thinkphp6的自定义异常处理

框架支持异常处理由开发者自定义类进行接管，需要在app目录下面的provider.php文件中绑定异常处理类，例如：

 Request::class,
//    'thinkexceptionHandle' => ExceptionHandle::class,//原来的异常
    'thinkexceptionHandle' => '\app\exception\ExecptionHandle'
];

然后再app下面新建一个exception文件夹放自定义错误信息

msg = $e->getMessage() ?: $this->msg;
        //HttpExceptions是继承同级目录下HttpExceptions，代码在下方
        if ($e instanceof HttpExceptions) {
            $this->httpCode = $e->getStatusCode() ?: $this->httpCode;
        }
        $this->errorCode = $e->getCode() ?: $this->errorCode;
        $result_data = [
            'message' => $this->msg,
            'data' => [],
            'code' => $this->errorCode
        ];
        return json($result_data, $this->httpCode);

        // 其他错误交给系统处理
        return parent::render($request, $e);
    }

}

同级目录下HttpExceptions 文件

statusCode = $statusCode;
        $this->headers    = $headers;

        parent::__construct($message, $code, $previous);
    }

    public function getStatusCode()
    {
        return $this->statusCode;
    }

    public function getHeaders()
    {
        return $this->headers;
    }
}

调用

use appexceptionHttpExceptions;
throw new HttpExceptions(404,"自定义错误",'444');
