错误与异常拦截

http控制器错误异常

在http控制器中出现错误,系统将使用默认异常处理进行输出至客户端,代码如下:

  1. <?php
  2. protected function hookThrowable(\Throwable $throwable,Request $request,Response $response)
  3. {
  4.     if(is_callable($this->httpExceptionHandler)){
  5.         call_user_func($this->httpExceptionHandler,$throwable,$request,$response);
  6.     }else{
  7.         $response->withStatus(Status::CODE_INTERNAL_SERVER_ERROR);
  8.         $response->write(nl2br($throwable->getMessage()."\n".$throwable->getTraceAsString()));
  9.     }
  10. }

可直接在控制器重写onException方法:

  1. <?php
  2. namespace App\HttpController;
  4. use App\ViewController;
  5. use EasySwoole\Http\AbstractInterface\Controller;
  6. use EasySwoole\Http\Message\Status;
  8. class Base extends ViewController
  9. {
  11.     function index()
  12.     {
  13.         // TODO: Implement index() method.
  14.         $this->actionNotFound('index');
  15.     }
  17.     function onException(\Throwable $throwable): void
  18.     {
  19.         var_dump($throwable->getMessage());
  20.     }
  22.     protected function actionNotFound(?string $action): void
  23.     {
  24.         $this->response()->withStatus(Status::CODE_NOT_FOUND);
  25.         $this->response()->write('action not found');
  26.     }
  27. }

也可自定义异常处理文件:

  1. <?php
  2. namespace App;
  4. use EasySwoole\Http\Request;
  5. use EasySwoole\Http\Response;
  7. class ExceptionHandler
  8. {
  9.     public static function handle( \Throwable $exception, Request $request, Response $response )
  10.     {
  11.         var_dump($exception->getTraceAsString());
  12.     }
  13. }

在initialize事件中DI注册异常处理:

  1. public static function initialize()
  2. {
  3.     Di::getInstance()->set(SysConst::HTTP_EXCEPTION_HANDLER,[ExceptionHandler::class,'handle']);
  4. }
