对接Ping++支付

作者: 小小蒜头 | 来源:发表于2018-12-14 15:19 被阅读29次

聚合支付是Ping++的产品之一，当然，Ping++一直走在与时俱进，开拓创新道路的前沿，它的业务不只局限于聚合支付，还有账户系统、商户系统等等。最近还推出了一个新产品裂变坊(一条分享链接，让老用户带来新用户)，感兴趣的可以去看看。

对接Ping++的支付其实很简单、便捷，官方给出的开发指南、API文档和一些demo可读性都很强。结合Ping++提供的例子，我这里采用SpringMVC架构调试了Ping++的支付宝电脑网站支付。在此之前我有调试过易宝支付，觉得对接流程过于繁复，你们也可以对比一下。

一、建立web工程

我的工程结构

二、配置文件和依赖关系的建立

web.xml

三、需要注册成为Ping++的用户建立应用获取基础配置参数信息如APP_ID、APP_KEY、公私钥等。

还需要获取RSA公钥和私钥，我选择的是2048位加密。获取之后要将公钥放在Ping++平台的商户RSA公钥里面。

我将这些信息放在Const类里，方便调用。

Ping++ 提供了 Live 和 Test 两个模式，Test模式是模拟的支付，Live模式是和渠道交互的真实支付。两个模式均需要设置 App ID ，两个模式的变更可以通过代码中的 Live Key 和 Test Key 的切换。

apikey

Const

public class Const {
    public static String APP_ID = "app_******";
//    public static String APP_KEY = "sk_test_*****";
    public static String APP_KEY = "sk_live_******";
    public static String APP_PRIVATE_KEY = null;
    public static String PINGPP_PUBLIC__KEY = null;

    static {
        try {
            Resource resource = new ClassPathResource("private.pem");
            InputStream in = resource.getInputStream();
            APP_PRIVATE_KEY = IOUtils.toString(in);
            Resource resource1 = new ClassPathResource("public.pem");
            InputStream in1 = resource1.getInputStream();
            PINGPP_PUBLIC__KEY = IOUtils.toString(in1);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

四、创建支付请求，返回charge对象给客户端

ChargeService

 /**
     * 创建支付
     *
     * @param charge
     * @return
     */
    public String createCharge(Charge charge) {
        Pingpp.appId = Const.APP_ID;
        Pingpp.apiKey = Const.APP_KEY;
        Pingpp.privateKey = Const.APP_PRIVATE_KEY;
        Map<String, Object> chargeMap = new HashMap<String, Object>();
        String orderNo = new Date().getTime() + CommonUtil.randomString(7);
        chargeMap.put("order_no", orderNo);// 推荐使用 8-20 位，要求数字或字母，不允许其他字符
        chargeMap.put("channel", charge.getChannel());// 支付使用的第三方支付渠道取值，请参考：https://www.pingxx.com/api#api-c-new
        chargeMap.put("amount", charge.getAmount());//订单总金额, 人民币单位：分（如订单总金额为 1 元，此处请填 100）
        chargeMap.put("client_ip", charge.getClientIp()); // 发起支付请求客户端的 IP 地址，格式为 IPV4，如: 127.0.0.1
        chargeMap.put("currency", "cny");
        chargeMap.put("subject", "一加6T");
        chargeMap.put("body", "一加，不将就");
        chargeMap.put("description","备注");
        Map<String, String> app = new HashMap<String, String>();
        app.put("id", Const.APP_ID);
        chargeMap.put("app", app);

        // extra 取值请查看相应方法说明
        chargeMap.put("extra", channelExtra(charge.getChannel()));

        try {
            //发起交易请求
            charge = Charge.create(chargeMap);
        } catch (APIConnectionException e) {
            e.printStackTrace();
        } catch (ChannelException e) {
            e.printStackTrace();
        } catch (RateLimitException e) {
            e.printStackTrace();
        } catch (AuthenticationException e) {
            e.printStackTrace();
        } catch (APIException e) {
            e.printStackTrace();
        } catch (InvalidRequestException e) {
            e.printStackTrace();
        }

        // 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
        return charge.toString();
    }

ChargeController

package com.pingpp.controller;

import com.pingplusplus.model.Charge;
import com.pingpp.service.ChargeService;
import com.pingpp.utils.IPUtil;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@Controller
@RequestMapping("/charge")
public class ChargeController {

    private ChargeService chargeService = new ChargeService();

    @RequestMapping(value = "/createCharge")
    @ResponseBody
    public String createCharge(HttpServletRequest request, HttpServletResponse response, @RequestBody Charge charge) {
        charge.setClientIp(IPUtil.getIp(request));
        String chargeString = chargeService.createCharge(charge);

        return chargeString;
    }
}

五、前端调起支付控件

 function wap_pay(channel) {
        var amount = $("#amount").val();
        var params = {
            "channel": channel,
            "amount": amount
        };
        $.ajax({
            type: 'POST',
            data: JSON.stringify(params),
            contentType: "application/json;charset=utf-8",
            dataType: 'json',
            traditional: true, //使json格式的字符串不会被转码
            url: '/charge/createCharge',

            success: function (data) {
                pingpp.createPayment(data, function (result, err) {
                // object 需是 Charge/Order/Recharge 的 JSON 字符串
                // 可按需使用 alert 方法弹出 log
                    console.log(result);
                    console.log(err.msg);
                    console.log(err.extra);
                    if (result == "success") {
                        alert("OK")
                        // 只有微信公众号 (wx_pub)、微信小程序（wx_lite）、QQ 公众号 (qpay_pub)、支付宝小程序（alipay_lite）支付成功的结果会在这里返回，其他的支付结果都会跳转到 extra 中对应的 URL
                    } else if (result == "fail") {
                        alert("fail")
                        // Ping++ 对象 object 不正确或者微信公众号/微信小程序/QQ公众号支付失败时会在此处返回
                    } else if (result == "cancel") {
                        alert("cancel")
                        // 微信公众号、微信小程序、QQ 公众号、支付宝小程序支付取消支付
                    }
                });
            },

            error: function (e) {
                alert("error");

                console.log(e)
            }

        });
    }
</script>

我目前就只测试了支付宝电脑网站支付，如果在对接Ping++支付的过程中有什么疑问，欢迎咨询。
