netpayclinet.jar
|
根據專案工程的需要放置對應路徑下
|
用於提供數字簽名的方法呼叫
|
|
MerPrk.key
|
可以放置到任意路徑下，但是需要呼叫方法指定檔案位置和名稱
|
商戶簽名私鑰
|
|
PgPubk.key
|
可以放置到任意路徑下，但是需要呼叫方法指定檔案位置和名稱
|
ChinaPay簽名公鑰
|
把jar包放進專案lib裡後直接呼叫方法：
1.建立公/私鑰物件buildKey
chinapay.PrivateKey key=new chinapay.PrivateKey();
chinapay.SecureLink t;
boolean flag;
//buildKey用於建立私/公鑰的物件，用於簽名或者驗證簽名,該方法在類chinapay. PrivateKey中。
//第一個引數：MerId 商戶號，長度為15個位元組的數字串，由ChinaPay分配。
//第二個引數：使用私/公鑰的方式，固定為 0
//第三個引數：私/公鑰的檔案路徑（包含檔名稱）baseDiskPath,
File.separator(不同系統自適應路徑)
String baseDiskPath = request.getSession().getServletContext().getRealPath(File.separator);
flag=key.buildKey(MerId,0,baseDiskPath+File.separator+”chinapaykey”+File.separator+”MerPrK.key”);
if (flag==false)
{
System.out.println(“build key error!”);
}else {
System.out.println(“build key ok!”);
}
2.訂單簽名函式signOrder 該方法在類chinapay. SecureLink中
String MerId, OrdId, TransAmt, CuryId, TransDate, TransType,ChkValue;
// 對訂單的簽名,引數說明見頁面表單
ChkValue= t.signOrder(MerId, OrdId, TransAmt, CuryId, TransDate, TransType) ;
//將訂單資料送往頁面提交
request.setAttribute(“ChkValue”, ChkValue);
request.setAttribute(“TransAmt”, TransAmt);
request.setAttribute(“OrdId”, OrdId);
request.setAttribute(“TransDate”, TransDate);
3.//頁面接收引數並自動提交
//這裡action的內容為提交交易資料的URL地址 http://payment-test.chinapay.com/pay/TransGet為測試地址
<form name=”form1″ action=”https://payment.chinapay.com/pay/TransGet”
METHOD=POST>
//MerId為ChinaPay統一分配給商戶的商戶號，15位長度，必填
<input type=hidden name=”MerId” value=””/>
//商戶提交給ChinaPay的交易訂單號，16位長度，必填
<%String OrdId = (String)request.getAttribute(“OrdId”); %>
<input type=hidden name=”OrdId” value=<%=OrdId %>>
//訂單交易金額，單位為分，12位長度，左補0，必填
<%String TransAmt = (String)request.getAttribute(“TransAmt”); %>
<input type=hidden name=”TransAmt” value=<%=TransAmt %>>
//訂單交易幣種，3位長度，固定為人民幣156， 必填
<input type=hidden name=”CuryId” value=”156″/>
//訂單交易日期，8位長度，必填
<%String TransDate = (String)request.getAttribute(“TransDate”); %>
<input type=hidden name=”TransDate” value=<%=TransDate %>>
//交易型別，4位長度，必填,取值範圍為：“0001”和“0002”， 其中“0001”表示消費交易，“0002”表示退貨交易
<input type=hidden name=”TransType” value=”0001″/>
//支付接入版本號，必填,20040916的版本中，如果商戶為二級商戶，訂單號從第5位到第9位必須和商戶號的第11位到第15位相同
<input type=hidden name=”Version” value=”20040916″/>
//後臺交易接收URL，必填，長度不要超過80個位元組
<% String basePath = request.getScheme()+”://”+request.getServerName();
String BgRetUrl = basePath+”/返回頁面”; %>
<input type=hidden name=”BgRetUrl” value=<%=BgRetUrl %>>
//頁面交易接收URL，長度不要超過80個位元組，必填
<input type=hidden name=”PageRetUrl” value=<%=basePath %>>
//支付閘道器號，可選
<input type=hidden name=”GateId” value=””>
//商戶私有域，長度不要超過60個位元組，可選
<%String Priv1 = (String)request.getAttribute(“Priv1”); %>
<input type=hidden name=”Priv1″ value=<%=Priv1 %>>
//256位元組長的ASCII碼,為此次交易提交關鍵資料的數字簽名，必填
<%String ChkValue = (String)request.getAttribute(“ChkValue”); %>
<input type=hidden name=”ChkValue” value=<%=ChkValue %>>
</form>
<script language=”JavaScript”
type=”text/JavaScript”>
form1.submit();
</script>
4.驗證交易應答函式verifyTransResponse 該方法在類chinapay. SecureLink中
//後臺返回頁驗證
chinapay.PrivateKey key=new chinapay.PrivateKey();
chinapay.SecureLink t;
boolean flag;
boolean flag1;
String MerId, OrdId, TransAmt, CuryId, TransDate, TransType,ChkValue,OrderStatus,Priv1;
String plainData, ChkValue2;
MerId = request.getParameter(“merid”);
OrdId = request.getParameter(“orderno”);
TransAmt = request.getParameter(“amount”);
CuryId = request.getParameter(“currencycode”);
TransDate = request.getParameter(“transdate”);
TransType = request.getParameter(“transtype”);
OrderStatus = request.getParameter(“status”);
ChkValue = request.getParameter(“checkvalue”);
Priv1 = request.getParameter(“Priv1”);
String baseDiskPath = request.getSession().getServletContext().getRealPath(File.separator);
flag=key.buildKey(“999999999999999″,0,baseDiskPath+File.separator+”chinapaykey”+File.separator+”PgPubk.key”);
if (flag==false)
{
//System.out.println(“build key error!”);
}else {
//System.out.println(“build key ok!”);
}
t=new chinapay.SecureLink (key);
flag1=t.verifyTransResponse(MerId,OrdId, TransAmt, CuryId, TransDate, TransType, OrderStatus, ChkValue);
