口碑订单预咨询接口详解

说明： 
ISV下单前，可以通过此接口咨询用户优惠信息。 

交互UI示例： 

需要注意的点： 
1.apdid_token参数为用户设备信息，接口使用方法如下：

// 获取用户信息设备       AlipayJSBridge.call('getO2ODeviceToken', {           appName: 'kb_isv_110229',           appKey:'98y6VvdaDLpoqWZw'           },           function (result) {               //回调               //alert(result.appToken);           });

这里需要注意的是appName，appKey参数不需要改变它们的值！！！ 
result数据结构：

1、调用失败： {"error":xxx,"errorMessage":"xxx"}2、调用成功： {'appToken':'xxxssajkjkjkxdkwqkqwb'}

2.goods_info参数中quantity（商品数量），price（商品单价）参数需要满足quantity * price = total_amount，否则接口会报错，报错示例如下：

{"koubei_trade_order_consult_response":{"code":"40004","msg":"Business Failed","sub_code":"INVALID_PARAMETER","sub_msg":"参数有误单品总金额：0.03不能超过订单金额:0.01"},"sign":"iWhTXJRc72PK+AwSKcQGoA206NL8E47Ob9TtqQA6jCSJO02+6dJNm3D3Jg8D7jYKwpFrMndqI50ZWnUgfghjp57CaLD/6ULoOS3V0MFg1XvP+d/ay7h/CAqWd5uAZlUJXmpfRHzLj4hmdfq/sHeqjNUvoSYeYgF9I718HbG033ZhIR/N/OzV2kaxox2ywVvMmdKgoiD0jrWZ2ggFVe/mwJ7pgpwgQisiEMHV0h1bn+95wzGelA1THOhj0M57VRdKWpoag=="}

3.返回参数discount_detail参数中id参数一般有两种格式:

"discount_detail":[           {               "discount_type":"M_DISCOUNT",               "id":"1801220004000998509",//这种格式一般是活动id,一般是不需要用户领取的               "is_hit":"false",               "is_purchased":"false",               "name":"1.1折"           },           {               "discount_type":"M_DISCOUNT",               "id":"VOUCHER_DC_VOUCHER_DEFAULT_NULL_2018021100073002403700UQOVTK",               //这种格式一般是优惠券id，需要用户领取               "is_hit":"false",               "is_purchased":"false",               "name":"1.2折"           }       ],

代码示例：

AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do",        AlipayConfig.app_id,AlipayConfig.merchant_private_key,"json","GBK",AlipayConfig.alipay_public_key,"RSA2");  KoubeiTradeOrderConsultRequest request = new KoubeiTradeOrderConsultRequest();request.setBizContent("{" +"\"request_id\":\"20180206134530999\"," +"\"user_id\":\"2088712969xxxxxx\"," +"\"total_amount\":0.01," +"\"undiscountable_amount\":0," +"\"shop_id\":\"2017080300077000000044490772\"," +"\"goods_info\":[{" +"\"goods_id\":\"wuhuo1996\"," +"\"goods_name\":\"武霍專用\"," +"\"goods_category\":\"201701000\"," +"\"quantity\":\"1\"," +"\"price\":0.01" +"}]," +"\"apdid_token\":\"e6yhhS3s6I0rFtB2f/y3doGNY27x0hFzu6vKSPROjXiiVKVYSn108AIxG1H/4SML0pRXZ1DY3b/jG6vWv/eP/GYLmzbKxbqISg8LoyaA29T5oq+ENu3vD6HsClPwHlggetqN4kw3UQxemf5oWuQ/k7oEg4N+amtEzih+hNkTvKLLE5oU0N98wW++uxQWUtNh5N/WRtH0Ric7bMbAc6dYfuc4rbcIaPWgKSr9MPyJa6P11eXzP69/aY34RvAemxg==\"" +"}");KoubeiTradeOrderConsultResponse response;try {    response = alipayClient.execute(request);    if(response.isSuccess()){        System.out.println("调用成功"+response.getBody());        } else {        System.out.println("调用失败"+response.getBody());        }} catch (AlipayApiException e) {    // TODO Auto-generated catch block    e.printStackTrace();}finally {      }
