Error and exception interception

Http controller error exception

An error occurs in the http controller, the system will use the default exception handling to output to the client, the code is as follows:

<?php
protected function hookThrowable(\Throwable $throwable,Request $request,Response $response)
{
    if(is_callable($this->httpExceptionHandler)){
        call_user_func($this->httpExceptionHandler,$throwable,$request,$response);
    }else{
        $response->withStatus(Status::CODE_INTERNAL_SERVER_ERROR);
        $response->write(nl2br($throwable->getMessage()."\n".$throwable->getTraceAsString()));
    }
}

Can override the onException method directly on the controller:

<?php
namespace App\HttpController;
use App\ViewController;
use EasySwoole\Http\AbstractInterface\Controller;
use EasySwoole\Http\Message\Status;
class Base extends ViewController
{
    function index()
    {
        // TODO: Implement index() method.
        $this->actionNotFound('index');
    }
    function onException(\Throwable $throwable): void
    {
        var_dump($throwable->getMessage());
    }
    protected function actionNotFound(?string $action): void
    {
        $this->response()->withStatus(Status::CODE_NOT_FOUND);
        $this->response()->write('action not found');
    }
}

Can also customize exception handling files:

<?php
namespace App;
use EasySwoole\Http\Request;
use EasySwoole\Http\Response;
class ExceptionHandler
{
    public static function handle( \Throwable $exception, Request $request, Response $response )
    {
        var_dump($exception->getTraceAsString());
    }
}

DI registration exception handling in the initialize event:

public static function initialize()
{
    Di::getInstance()->set(SysConst::HTTP_EXCEPTION_HANDLER,[ExceptionHandler::class,'handle']);
}
