Stealth Scraper

基于 Playwright 的反爬虫网页抓取技能,支持普通模式、隐身模式和批量模式。

Description

强大的网页抓取工具,内置反检测技术,绕过常见反爬虫机制。纯手写反检测代码,不依赖任何第三方 stealth 插件。

核心能力:

  • 🕵️ 隐身模式:隐藏 webdriver 指纹、随机 UA、随机延迟、禁用指纹追踪
  • 📄 普通模式:快速抓取页面内容
  • 📦 批量模式:并发抓取多个 URL,自动限速
  • 🎯 精确提取:CSS 选择器定向抓取
  • 📸 截图 & HTML 保存

Configuration

bins: ["node"]

Setup

首次使用前需要安装依赖:

cd ~/.openclaw/workspace/skills/stealth-scraper
npm install

如果 Chromium 未自动安装,运行:

node scripts/setup.js

Usage

普通模式(快速抓取)

node scripts/scraper-simple.js \x3CURL> [options]

参数:

参数 说明 默认值
--wait \x3Cms> 页面加载后等待时间(毫秒) 2000
--selector \x3Ccss> CSS 选择器,只提取匹配元素的内容 无(提取全部)

示例:

# 基本抓取
node scripts/scraper-simple.js https://example.com

# 等待 5 秒后提取
node scripts/scraper-simple.js https://example.com --wait 5000

# 只提取文章正文
node scripts/scraper-simple.js https://example.com --selector "article.content"

隐身模式(反爬虫)

node scripts/scraper-stealth.js \x3CURL> [options]

参数:

参数 说明 默认值
--wait \x3Cms> 页面加载后等待时间(毫秒) 2000
--selector \x3Ccss> CSS 选择器精确提取
--proxy \x3Curl> 代理服务器地址
--screenshot \x3Cpath> 保存截图到指定路径
--html \x3Cpath> 保存完整 HTML 到指定路径
--cookie \x3Cjson> 自定义 cookie(JSON 格式)
--scroll 自动滚动页面加载懒加载内容 false

示例:

# 隐身抓取
node scripts/scraper-stealth.js https://example.com

# 使用代理 + 截图
node scripts/scraper-stealth.js https://example.com --proxy http://127.0.0.1:7890 --screenshot ./shot.png

# 自动滚动 + 保存 HTML
node scripts/scraper-stealth.js https://example.com --scroll --html ./page.html

# 带 cookie 访问
node scripts/scraper-stealth.js https://example.com --cookie '[{"name":"token","value":"abc123","domain":".example.com"}]'

# 精确提取 + 等待
node scripts/scraper-stealth.js https://example.com --selector "div.main" --wait 5000

批量模式

node scripts/scraper-batch.js [options] \x3CURL1> \x3CURL2> ...
# 或
node scripts/scraper-batch.js --file urls.txt [options]

参数:

参数 说明 默认值
--file \x3Cpath> URL 列表文件(每行一个 URL)
--concurrency \x3Cn> 并发数 3
--stealth 使用隐身模式 false
--wait \x3Cms> 每个页面的等待时间 2000
--selector \x3Ccss> CSS 选择器
--output \x3Cpath> 输出 JSON 文件路径 stdout

示例:

# 批量抓取多个 URL
node scripts/scraper-batch.js https://a.com https://b.com https://c.com

# 从文件读取 URL 列表,隐身模式
node scripts/scraper-batch.js --file urls.txt --stealth --concurrency 2

# 输出到文件
node scripts/scraper-batch.js --file urls.txt --output results.json

Output Format

所有模式输出统一的 JSON 结构:

{
  "success": true,
  "url": "https://example.com",
  "title": "Example Domain",
  "content": "页面文本内容...",
  "links": [{"text": "More info", "href": "https://..."}],
  "images": [{"alt": "Logo", "src": "https://..."}],
  "metadata": {
    "description": "...",
    "keywords": "...",
    "author": "..."
  },
  "elapsedSeconds": 2.35
}

Anti-Detection Features

技术 说明
navigator.webdriver 隐藏 删除 webdriver 属性,伪装为真实浏览器
User-Agent 轮换 10+ 真实 UA,涵盖 Chrome/Safari/Firefox,桌面+移动端
随机延迟 1-3 秒随机等待,模拟人类浏览行为
随机视口 随机分辨率,避免固定窗口指纹
WebGL 指纹防护 注入噪声干扰 WebGL 指纹采集
Canvas 指纹防护 对 Canvas 数据添加微小噪声
插件伪装 伪造 navigator.plugins 数组
语言伪装 伪造 navigator.languages
硬件并发伪装 随机化 navigator.hardwareConcurrency

Notes

  • 纯手写反检测代码,不使用任何第三方 stealth 插件(如 puppeteer-extra-plugin-stealth),避免被反检测系统识别
  • 使用 Playwright 而非 Puppeteer,因为 Playwright 的反检测基础更好
  • 所有反检测代码通过 addInitScript 在页面加载前注入
  • 请遵守目标网站的 robots.txt 和服务条款
安全使用建议
This package appears to be what it says: a Playwright-based stealth scraper. Before installing or running it, consider the following: (1) install in a controlled/sandbox environment (container or VM) because npm install and npx playwright install chromium will download and install packages and a browser binary to disk; (2) review the remainder of the stealth injection code (the SKILL listing was truncated) to ensure there are no unexpected network callbacks or telemetry; (3) be aware that fingerprint-evasion code is sensitive and may violate target sites' terms of service or local law—use responsibly and ethically; (4) verify package sources (npm registry/mirror) and run 'npm audit' if possible; (5) when running batch jobs, avoid providing sensitive credentials via command-line/cookie arguments and monitor outgoing network traffic (proxy usage) to ensure no data exfiltration. If you need higher assurance, request a full untruncated review of scripts/scraper-stealth.js and monitor the first npm install in an isolated environment.
功能分析
Type: OpenClaw Skill Name: anti-bot-scraper Version: 1.0.0 The skill bundle is a legitimate web scraping toolset using Playwright, featuring simple, stealth, and batch processing modes. The 'stealth' functionality in `scripts/scraper-stealth.js` implements standard anti-fingerprinting techniques (spoofing User-Agents, navigator properties, and adding Canvas/WebGL noise) to bypass bot detection on target websites. The code is well-structured, lacks obfuscation, and contains no evidence of data exfiltration, malicious command execution, or prompt injection.
能力评估
Purpose & Capability
Name/description (anti-bot Playwright scraper) match the included files and runtime behavior: scripts implement simple, stealth, and batch scraping, with UA/viewports/fingerprint tweaks and optional proxy/cookie input. There are no unrelated credentials, binaries, or config paths requested.
Instruction Scope
SKILL.md instructs the agent/user to run npm install, optionally run scripts/setup.js which itself may run npm install and npx playwright install chromium, and to execute the provided node scripts. The scripts read URL lists, accept proxy/cookie inputs, and write screenshots/HTML/JSON output to disk — all consistent with scraping functionality. One caveat: the provided stealth injection code (truncated in the package listing) modifies many browser-exposed APIs to evade detection; this is expected for the stated purpose but is also sensitive behavior (fingerprint evasion).
Install Mechanism
No platform install spec is present, but package.json and package-lock.json require npm install and the postinstall runs 'npx playwright install chromium' (plus scripts/setup.js also runs npm and npx). This will download packages and browser binaries (Playwright/Chromium) from registries/mirrors. This is expected for a Playwright-based tool but is a higher-risk install action than an instruction-only skill because it writes binaries to disk and runs lifecycle scripts.
Credentials
The skill requests no environment variables or credentials. Command-line options accept proxy URLs and cookie JSON (user-supplied); that is appropriate for a scraper. There are no hidden env accesses in the visible code. No broad credential access or unrelated env vars are requested.
Persistence & Privilege
Skill flags are default (always: false, user-invocable true) and it does not request permanent agent presence or modify other skills' configs. It does install local dependencies and browser binaries into the user's environment when npm install / npx playwright runs, which is normal for Playwright tools but should be run with user consent.
如何使用
  1. 确保已安装 OpenClaw(本地或 Docker 部署)
  2. 在对话框中输入安装命令:/install anti-bot-scraper
  3. 安装完成后,直接呼叫该 Skill 的名称或使用 /anti-bot-scraper 触发
  4. 根据 Skill 的参数说明提供必要输入,即可获得结构化输出
