laravel 使用dingo api 添加sql调试

1、在appServiceProvider启动boot中添加

 if(env("APP_DEBUG"))DB::enableQueryLog();

2、在需要调试的地方直接使用：

dd(DB::getQueryLog());

以下采用更加优雅的方式实现（配合debugbar）：

前提：需要安装debugbar扩展

1、添加json返回处理的中间件 ProcessJsonResponse

namespace AppHttpMiddleware;
    use Closure;
    use DingoApiHttpResponse;

    class ProcessJsonResponse
    {
        /**
         * Handle an incoming request.
         *
         * @param  IlluminateHttpRequest  $request
         * @param  Closure  $next
         * @return mixed
         */
        public function handle($request, Closure $next)
        {
            $response = $next($request);
            if (
                env("APP_DEBUG")&&
                $request->ajax()&&
                $response instanceof Response &&
                app()->bound('debugbar') &&
                app('debugbar')->isEnabled()
            ) {
                $debugbar_data=app('debugbar')->getData();
                $queries_data = $this->sqlFilter($debugbar_data);
                $total_duration_time=array_get($debugbar_data, 'time.duration_str');
                $response->setContent(json_decode($response->morph()->getContent(), true) + [
                        '_debugbar' => [
                            'total_queries' => count($queries_data),
                            'total_duration_time'=>$total_duration_time,
                            'queries' => $queries_data,
                        ]
                    ]);
            }

            return $response;
        }

        /**
         * Get only sql and each duration
         *
         * @param $debugbar_data
         * @return array
         */
        protected function sqlFilter($debugbar_data) {
            $result = array_get($debugbar_data, 'queries.statements');

            return array_map(function ($item) {
                return [
                    'sql' => array_get($item, 'sql'),
                    'duration' => array_get($item, 'duration_str'),
                ];
            }, $result);
        }
    }

2、修改配置文件api.php添加全局中间件控制（也可以参照laravel自行添加路由中间件）

'middleware' => [
        AppHttpMiddlewareProcessJsonResponse::class,//dingo api 接口返回内容添加sql by winston
    ],

 效果：
