網站接入銀聯網上支付(B2B)
1、公鑰還有銀行卡號和密碼等銀聯會提供，私鑰按照銀聯提供的文件申請就可以了，需要說明的是申請的時候要用ie，並且在internet 選項-->安全-->自定義級別中，
將Active X 控制元件和外掛 下的所有禁用都改為啟用，如圖：
2、在銀聯提供的測試網址登陸，如圖：
3、輸入登陸資訊，第一次登陸需要修改密碼，然後重新登陸，選擇機構管理，生成商戶金鑰，如圖：
4、選擇生成的私鑰路徑，儲存後，記得要點提交按鈕，私鑰第二天生效。
5、在src下建立config.properties檔案，裡面存放商戶號、支付閘道器申請、公鑰和私鑰的存放路徑,如：
merid = xxxxxxxxxxxxxxxx
merkeyfilepath = E\:\\key\\XXX
pubkeyfilepath = E\:\\key\\XXX
url = http://XXXXXXXXX
6、申請的servlet：
private static final String MERID = "merid";
private static final String PaymentUrl = "url";
private static final String MERKEYFILEPATH = "merkeyfilepath";
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
String MerKeyPath = null;
String merId = null;
String msg="";
try{
Properties config = Config.getInstance().getProperties();
MerKeyPath = config.getProperty(MERKEYFILEPATH);
merId = config.getProperty(MERID);
}catch (Exception e){
msg="私鑰初始化失敗！";
}
if (msg!="") {
request.setAttribute("errors", msg);
request.getRequestDispatcher(XXXXX).forward(request, response);
return;
}
String ordId="0000000000000001";//訂單號只能提交一次
String transAmt="000000000001";//金額
String curyId="156";//幣種
String transDate="20150601";//日期
String transType="0001";//型別
String version="20070129";//版本
String bgRetUrl="http://XXXXXXXXX";//後臺action
String pageRetUrl="http://xxxxx.jsp";//前臺jsp
String gateId="";
String priv1 = "";
String chkValue = null;
boolean flage= false;
PrivateKey key = new PrivateKey();
try{
flage= key.buildKey(merId, 0, MerKeyPath);
}catch (Exception e){
System.out.print("建立失敗");
}
//簽名
String data=merId+ordId+transAmt+curyId+transDate+transType+priv1;
SecureLink sl = new SecureLink(key);
chkValue = sl.Sign(data);
//將要提交的資料顯示到頁面
Bean cbb=new Bean();
cbb.setMerId(merId);
cbb.setOrdId(ordId);
cbb.setTransAmt(transAmt);
cbb.setCuryId(curyId);
cbb.setTransDate(transDate);
cbb.setTransType(transType);
cbb.setPriv1(priv1);
cbb.setVersion(version);
cbb.setBgRetUrl(bgRetUrl);
cbb.setPageRetUrl(pageRetUrl);
cbb.setGateId(gateId);
cbb.setChkValue(chkValue);
request.setAttribute("cbbInput", cbb);
request.getRequestDispatcher(xxxxxxxx).forward(request, response);
return;
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request,response);
}
7、上面的servlet跳轉到下面的頁面：
<%@ page language="java" import="model.bean.*" pageEncoding="UTF-8"%>
<%@ page import="java.util.*"%>
<jsp:useBean id="cbbInput" scope="request" class="model.Bean" />
<form name="corpor" action="測試提交路徑" method="post">
<input type="hidden" name="MerId" value=“xxxxx”/>
<input type="hidden" name="OrdId" value="xxxx"/>
<input type="hidden" name="TransAmt" value="xxx"/>
<input type="hidden" name="CuryId" value="xxx"/>
<input type="hidden" name="TransDate" value="xxx"/>
<input type="hidden" name="TransType" value="xxx"/>
<input type="hidden" name="Version" value="xxx"/>
<input type="hidden" name="BgRetUrl" value="xxx"/>
<input type="hidden" name="PageRetUrl" value="xxx"/>
<input type="hidden" name="GateId" value="xxxx"/>
<input type="hidden" name="Priv1" value=""/>
<input type="hidden" name="ChkValue" value="xxxx"/>
<input type="submit" name="submit Button" value="提交" class="cmd"/>
</form>
8、點選提交，就會到企業網銀登陸頁面，如圖：
9、輸入卡號和密碼登陸，會提示交易結果，如圖：
10、PageRetUrl為上面的頁面跳轉回網站的頁面，BgRetUrl 為後臺action，用來驗證和儲存資料，servlet如下：
private static final String url = "url";
private static final String MERKEYFILEPATH = "merkeyfilepath";
private static final String PUBKEYFILEPATH = "pubkeyfilepath";
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
/*
獲取伺服器返回資料
*/
String status=request.getParameter("status");
String merId=request.getParameter("merid");
String ordno=request.getParameter("orderno");
String transdate=request.getParameter("transdate");
String amount=request.getParameter("amount");
String currencycode=request.getParameter("currencycode");
String transtype=request.getParameter("transtype");
String checkvalue=request.getParameter("checkvalue");
String gateId=request.getParameter("GateId");
String priv1=request.getParameter("Priv1");
// String s=readReqStr(request);
//此處將上面資料存入資料庫
//驗籤
String PubKeyPath = null;
try {
Properties config = Config.getInstance().getProperties();
PubKeyPath = config.getProperty(PUBKEYFILEPATH);
} catch (Exception e) {
}
chinapay.PrivateKey key=new chinapay.PrivateKey();
chinapay.SecureLink t;
boolean flage=false;
boolean flage1=false;
int int = 0;
try{
flage=key.buildKey("999999999999999",int,PubKeyPath);
}catch (Exception e){
}
if(!flage){
return;
}
t=new chinapay.SecureLink(key);
flage1=t.verifyTransResponse(merId,ordno,amount,currencycode,transdate,transtype,status,checkvalue);
if(!flage1){
System.out.print("驗籤失敗");
// return;
}else{
if(status.equals("1001")){
System.out.print("支付成功");
}else {
System.out.print("支付失敗");
}
}
//告訴銀聯你接收到訊息了，否則銀聯會不停的傳送資訊
resp.getWriter().write(JSON.toJSONString(cpCyberBankRes));
resp.getWriter().flush(); } public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doPost(request,response); }
支付測試程式碼完成！！！！
