springboot + Thymeleaf 做的 VISA 支付 做个笔记。
在开发中一直想行项目中抽离出来
以下是 大概的流程图
第一步先确定数据的发送
源码是这样的
package com.vb.controller;import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;import com.asiapay.secure.PaydollarSecureUtil;/*** 此類將用於數據封裝提交到VISA* @author **/
@Controller
public class OnliePay {/*** The merchant ID we provide to you 百度翻譯 ----我们提供给你的商人身份证* * 意思就是我們跟銀行申請支付功能，銀行反饋給我們這邊的id，來標識身份*/private static final String merchantId = "88061970";/*** The currency of the payment i.e.* 貨幣的類型* “344” – HKD 港幣“840” – USD 美元“702” – SGD“156” – CNY (RMB) 毛爺爺“392” – JPY 日元“901” – TWD “036” – AUD“978” – EUR“826” – GBP“124” – CAD */private static final String currCode = "344" ;@RequestMapping("/VISARequest")public ModelAndView virtualRequest(HttpServletRequest request,HttpServletResponse reponse) throws Exception{Map<String, String> map = new ConcurrentHashMap<String,String>();String bankId = "258465466";//插入數據庫生成的流水帳號id ，有助於客戶付款成功後返回給我們的唯一標識String amount = "100";//支付銀行100塊錢String payType = "N";//正常付款/*** 必須获取加密的字符，作用餘銀行收錢成功後返回數據時，做校驗，以防安全隱患 里面源码访问secureHashSecret.config文件里面的字符 去生成*/String secureHash = PaydollarSecureUtil.generatePaymentSecureHash(merchantId, bankId, currCode, amount, payType);map.put("amount", amount);map.put("merchantId", merchantId);map.put("secureHash", secureHash);map.put("orderRef", bankId);map.put("remark", "備註隨意");//不超過 Text (200) 字符return new ModelAndView("vbank/submitfFormBank","map",map);}}
接下来就是跳到页面代码
<div style="margin-left: 25%; margin-top: 15%;"><h1>VISA支付demo參數</h1>
<!-- <form name="payFormCcard" method="post" action="https://www.paydollar.com/b2c2/eng/payment/payForm.jsp"> --><form name="payFormCcard" method="post" action="http://192.168.41.58:8088/virtualBank/pay/virtualRequest"><input type="text" name="merchantId" th:value="${map.merchantId}"><br/><input type="text" name="amount" th:value="${map.amount}" ><br/><input type="text" name="orderRef" th:value="${map.orderRef}"><br/><input type="text" name="remark" th:value="${map.remark}"><br/><input type="text" name="secureHash" th:value="${map.secureHash}"><br/><!-- 支付方式 一下可以選 直接定義全部都可以“ALL” – All the available payment method“CC” – Credit Card Payment“PPS” – PayDollar PPS Payment“PAYPAL” – PayPal By PayDollar Payment“CUP” – PayDollar CUP Payment“ALIPAY” – PayDollar ALIPAY Payment --><input type="hidden" name="payMethod" th:value="ALL" ><br/><!-- The payment card type ---》 支付卡类型可選 (“VISA”,“Master”,”Diners”,”JCB”, “AMEX”) 具體可參照文檔--><input type="text" name="pMethod" th:value="VISA" ><br/><!-- 支付貨幣類型 344 HKD 156 RMB --><input type="text" name="currCode" th:value="344" ><br/><!-- 立即付款 ,具體可看文檔--><input type="text" name="payType" th:value="N"><br/><!-- 語言 E,英,C，中文 --><input type="text" name="lang" th:value="E"><br/><!-- 本項目給銀行返回的結果的連接，告知操作人支付成功還是失敗PS: 自定義連接--><input type="text" name="successUrl" value="http://www.yourdomain.com/Success.html"><br/><input type="text" name="failUrl" value="http://www.yourdomain.com/Fail.html"><br/><input type="text" name="cancelUrl" value="http://www.yourdomain.com/Cancel.html"><br/><input type="submit" name="submit" value="提交"></form> </div>
