异常处理

示例：

<?php
namespace EasySwoole;
use EasySwoole\Core\Component\Di;
use EasySwoole\Core\Component\SysConst;
use EasySwoole\Core\Http\Request;
use EasySwoole\Core\Http\Response;
use EasySwoole\Core\Swoole\EventRegister;
use EasySwoole\Core\Swoole\ServerManager;
use EasySwoole\Core\AbstractInterface\EventInterface;
class EasySwooleEvent implements EventInterface
{
    public static function frameInitialize() : void
    {
        Di::getInstance()->set( SysConst::HTTP_EXCEPTION_HANDLER, \App\ExceptionHandler::class );
    }
    .....
}

\App\ExceptionHandler 文件

<?php
namespace App;
use EasySwoole\Core\Http\AbstractInterface\ExceptionHandlerInterface;
use EasySwoole\Core\Http\Request;
use EasySwoole\Core\Http\Response;
class ExceptionHandler implements ExceptionHandlerInterface
{
    public function handle( \Throwable $exception, Request $request, Response $response )
    {
        var_dump($exception);
    }
}

试试在控制器里，随便实例化一个不存在的类，如：new B() 让其报错下试试。
注意：长连接时请做好异常处理，因为在mysql断开时会抛出错误中断运行，这时捕获下重新连接再执行sql语句。
