所有的接口支持沙盒环境的测试

1、前言

前面几篇文件详细介绍了 支付宝提现、扫码支付、条码支付、Wap支付、App支付

• 支付宝支付-提现到个人支付宝

• 支付宝支付-扫码支付

• 支付宝支付-刷卡支付(条码支付)

• 支付宝Wap支付你了解多少？

• Android版-支付宝APP支付

• 一张二维码集成微信、支付宝支付

其中也断断续续的提到了一些接口。本片文章主要是总结支付宝支付中常用的一些接口

2、常用的接口总结

这里使用表格的方式列出 官方接口列表以及详细的参数说明

3、使用服务端SDK封装接口

3.1 服务端SDK下载及其使用方法

参考 开放平台服务端SDK

Maven项目引用JAR包可以参考 支付宝Wap支付你了解多少？ 里面有详细的介绍

重要说明
1、接口使用的编码格式为 UTF-8
2、接口数据交互使用的是 json
3、接口加密的模式使用官方推荐的 RSA2
4、本片文章主要是介绍Java的使用方法与封装

3.2 初始化SDK

在SDK调用前需要进行初始化

AlipayClient alipayClient = new DefaultAlipayClient(URL, APP_ID, APP_PRIVATE_KEY, FORMAT, CHARSET, ALIPAY_PUBLIC_KEY, SIGN_TYPE);

关键参数说明：

3.3 API接口封装

3.3.1 alipay.trade.query接口封装

该接口提供所有支付宝支付订单的查询，商户可以通过该接口主动查询订单状态，完成下一步的业务逻辑。 需要调用查询接口的情况： 当商户后台、网络、服务器等出现异常，商户系统最终未接收到支付通知； 调用支付接口后，返回系统错误或未知交易状态情况； 调用alipay.trade.pay，返回INPROCESS的状态； 调用alipay.trade.cancel之前，需确认支付状态；

/*** 交易查询接口* https://doc.open.alipay.com/docs/api.htm?spm=a219a.7395905.0.0.8H2JzG&docType=4&apiId=757* @param bizContent* @return* @throws AlipayApiException*/public static boolean isTradeQuery(AlipayTradeQueryModel model) throws AlipayApiException{AlipayTradeQueryResponse response = tradeQuery(model);if(response.isSuccess()){return true;}return false;}public static AlipayTradeQueryResponse  tradeQuery(AlipayTradeQueryModel model) throws AlipayApiException{AlipayTradeQueryRequest request = new AlipayTradeQueryRequest();request.setBizModel(model);return alipayClient.execute(request);}

3.3.2 alipay.trade.refund 接口封装

当交易发生之后一段时间内，由于买家或者卖家的原因需要退款时，卖家可以通过退款接口将支付款退还给买家，支付宝将在收到退款请求并且验证成功之后，按照退款规则将支付款按原路退到买家帐号上。 交易超过约定时间(签约时设置的可退款时间)的订单无法进行退款 支付宝退款支持单笔交易分多次退款，多次退款需要提交原支付订单的商户订单号和设置不同的退款单号。一笔退款失败后重新提交，要采用原来的退款单号。总退款金额不能超过用户实际支付金额

/*** 退款* https://doc.open.alipay.com/docs/api.htm?spm=a219a.7395905.0.0.SAyEeI&docType=4&apiId=759* @param content* @return* @throws AlipayApiException*/public static String tradeRefund(AlipayTradeRefundModel model) throws AlipayApiException{AlipayTradeRefundResponse response = tradeRefundToResponse(model);return response.getBody();}public static AlipayTradeRefundResponse tradeRefundToResponse(AlipayTradeRefundModel model) throws AlipayApiException{AlipayTradeRefundRequest request = new AlipayTradeRefundRequest();request.setBizModel(model);return alipayClient.execute(request);}

3.3.3 alipay.trade.fastpay.refund.query接口封装

商户可使用该接口查询自已通过alipay.trade.refund提交的退款请求是否执行成功。 该接口的返回码10000，仅代表本次查询操作成功，不代表退款成功。如果该接口返回了查询数据，则代表退款成功，如果没有查询到则代表未退款成功，可以调用退款接口进行重试。重试时请务必保证退款请求号一致。

/*** 退款查询* https://doc.open.alipay.com/docs/api.htm?spm=a219a.7629065.0.0.KQeTSa&apiId=1049&docType=4* @param model* @return* @throws AlipayApiException*/public static String tradeRefundQuery(AlipayTradeFastpayRefundQueryModel model) throws AlipayApiException{AlipayTradeFastpayRefundQueryResponse response = tradeRefundQueryToResponse(model);return response.getBody();}public static AlipayTradeFastpayRefundQueryResponse tradeRefundQueryToResponse(AlipayTradeFastpayRefundQueryModel model) throws AlipayApiException{AlipayTradeFastpayRefundQueryRequest request = new AlipayTradeFastpayRefundQueryRequest();request.setBizModel(model);return alipayClient.execute(request);}

3.3.4 alipay.trade.pay接口封装

收银员使用扫码设备读取用户手机支付宝“付款码”/声波获取设备(如麦克风)读取用户手机支付宝的声波信息后，将二维码或条码信息/声波信息通过本接口上送至支付宝发起支付。

/*** 条形码支付、声波支付* https://doc.open.alipay.com/docs/api.htm?spm=a219a.7629065.0.0.XVqALk&apiId=850&docType=4* @param notifyUrl * @throws AlipayApiException*/public static String tradePay(AlipayTradePayModel model, String notifyUrl) throws AlipayApiException {AlipayTradePayResponse response = tradePayToResponse(model,notifyUrl);return response.getBody();}public static AlipayTradePayResponse tradePayToResponse(AlipayTradePayModel model, String notifyUrl) throws AlipayApiException{AlipayTradePayRequest request = new AlipayTradePayRequest();request.setBizModel(model);// 填充业务参数request.setNotifyUrl(notifyUrl);return alipayClient.execute(request); // 通过alipayClient调用API，获得对应的response类}

3.3.5 alipay.trade.precreate 接口封装

收银员通过收银台或商户后台调用支付宝接口，生成二维码后，展示给用户，由用户扫描二维码完成订单支付。

/*** 扫码支付* https://doc.open.alipay.com/docs/doc.htm?spm=a219a.7629140.0.0.i0UVZn&treeId=193&articleId=105170&docType=1#s4* @param notifyUrl * @return* @throws AlipayApiException */public static String tradePrecreatePay(AlipayTradePrecreateModel model, String notifyUrl) throws AlipayApiException{AlipayTradePrecreateResponse response = tradePrecreatePayToResponse(model,notifyUrl);return response.getBody();}public static AlipayTradePrecreateResponse tradePrecreatePayToResponse(AlipayTradePrecreateModel model, String notifyUrl) throws AlipayApiException{AlipayTradePrecreateRequest request = new AlipayTradePrecreateRequest();request.setBizModel(model);request.setNotifyUrl(notifyUrl);return alipayClient.execute(request);}

3.3.6 alipay.trade.cancel 接口封装

支付交易返回失败或支付系统超时，调用该接口撤销交易。如果此订单用户支付失败，支付宝系统会将此订单关闭；如果用户支付成功，支付宝系统会将此订单资金退还给用户。 注意：只有发生支付系统超时或者支付结果未知时可调用撤销，其他正常支付的单如需实现相同功能请调用申请退款API。提交支付交易后调用【查询订单API】，没有明确的支付结果再调用【撤销订单API】。

/*** 交易撤销接口* https://doc.open.alipay.com/docs/api.htm?spm=a219a.7395905.0.0.XInh6e&docType=4&apiId=866* @param bizContent* @return* @throws AlipayApiException*/public static boolean isTradeCancel(AlipayTradeCancelModel model) throws AlipayApiException{AlipayTradeCancelResponse response = tradeCancel(model);if(response.isSuccess()){return true;}return false;}public static AlipayTradeCancelResponse tradeCancel(AlipayTradeCancelModel model) throws AlipayApiException{AlipayTradeCancelRequest request = new AlipayTradeCancelRequest();request.setBizModel(model);AlipayTradeCancelResponse response = alipayClient.execute(request);return response;}

3.3.7 alipay.trade.create 接口封装

商户通过该接口进行交易的创建下单

/*** 统一收单交易创建接口* https://doc.open.alipay.com/docs/api.htm?spm=a219a.7629065.0.0.21yRUe&apiId=1046&docType=4* @param model* @param notifyUrl * @return* @throws AlipayApiException*/public static AlipayTradeCreateResponse tradeCreate(AlipayTradeCreateModel model, String notifyUrl) throws AlipayApiException{AlipayTradeCreateRequest request = new AlipayTradeCreateRequest();request.setBizModel(model);request.setNotifyUrl(notifyUrl);return alipayClient.execute(request);}

3.3.8 alipay.trade.close 接口封装

用于交易创建后，用户在一定时间内未进行支付，可调用该接口直接将未付款的交易进行关闭。

/*** 关闭订单* https://doc.open.alipay.com/docs/api.htm?spm=a219a.7629065.0.0.21yRUe&apiId=1058&docType=4* @param model* @return* @throws AlipayApiException*/public static boolean isTradeClose(AlipayTradeCloseModel model) throws AlipayApiException{AlipayTradeCloseResponse response = tradeClose(model);if(response.isSuccess()){return true;}return false;}public static AlipayTradeCloseResponse tradeClose(AlipayTradeCloseModel model) throws AlipayApiException{AlipayTradeCloseRequest request = new AlipayTradeCloseRequest();request.setBizModel(model);return alipayClient.execute(request);}

3.3.9 alipay.trade.order.settle接口封装

用于在线下场景交易支付后，进行结算

/*** 交易结算接口* https://doc.open.alipay.com/docs/api.htm?spm=a219a.7395905.0.0.nl0RS3&docType=4&apiId=1147* @param bizContent* @return* @throws AlipayApiException*/public static boolean isTradeOrderSettle(AlipayTradeOrderSettleModel model) throws AlipayApiException{AlipayTradeOrderSettleResponse  response  = tradeOrderSettle(model);if(response.isSuccess()){return true;}return false;}public static AlipayTradeOrderSettleResponse tradeOrderSettle(AlipayTradeOrderSettleModel model) throws AlipayApiException{AlipayTradeOrderSettleRequest request = new AlipayTradeOrderSettleRequest();request.setBizModel(model);return alipayClient.execute(request);}

3.3.10 alipay.fund.trans.toaccount.transfer接口封装

可以参考 支付宝支付-提现到个人支付宝

3.3.11 alipay.fund.trans.order.query接口封装

可以参考 支付宝支付-提现到个人支付宝

3.3.12 alipay.data.dataservice.bill.downloadurl.query 接口封装

为方便商户快速查账，支持商户通过本接口获取商户离线账单下载地址

/*** 查询对账单下载地址* @param bizContent* @return* @throws AlipayApiException*/public static String billDownloadurlQuery(AlipayDataDataserviceBillDownloadurlQueryModel model) throws AlipayApiException{AlipayDataDataserviceBillDownloadurlQueryResponse response =  billDownloadurlQueryToResponse(model);return response.getBillDownloadUrl();}public static AlipayDataDataserviceBillDownloadurlQueryResponse  billDownloadurlQueryToResponse (AlipayDataDataserviceBillDownloadurlQueryModel model) throws AlipayApiException{AlipayDataDataserviceBillDownloadurlQueryRequest request = new AlipayDataDataserviceBillDownloadurlQueryRequest();request.setBizModel(model);return alipayClient.execute(request);}

4、异步通知封装

将异步通知的参数转化为Map为验签做准备

/*** 将异步通知的参数转化为Map* @param request* @return*/public static Map<String, String> toMap(HttpServletRequest request) {System.out.println(">>>>" + request.getQueryString());Map<String, String> params = new HashMap<String, String>();Map<String, String[]> requestParams = request.getParameterMap();for (Iterator<String> iter = requestParams.keySet().iterator(); iter.hasNext();) {String name = (String) iter.next();String[] values = (String[]) requestParams.get(name);String valueStr = "";for (int i = 0; i < values.length; i++) {valueStr = (i == values.length - 1) ? valueStr + values[i] : valueStr + values[i] + ",";}// 乱码解决，这段代码在出现乱码时使用。// valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8");params.put(name, valueStr);}return params;}

使用AlipaySignature.rsaCheckV1(....)接口进行验证签名

public void notify_url() {try {// 获取支付宝POST过来反馈信息Map<String, String> params = AliPayApi.toMap(getRequest());for (Map.Entry<String, String> entry : params.entrySet()) {System.out.println(entry.getKey() + " = " + entry.getValue());}boolean verify_result = AlipaySignature.rsaCheckV1(params, AliPayApi.ALIPAY_PUBLIC_KEY, AliPayApi.CHARSET,AliPayApi.SIGN_TYPE);if (verify_result) {// 验证成功// TODO 请在这里加上商户的业务逻辑程序代码 异步通知可能出现订单重复通知 需要做去重处理System.out.println("notify_url 验证成功succcess");renderText("success");return;} else {System.out.println("notify_url 验证失败");// TODOrenderText("failure");return;}} catch (AlipayApiException e) {e.printStackTrace();renderText("failure");}}
