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 🙏

node-wxpay3

(支付文档v2) 普通商户接入文档

前言

本模块集成了大部分微信支付、提现等模块的接口,采用async、await的方式调用,使用者不用在考虑参数加密发送,秘钥发送方式、xml怎么解析、json怎么转成xml等一系列麻烦事。

安装

npm i node-wxpay3 --save

版本介绍

本版本是2.*.*相对于旧版本1.*.*做了大的变更,本插件改用typescript重写,合并了旧的接口方法。支持requireimport两种方法导入。

使用

const WxPay = require('node-wxpay3'); 或者 import WxPay from 'node-wxpay3'

// https://api.mch.weixin.qq.com/pay/unifiedorder
const wxpay = new Wxpay({
  appid: '',
  mch_id: '',
  key: '',
  pfx: fs.readFileSync('./apiclient_cert.p12'),
});
const options = {
    body: '测试',
    out_trade_no: '23214234, 
    total_fee: 1,
    spbill_create_ip: 'ip',
    notify_url: 'https://域名/gateway/boboteacher/student/order/_payReturnss', //自己的接口
    trade_type: 'MWEB',
    scene_info: JSON.stringify({
      h5_info: {
        type: 'Wap',
        wap_url: 'https://域名',
        wap_name: 'bobo',
      },
    }),
    redirect_url: 'https://域名/webpage/api/index.html#/', // 支付成功 返回页面 h5支付需要
  };
  const result = await wxpay.unifiedorder(options);

其他接口如下: 如何使用对照微信支付文档和旧版 |接口名称|介绍 | |--|--| |unifiedorder | 统一下单 | |callback_check | 支付回调验证 | |orderquery | 订单查询 | |closeorder | 关闭订单 | |refund | 申请退款 | |refundquery | 查询退款 | |downloadbill | 下载交易账单 | |downloadfundflow | 下载资金账单 | |report | 交易保障 | |batchquerycomment | 拉取订单评价数据 | |micropay | 付款码支付 | |reverse | 撤销订单(只支持付款码支付的订单才可以撤销,统一下单生成的订单不能撤销) | |authcodetoopenid|付款码查询openid| |publicEncrypt|公钥加密| |sendredpack|发放红包| |sendgroupredpack|发放裂变红包| |gethbinfo|查询红包记录| |sendminiprogramhb|小程序红包| |transfers|企业付款到零钱| |gettransferinfo|查询企业付款到零钱| |pay_bank|企业付款到银行卡API| |query_bank|查询企业付款到银行卡| |getpublickey|获取RSA加密公钥API| |send_coupon|发放代金券| |query_coupon_stock|查询代金券批次| |querycouponsinfo|查询代金券信息|

额外增加的接口:

  1. md5 参数object
wxpay.md5({
 body: '测试',
 out_trade_no: '23214234, 
 })
  1. hmac 参数object 使用同上
  2. xmltojson 参数string xml 转json 暴露给外部调用 使用同上
  3. callback_check 支付回调验证 参数object 返回boolean koa

  // 微信返回的数据是text/xml的数据流格式 
  // 接收数据流并且处理
  ctx.req.setEncoding('utf8');
  ctx.req.on('data', function(chunk) {
      data += chunk;
  });
  // getxml 就是xml形式的数据
  const getxml = await new Promise(function(resolve) {
        ctx.req.on('end', function() {
                resolve(data);
        });
  });

  // 调用wxpay.xmltojson(getxml) 获得的参数就是data
  let data = wxpay.xmltojson(getxml)
  let result = wxpay.callback_check(data)
====》 result = true 则校验成功
ctx.type = 'application/xml';
ctx.body =
            `<xml>
                <return_code><![CDATA[SUCCESS]]></return_code>
                <return_msg><![CDATA[OK]]></return_msg>
            </xml>`;
            return; d
  1. publicEncrypt 公钥加密
wxpay.publicEncrypt(publicKey, data)
