1. 支付宝支付接口(沙箱实现)
1.1 支付宝沙箱账号获取
官网
此处作者已经申请了一个沙箱账号,申请过程就不再赘述
如下图:
此处可以自行设置账户金额
1.2 下载客户端(目前好像只支持Android)
下载完成后根据官方提供的账号以及密码登录手机端支付宝账号 如图(商家账号):
1.3 代码配置
工具类AlipayConfig
public class AlipayConfig {
//↓↓↓↓↓↓↓↓↓↓请在这里配置您的基本信息↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
// 应用ID,您的APPID,收款账号既是您的APPID对应支付宝账号
public static String app_id = "";
// 商户私钥,您的PKCS8格式RSA2私钥
public static String merchant_private_key = "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";
// 支付宝公钥,查看地址:https://openhome.alipay.com/platform/keyManage.htm 对应APPID下的支付宝公钥。
public static String alipay_public_key = "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAvxznkDcrpbc5HOXFJ6sQUkyKWLegU4CaAhyoi0A2ID4Y70l9eq9PEMPNqmHUIFhLOIRzctgjhgOZLMNXlvs8mNmpXb4pu3BwJ8hTzawCfuQ0QXYQYPj41exHKWIOS0WjKmjvKg0orPgFFOHu0DhC6jIK+8sQTUnEOipLJ1p87XBcc+jPU+unQGSdHVqYgfKmrTOrE/zHh0wF3mC4SG51GsTPbxiUdwCR2x5rzWvaNE6E9CwIDAQAB";
// 服务器异步通知页面路径 需http://格式的完整路径,不能加?id=123这类自定义参数,必须外网可以正常访问
public static String notify_url = "http://localhost:8080/alipay/alipayNotifyNotice.action";
// 页面跳转同步通知页面路径 需http://格式的完整路径,不能加?id=123这类自定义参数,必须外网可以正常访问
public static String return_url = "http://localhost:8080/alipay/alipayReturnNotice.action";
// 签名方式
public static String sign_type = "RSA2";
// 字符编码格式
public static String charset = "utf-8";
// 支付宝网关
public static String gatewayUrl = "https://openapi.alipaydev.com/gateway.do";
// 支付宝网关
public static String log_path = "C:\\";
//↑↑↑↑↑↑↑↑↑↑请在这里配置您的基本信息↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
public static void logResult(String sWord) {
FileWriter writer = null;
try {
writer = new FileWriter(log_path + "alipay_log_" + System.currentTimeMillis()+".txt");
writer.write(sWord);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (writer != null) {
try {
writer.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}
其中的参数获取如下: app_id
商户私钥,以及支付宝公钥获取方法参考官方文档:密钥生成
页面跳转便是支付以后自动跳转的界面
接下来解释编写下单页面:
@RequestMapping(value = "/goAlipay", produces = "text/html; charset=UTF-8")
@ResponseBody
public String goAlipay(String orderId, HttpServletRequest request, HttpServletRequest response) throws Exception {
order = (Order) request.getSession().getAttribute("order");
orderId="FinchII";
//获得初始化的AlipayClient
AlipayClient alipayClient = new DefaultAlipayClient(AlipayConfig.gatewayUrl, AlipayConfig.app_id, AlipayConfig.merchant_private_key, "json", AlipayConfig.charset, AlipayConfig.alipay_public_key, AlipayConfig.sign_type);
//设置请求参数
AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();
alipayRequest.setReturnUrl(AlipayConfig.return_url);
alipayRequest.setNotifyUrl(AlipayConfig.notify_url);
//商户订单号,商户网站订单系统中唯一订单号,必填
String out_trade_no = orderId;
//付款金额,必填
BigDecimal total_amount = order.getTotalPrice();
//订单名称,必填
int subject = order.getOrderId();
//商品描述,可空
String body = "用户订购商品个数:" + order.getLineItems().size();
// 该笔订单允许的最晚付款时间,逾期将关闭交易。取值范围:1m~15d。m-分钟,h-小时,d-天,1c-当天(1c-当天的情况下,无论交易何时创建,都在0点关闭)。 该参数数值不接受小数点, 如 1.5h,可转换为 90m。
String timeout_express = "1c";
alipayRequest.setBizContent("{\"out_trade_no\":\""+ out_trade_no +"\","
+ "\"total_amount\":\""+ total_amount +"\","
+ "\"subject\":\""+ subject +"\","
+ "\"body\":\""+ body +"\","
+ "\"timeout_express\":\""+ timeout_express +"\","
+ "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
//请求
String result = alipayClient.pageExecute(alipayRequest).getBody();
return result;
}
@RequestMapping(value = "/alipayReturnNotice")
public ModelAndView alipayReturnNotice(HttpServletRequest request, HttpServletRequest response) throws Exception {
//获取支付宝GET过来反馈信息
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);
}
boolean signVerified = AlipaySignature.rsaCheckV1(params, AlipayConfig.alipay_public_key, AlipayConfig.charset, AlipayConfig.sign_type); //调用SDK验证签名
ModelAndView mv = new ModelAndView("alipaySuccess");
//——请在这里编写您的程序(以下代码仅作参考)——
if(signVerified) {
//商户订单号
Order order= (Order) request.getSession().getAttribute("order");
BigDecimal out_trade_no = order.getTotalPrice();
//支付宝交易号
String trade_no = new String(request.getParameter("trade_no").getBytes("ISO-8859-1"),"UTF-8");
//付款金额
String total_amount = new String(request.getParameter("total_amount").getBytes("ISO-8859-1"),"UTF-8");
// 修改叮当状态,改为 支付成功,已付款; 同时新增支付流水
mv.addObject("out_trade_no", out_trade_no);
mv.addObject("trade_no", trade_no);
mv.addObject("total_amount", total_amount);
}else {
}
return mv;
}
@RequestMapping(value = "/alipayNotifyNotice")
@ResponseBody
public String alipayNotifyNotice(HttpServletRequest request, HttpServletRequest response) throws Exception {
//获取支付宝POST过来反馈信息
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);
}
boolean signVerified = AlipaySignature.rsaCheckV1(params, AlipayConfig.alipay_public_key, AlipayConfig.charset, AlipayConfig.sign_type); //调用SDK验证签名
//——请在这里编写您的程序(以下代码仅作参考)——
if(signVerified) {//验证成功
//商户订单号
String out_trade_no = new String(request.getParameter("out_trade_no").getBytes("ISO-8859-1"),"UTF-8");
//支付宝交易号
String trade_no = new String(request.getParameter("trade_no").getBytes("ISO-8859-1"),"UTF-8");
//交易状态
String trade_status = new String(request.getParameter("trade_status").getBytes("ISO-8859-1"),"UTF-8");
//付款金额
String total_amount = new String(request.getParameter("total_amount").getBytes("ISO-8859-1"),"UTF-8");
if(trade_status.equals("TRADE_FINISHED")){
//判断该笔订单是否在商户网站中已经做过处理
//如果没有做过处理,根据订单号(out_trade_no)在商户网站的订单系统中查到该笔订单的详细,并执行商户的业务程序
//如果有做过处理,不执行商户的业务程序
//注意: 尚自习的订单没有退款功能, 这个条件判断是进不来的, 所以此处不必写代码
//退款日期超过可退款期限后(如三个月可退款),支付宝系统发送该交易状态通知
}else if (trade_status.equals("TRADE_SUCCESS")){
//判断该笔订单是否在商户网站中已经做过处理
//如果没有做过处理,根据订单号(out_trade_no)在商户网站的订单系统中查到该笔订单的详细,并执行商户的业务程序
//如果有做过处理,不执行商户的业务程序
//注意:
//付款完成后,支付宝系统发送该交易状态通知
// 修改叮当状态,改为 支付成功,已付款; 同时新增支付流水
}
}else {//验证失败
}
return "success";
}
基本就是根据客服下单的信息进行后端数据的获取。
