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);
}
}
