{}, + app: {} +}; +""" + +# 在 context 创建后注入 +self._context.add_init_script(STEALTH_SCRIPT) +``` + +### Anti-Patterns to Avoid + +- **Anti-pattern 1: 只修改 webdriver 属性** + - 为什么不好：现代检测会检查 Chrome 对象完整性、plugins 数组、WebGL vendor 等 + - 应该：使用 playwright-stealth 的完整 evasion 套件 + +- **Anti-pattern 2: 在 page.goto() 后注入脚本** + - 为什么不好：页面加载时检测脚本已经执行，太晚了 + - 应该：使用 `context.add_init_script()` 或 `page.add_init_script()` 在页面加载前注入 + +- **Anti-pattern 3: 忽略 Chrome 启动参数** + - 为什么不好：`--disable-blink-features=AutomationControlled` 是第一层防护 + - 应该：同时使用 CLI 参数和 init script + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| navigator.webdriver 伪装 | 手写 Object.defineProperty | playwright-stealth | 库使用 Proxy 更隐蔽，绕过 descriptor 检测 | +| Chrome 对象模拟 | 自己拼凑 chrome.runtime 等 | playwright-stealth | 需要模拟 loadTimes、csi 等复杂结构 | +| Plugins 数组伪装 | 手动创建 navigator.plugins | playwright-stealth | 需要生成符合浏览器特征的 MIME types | +| WebGL 指纹 | 修改 getParameter 返回值 | playwright-stealth | 需要模拟真实的 renderer/vendor 字符串 | + +**Key insight:** playwright-stealth 包含 18 个 evasion scripts，覆盖 Chrome 环境的各个方面。自己实现容易遗漏检测点，且需要持续维护对抗新检测手段。 + +## Common Pitfalls + +### Pitfall 1: 40362 错误仍出现 + +**What goes wrong:** 集成 stealth 后仍被知乎检测到 + +**Why it happens:** +1. 没有同时使用 CLI 参数 `--disable-blink-features=AutomationControlled` +2. 只隐藏了 webdriver 但 Chrome 对象不完整 +3. 浏览器缓存了被污染的 profile + +**How to avoid:** +1. 确保 `browser.launch(args=['--disable-blink-features=AutomationControlled'])` +2. 使用完整的 stealth 配置，不只是 navigator_webdriver +3. 清除 Chrome 缓存：`rm -rf ~/.cache/chrome-*`（参考 GitHub js-reverse-mcp 项目） + +**Warning signs:** 页面加载后控制台出现 `navigator.webdriver === true` + +### Pitfall 2: Headless 模式更容易被检测 + +**What goes wrong:** headless=True 时被检测，headless=False 正常 + +**Why it happens:** Headless Chrome 有额外的指纹特征（User-Agent 中的 HeadlessChrome 字符串） + +**How to avoid:** +1. playwright-stealth 会自动将 HeadlessChrome 替换为 Chrome +2. 确保 `navigator_user_agent=True` 选项开启 + +**Warning signs:** User-Agent 包含 "HeadlessChrome" + +### Pitfall 3: Service Worker 干扰 API 拦截 + +**What goes wrong:** 现有代码已使用 `service_workers: "block"`，与 stealth 无冲突 + +**Why it happens:** 这是正确做法，继续保持 + +**How to avoid:** 无需额外处理，现有配置已正确 + +**Warning signs:** API 拦截不生效 + +## Code Examples + +### 示例 1: ZhihuCrawler 集成 Stealth + +```python +# Source: 项目代码改编 +#

true + + # 检查 plugins 数组 + checks['plugins_count'] = page.evaluate('navigator.plugins.length') + # 期望值: > 0 + + return checks +``` + +### 示例 3: playwright-stealth 同步 API + +```python +# Source:

config.py # 现有配置 +├── proxy_pool.py # 现有代理池 +└── models.py # 现有数据模型 +``` + +### Pattern 1: Stealth 集成模式 + +**What:** 在 `_start_browser_with_proxy()` 方法中，创建 context 后立即应用 stealth + +**When to use:** 所有需要访问知乎的场景 + +**Example:** +```python +# Source: playwright-stealth 官方 + 项目现有代码 +from playwright.sync_api import sync_playwright +from playwright_stealth import Stealth + +def

chrome_load_times=True, + ) + stealth.apply_stealth_sync(self._context) + + # 后续代码不变 + if cookie: + self._add_cookies(cookie) + self._page = self._context.new_page() +``` + +### Pattern 2: 最小化 Init

+STEALTH_SCRIPT = """ +// 隐藏 navigator.webdriver +Object.defineProperty(navigator, 'webdriver', { + get: () => undefined +}); + +// 移除 Playwright 特有属性 +delete window.__playwright; +delete window.__pw_manual; +delete window.__PW_inspect; + +// 模拟 Chrome 对象 +window.chrome = { + runtime: {}, + loadTimes: function() {}, + csi: function() {}, + app: {} +}; +""" + +# 在 context 创建后注入 +self._context.add_init_script(STEALTH_SCRIPT) +``` + +### Anti-Patterns to Avoid + +- **Anti-pattern 1: 只修改 webdriver 属性** + - 为什么不好：现代检测会检查 Chrome 对象完整性、plugins 数组、WebGL vendor 等 + - 应该：使用 playwright-stealth 的完整 evasion 套件 + +- **Anti-pattern 2: 在 page.goto() 后注入脚本** + - 为什么不好：页面加载时检测脚本已经执行，太晚了 + - 应该：使用 `context.add_init_script()` 或 `page.add_init_script()` 在页面加载前注入 + +- **Anti-pattern 3: 忽略 Chrome 启动参数** + - 为什么不好：`--disable-blink-features=AutomationControlled` 是第一层防护 + - 应该：同时使用 CLI 参数和 init script + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| navigator.webdriver 伪装 | 手写 Object.defineProperty | playwright-stealth | 库使用 Proxy 更隐蔽，绕过 descriptor 检测 | +| Chrome 对象模拟 | 自己拼凑 chrome.runtime 等 | playwright-stealth | 需要模拟 loadTimes、csi 等复杂结构 | +| Plugins 数组伪装 | 手动创建 navigator.plugins | playwright-stealth | 需要生成符合浏览器特征的 MIME types | +| WebGL 指纹 | 修改 getParameter 返回值 | playwright-stealth | 需要模拟真实的 renderer/vendor 字符串 | + +**Key insight:** playwright-stealth 包含 18 个 evasion scripts，覆盖 Chrome 环境的各个方面。自己实现容易遗漏检测点，且需要持续维护对抗新检测手段。 + +## Common Pitfalls + +### Pitfall 1: 40362 错误仍出现 + +**What goes wrong:** 集成 stealth 后仍被知乎检测到 + +**Why it happens:** +1. 没有同时使用 CLI 参数 `--disable-blink-features=AutomationControlled` +2. 只隐藏了 webdriver 但 Chrome 对象不完整 +3. 浏览器缓存了被污染的 profile + +**How to avoid:** +1. 确保 `browser.launch(args=['--disable-blink-features=AutomationControlled'])` +2. 使用完整的 stealth 配置，不只是 navigator_webdriver +3. 清除 Chrome 缓存：`rm -rf ~/.cache/chrome-*`（参考 GitHub js-reverse-mcp 项目） + +**Warning signs:** 页面加载后控制台出现 `navigator.webdriver === true` + +### Pitfall 2: Headless 模式更容易被检测 + +**What goes wrong:** headless=True 时被检测，headless=False 正常 + +**Why it happens:** Headless Chrome 有额外的指纹特征（User-Agent 中的 HeadlessChrome 字符串） + +**How to avoid:** +1. playwright-stealth 会自动将 HeadlessChrome 替换为 Chrome +2. 确保 `navigator_user_agent=True` 选项开启 + +**Warning signs:** User-Agent 包含 "HeadlessChrome" + +### Pitfall 3: Service Worker 干扰 API 拦截 + +**What goes wrong:** 现有代码已使用 `service_workers: "block"`，与 stealth 无冲突 + +**Why it happens:** 这是正确做法，继续保持 + +**How to avoid:** 无需额外处理，现有配置已正确 + +**Warning signs:** API 拦截不生效 + +## Code Examples + +### 示例 1: ZhihuCrawler 集成 Stealth + +```python +# Source: 项目代码改编 +# kb_workflow/crawler/zhihu_crawler.py + +from

示例 2: 验证 Stealth 是否生效 + +```python +# Source: 测试用例 +def verify_stealth_applied(page) -> dict: + """验证 stealth 脚本是否正确应用""" + checks = {} + + # 检查 navigator.webdriver + checks['webdriver'] =

- 应该：使用 playwright-stealth 的完整 evasion 套件 - -- **Anti-pattern 2: 在 page.goto() 后注入脚本** - - 为什么不好：页面加载时检测脚本已经执行，太晚了 - - 应该：使用 `context.add_init_script()` 或 `page.add_init_script()` 在页面加载前注入 - -- **Anti-pattern 3: 忽略 Chrome 启动参数** - - 为什么不好：`--disable-blink-features=AutomationControlled` 是第一层防护 - - 应该：同时使用 CLI 参数和 init script - -## Don't Hand-Roll - -| Problem | Don't Build | Use Instead | Why | -|---------|-------------|-------------|-----| -| navigator.webdriver 伪装 | 手写 Object.defineProperty | playwright-stealth | 库使用 Proxy 更隐蔽，绕过 descriptor 检测 | -| Chrome 对象模拟 | 自己拼凑 chrome.runtime 等 | playwright-stealth | 需要模拟 loadTimes、csi 等复杂结构 | -| Plugins 数组伪装 | 手动创建 navigator.plugins | playwright-stealth | 需要生成符合浏览器特征的 MIME types | -| WebGL 指纹 | 修改 getParameter 返回值 | playwright-stealth | 需要模拟真实的 renderer/vendor 字符串 | - -**Key insight:** playwright-stealth 包含 18 个 evasion scripts，覆盖 Chrome 环境的各个方面。自己实现容易遗漏检测点，且需要持续维护对抗新检测手段。 - -## Common Pitfalls - -### Pitfall 1: 40362 错误仍出现 - -**What goes wrong:** 集成 stealth 后仍被知乎检测到 - -**Why it happens:** -1. 没有同时使用 CLI 参数 `--disable-blink-features=AutomationControlled` -2. 只隐藏了 webdriver 但 Chrome 对象不完整 -3. 浏览器缓存了被污染的 profile - -**How to avoid:** -1. 确保 `browser.launch(args=['--disable-blink-features=AutomationControlled'])` -2. 使用完整的 stealth 配置，不只是 navigator_webdriver -3. 清除 Chrome 缓存：`rm -rf ~/.cache/chrome-*`（参考 GitHub js-reverse-mcp 项目） - -**Warning signs:** 页面加载后控制台出现 `navigator.webdriver === true` - -### Pitfall 2: Headless 模式更容易被检测 - -**What goes wrong:** headless=True 时被检测，headless=False 正常 - -**Why it happens:** Headless Chrome 有额外的指纹特征（User-Agent 中的 HeadlessChrome 字符串） - -**How to avoid:** -1. playwright-stealth 会自动将 HeadlessChrome 替换为 Chrome -2. 确保 `navigator_user_agent=True` 选项开启 - -**Warning signs:** User-Agent 包含 "HeadlessChrome" - -### Pitfall 3: Service Worker 干扰 API 拦截 - -**What goes wrong:** 现有代码已使用 `service_workers: "block"`，与 stealth 无冲突 - -**Why it happens:** 这是正确做法，继续保持 - -**How to avoid:** 无需额外处理，现有配置已正确 - -**Warning signs:** API 拦截不生效 - -## Code Examples - -### 示例 1: ZhihuCrawler 集成 Stealth -

Browser Fingerprint Inspection - -**Test:** Launch browser with stealth, open DevTools console, evaluate `navigator.webdriver` -**Expected:** Returns `undefined` or `false`, not `true` -**Why human:** Requires launching actual browser and manually inspecting JavaScript properties - -#### 3. Playwright Properties Check - -**Test:** In same browser, check for `window.__playwright`, `window.__pw_manual`, etc. -**Expected:** All return `undefined` -**Why human:** Requires manual browser inspection - -### Gaps Summary - -No gaps found.
