//参数
// $postdata['scene']="nidaodaodao";
$postdata['scene']=$cardid;
// 宽度
$postdata['width']=430;
// 页面

}二、php调用方法$page='pages/postcard/postcard';
$cardid="10";
$class = new \app\api\controller\Spreadcode();
$mpcodeimg=$class->mpcode($page,$cardid);
$dataret['mpcodeimg']=$mpcodeimg;
$this->assign('retdata',$dataret);三、前端页面调用<img src="data:{$retdata['mpcodeimg']}" />
