手把手教你光大支付

一、支付流程图

手把手教你光大支付_第1张图片

二、流程分析

1.页面ajax访问后台(servlet或resetful接口),给后台传支付参数

2.后台根据参数组织明文和暗文后,返回给前端ajax

3.前端ajax获取后台组织的明文和暗文,以此作为参数访问支付网关

4.支付成功后,光大会访问设置的回调地址,在回调地址中验签,通过则处理订单,以组织明文和暗文回复光大,支付完成

 

三、代码

1.view层

(1)ajax访问后台资源

function pay(restfulUrl, formdata){
    $.get(
        requestUrl+formdata,
        function(data, status){
            if(data.status == -1) {
                alert(data.msg);
                return;
            }
            else if(data.status == 1)
                //window.open(payUrl);//open形式qq浏览器打不开,href的形式可以打开
                window.location.href = data.msg.payUrl+"?Plain="+data.msg.plain+"&Signature="+data.msg.signature;
        },
        "json"
    );
});

 

 

3.service层(restful)

(1)PayService.java

 

 1 public class PayService {
 2 
 3     /**
 4      * 发送光大支付请求
 5      */
 6     public String pay(Map<String, String> paramMap) throws Exception {
 7         
 8         StringBuilder sb = new StringBuilder("");
 9         String split = "~|~";
10         sb.append("MerchantId="+Config.merchantId+split);            //商户代码
11         sb.append("IdentityType=2"+split);                                //用户标识类型    固定2, 用户ID
12         sb.append("MerCifId="+UUID.randomUUID().toString()+split);        //客户在本系统的唯一标示(客户ID),光大据此来记录用户的银行卡信息
13         sb.append("PayType=01"+split);                                    //支付类型    01 网上支付(固定值)
14         sb.append("MerchantSeqNo="+order_id+split);        //商户订单号
15         sb.append("MerchantDateTime="+new Date()+split);    //商户时间
16         sb.append("TransAmount="+payAmount+split);            //交易金额 单位:元
17         sb.append("TerminalType=0"+split);                                //终端标识类型    0 IMEI,1 MAC,2 UUID(针对IOS系统),3 OTHER
18         sb.append("TerminalId=web"+split);                                //终端号
19         sb.append("MerSecName="+split);                                    //二级商户名,测试必送中文,生产可以空着
20         sb.append("ProductCataLog=57"+split);                            //57:综合服务(固定值)
21         sb.append("MerProduct="+""+split);        //商品名称
22         sb.append("MerchantUrl="callbackUrl+split);            //用于后台通知商户,用servlet响应
23         sb.append("MerchantUrl1="+successUrl+split);            //用于后台通知商户失败或者默认情况下,引导客户回商户页面,用servlet响应
24         //sb.append("UserIp", "127.0.0.1");                    //支付地址,测试时127.0.0.1在微信浏览器中无法打开
25         sb.append("msgExt="+paramMap.get("biztypeName"));    //附加信息
26         
27         String plain = sb.toString();
28         String signature = CebMerchantSignVerify.merchantSignData_ABA(plain); 
29         
30         sb.delete(0, sb.length());        
31         sb.append("{");        
32         sb.append("\"payUrl\":\""+cebPayUrl+"\",");
33         sb.append("\"plain\":\""+plain+"\",");
34         sb.append("\"signature\":\""+signature+"\"");
35         sb.append("}");
36         
37         return new JSONUtil.toJson(CebBean(1, sb.toString(), "test"));
38     }
39 }

 

4.回调处理

(1)CallBack.java

@Path("/payback")
public class CebbackService {
	@Context
	HttpServletRequest req;
	@Context
	HttpServletResponse resp;

	@POST
	@Path("/cebback")
	public String cebBack(@FormParam("Plain") String plain,
			@FormParam("Signature") String signature) {
		try {
			connection = JDBCUtil.getConnection();
			connection.setAutoCommit(false);
			//response.setCharacterEncoding("GBK");	//移动端 get utf-8,pc端 post GBK;
			//验签银行信息
			boolean flag = CebMerchantSignVerify.merchantVerifyPayGate_ABA(signature, plain);
			if(flag){
				//拆分接收到的plain,提取需要的字段响应光大
				String[] datas = plain.split("~\\|~");
				Map<String, String> map = new HashMap<String, String>();
				String [] temp = new String[2];
				for(int i = 0 ; i < datas.length ; i++){
					System.out.println(datas[i]);
					temp = datas[i].split("=");
					if(temp.length == 1)
						map.put(temp[0], "");
					else
						map.put(temp[0], temp[1]);
				}
				map.put("signature", signature);
				
		        //组织响应光大的信息
				StringBuffer sf = new StringBuffer();
				sf.append("merchantId="+map.get("merchantId")+"~|~");	//商户代码 	Char 12
				sf.append("orderId="+map.get("orderId")+"~|~");		//订单号 		Char 30
				sf.append("transDateTime="+map.get("transDateTime")+"~|~");		//交易时间 	Char 14		订单发起的时间
				sf.append("procStatus=1~|~");		//处理状态	Char 1		1: 处理成功
				sf.append("MerchantUrl2="+Config.successUrl+"?orderId="+map.get("orderId"));	//商户URL2	Char 256	商户成功接收支付订单情况下的,商户展示页面
				String plain = sf.toString();
				String signature = CebMerchantSignVerify.merchantSignData_ABA(plain);
		        
		        //resp.reset();
		        PrintWriter out = resp.getWriter();
		        resp.getWriter().print("Plain=" + plain);
		        resp.getWriter().print("\n");
		        resp.getWriter().print("Signature=" + signature);
		        resp.getWriter().flush();
		        resp.getWriter().close();
				return  "光大回调成功!";
			}else{
				return "不是光大回调此方法";
			}
		} catch (Exception e) {
			e.printStackTrace();
			try {
				if(connection != null)
					connection.rollback();
					log(e.getMessage());
			} catch (SQLException e1) {
				e1.printStackTrace();
			}
		} finally{
			JDBCUtil.close(connection);
		}
	}
	
	/**
	 * 成功响应光大后的回调处理(形式)
	 */
	@GET
	@Path("/paysuccess")
	public String cebPaySuccess(){
		try {
			resp.sendRedirect("cebPaySuccess.html?orderId="+req.getParameterMap().get("Plain").get("orderId"));
		} catch (IOException e) {
			e.printStackTrace();
		}
		return "支付成功!";
	}

  

(2)servlet

callback.java

 1 public void service(HttpServletRequest request, HttpServletResponse response)
 2             throws ServletException, IOException {
 3         Connection conn = null;
 4         try {
 5             conn =JDBCUtil.getConn();
 6             conn.setAutoCommit(false);
 7             String plain = request.getParameter("Plain");
 8             String signature = request.getParameter("Signature");
 9             
10             //验签银行信息
11             boolean flag = CebMerchantSignVerify.merchantVerifyPayGate_ABA(signature, plain);
12             if(flag){
13                 //拆分接收到的plain,提取需要的字段响应光大
14                 Map<String, String> map = CebUtil.getParam(plain, "~\\|~");
15                 map.put("signature", signature);
16                 
17                 //组织响应信息
18                 StringBuffer sf = new StringBuffer();
19                 sf.append("merchantId="+map.get("merchantId")+"~|~");                //商户代码     Char 12
20                 sf.append("orderId="+map.get("orderId")+"~|~");                        //订单号         Char 30
21                 sf.append("transDateTime="+map.get("transDateTime")+"~|~");            //交易时间     Char 14        订单发起的时间
22                 sf.append("procStatus=1~|~");                                        //处理状态    Char 1        1: 处理成功
23                 sf.append("MerchantUrl2="+cebSuccessUrl);//商户URL2    Char 256    商户成功接收支付订单情况下的,商户展示页面        用servlet响应
24                 //sf.append("MerchantUrl2="+cebSuccessUrl/restful/callback/cebsuccess");//报错:java.lang.IllegalArgumentException: Illegal character in query    
25                 String plain = sf.toString();
26                 String signature = CebMerchantSignVerify.merchantSignData_ABA(plain);
27                 
28                 //响应光大支付的回调
29                 //response.reset();
30                 PrintWriter out = response.getWriter();
31                 out.print("Plain=" + resPlain);
32                 out.print("\n");
33                 out.print("Signature=" + resSignature);
34                 out.flush();
35                 out.close();
36                 //return; //写或不写,光大支付都能正确收到响应
37             }else{
38                 System.out.println("非光大调用此方法");
39                 return;
40             }
41         } catch (Exception e) {
42             try {
43                 if(conn != null)
44                     conn.rollback();
45             } catch (SQLException e1) {
46                 e1.printStackTrace();
47             }
48             return;
49         } finally{
50             JDBCUtil.closeConn(conn);
51         }
