VISA (传款易 paydollar ) 支付

本文主要是介绍VISA (传款易 paydollar ) 支付，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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>
