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 🙏

生成私钥 设置私钥 将上面生成的私钥生成无密码的私钥

Importing

const privatePem = fs.readFileSync('private_key.pem');//该私钥为无密码的私钥
const publicPem = fs.readFileSync('public_key.pem');
const alipayJson = {
    app_id: '',  //应用ID
    notify_url: '',//通知地址
};
const key = {
    privateKey: privatePem,//私钥,格式为buffer
    publicKey: publicPem//公钥, 格式为buffer
}
const pay = require('china-pay')('alipay');
//alipayJson, key 必传
const alipay = new pay(alipayJson, key)

Usage

app支付(getAppParam)

  • app端获取支付需要的参数
let biz_content = {
    out_trade_no: '订单号',
    total_amount: '金额',
    subject: '订单标题',
    body: "商品描述"
}
try{
    //result为移动端需要给支付宝的数据
    let result = await alipay.getAppParam(biz_content)
}catch(err){
    //err
}

回调处理(verifySign)

try{
    //obj 为支付宝返回的body对象里面的内容
    let result = await alipay.verifySign(obj)
    //res.send("success");如果成功
}catch(err){
    //认证失败
}

提现(refundTransfer)

try{
    await alipay.refundTransfer({
        out_biz_no :'12124324234',//提现订单
        payee_account:'130*',//支付宝账号
        amount :'0.01',//提款金额
        payee_real_name :'董佳',//支付宝账号对应的真实姓名
        payer_show_name :'欣享车'//支付人的姓名
    });
}catch(err){
    //失败
}

Importing

const wxpayJson = {
    appid: '',  //邮箱里
    mch_id: '',//邮箱里
    notify_url: //邮箱里
};
const key = {
    key:'',//邮箱里
    pfxPath:''//微信证书提现时使用
}
const pay = require('china-pay')('wxpay');
//alipayJson, key 必传
const wxpay = new pay(wxpayJson, key)

Usage

app统一下单接口(appUnifiedorder)

    let obj = {
        attach: '12313231',//附加数据(有时候必填)
        body: '测试',
        out_trade_no: '12312324143',
        total_fee: "1"//(支付费用(分))
    }
    try{
        //前端需要的数据
        let result = await wxpay.appUnifiedorder(obj);
    }catch(err){
        console.log(err)
    }

扫码支付(webUnifiedorder)

    let obj = {
        attach: '12313231',//附加数据(有时候必填)
        body: '测试',
        out_trade_no: '12312324143',
        total_fee: "1"//(支付费用(分))
    }
    try{
        //支付的url码, 该码可以转为二维码
        let result = await wxpay.webUnifiedorder(obj);
    }catch(err){
        console.log(err)
    }

回调处理(notify)

注: 微信返回的格式是xml格式, 因此先对其进行转换, express可以使用express-xml-bodyparser中间件处理

//obj 里面的 key 可以是数组或者字符串
let obj =  {
     appid: [ 'wx7c73ca24*******' ],
     attach: [ '1231323123' ],
    ......
}
//失败则抛出异常, 
try{
    let result = await wxpay.notify(obj)   
}catch(err){
    //
}

//之后需要给wx返回, 返回的参数为“SUCCESS”
// res.set('Content-Type', 'text/xml');
// res.send("SUCCESS")

提现(transfers)

    obj = {}
    obj.openid = ''
    obj.partner_trade_no = '23234234234'
    obj.desc='test'
    obj.amount = 100;
    try{
        await wxpay.transfers(obj)
    }catch(err){
        //失败抛出异常
    }

银联支付

获取tn

回调处理

Prepare

  • 获取私钥 获取银联以priv.pfx结尾的证书后
const pem = require('pem');
const fs = require('fs');
const pfx = fs.readFileSync("/home/dj/priv.pfx");
pem.readPkcs12(pfx, { p12Password: "password" }, (err, cert) => {
    //cert.key就是私钥
    console.log(cert.key)
});
  • 获取certId
wopenssl = require('wopenssl');
var p12 = wopenssl.pkcs12.extract(__dirname + '/priv.pfx', '761202');
var certs = wopenssl.x509.parseCert(p12.certificate);
//certs里面的Serial就是certId, 但是是16进制的, 然后使用python int("1149699808", 16)将其转换为10进制

x509常用命令

openssl pkcs12 -in input.pfx -out mycerts.crt -nokeys -clcerts 将pfx或p12 生成证书。

openssl pkcs12 -in x.pfx -nocerts -nodes -passin pass:123456 | openssl rsa -out privkey.pem pfx生成rsa 私钥

openssl x509 -inform der -in certificate.cer -pubkey -noout > certificate_publickey.pem cer生成公钥(证书有两种格式, 一种是der, 一种是pem。 der是二进制, 而pem是字符串, 可以使用文本编辑器打开看)

Importing

const key = {
    privateKey:fs.readFileSync('/home/dj/privkey.pem'),
    publicKey:fs.readFileSync('/home/dj/pub.pem')
}
const unionpayJson = {
    merId: "8986101739906**",
    frontUrl: "http://papanda.tk:3100",
    certId: "742461010**"
};

const pay = require('china-pay')('unionpay');
//unionpayJson key 必传
const unionpay = new pay(unionpayJson, key)

Usage

获取tn(getTn)

let obj = {
    orderId :'211323213241234321412',
    txnAmt :'1',//(分)
    orderDesc :'这是一个测试'
}
try{
    //result 为tn 前端用来跟银联交互的数据
    let result = await unionpay.getTn(obj);
}catch(err){
    console.log(err)
}

回调处理(notify)

try{
    //有result则成功
    let result = await unionPay.notify(req.body);
}catch(err){
    
}
//给银联的返回
//res.send('success')
