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 🙏

Web 工具集合:signMD5加密,可按需扩展

Readme

dbb-web-tools

Web 工具集合(TypeScript):x-dy 签名、参数排序与 MD5 签名、AES 加密等。

安装

npm install dbb-web-tools

使用

1. x-dy 签名(signMD5)

适用于 axios 等请求配置,按 x-dy 规范用 HmacSHA256 生成 x-dy-signature,并写入 config.headers['x-dy-signature']

const { signMD5 } = require('dbb-web-tools');

// 在请求拦截器中:先设置 nonce、timestamp,再调 signMD5
config.headers['x-dy-nonce'] = nonce;
config.headers['x-dy-timestamp'] = timestamp;

signMD5(appSecret, config, config.method || 'GET', APP_KEY);
// config.headers['x-dy-signature'] 与 config.headers['x-dy-appkey'] 已写入

参数: signMD5(appSecret, params, method, appKey?)

  • appSecret:密钥(必传)
  • params:请求配置,同 axios config(headers、url、baseURL、params、data)
  • method'GET' | 'POST'(必传)
  • appKey:可选,传入时会设置 params.headers['x-dy-appkey']

2. 参数排序与 MD5 签名(generateSignature)

参数排序后拼 &key=privateKey 做 MD5,返回大写 hex,常用于支付等场景。

const { getSortedParams, getSortedParamsString, generateSignature } = require('dbb-web-tools');

getSortedParams({ b: '2', a: '1', sign: 'x' });           // ['a=1', 'b=2']
getSortedParamsString({ b: '2', a: '1' });              // 'a=1&b=2'
generateSignature({ a: '1', b: '2' }, 'your-private-key'); // MD5 大写 hex

3. AES 加密(encrypt)

CBC、Pkcs7,key/iv 按 UTF8 解析。

const { encrypt } = require('dbb-web-tools');

encrypt('plaintext', 'key16bytes!!!!!!', 'iv16bytes!!!!!!');

TypeScript

import { signMD5, type SignParams, generateSignature, encrypt } from 'dbb-web-tools';

发布到 npm

  1. npmjs.com 注册并登录。
  2. 在项目根目录执行:
    npm login
    npm publish
    • 若包名 dbb-web-tools 已被占用,可在 package.json 中改为作用域包,例如 "name": "@你的用户名/dbb-web-tools",然后执行 npm publish --access public
