自定义异常处理返回的 JSON 格式

其实，把你的 App\Exceptions\Handler 的 protected function convertExceptionToArray(Exception $e){} 方法覆盖掉即可完美的重写异常响应 json 格式

    /**
     * Convert the given exception to an array.
     *
     * @param  \Exception  $e
     * @return array
     */
    protected function convertExceptionToArray(Exception $e)
    {
        $code = $e->getCode();
        if ($e instanceof HttpException) {
            $code = $e->getStatusCode();
        }
        return config('app.debug') ? [
            'success' => false,
            'code' => $code,
            'message' => $e->getMessage(),
            'exception' => get_class($e),
            'file' => $e->getFile(),
            'line' => $e->getLine(),
            'trace' => collect($e->getTrace())->map(function ($trace) {
                return Arr::except($trace, ['args']);
            })->all(),
        ] :[
            'success' => false,
            'code' => $code,
            'message' => $this->isHttpException($e) ? $e->getMessage() : 'Server Error',
        ];
    }
