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 🙏

Test

Usage

TradeInfo(trade_info).encrypt()

將交易資料透過商店 Key 及 IV 進行 AES 加密。

const NewebPay = require('node-newebpay')

let key = '12345678901234567890123456789012'
let iv = '1234567890123456'
let trade_info = {
  MerchantID: 3430112,
  RespondType: 'JSON',
  TimeStamp: 1485232229,
  Version: 1.4,
  MerchantOrderNo: 'S_1485232229', 
  Amt: 40,
  ItemDesc: 'UnitTest'
}
let trade_info_aes = NewebPay(key, iv).TradeInfo(trade_info).encrypt()
console.log(trade_info_aes) //  ff91c8aa01379e4de621a44e5f11f72e4d25bdb1a18242db6cef9ef07d80b0165e476fd1d9acaa53170272c82d122961e1a0700a7427cfa1cf90db7f6d6593bbc93102a4d4b9b66d9974c13c31a7ab4bba1d4e0790f0cbbbd7ad64c6d3c8012a601ceaa808bff70f94a8efa5a4f984b9d41304ffd879612177c622f75f4214fa

TradeInfo(trade_info).decrypt()

將交易資料透過商店 Key 及 IV 進行 AES 解密。

const NewebPay = require('node-newebpay')

let key = '12345678901234567890123456789012'
let iv = '1234567890123456'
let trade_info_aes = 'ff91c8aa01379e4de621a44e5f11f72e4d25bdb1a18242db6cef9ef07d80b0165e476fd1d9acaa53170272c82d122961e1a0700a7427cfa1cf90db7f6d6593bbc93102a4d4b9b66d9974c13c31a7ab4bba1d4e0790f0cbbbd7ad64c6d3c8012a601ceaa808bff70f94a8efa5a4f984b9d41304ffd879612177c622f75f4214fa'
let trade_info = NewebPay(key, iv).TradeInfo(trade_info_aes).decrypt()

console.log(trade_info) // MerchantID=3430112&RespondType=JSON&TimeStamp=1485232229&Version=1.4&MerchantOrderNo=S_1485232229&Amt=40&ItemDesc=UnitTest

TradeInfo(trade_info).TradeSha()

將已 AES 加密的交易資料, 透過商店 Key 及 IV 進行 SHA256 編碼產生檢查碼。

const NewebPay = require('node-newebpay')

let key = '12345678901234567890123456789012'
let iv = '1234567890123456'
let aes = 'ff91c8aa01379e4de621a44e5f11f72e4d25bdb1a18242db6cef9ef07d80b0165e476fd1d9acaa53170272c82d122961e1a0700a7427cfa1cf90db7f6d6593bbc93102a4d4b9b66d9974c13c31a7ab4bba1d4e0790f0cbbbd7ad64c6d3c8012a601ceaa808bff70f94a8efa5a4f984b9d41304ffd879612177c622f75f4214fa'
let trade_sha = NewebPay(key, iv).TradeInfo(aes).TradeSha()
console.log(trade_sha) // EA0A6CC37F40C1EA5692E7CBB8AE097653DF3E91365E6A9CD7E91312413C7BB8

TradeInfo(trade_info).CheckValue(type?)

將交易資料透過 SHA256 編碼產生檢查碼。

這個 function 可接受一個 type 參數來改變交易參數的排列,預設產生的 CheckValue 根據交易狀態查詢 API (https://core.newebpay.com/API/QueryTradeInfo) 所設計的,但是藍新金流付款的 API (https://core.spgateway.com/MPG/mpg_gateway) 在版本 1.2 之前是使用 CheckValue 來作為檢查碼,所以增加 type 來作為 backward compatibility ,目前藍新金流付款 API 版本 1.6 則不再使用 CheckValue 作為檢查碼的用途。

1.3 增加 winning_request type

因為查詢中獎發票 API(https://inv.ezpay.com.tw/Api_winning/request)所使用的 CheckValue 又有不同的排列方式,所以增加 type 來支援這個 API。

const NewebPay = require('node-newebpay')

let key = 'abcdefg'
let iv = '1234567'
let trade_info = {
  MerchantOrderNo: '840f022',
  MerchantID: '1422967',
  Amt: 100
}
let code = NewebPay(key, iv).TradeInfo(trade_info).CheckValue('QueryTradeInfo')

console.log(code) // 379BF1DB8948EE79D8ED77A1EBCB2F57B0FD45D0376B6DA9CF85F539CEF1C127

TradeInfo(payload).PostData()

將交易資料透過商店 Key 及 IV 進行 AES 加密。

其實同 TradeInfo(trade_info).encrypt() 只是幕後授權 API 用 PostData 作為欄位的名稱。

const NewebPay = require('node-newebpay')

let key = '12345678901234567890123456789012'
let iv = '1234567890123456'
let payload = 'abcdefghijklmnop'
let data = NewebPay(key, iv).TradeInfo(payload).PostData()

console.log(data) // b91d3ece42c203729b38ae004e96efb9b64c41eeb074cad7ebafa3973181d233

TradeInfo(payload).CheckCode(type?)

將交易資料透過 SHA256 編碼產生檢查碼。

其實同 TradeInfo(trade_info).CheckValue() 只是幕後授權 API 用 CheckCode 作為欄位的名稱,同時欄位排列不同。

1.3.3 增加 invoice_number type

因為電子發票字軌管理 API(https://inv.ezpay.com.tw/Api_number_management/searchNumber)所使用的 CheckCode 又有不同的排列方式,所以增加 type 來支援這個 API。

1.3.1 增加 winning_request type

因為查詢中獎發票 API(https://inv.ezpay.com.tw/Api_winning/request)所使用的 CheckCode 又有不同的排列方式,所以增加 type 來支援這個 API。

const NewebPay = require('node-newebpay')

let key = 'abcdefg'
let iv = '1234567'
let trade_info = {
  MerchantOrderNo: '840f022',
  MerchantID: '1422967',
  Amt: 100,
  TradeNo: '14061313541640927'
}
let code = NewebPay(key, iv).TradeInfo(trade_info).CheckCode()
console.log(code) // 62C687AF6409E46E79769FAF54F54FE7E75AAE50BAF0767752A5C337670B8EDB
