Ask a master about the export of excel from phpexcel

when phpexcel exports excel, both the server and the local file are exported. Why does the excel on my server have data, the local one is blank, and there is nothing left?

$param = [

]
            "uid" => 2120872
        ];
        $order = Jdbc::getMemberDate("new_order",$param,2);

        $objPHPExcel = new \PHPExcel();
        // 
        $objSheet = $objPHPExcel->getActiveSheet();
        // title
        $objSheet->setTitle("XXXXXXX");
        // 
        $objSheet->setCellValue("A1","oid")
                 ->setCellValue("B1","uid")
                 ->setCellValue("C1","bespeak_store_id")
                 ->setCellValue("D1","store_id")
                 ->setCellValue("E1","cartid")
                 ->setCellValue("F1","order_number")
                 ->setCellValue("G1","price")
                 ->setCellValue("H1","order_time")
                 ->setCellValue("I1","good_number")
                 ->setCellValue("J1","type");
        $j = 2;
        foreach ($order as $k => $v){
            $objSheet->setCellValue("A".$j,$v["oid"])
                     ->setCellValue("B".$j,$v["uid"])
                     ->setCellValue("C".$j,$v["bespeak_store_id"])
                     ->setCellValue("D".$j,$v["store_id"])
                     ->setCellValue("E".$j,$v["cartid"])
                     ->setCellValue("F".$j,$v["order_number"])
                     ->setCellValue("G".$j,$v["price"])
                     ->setCellValue("H".$j,$v["order_time"])
                     ->setCellValue("I".$j,$v["good_number"])
                     ->setCellValue("J".$j,$v["type"]);
            $jPP;
        }
        $file_name = "order".date("Y-m-d",time()).".xls";
        $response = $this->response();
        $response->withHeader("Cache-Control","public");
        $response->withHeader("Content-Type","application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
        $response->withHeader("Content-Type","application/octet-stream");
        $response->withHeader("Content-Type","application/download");
        $response->withHeader("Content-Transfer-Encoding","binary");
        $response->withHeader("Last-Modified","" . gmdate("D, d M Y H:i:s") . "GMT");
        $response->withHeader("Cache-Control","must-revalidate, post-check=0, pre-check=0");
        $response->withHeader("Pragma","no-cache");
        $response->withHeader("Content-Type","application/download");
        $response->withHeader("Content-Disposition","attachment;filename=".$file_name."");
        $xlsWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, "Excel5");
        $xlsWriter->save($file_name); // "php://output"
