问题原因

拼接的领劵链接有误导致

解决方案

核实拼接的领劵链接是否有误，详细的拼接规则说明如下：

1、支付APP内引导访问领劵链接，拼接规则如下：

https://render.alipay.com/p/s/mygrace/ndetail.html?webview_options=sms%3DYES%26pd%3DNO&type=VOUCHER&id=券id（voucher_id发券成功后接口同步返回商户）

完整的示例如下（以voucher_id=2017101200073002254500AVEV0E为例）：

https://render.alipay.com/p/s/mygrace/ndetail.html?webview_options=sms%3DYES%26pd%3DNO&type=VOUCHER&id=2017101200073002254500AVEV0E

2、支付宝APP外引导添加：拼接规则如下：

完整的示例如下（以voucher_id=2017101200073002254500AVEV0E为例）：

https://render.alipay.com/p/s/i/?scheme=alipays%3A%2F%2Fplatformapi%2Fstartapp%3FappId%3D20000067%26url%3Dhttps%3A%2F%2Frender.alipay.com%2Fp%2Fs%2Fmygrace%2Fndetail.html%3F__webview_options__%3Dsms%253DYES%2526pd%253DNO%26type%3DVOUCHER%26id%3D2017101200073002254500AVEV0E

注：发劵调用成功后，劵实际已经到用户支付宝账号内，访问领劵链接进行领取的目的，主要是把该劵添加在卡包内，便于用户进行查看。
