微擎系统卡券领取

 

下面是模板页面单击领取卡券的，加了一个参数outer_str，这样领取返回时就多了一个参数outer_str（这里返回没有下滑线了），可以作为场景的来源参照，nimei_str那个不用的也可以

{php echo register_jssdk(false);}
<script>
    function jumpCardUrl(){
        // alert("{$cardArry['openid']}");
        // alert("{$cardArry['timestamp']}");
        // alert("{$cardArry['nonceStr']}");
        // alert("{$cardArry['signature']}");
        // alert("{$cardArry['cardId']}");
     wx.addCard({

    cardList: [
         {
            cardId: '{$cardArry['cardId']}',

           cardExt: '{"code": "", "openid": "{$cardArry['openid']}", "timestamp": "{$cardArry['timestamp']}","nonce_str":"{$cardArry['nonceStr']}", "signature":"{$cardArry['signature']}","outer_str":"{$outerstr}","nimei_str":"rw_22_33"}'
           
        }

    ], // 需要添加的卡券列表
     success: function (res) {
        }

     }); 
    }

</script>

 php页面  卡券场景来源变量 就不说了根据实际情况查询   $cardinfo,$openid分别是卡券cardid和用户openid，用户openid不正确好像也可以的

$cardArry = getCard($cardinfo,$openid);
function getCard($card_id,$openid){

     global $_W,$_GPC;

     //获取access_token

　　领取成功，核销   返回信息都是在api.php里面

有一个在卡券页面点击第一个使用的核销不是在api里面，在其他文件
