        TokenParameter tokenParameter = TokenParameter.self()
                .clientId("")
                .clientSecret("xxxx")
                .grantId("4xxx267")
                .refresh(true)
                .build();
        OAuthToken oAuthToken = yzClient.getOAuthToken(tokenParameter);
        Token token = new Token( oAuthToken.getAccessToken());
        System.out.println(token.getAccessToken());
        // 传入参数
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("goods_id",609186196);
        jsonObject.put("num",1);
        YouzanTradeBillGoodsUrlGet youzanTradeBillGoodsUrlGet = new YouzanTradeBillGoodsUrlGet();
        //创建参数对象,并设置参数
        YouzanTradeBillGoodsUrlGetParams youzanTradeBillGoodsUrlGetParams = new YouzanTradeBillGoodsUrlGetParams();
        youzanTradeBillGoodsUrlGetParams.setKdtId(4xxxx267L);
        youzanTradeBillGoodsUrlGetParams.setOrderFrom("cart");
        youzanTradeBillGoodsUrlGetParams.setOrderType(0);
        System.out.println(jsonObject.toJSONString());
        JSONArray jsonArray = new JSONArray();
        jsonArray.add(jsonObject);
        youzanTradeBillGoodsUrlGetParams.setItemList(jsonArray.toJSONString());
        youzanTradeBillGoodsUrlGet.setAPIParams(youzanTradeBillGoodsUrlGetParams);
        YouzanTradeBillGoodsUrlGetResult result = yzClient.invoke(youzanTradeBillGoodsUrlGet, token, YouzanTradeBillGoodsUrlGetResult.class);
        JSONObject jsonObject1  = JSON.parseObject(JSON.toJSONString(result.getData()));
        System.out.println(jsonObject1);

说明：

• 如果 token 没有 refresh 参数，则需要更新 SDK，参考文档 https://doc.youzanyun.com/doc#/content/27032/27651

• 传入的参数是可选的，比如 sku 信息，如果没有可以不传

• 该接口需要在有赞云后台类目能力 中去申请
