以前做过c#应用程序支付宝api接口功能,现在转移到Java程序上,代码如何实现呢?
1、从你的网站提交到支付宝:
/**
* 将订单提交支付宝进行网上支付 */ public ActionForward submitAlipayUrl(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { String orderNo = request.getParameter("orderNo");//订单编号 HashMap hm = new HashMap(); hm.put("_input_charset", "utf-8");// 采用相同的编码方式 hm.put("body", "企鹅个性化图书订单,订单号:" + orderNo);// 填写在跳到支付宝页面上显示的付款内容信息 hm.put("notify_url", "http://127.0.0.1:8888/mypenguin/orders.do?method=AlipayNotify");// 客户付款后,支付宝调用的页面 hm.put("out_trade_no", orderNo);// 外部交易号,最好具有唯一性,在获取支付宝发来的付款信息时使用. hm.put("partner", "2088002302055380");// partnerId(合作伙伴ID) //hm.put("agent", "2088002302055380");// partnerId(合作伙伴ID) hm.put("payment_type", "1");// 支付类型 1=商品购买,2=服务购买,... //hm.put("price", "178.00");// 订单金额信息 hm.put("total_fee", "178.00");// 订单金额和信息 //hm.put("quantity", "1");// 订单商品数量,一般都是写1,它是按照整个订单包来计算
hm.put(“return_url”, “http://127.0.0.1:8888/mypenguin/orders.do?method=AlipayReturn”);// 客户付款成功后,显示给客户的页面
hm.put("show_url", "http://127.0.0.1:8888/mypenguin/books.do?method=list&kindId=1");//展示地址,即在支付页面时,商品名称旁边的“详情”的链接地址。 hm.put("seller_email", "monicali_7766@sina.com");// 你的支付宝账户email hm.put("service", "create_direct_pay_by_user");// create_direct_pay_by_user=直接付款,trade_create_by_buyer=担保付款 hm.put("subject", "企鹅个性化图书订单号:" + orderNo);// 填写在跳到支付宝页面上显示的付款标题信息 String payGateway = "https://www.alipay.com/cooperate/gateway.do";// 跳转到支付宝的url头 String securityCode="7nj9sczcnfc4n8366j46mrzsbqjksmzn";//securityCode(安全码); String sign = makeUrl(hm,securityCode,"utf-8",payGateway);//securityCode(安全码); hm.put("sign", sign); hm.put("sign_type", "MD5"); PrintWriter out = response.getWriter(); out.println("<form name=‘alipaysubmit‘ method=‘post‘ action=‘https://www.alipay.com/cooperate/gateway.do?_input_charset=utf-8‘ >"); out.println("<input type=‘hidden‘ name=‘service‘ value=‘" + hm.get("service") + "‘>"); out.println("<input type=‘hidden‘ name=‘partner‘ value=‘" + hm.get("partner") + "‘>"); out.println("<input type=‘hidden‘ name=‘seller_email‘ value=‘" + hm.get("seller_email") + "‘>");
out.println(““);
out.println("<input type=‘hidden‘ name=‘subject‘ value=‘" + hm.get("subject") + "‘>"); out.println("<input type=‘hidden‘ name=‘body‘ value=‘" + hm.get("body") + "‘>"); out.println("<input type=‘hidden‘ name=‘total_fee‘ value=‘" + hm.get("total_fee") + "‘>"); out.println("<input type=‘hidden‘ name=‘show_url‘ value=‘" + hm.get("show_url") + "‘>"); out.println("<input type=‘hidden‘ name=‘return_url‘ value=‘" + hm.get("return_url") + "‘>"); out.println("<input type=‘hidden‘ name=‘notify_url‘ value=‘" + hm.get("notify_url") + "‘>"); out.println("<input type=‘hidden‘ name=‘payment_type‘ value=‘1‘>"); out.println("<input type=‘hidden‘ name=‘sign‘ value=‘" + hm.get("sign") + "‘>"); out.println("<input type=‘hidden‘ name=‘sign_type‘ value=‘" + hm.get("sign_type") + "‘>"); out.println("</form>"); out.println("<script>"); out.println(" document.alipaysubmit.submit()"); out.println("</script>"); return null; }
/**
* 根据传入的参数生成Alipay的支付URL * @param hm 参数值 * @param securityCode 安全码 * @param charset 编码 * @param payGateway 支付宝gateway
*/ public static String makeUrl(HashMap hm,String securityCode,String charSet,String payGateway) throws Exception{ List keys = new ArrayList(hm.keySet()); Collections.sort(keys);//支付宝要求参数必须按字母排序 StringBuffer content = new StringBuffer(); for (int i = 0; i < keys.size(); i++) { content.append((String) keys.get(i)); content.append("="); content.append((String) hm.get((String) keys.get(i))); if (i != keys.size() - 1) { content.append("&"); } } content.append(securityCode); String sign = DataUtil.MD5Encode(content.toString(), charSet); //MD5加密 return sign; }
2、return_url的内容:
/**
* 支付宝支付完成以后,当前窗口会从支付宝的页面跳转回这个页面。该页面称作“返回页”, * 是同步被支付宝服务器所调用,可当作是支付完成后的提示信息页,如“您的某某某订单,多少金额已支付成功”。
*/
public ActionForward AlipayReturn(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { String alipayNotifyURL = "https://www.alipay.com/cooperate/gateway.do?service=notify_verify"; //String alipayNotifyURL = "http://notify.alipay.com/trade/notify_query.do?";//此路径是在上面链接地址无法起作用时替换使用。 alipayNotifyURL = alipayNotifyURL+ "&partner=2088002302055380¬ify_id="+ request.getParameter("notify_id"); // 获取支付宝ATN返回结果,true是正确的订单信息,false 是无效的 String responseTxt = check(alipayNotifyURL); // 获得POST 过来参数设置到新的requestParams中 Map requestParams = request.getParameterMap(); List keys = new ArrayList(requestParams.keySet()); Collections.sort(keys); StringBuffer content = new StringBuffer(); for (int i = 0; i < keys.size(); i++) { String key=(String) keys.get(i); if(!key.equals("")&&!key.equals("sign")&&!key.equals("sign_type")){ content.append((String) keys.get(i)); content.append("="); content.append((String)requestParams.get((String) keys.get(i))); if (i != keys.size() - 1) { content.append("&"); } } } String securityCode="7nj9sczcnfc4n8366j46mrzsbqjksmzn";//securityCode(安全码); content.append(securityCode); String mysign = DataUtil.MD5Encode(content.toString(), "utf-8"); System.out.println("--------------------------content="+content); System.out.println("--------------------------mysign="+mysign); System.out.println("--------------------------sign="+request.getParameter("sign")); if (mysign.equals(request.getParameter("sign")) && responseTxt.equals("true") ){ if (request.getParameter("trade_status").equalsIgnoreCase("TRADE_FINISHED")){ // 可以做重定向,也可以用来虚拟物品发货 } return mapping.findForward("payOK");//交易成功 }else{ return mapping.findForward("payFail");//交易失败 } }
3、notify_url的内容:
/**
* 通知返回URL,仅适用于异步返回处理结果的接口。有些服务是无法立即返回处理结果的,那么需要通过这个URL将处理结果异步返回给合作伙伴
*/
public ActionForward AlipayNotify(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { String alipayNotifyURL = "https://www.alipay.com/cooperate/gateway.do?service=notify_verify"; //String alipayNotifyURL = "http://notify.alipay.com/trade/notify_query.do?";//此路径是在上面链接地址无法起作用时替换使用。 alipayNotifyURL = alipayNotifyURL+ "&partner=2088002302055380¬ify_id="+ request.getParameter("notify_id"); // 获取支付宝ATN返回结果,true是正确的订单信息,false 是无效的 String responseTxt = check(alipayNotifyURL); // 获得POST 过来参数设置到新的requestParams中 Map requestParams = request.getParameterMap(); List keys = new ArrayList(requestParams.keySet()); Collections.sort(keys); StringBuffer content = new StringBuffer(); for (int i = 0; i < keys.size(); i++) { String key=(String) keys.get(i); if(!key.equals("")&&!key.equals("sign")&&!key.equals("sign_type")){ content.append((String) keys.get(i)); content.append("=");
content.append((String)requestParams.get((String) keys.get(i)));
if (i != keys.size() - 1) { content.append("&"); } } } String securityCode="7nj9sczcnfc4n8366j46mrzsbqjksmzn";//securityCode(安全码); content.append(securityCode); String mysign = DataUtil.MD5Encode(content.toString(), "utf-8"); System.out.println("--------------------------content="+content); System.out.println("--------------------------mysign="+mysign); System.out.println("--------------------------sign="+request.getParameter("sign")); if (mysign.equals(request.getParameter("sign")) && responseTxt.equals("true") ){ if (request.getParameter("trade_status").equalsIgnoreCase("TRADE_FINISHED")){ // 可以做重定向,也可以用来虚拟物品发货 } return mapping.findForward("payOK"); }else{ return mapping.findForward("payFail"); } }
/**
@param myUrl
*
String inputLine = ““;
try
{
URL url = new URL(urlvalue);
HttpURLConnection urlConnection = (HttpURLConnection)url.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
String stTemp = ““;
while((stTemp = in.readLine()) != null) { System.out.println(stTemp); inputLine = inputLine + stTemp; }
}
catch(Exception e)
{
e.printStackTrace();
}
return inputLine;
}
代码编写完毕,可以试着debug调试一下
