annotation\Mapping\Before;
use Swoft\Aop\Annotation\Mapping\PointExecution;
use Swoft\Aop\Point\JoinPoint;
use Swoft\Http\Message\Request;

/**
 * @Aspect()
 * @PointExecution(include={"App\Http\Controller\HomeController::h.*"})
 */
class TestAspect
{
    /**
     * @Before()
     * @param JoinPoint $joinPoint
     */
    public function before(JoinPoint $joinPoint)
    {
        echo "我是前置".PHP_EOL;
        /** @var Request $request */
        $request = $joinPoint->getArgs()[0];
        $params = $request->getQueryParams(); //可以用来做鉴权
        var_dump($params);
    }

    /**
     * @After()
     */
    public function after()
    {
        echo "我是后置".PHP_EOL;
    }

    /**
     * @AfterReturning()
     * @param JoinPoint $joinPoint
     * @param $request Request
     */
    public function afterrunning(JoinPoint $joinPoint)  // 可以日志记录
    {

        echo "程序执行完了".PHP_EOL;
//        /** @var Request $request */
//        $request = $joinPoint->getArgs()[0];
//        $params = $request->getBody();
//        var_dump($params);

        return $joinPoint->getReturn();
    }
}

 

访问浏览器  结果如下 

HTTP Server Start Success!
2020/07/18-19:42:54 [INFO] Swoft\Server\Server:startSwoole(491) Swoole\Runtime::enableCoroutine
2020/07/18-19:42:54 [INFO] Swoft\Listener\BeforeStartListener:handle(27) Server extra info: pidFile @runtime/swoft.pid

Server start success (Master PID: 16459, Manager PID: 16464)
我是前置
array(1) {
  ["id"]=>
  string(1) "4"
}
我是后置
程序执行完了
