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 🙏

XHS API signature generator

Readme

xhshow-ts

小红书请求签名生成库的 TypeScript 实现,支持 GET/POST 请求的 x-s 和 x-s-common 签名。

本项目基于 Cloxl/xhshow 的 Python 实现移植而来,感谢原作者的无私奉献!

致谢

特别感谢 Cloxl 开源的 xhshow 项目,本项目的核心算法逻辑均来源于此。

系统要求

  • Node.js 16+
  • TypeScript 5.0+(可选,用于开发)

安装

npm install @ikenxuan/xhshow-ts

或使用其他包管理器:

# yarn
yarn add @ikenxuan/xhshow-ts

# pnpm
pnpm add @ikenxuan/xhshow-ts

快速开始

ESM(推荐)

import { Xhshow } from '@ikenxuan/xhshow-ts'

const client = new Xhshow()

// GET 请求签名
const getSignature = client.signXsGet(
  '/api/sns/web/v1/user_posted',
  'your_a1_cookie_value',
  'xhs-pc-web',
  { num: '30', cursor: '', user_id: '123' }
)

// POST 请求签名
const postSignature = client.signXsPost(
  '/api/sns/web/v1/login',
  'your_a1_cookie_value',
  'xhs-pc-web',
  { username: 'test', password: '123456' }
)

// x-s-common 签名
const xsCommon = client.signXsc({
  a1: 'your_a1_cookie_value',
  web_session: 'your_web_session'
})

// 一次性生成所有请求头
const headers = client.signHeadersGet(
  '/api/sns/web/v1/user_posted',
  { a1: 'your_a1_cookie_value', web_session: '...' },
  'xhs-pc-web',
  { num: '30' }
)
// headers 包含: x-s, x-s-common, x-t, x-b3-traceid, x-xray-traceid, x-mns, xy-direction

XYW 签名格式(数据接口绕过 HTTP 406)

自 2026 年 3 月起,数据获取类接口(如 user_posteduser/otherinfo 等)会以 HTTP 406 拒绝传统的 XYS_ 格式签名,需改用基于 AES-128-CBC 的 XYW_ 格式。通过 signFormat: 'xyw' 启用:

// 直接生成 XYW_ 签名
const xyw = client.signXyw(
  'GET',
  '/api/sns/web/v1/user_posted',
  'your_a1_cookie_value',
  'xhs-pc-web',
  { num: '30', cursor: '' }
)

// 或在请求头中通过 signFormat 启用(第 7 个参数)
const headers = client.signHeadersGet(
  '/api/sns/web/v1/user_posted',
  { a1: 'your_a1_cookie_value', web_session: '...' },
  'xhs-pc-web',
  { num: '30' },
  undefined,   // timestamp
  undefined,   // session
  'xyw'        // signFormat: 'xys'(默认)| 'xyw'
)
// 此时 headers['x-s'] 以 XYW_ 开头

x-rap-param(feed / 搜索 / 发布类接口)

feed、搜索、笔记发布等接口需要额外的 x-rap-param 请求头,通过 xRap: true 启用:

const headers = client.signHeadersPost(
  '/api/sns/web/v1/feed',
  { a1: 'your_a1_cookie_value', web_session: '...' },
  'xhs-pc-web',
  { source_note_id: '...' },
  undefined,   // timestamp
  undefined,   // session
  'xys',       // signFormat
  '你的_user_id', // userId(用于 xy-direction 分片,可选)
  true         // xRap:生成 x-rap-param
)
// headers 额外包含 x-rap-param

生成 Cookie 与辅助参数

// 生成 a1 与 web_id
const a1 = Xhshow.generateA1()          // 52 字符
const webId = Xhshow.generateWebId(a1)  // 32 字符 hex

// 搜索接口参数
const searchId = client.getSearchId()             // base36
const requestId = client.getSearchRequestId()     // "{random}-{timestamp_ms}"

使用会话管理(推荐)

会话管理器可以模拟真实用户在同一页面中的连续操作,生成更真实的签名,提高长期稳定性:

import { Xhshow, SessionManager } from '@ikenxuan/xhshow-ts'

const client = new Xhshow()
const session = new SessionManager()

// 使用会话管理器进行多次请求
const headers1 = client.signHeadersGet(
  '/api/sns/web/v1/user_posted',
  { a1: 'your_a1_cookie_value', web_session: '...' },
  'xhs-pc-web',
  { num: '30' },
  undefined,
  session  // 传入会话管理器
)

// 第二次请求,会话状态会自动更新
const headers2 = client.signHeadersGet(
  '/api/sns/web/v1/user_posted',
  { a1: 'your_a1_cookie_value', web_session: '...' },
  'xhs-pc-web',
  { num: '30', cursor: 'next_page' },
  undefined,
  session  // 使用同一个会话管理器
)

// 会话管理器的工作原理:
// - 无 Session:每次请求生成随机参数,可能被识别为机器人
// - 有 Session:维护固定的页面加载时间戳和单调递增的计数器,模拟真实用户行为

CommonJS

const { Xhshow } = require('@ikenxuan/xhshow-ts')

const client = new Xhshow()

const getSignature = client.signXsGet(
  '/api/sns/web/v1/user_posted',
  'your_a1_cookie_value',
  'xhs-pc-web',
  { num: '30', cursor: '', user_id: '123' }
)
