String url = "详情请咨询富友对接群";
        InteOrdQryReqData ord = new InteOrdQryReqData();
        ord.setMchnt_cd("0001000F0040992");
        ord.setOrder_date("20200519");
        ord.setOrder_id("124512121");
        JSONObject jsonParam = JSONObject.fromObject(ord);  
     JSONObject responseJSONObject = httpPost(url, jsonParam.toString());    
}

响应内容：{“resp_code”:”0000”,”resp_desc”:”成功”,”mchnt_cd”:”商户代码”…..}
