一、请求charge对象

package com.bra.modules.util.pingplusplus;
import com.bra.common.utils.SystemPath;
import com.pingplusplus.Pingpp;
import org.springframework.stereotype.Service;
import java.io.File;
/**
* Created by Afon on 16/4/26.
*/
@Service
public class PingPlusPlusService {
/**
* Pingpp 管理平台对应的 API Key
*/
private final static String apiKey = "";
/**
* Pingpp 管理平台对应的应用 ID
*/
private final static String appId = "";
/**
* 你生成的私钥路径
*/
private final static String privateKeyFilePath = File.separator+SystemPath.getClassPath()+"res"+ File.separator+"rsa_private_key.pem";
public static String charge(String orderNo,int amount,String subject,String body,String channel,String clientIP){
// 设置 API Key
Pingpp.apiKey = apiKey;
// 设置私钥路径，用于请求签名
Pingpp.privateKeyPath = privateKeyFilePath;
PingPlusCharge charge=new PingPlusCharge(appId);
String chargeString=charge.createCharge(orderNo,amount,subject,body,channel,clientIP);
return chargeString;
}
}

二、生成charge 对象

package com.bra.modules.util.pingplusplus;
import com.pingplusplus.exception.PingppException;
import com.pingplusplus.model.Charge;
import java.util.Calendar;
import java.util.HashMap;
import java.util.Map;
/**
* Created by Afon on 16/4/26.
*/
public class PingPlusCharge {
private String appId;
PingPlusCharge(String appId) {
this.appId = appId;
}
public String createCharge(String orderNo, int amount, String subject, String body, String channel, String clientIP) {
/**
* 或者直接设置私钥内容
Pingpp.privateKey = "-----BEGIN RSA PRIVATE KEY-----\n" +
"... 私钥内容字符串 ...\n" +
"-----END RSA PRIVATE KEY-----\n";
*/
Map<String, Object> chargeMap = new HashMap<String, Object>();
chargeMap.put("amount", amount);
chargeMap.put("currency", "cny");
chargeMap.put("subject", subject);
chargeMap.put("body", body);
chargeMap.put("order_no", orderNo);
chargeMap.put("channel", channel);
Calendar cal = Calendar.getInstance();
cal.add(Calendar.MINUTE, 15);//15分钟失效
long timestamp = cal.getTimeInMillis()/ 1000L;
chargeMap.put("time_expire", timestamp);
chargeMap.put("client_ip", clientIP); // 客户端 ip 地址(ipv4)
Map<String, String> app = new HashMap<String, String>();
app.put("id", appId);
chargeMap.put("app", app);
String chargeString = null;
try {
//发起交易请求
Charge charge = Charge.create(chargeMap);
// 传到客户端请先转成字符串 .toString(), 调该方法，会自动转成正确的 JSON 字符串
chargeString = charge.toString();
} catch (PingppException e) {
e.printStackTrace();
}
return chargeString;
}
}

三、webhook

@RequestMapping(value = "webhooks")
@ResponseBody
public void webhooks ( HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
/*System.out.println("ping++　webhooks");*/
request.setCharacterEncoding("UTF8");
//获取头部所有信息
Enumeration headerNames = request.getHeaderNames();
String signature=null;
while (headerNames.hasMoreElements()) {
String key = (String) headerNames.nextElement();
String value = request.getHeader(key);
if("x-pingplusplus-signature".equals(key)){
signature=value;
}
}
/*System.out.println("signature"+signature);*/
// 获得 http body 内容
StringBuffer eventJson=new StringBuffer();
BufferedReader reader= null;
try {
reader = request.getReader();
do{
eventJson.append(reader.readLine());
}while(reader.read()!=-1);
} catch (IOException e) {
e.printStackTrace();
}
reader.close();
JSONObject event=JSON.parseObject(eventJson.toString());
boolean verifyRS=false;
try {
PublicKey publicKey= WebhooksVerifyService.getPubKey();
/* System.out.println(publicKey);*/
verifyRS=WebhooksVerifyService.verifyData(eventJson.toString(),signature,publicKey);
} catch (Exception e) {
e.printStackTrace();
}
if(verifyRS) {
/*System.out.println("签名验证成功");*/
if ("charge.succeeded".equals(event.get("type"))) {
JSONObject data = JSON.parseObject(event.get("data").toString());
JSONObject object = JSON.parseObject(data.get("object").toString());
String orderId = (String) object.get("order_no");
/*System.out.println("orderId:"+orderId);*/
String channel = (String) object.get("channel");
String payType = null;
int amountFen = (int) object.get("amount");
Double amountYuan = amountFen * 1.0 / 100;//ping++扣款,精确到分，而数据库精确到元
Double weiXinInput = null;
Double aliPayInput = null;
Double bankCardInput = null;
if ("wx".equals(channel)) {
payType = "4";//支付类型(1:储值卡，2:现金,3:银行卡,4:微信,5:支付宝,6:优惠券，7：打白条;8:多方式付款;9:微信个人，10：支付宝（个人）)
weiXinInput = amountYuan;
} else if ("alipay".equals(channel)) {
payType = "5";
aliPayInput = amountYuan;
} else if ("upacp".equals(channel) || "upacp_wap".equals(channel) || "upacp_pc".equals(channel)) {
payType = "3";
bankCardInput = amountYuan;
}
Double couponInput;
ReserveVenueCons order = reserveAppVenueConsService.get(orderId);
if (order != null) {
Double orderPrice = order.getShouldPrice();
couponInput = orderPrice - amountYuan;//订单金额-ping++扣款等于优惠金额
Boolean bool = reserveAppVenueConsService.saveSettlement(order, payType, amountYuan,
0.0, bankCardInput, weiXinInput, aliPayInput, couponInput);
if (bool) {
/* System.out.println("订单结算成功");*/
response.setStatus(200);
//return "订单结算成功";
} else {
/* System.out.println("订单结算失败");*/
//return "订单结算失败";
response.setStatus(500);
}
} else {
/* System.out.println("该订单不存在");*/
//return "该订单不存在";
response.setStatus(500);
}
}
}else{
/*System.out.println("签名验证失败");*/
//return "签名验证失败";
response.setStatus(500);
}
}

四、WebhooksVerifyService

package com.bra.modules.util.pingplusplus;
import com.bra.common.utils.SystemPath;
import org.apache.commons.codec.binary.Base64;
import java.io.*;
import java.security.*;
import java.security.spec.X509EncodedKeySpec;
/**
* Created by sunkai on 15/5/19. webhooks 验证签名示例
*
* 该实例演示如何对 Ping++ webhooks 通知进行验证。
* 验证是为了让开发者确认该通知来自 Ping++ ，防止恶意伪造通知。用户如果有别的验证机制，可以不进行验证签名。
*
* 验证签名需要签名、公钥、验证信息，该实例采用文件存储方式进行演示。
* 实际项目中，需要用户从异步通知的 HTTP header 中读取签名，从 HTTP body 中读取验证信息。公钥的存储方式也需要用户自行设定。
*
* 该实例仅供演示如何验证签名，请务必不要直接 copy 到实际项目中使用。
