Laravel9.x 自定义error Handling处理

Laravel9.x 自定义error Handling

在app/Exceptions目录下,新建ApiHandler自定义异常，用于返回json格式异常

<?php

namespace App\Exceptions;
use Exception;
use Throwable;

class ApiHandler extends Exception
{
    /**
     * @param string $message
     * @param int $code
     * @param Throwable|null $previous
     */
    public function __construct($message = "", $code = 500, Throwable $previous = null)
    {
        parent::__construct($message, $code, $previous);
    }
}

注册自定异常到app/Exceptions/Handler.php文件的register方法中

/**
     * Register the exception handling callbacks for the application.
     *
     * @return void
     */
    public function register()
    {
       
        // 注册自定义ApiHandler
        $this->renderable(function (ApiHandler $e) {
            return response()->json(['message' => $e->getMessage()], $e->getCode());
        });

        $this->reportable(function (Throwable $e) {
            //
        });
    }

在route/api.php路由下， 测试

Route::post('/test', function() {
  throw new ApiHandler('test throw handler');
});
