订单退款（未实现）
例子

const order = {
out_trade_no: '1514027114',
out_refund_no: '1516000270202',
total_fee: 1, // 单位元
refund_fee: 1, // 单位元
refund_desc: '退款测试'
}
const result = await wechat.refund(order) // 此方法返回Promise

// APP/小程序退款
// 如果您需要退款 APP/小程序 的订单，请传入第二个字符串参数APP 或 MINIAPP
const result = await wechat.refund(order, 'APP') // APP订单 此方法返回Promise
const result = await wechat.refund(order, 'MINIAPP') // 小程序订单 此方法返回Promise

文档标识未实现，微信支付的退款没有实现吗？

该错误原因有express不原生支持xml parser，因此需要插件。
对于该错误可如下方式解决：

const xmlparser = require('express-xml-bodyparser');
 app.post('/official_pay/tenpay_callback', xmlparser({trim: false, explicitArray: false}), function(req, res, next) {  
    if (wechat.verify(req.body.xml)) { // 一句话验签，就这么简单
        console.log("微信支付异步验签成功：");
        // 业务逻辑
        res.send(wechat.success()); // 可以调用success或fail方法 返回结果
    } else {
        console.log("微信支付异步验签失败：");
        res.send(wechat.fail("验签失败"));
    }
 }

您好。支付宝支付返回exception

微信支付total_fee传人9.8
转换成分变成980.0000000000001
支付失败
需要取整

Nice package!
Could you please add a type definition index.d.ts in this package?

See:
https://www.typescriptlang.org/docs/handbook/declaration-files/dts-from-js.html

cn-pay/src/wechat/index.js line 96
params.total_fee *= 100;变成19.89.999999999浮点数

真香~~~~

如果在统一下单里attach未填，在查询订单返回的数据里attach为空，导致验签失败
微信文档说明：如果参数的值为空不参与签名
