一、发送现金红包

1、发送普通红包接口

private static String sendRedPackUrl = "https://api.mch./mmpaymkttransfers/sendredpack";/*** 发送红包* @param params 请求参数* @param certPath 证书文件目录* @param partner 证书密码* @return {String}*/public static String sendRedPack(Map<String, String> params, String certPath, String partner) {return HttpUtils.postSSL(sendRedPackUrl, PaymentKit.toXml(params), certPath, partner);}

2、发送裂变红包接口

private static String sendGroupRedPackUrl = "https://api.mch./mmpaymkttransfers/sendgroupredpack";/*** 发送裂变红包* @param params 请求参数* @param certPath 证书文件目录* @param partner 证书密码* @return {String}*/public static String sendGroupRedPack(Map<String, String> params, String certPath, String partner) {return HttpUtils.postSSL(sendGroupRedPackUrl, PaymentKit.toXml(params), certPath, partner);}

查询红包记录

1.接口封装

private static String getHBInfo = "https://api.mch./mmpaymkttransfers/gethbinfo ";/*** 根据商户订单号查询信息* @param params 请求参数* @param certPath 证书文件目录* @param partner 证书密码* @return {String}*/public static String getHbInfo(Map<String, String> params, String certPath, String partner) {return HttpUtils.postSSL(getHBInfo, PaymentKit.toXml(params), certPath, partner);}

2.具体实现封装

/*** 根据商户订单号查询红包* @param mch_billno 商户订单号* @param partner 商户号* @param wxappid 公众账号ID* @param paternerKey 商户签名Key* @param certPath 证书路径* @return*/public static String query(String mch_billno,String partner,String wxappid,String paternerKey,String certPath) {Map<String, String> params = new HashMap<String, String>();// 随机字符串params.put("nonce_str", System.currentTimeMillis() / 1000 + "");// 商户订单号params.put("mch_billno", mch_billno);// 商户号params.put("mch_id", partner);// 公众账号IDparams.put("appid", wxappid);params.put("bill_type", "MCHT");//创建签名String sign = PaymentKit.createSign(params, paternerKey);params.put("sign", sign);String xmlResult = RedPackApi.getHbInfo(params, certPath, partner);Map<String, String> result = PaymentKit.xmlToMap(xmlResult);System.out.println(result);return JsonKit.toJson(result);}
