Node.js verification library for coco in app purchase receipts

kk-payment-coco is available via npm

npm install kk-payment-coco

It has no external dependencies other than node itself.

此模块用于快速搭建自己的支付验证服务器，针对触控用户系统的支付平台验证流程。 目前处于测试期，用于实际项目请谨慎。

1、填写自己的coco.json配置文件 ，格式可参考包内的coco.example.json文件 ; 2、使用以下代码进行通知验证：

var conf = require('coco.json');
var COCO = require('kk-payment-coco');
var coco = new COCO(conf);
coco.verifyNotify(
    remoteip,
    reqdata,
    function(text) {
        //todo response to remote server.
    },
    function(result, oinfo) {
        if (result) {
            console.log('receive collect order notify.');
            //todo order info handle...
        } else {
            console.log('receive error order notify.');
        }
    }
);

其中, verifyNotify需要四个参数：
第一个参数为接收到订单通知的远程主机IP地址；
第二次参数为接收到的远程主机发过来的数据，要求是字符串，暂时不支持自行解析为JSON对象；
第三个参数为回调函数，被调用时会传回返回给远程主机的Response数据；
第四个参数为订单完成回调函数，可用于后续的订单处理。
