前言:最近开发支付宝支付功能,总结一下做个分享
官方文档:
支付宝沙箱地址: https://openhome.alipay.com/platform/appdaily.htm?tab=info
支付宝支付流程:
准备工作:获取支付宝沙箱数据(appid,支付宝网关,rsa2秘,沙箱支付账号等)
集成springboot,使用java代码发起支付请求
支付宝收到支付请求后,返回html代码片段,用于前端展示二维码
扫码支付成功后,支付宝发送同步、异步通知请求,同步、异步通知路径可在配置文件中进行配置
收到异步通知结果后,进行验签,验签通过,返回成功信息通知支付宝不在进行异步通知
此时支付宝支付流程完成,调用支付宝查询接口,确认支付成功
一、获取支付宝沙箱数据
打开上述沙箱地址,获取沙箱配置,查看下图信息
二、集成springboot,使用java代码发起支付请求
1、在pom.xml文件添加支付宝依赖
<!-- 支付宝支付 --> <dependency> <groupid>com.alipay.sdk</groupid> <artifactid>alipay-sdk-java</artifactid> <version>3.7.26.all</version> </dependency>
2、在项目中新建一个支付宝工具类
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 = ""; // 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 = ""; // 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 // 这里需要配置支付宝回调的后端路径,必须要外网可以访问 public static string notify_url = "http://localhost:8080/alipay.trade.page.pay-java-utf-8/notify_url.jsp"; // 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 // todo 这里需要配置支付宝回调的前端路径,必须要外网可以访问 public static string return_url = "http://localhost:8080/alipay.trade.page.pay-java-utf-8/return_url.jsp"; // 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"; // 日志路径 public static string log_path = "c:\\"; // ↑↑↑↑↑↑↑↑↑↑请在这里配置您的基本信息↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑ /** * 写日志,方便测试(看网站需求,也可以改成把记录存入数据库) * * @param sword 要写入日志里的文本内容 */ 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(); } } } } }
3、定义service
public interface alipayservice { /** * 发起支付 * @param outtradeno 订单编号(唯一) * @param totalamount 订单价格 * @param subject 商品名称 */ string gopay(string outtradeno,bigdecimal totalamount,string subject) throws exception; /** * 交易查询 * @param outtradeno 订单编号(唯一) */ string query(string outtradeno) throws alipayapiexception; /** * 交易关闭 * @param outtradeno订单编号(唯一) */ string close(string outtradeno) throws alipayapiexception; }
4、实现serviceimpl,发起支付请求,交易查询等
public class alipayserviceimpl implements alipayservice { @autowired private rechargedetailservice rechargedetailservice; @override public string gopay(string outtradeno, bigdecimal totalamount, string subject) throws exception { alipayclient alipayclient = new defaultalipayclient(alipayconfig.gatewayurl, alipayconfig.app_id, alipayconfig.merchant_private_key, "json", alipayconfig.charset, alipayconfig.alipay_public_key, alipayconfig.sign_type); alipaytradepagepayrequest alipayrequest = new alipaytradepagepayrequest(); /** 同步通知,支付完成后,支付成功页面 */ alipayrequest.setreturnurl(alipayconfig.return_url); /** 异步通知,支付完成后,需要进行的异步处理 */ alipayrequest.setnotifyurl(alipayconfig.notify_url); alipayrequest.setbizcontent("{\"out_trade_no\":\"" + outtradeno + "\"," + "\"total_amount\":\"" + totalamount + "\"," + "\"subject\":\"" + subject + "\"," + "\"body\":\"付款\"," + "\"timeout_express\":\"15m\"," + "\"product_code\":\"fast_instant_trade_pay\"}"); /** 转换格式 */ string form = ""; form = alipayclient.pageexecute(alipayrequest).getbody(); return form; } @override public string query(string outtradeno) throws alipayapiexception { alipayclient alipayclient = new defaultalipayclient(alipayconfig.gatewayurl, alipayconfig.app_id, alipayconfig.merchant_private_key, "json", alipayconfig.charset, alipayconfig.alipay_public_key, alipayconfig.sign_type); alipaytradequeryrequest alipayrequest = new alipaytradequeryrequest(); /** 请求接口 */ alipayrequest.setbizcontent("{\"out_trade_no\":\"" + outtradeno + "\"," + "\"trade_no\":\"" + "" + "\"}"); /** 转换格式 */ string result = alipayclient.execute(alipayrequest).getbody(); return result; } @override public string close(string outtradeno) throws alipayapiexception { alipaytradecloserequest alipayrequest = new alipaytradecloserequest(); alipayclient alipayclient = new defaultalipayclient(alipayconfig.gatewayurl, alipayconfig.app_id, alipayconfig.merchant_private_key, "json", alipayconfig.charset, alipayconfig.alipay_public_key, alipayconfig.sign_type); alipayrequest.setbizcontent("{\"out_trade_no\":\"" + outtradeno + "\"," + "\"trade_no\":\"" + "" + "\"}"); string result = alipayclient.execute(alipayrequest).getbody(); return result; } }
5、创建支付宝controller
public class alipaycontroller { @autowired private alipayservice alipayservice; /** * 订单支付 */ @getmapping("gopay") public map<object, object> gopay() throws exception{ /** 模仿数据库,从后台调数据*/ string outtradeno = "202101010001"; bigdecimaltotalamount = new bigdecimal(10000); string subject = "苹果12"; string pay = alipayservice.gopay(outtradeno, totalamount, subject); map<object, object> pays = new hashmap<>(); pays.put("pay", pay); return pays; } /** * 交易查询 */ @postmapping("aipayquery") public result<object> alipayquery() throws exception{ /**调取支付订单号*/ string outtradeno = "13123"; string query = alipayservice.query(outtradeno); object json = jsonobject.tojson(query); /*jsonobject jobject = new jsonobject(); jobject.get(query);*/ return result.success(json); } /** * 交易关闭 * @throws alipayapiexception */ @postmapping("alipayclose") public result<object> alipaycolse() throws alipayapiexception{ /** 调取数据*/ string outtradeno = "13123"; string close = alipayservice.close(outtradeno); return result.success(close); } /** * 异步通知支付结果 * * @param request * @return string * @throws alipayapiexception * @throws parseexception */ @postmapping("/callback") public string alipaynotify(httpservletrequest request) throws exception { // 获取支付宝的请求信息 map<string, string> map = new hashmap<>(); map<string, string[]> requestparams = request.getparametermap(); if(requestparams.isempty()) { return "failure"; } // 将 map<string,string[]> 转为 map<string,string> for (iterator<string> iter = requestparams.keyset().iterator(); iter.hasnext();) { string name = iter.next(); string[] values = requestparams.get(name); string valuestr = ""; for (int i = 0; i < values.length; i++) { valuestr = (i == values.length - 1) ? valuestr + values[i] : valuestr + values[i] + ","; } map.put(name, valuestr); } // 验签 boolean signverified = alipaysignature.rsacheckv1(map, alipayconfig.alipay_public_key, alipayconfig.charset, alipayconfig.sign_type); // 验签通过 if (signverified) { //支付成功后进行操作 } return "failure"; } }
