Ping++支付的实现

由于项目需要，本人用H5实现了Android版，并成功发布。其中支付是使用的Ping++。
Hbuilder限制支付只能使用支付宝和微信。
但是实际上Ping++支付是直接调用支付宝或微信的，Ping++的作用就是统一了支付请求和回调。所以我们在获得支付申请数据之后，拆分出第三方支付所需要的数据，然后调用第三方支付就可以了。
具体步骤和代码：

1. 从后台获取支付请求数据，数据示例:

   
   payid = 'alipay'  
   var payReq = {  
     "body": "***订单",  
     "subject": "xxxxxxxxx",  
     "object": "charge",  
     "client_ip": "175.13.62.206",  
     "order_no": "xxxxxxxxx",  
     "currency": "cny",  
     "amount": 100,  
     "id": "ch_ xxxxxxxxx",  
     "failure_code": null,  
     "paid": false,  
     "refunded": false,  
     "created": 1467358041,  
     "description": null,  
     "amount_refunded": 0,  
     "livemode": false,  
     "amount_settle": 100,  
     "metadata": {},  
     "time_paid": null,  
     "app": "app_ xxxxxxxxx",  
     "extra": {},  
     "credential": {  
       "alipay": {  
         "orderInfo": "_input_charset=\"utf-8\"&body=\"***订单\"&it_b_pay=\"2016-07-02 15:27:21\"&notify_url=\"https%3A%2F%2Fapi.pingxx.com%2Fnotify%2Fcharges%2Fch_ xxxxxxxxx\"&out_trade_no=\"xxxxxxxxx\"&partner=\"xxxxxxxxx\"&payment_type=\"1\"&seller_id=\"xxxxxxxxx\"&service=\"mobile.securitypay.pay\"&subject=\"*****\"&total_fee=\"1.00\"&sign=\"SEM0T1MwMWV6SFdUTFN5WDlPOWVqTEtH\"&sign_type=\"RSA\""  
       },  
       "object": "credential"  
     },  
     "time_settle": null,  
     "time_expire": 1467444441,  
     "failure_msg": null,  
     "refunds": {  
       "data": [],  
       "has_more": false,  
       "object": "list",  
       "url": "/v1/charges/ch_xxxx/refunds"  
     },  
     "transaction_no": null,  
     "channel": "alipay"  
   }  
   };  

payid = 'wxpay';
var payReq = {
"body": "*",
"subject": "****",
"object": "charge",
"client_ip": "175.13.62.206",
"order_no": "xxxxxxxxx",
"currency": "cny",
"amount": 100,
"id": "ch_xx",
"failure_code": null,
"paid": false,
"refunded": false,
"created": 1467358181,
"description": null,
"amount_refunded": 0,
"livemode": false,
"amount_settle": 100,
"metadata": {},
"time_paid": null,
"app": "app_xxx",
"extra": {},
"credential": {
"wx": {
"sign": "xxxxx",
"appId": "xxxxx",
"timeStamp": "1467358181",
"packageValue": "Sign=WXPay",
"partnerId": "123456",
"nonceStr": "11111111111111",
"prepayId": "xxxxxxxxxxxx"
},
"object": "credential"
},
"time_settle": null,
"time_expire": 1467365381,
"failure_msg": null,
"refunds": {
"data": [],
"has_more": false,
"object": "list",
"url": "/v1/charges/ch_xxxxx/refunds"
},
"transaction_no": null,
"channel": "wx"
}
}

2. 转换请求数据  
//-----支付宝支付  
payid = 'alipay';
```javascript  
var order = payReq.credential['alipay'].orderInfo;

//end-----支付宝支付

//-----微信支付
payid = 'wxpay';

var wxData = payReq.credential['wx'];  
var wxPay = {appid:wxData.appId,  
        noncestr:wxData.nonceStr,  
        'package':wxData.packageValue,  
        partnerid:wxData.partnerId,  
        prepayid:wxData.prepayId,  
        timestamp:wxData.timeStamp,  
        sign:wxData.sign};  
var order = JSON.stringify(wxPay);

//end-----微信支付

1. 调用支付
   callPay(payid, order)

//调用支付  
function callPay(payid, order) {  
    console.log("----- order -----" + JSON.stringify(order));  
    plus.payment.request(pays[payid], order, function(result){  
            console.log("----- 支付成功 -----");  
            mui.toast('支付成功');  
                        //支付成功处理  
            //paySuccess (result);  
                },function(e){  
                    plus.nativeUI.closeWaiting();  
                    console.log("----- 支付失败 -----");  
                    console.log("["+e.code+"]："+e.message);  
                    plus.nativeUI.alert("支付失败",null,"错误码："+e.code);  
            });  
}
