我在 Laravel 5.2 中创建了一个自定义异常类。它运行良好,直到 laravel 5.4。
当我尝试使用与 laravel 5.5相同的自定义异常类时,它会引发以下错误。
Type error: Argument 1 passed to App\Utility\Exceptions\CustomException::report() must be an instance of Exception, none given, called in /var/www/html/bubbles/vendor/laravel/framework/src/Illuminate/Foundation/Exceptions/Handler.php on line 102 {"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Type error: Argument 1 passed to App\\Utility\\Exceptions\\CustomException::report() must be an instance of Exception, none given, called in /var/www/html/bubbles/vendor/laravel/framework/src/Illuminate/Foundation/Exceptions/Handler.php on line 102 at /var/www/html/bubbles/app/Utility/Exceptions/CustomException.php:39)
这是我一直在使用的自定义异常类
<?php
namespace App\Utility\Exceptions;
use Illuminate\Support\Facades\Lang;
use Exception;
class CustomException extends Exception
{
private $error_code = NULL;
private $error_info = NULL;
function __construct($type = NULL, $errors = NULL)
{
$this->error_code = $type['error_code'];
$this->error_info = $errors;
$message = Lang::get('exceptions.'.$this->error_code);
parent::__construct($message, $type['code'], NULL);
}
public function report(Exception $exception)
{
parent::report($exception);
}
public function getErrorCode()
{
return $this->error_code;
}
public function getErrorInfo()
{
return $this->error_info;
}
}
// end of class CustomException
// end of file CustomException.php
谁能解释我为什么抛出参数必须是异常实例?任何帮助将不胜感激。
