支付宝初步集成(采用struts集成)
调用流程
1.pc端支付原理简介:客户端提交订单后,点击确认付款,支付宝根据用户判断其是否登录,如果没有登录,用户登录,然后跳转到支付支付宝的支付页面,客户确认付款,然后支付宝进行付款的处理,返回处理结果
1.支付测试页面
<body text=#000000 bgColor="#ffffff" leftMargin=0 topMargin=4>
<header class="am-header">
<h1>支付宝电脑网站支付体验入口页</h1>
</header>
<div id="main">
<div id="tabhead" class="tab-head">
<h2 id="tab1" class="selected" name="tab">付 款</h2>
<h2 id="tab2" name="tab">交 易 查 询</h2>
<h2 id="tab3" name="tab">退 款</h2>
<h2 id="tab4" name="tab">退 款 查 询</h2>
<h2 id="tab5" name="tab">交 易 关 闭</h2>
</div>
<form name=alipayment action="${pageContext.request.contextPath }/ali/ali_aliPay" method=post
target="_blank">
<div id="body1" class="show" name="divcontent">
<dl class="content">
<dt>商户订单号 ：</dt>
<dd>
<input id="WIDout_trade_no" name="WIDout_trade_no" />
</dd>
<hr class="one_line">
<dt>订单名称 ：</dt>
<dd>
<input id="WIDsubject" name="WIDsubject" />
</dd>
<hr class="one_line">
<dt>付款金额 ：</dt>
<dd>
<input id="WIDtotal_amount" name="WIDtotal_amount" />
</dd>
<hr class="one_line">
<dt>商品描述：</dt>
<dd>
<input id="WIDbody" name="WIDbody" />
</dd>
<hr class="one_line">
<dt></dt>
<dd id="btn-dd">
<span class="new-btn-login-sp">
<button class="new-btn-login" type="submit"
style="text-align: center;">付 款</button>
</span> <span class="note-help">如果您点击“付款”按钮，即表示您同意该次的执行操作。</span>
</dd>
</dl>
</div>
</form>
</body>
<script language="javascript">
var tabs = document.getElementsByName('tab');
var contents = document.getElementsByName('divcontent');
(function changeTab(tab) {
for(var i = 0, len = tabs.length; i < len; i++) {
tabs[i].onmouseover = showTab;
}
})();
function showTab() {
for(var i = 0, len = tabs.length; i < len; i++) {
if(tabs[i] === this) {
tabs[i].className = 'selected';
contents[i].className = 'show';
} else {
tabs[i].className = '';
contents[i].className = 'tab-content';
}
}
}
function GetDateNow() {
var vNow = new Date();
var sNow = "";
sNow += String(vNow.getFullYear());
sNow += String(vNow.getMonth() + 1);
sNow += String(vNow.getDate());
sNow += String(vNow.getHours());
sNow += String(vNow.getMinutes());
sNow += String(vNow.getSeconds());
sNow += String(vNow.getMilliseconds());
document.getElementById("WIDout_trade_no").value = sNow;
document.getElementById("WIDsubject").value = "测试";
document.getElementById("WIDtotal_amount").value = "0.01";
}
GetDateNow();
</script>
2.创建一个类A读取公共的属性.
例如:
private static ResourceBundle bundle = ResourceBundle.getBundle("pay");
//支付宝分配给开发者的应用ID
protected String app_id;
public String getApp_id() {
app_id = bundle.getString("alipay_app_id");
return app_id;
}
//接口名称
protected String method;
public String getMethod() {
method = bundle.getString("alipay_method");
return method;
}
3.创建一个action, 继承类A,获取我们的前台提交的表单数据,及我们的公共参数,通过alipayClient发送请求给支付宝,支付宝返回对应对的响应结果,我们将对应的响应结果返回给客户端,后台代码需根据具体的需求及阿里的SDK文档编写代码
如下:
/**
*付款请求
* @return
*/
@Action(value="ali_aliPay")
public String aliPay(){
try {
//获得初始化的AlipayClient
AlipayClient alipayClient = new DefaultAlipayClient(gatewayUrl, app_id, merchant_private_key, "json", charset, alipay_public_key, sign_type);
//设置请求参数
AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();
alipayRequest.setReturnUrl(return_url);
alipayRequest.setNotifyUrl(notify_url);
//商户订单号，商户网站订单系统中唯一订单号，必填
String out_trade_no = new String(getRequest().getParameter("WIDout_trade_no").getBytes("ISO-8859-1"),"UTF-8");
//付款金额，必填
String total_amount = new String(getRequest().getParameter("WIDtotal_amount").getBytes("ISO-8859-1"),"UTF-8");
//订单名称，必填
String subject = new String(getRequest().getParameter("WIDsubject").getBytes("ISO-8859-1"),"UTF-8");
//商品描述，可空
String body = new String(getRequest().getParameter("WIDbody").getBytes("ISO-8859-1"),"UTF-8");
alipayRequest.setBizContent("{\"out_trade_no\":\""+ out_trade_no +"\","
+ "\"total_amount\":\""+ total_amount +"\","
+ "\"subject\":\""+ subject +"\","
+ "\"body\":\""+ body +"\","
+ "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
//若想给BizContent增加其他可选请求参数，以增加自定义超时时间参数timeout_express来举例说明
//alipayRequest.setBizContent("{\"out_trade_no\":\""+ out_trade_no +"\","
// + "\"total_amount\":\""+ total_amount +"\","
// + "\"subject\":\""+ subject +"\","
// + "\"body\":\""+ body +"\","
// + "\"timeout_express\":\"10m\","
// + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
//请求参数可查阅【电脑网站支付的API文档-alipay.trade.page.pay-请求参数】章节
//请求
String result = alipayClient.pageExecute(alipayRequest).getBody();
//输出
getResponse().getOutputStream().println(result);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
new RuntimeException("付款出现异常"+System.currentTimeMillis());
}
return NONE;
}
