java版微信和支付宝退款接口

这篇文章主要为大家详细介绍了java版微信退款接口和java版支付宝退款接口，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

本文实例为大家分享了java微信退款接口和支付宝退款接口的具体代码，供大家参考，具体内容如下

1、微信退款接口 

相对来说我感觉微信的退款接口还是比较好调用的，直接发送httppost请求即可；

/** * * 微信退款 * @param transaction_id 微信支付订单号 * @param out_refund_no 商户订单号 * @param total_fee 总金额 * @param refund_fee 退款金额 * @param op_user_id 操作人 * @return String * @exception */ public String wxPayrefundRequest(String transaction_id, String out_refund_no, int total_fee, int refund_fee, String op_user_id) { CloseableHttpClient httpclient = null; CloseableHttpResponse response = null; String strResponse = null; try { httpclient = ClientCustomSSL.getCloseableHttpClient(); // 构造HTTP请求 HttpPost httpPost = new HttpPost(Configure.PAY_refund_API); // PayrefundReqData wxdata = new PayrefundReqData( // "1004720096201602263541023415", "16371", 30, 30, "19417"); PayrefundReqData wxdata = new PayrefundReqData(transaction_id, out_refund_no, total_fee, refund_fee, op_user_id); String requestStr = Util.ConvertObj2Xml(wxdata); StringEntity se = new StringEntity(requestStr.toString()); httpPost.setEntity(se); // 发送请求 response = httpclient.execute(httpPost); httpentity entity = response.getEntity(); if (entity != null) { SAXReader saxReader = new SAXReader(); Document document = saxReader.read(entity.getContent()); Element rootElt = document.getRootElement(); // 结果码 String returnCode = rootElt.elementText("return_code"); String resultCode = rootElt.elementText("result_code"); if ("SUCCESS".equals(returnCode)&&"SUCCESS".equals(resultCode)) { strResponse=returnCode; }else { strResponse=rootElt.elementText("err_code_des"); } } EntityUtils.consume(entity); } catch (Exception e) { Logger.getLogger(getClass()).error("payrefundRequest", e); } finally { try { response.close(); httpclient.close(); } catch (IOException e) { // Todo Auto-generated catch block Logger.getLogger(getClass()).error("payrefundRequest关闭异常:", e); } } return strResponse; }

报错的话请检查加密的sign是否正确，还有就是调用的接口地址是否正确

2、支付宝退款接口 

支付宝直接导入支付宝封装好的jar包直接调用即可，官网下载地址

调用方法:

/** * * 支付宝退款请求 * @param out_Trade_no 订单支付时传入的商户订单号,不能和 Trade_no同时为空。 * @param Trade_no 支付宝交易号，和商户订单号不能同时为空 * @param refund_amount 需要退款的金额，该金额不能大于订单金额,单位为元，支持两位小数 * @return * String * @exception */ public String alipayrefundRequest(String out_Trade_no,String Trade_no,double refund_amount){ // 发送请求 String strResponse = null; try { AlipayClient alipayClient = new DefaultAlipayClient (AlipayConfig.alipayurl,AlipayConfig.appid, AlipayConfig.private_key,AlipayConfig.content_type,AlipayConfig.input_charset,AlipayConfig.ali_public_key); AlipayTraderefundRequest request = new AlipayTraderefundRequest(); AlipayrefundInfo alidata= new AlipayrefundInfo(); alidata.setout_Trade_no(out_Trade_no); alidata.setrefund_amount(refund_amount); alidata.setTrade_no(Trade_no); request.setBizContent(JsonUtils.convertToString(alidata)); AlipayTraderefundResponse response = alipayClient.execute(request); strResponse=response.getCode(); if ("10000".equals(response.getCode())) { strResponse="退款成功"; }else { strResponse=response.getSubMsg(); } } catch (Exception e) { Logger.getLogger(getClass()).error("alipayrefundRequest", e); } return strResponse; }
