$face_filter = config('terminal.face_filter');
$filterArr = explode(',',$face_filter);
foreach ($result['orderGoods'] as $key=>$val){
    $badword = array_combine($filterArr,array_fill(0,count($filterArr),'***'));
    $detail = strtr($val['detail'], $badword);
    $result['orderGoods'][$key]['detail'] = !empty($detail) ? $detail : $val['detail'];
