Hyperf captures PHP error levels, such as notice, warning and error, and returns them to the front-end

1. register listener

Config/autoload/listeners.php is as follows

return [

Hyperf\exceptionhandler\listener\errorexception handler:: class, error_reporting() Error level listener.

Refer to the listener chapter on the official website https://hyperf.wiki/2.2/#/zh -cn/exception-handler

2. Register global Middleware

Now configure the middleware under config/autoload/middleware.php



namespace App\Middleware\Auth;

use Psr\Container\ContainerInterface;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Server\MiddlewareInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\RequestHandlerInterface;
use Hyperf\HttpServer\Contract\ResponseInterface as HttpResponse;

class FooMiddleware implements MiddlewareInterface
     * @var ContainerInterface
    protected $container;
     * @var HttpResponse
    protected $response;

    public function __construct(ContainerInterface $container, HttpResponse $response)
        $this->container = $container;
        $this->response = $response;

    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
        try {
            return $handler->handle($request);
        } catch (\Throwable $throwable) {
            return $this->response->json(
                    'code' => -1,
                    'message' => $throwable->getMessage(),
                    'data' => [


After completing the above steps, you can return PHP error prompts such as notice to the front end, and the PHP program will not continue to execute.
