Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

快速开始

安装

yarn add coa-wx-pay-isv

直接使用

import { CoaWxPayIsvBin, CoaWxPayIsvService } from 'coa-wx-pay-isv'

// 微信支付配置
const config = {
  appId: 'wx00000000001',
  mchId: '1550000001',
  key: '1125XXXXXXXXXXXXXXXXXXX6E20DE9',
  pfx: Buffer.from('XXXXXXX'),
  notifyPay: 'https://example.com/api/notify/pay',
  notifyRefund: 'https://example.com/api/notify/refund',
}

// 创建BIN实例
const bin = new CoaWxPayIsvBin(config)

// 创建服务
const service = new CoaWxPayIsvService(bin)

// 统一下单
await service.unifiedOrder({
  orderId: 'order000001',
  appWxaId: 'wx000000002',
  subMchId: '1660000001',
  openId: 'openIdxxxxxxx',
  price: 100,
  body: '商品信息',
})

// 根据预支付单号,获得支付参数
await service.getPaymentParams({
  appWxaId: 'wx000000002',
  prepayId: 'prepay00001',
})

// 查询订单
await service.queryOrder({
  orderId: 'order000001',
  appWxaId: 'wx000000002',
  subMchId: '1660000001',
})

// 退款
await service.payRefund({
  refundId: 'refund000001',
  orderId: 'order000001',
  price: 100,
  rawData: {},
})

// 查询退款订单
await service.queryRefund({
  refundId: 'refund000001',
  orderId: 'order000001',
  appWxaId: 'wx000000002',
  subMchId: '1660000001',
})

// 下载日对账单
await service.downloadBill({ date: '20210331' })

错误记录

可以使用自定义 Bin 的方式记录错误信息。

import { CoaWxPayIsvBin, CoaWxPayIsvService } from 'coa-wx-pay-isv'

// 微信支付配置
const config = {
  appId: 'wx00000000001',
  mchId: '1550000001',
  key: '1125XXXXXXXXXXXXXXXXXXX6E20DE9',
  pfx: Buffer.from('XXXXXXX'),
  notifyPay: 'https://example.com/api/notify/pay',
  notifyRefund: 'https://example.com/api/notify/refund',
}

// 创建自定义Bin类
class MyCoaWxPayIsvBin extends CoaWxPayIsvBin {
  protected onRequestError(error: Error, response: Axios.AxiosResponse) {
    console.log('error:', error.toString())
    console.log('data:', response.data)
  }
}

// 自定义Bin实例
const bin = new MyCoaWxPayIsvBin(config)

// 是自定义bin创建服务
const service = new CoaWxPayIsvService(bin)

// 错误调用下载日对账单
await service.downloadBill({ date: '' }) // 此时会触发 onRequestError()
