Question

我使用laravel5.5作为网络程序。但是当程序异常时，中间件不起作用。

我该怎么做呢？

我的中间件代码是list：

namespace App\Http\Middleware;

use Closure;


class ApiException
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @param  string|null  $guard
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $response = $next($request);
        $env = config('app.env');
        $statusCode = $response->getSatusCode();
        if ($statusCode >= 500 && $env != 'dev') {
            $response->setContent(['error' => 'Internal Server Error']);
        }

        return $next($request);
    }
}

谢谢你的帮助！

// Create and display the custom field in product general setting tab add_action( 'woocommerce_product_options_general_product_data', 'add_custom_field_general_product_fields' ); function add_custom_field_general_product_fields(){ global $post; echo '<div class="product_custom_field">'; // Custom Product Checkbox Field woocommerce_wp_checkbox( array( 'id' => '_disabled_for_coupons', 'label' => __('Disabled for coupons', 'woocommerce'), 'description' => __('Disable this products from coupon discounts', 'woocommerce'), 'desc_tip' => 'true', ) ); echo '</div>';; } // Save the custom field and update all excluded product Ids in option WP settings add_action( 'woocommerce_process_product_meta', 'save_custom_field_general_product_fields', 10, 1 ); function save_custom_field_general_product_fields( $post_id ){ $current_disabled = isset( $_POST['_disabled_for_coupons'] ) ?

在中间件中不能但是在Exception / Handler中可以..

任何时候发生异常..它没有进入中间件，它进入了Exception / Handler.php ..

在渲染方法

中

public function render($request, Exception $exception)
{
        if ($exception->getCode() >= 500 ||) {
            //return redirect()->route(); do something here
        }

        return parent::render($request, $exception);
}

如何拉中间件，当laravel例外
