iap调起支付返回 Payment_appleiap:返回订单信息失败,http://ask.dcloud.net.cn/article/282

复制http://ask.dcloud.net.cn/article/497的调起支付,itunes connect已添加app内购买项目,只是状态为“准备提交”,是在itunes connect申请证书并且打包测试的。
代码如下：
document.getElementById("btn_pay").addEventListener('tap',function() {
pay("balance_six");
});

    var iapChannel;  
        var IAPOrders = ['balance_six'];  

        mui.plusReady(function() {  
            // 获取支付通道  
            plus.payment.getChannels(function(channels){  
                for (var i in channels) {  
                     alert(channels[i].id);  
                    if (channels[i].id == 'appleiap') {  
                         alert(4);  
                        iapChannel = channels[i];  
                        iapChannel.requestOrder(IAPOrders, function(event) {  
                            for (var index in event) {  
                                var OrderItem = event[index];  
                                alert("Title:" + OrderItem.title + "Price:" + OrderItem.price + "Description:" + OrderItem.description + "ProductID:" + OrderItem.productid);  
                            }  
                        }, function(errormsg) {  

//这里报错
alert("获取支付通道失败：" + errormsg.message);
});
}
}
}, function(e) {
alert("获取支付通道失败：" + e.message);
});
})
function pay(id) {
plus.payment.request(iapChannel, {
"productid": id,
"username": "appusername",
"quantity": 1
}, function(result) {
alert(JSON.stringify(result));
}, function(e) {
plus.nativeUI.alert("更多错误信息请参考支付(Payment)规范文档：http://www.html5plus.org/#specification#/specification/Payment.html", null, "支付失败：" + e.code);
});
