public String payment(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { Properties props = new Properties(); props.load(this.getClass().getClassLoader().getResourceAsStream("payment.properties")); /* * 1. 准备13个参数 */ String p0_Cmd = "Buy";//业务类型，固定值Buy String p1_MerId = props.getProperty("p1_MerId");//商号编码，在易宝的唯一标识 String p2_Order = req.getParameter("oid");//订单编码 String p3_Amt = "0.01";//支付金额 String p4_Cur = "CNY";//交易币种，固定值CNY String p5_Pid = "";//商品名称 String p6_Pcat = "";//商品种类 String p7_Pdesc = "";//商品描述 String p8_Url = props.getProperty("p8_Url");//在支付成功后，易宝会访问这个地址。 String p9_SAF = "";//送货地址 String pa_MP = "";//扩展信息 String pd_FrpId = req.getParameter("yh");//支付通道 String pr_NeedResponse = "1";//应答机制，固定值1 /* * 2. 计算hmac * 需要13个参数 * 需要keyValue * 需要加密算法 */ String keyValue = props.getProperty("keyValue"); String hmac = PaymentUtil.buildHmac(p0_Cmd, p1_MerId, p2_Order, p3_Amt, p4_Cur, p5_Pid, p6_Pcat, p7_Pdesc, p8_Url, p9_SAF, pa_MP, pd_FrpId, pr_NeedResponse, keyValue); /* * 3. 重定向到易宝的支付网关 */ StringBuilder sb = new StringBuilder("https://www.yeepay.com/app-merchant-proxy/node"); sb.append("?").append("p0_Cmd=").append(p0_Cmd); sb.append("&").append("p1_MerId=").append(p1_MerId); sb.append("&").append("p2_Order=").append(p2_Order); sb.append("&").append("p3_Amt=").append(p3_Amt); sb.append("&").append("p4_Cur=").append(p4_Cur); sb.append("&").append("p5_Pid=").append(p5_Pid); sb.append("&").append("p6_Pcat=").append(p6_Pcat); sb.append("&").append("p7_Pdesc=").append(p7_Pdesc); sb.append("&").append("p8_Url=").append(p8_Url); sb.append("&").append("p9_SAF=").append(p9_SAF); sb.append("&").append("pa_MP=").append(pa_MP); sb.append("&").append("pd_FrpId=").append(pd_FrpId); sb.append("&").append("pr_NeedResponse=").append(pr_NeedResponse); sb.append("&").append("hmac=").append(hmac); resp.sendRedirect(sb.toString()); return null;} |
3.回馈方法
当支付成功时，易宝会访问这里
用两种方法访问：
1. 引导用户的浏览器重定向(如果用户关闭了浏览器，就不能访问这里了)
2. 易宝的服务器会使用点对点通讯的方法访问这个方法。（必须回馈success，不然易宝服务器会一直调用这个方法）
