# Chrome CDP 干净启动 用于:需要在 macOS 上起 `Google Chrome --remote-debugging-port=PORT`,但 Hermes 背景进程被 Chrome 的噪音日志刷屏,或端口/实例冲突。 ## 结论先行 1. 起长驻 Chrome 时,用 `terminal(background=true)`;不要在前台命令里自己加 `&`。 2. 不要给 Chrome 进程挂 `watch_patterns: ["ERROR"]`。Chrome 常年会输出 benign 噪音: - `ssl_client_socket_impl.cc ... net_error -100` - `Crashpad/settings.dat: No such file or directory` 这会导致 Hermes 持续系统通知,污染会话。 3. 启动前先杀旧的同端口/旧 profile 实例,否则常见:`bind() failed: Address already in use (48)`。 4. 若日志已出现 `DevTools listening on ws://...`,则 CDP 基本已活;即使 `curl http://127.0.0.1:PORT/json/version` 一时为空,也别先被后台 `ERROR` 误导。优先检查是否绑在 IPv6 `::1`。 ## 推荐流程 ### 1) 先清旧实例 ```bash pkill -f '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome --remote-debugging-port=19825' || true pkill -f '/tmp/bb-browser-profile' || true pkill -f '~/.bb-browser/browser/user-data' || true mkdir -p /tmp/bb-browser-clean ``` 按实际 port/profile 改。 ### 2) 背景启动,禁用大部分后台噪音源 ```bash '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome' \ --remote-debugging-port=19825 \ --user-data-dir=/tmp/bb-browser-clean \ --no-first-run \ --no-default-browser-check \ --disable-background-networking \ --disable-background-timer-throttling \ --disable-breakpad \ --disable-component-update \ --disable-domain-reliability \ --disable-features=AutofillServerCommunication,CertificateTransparencyComponentUpdater,OptimizationHints,MediaRouter,Translate,ChromeWhatsNewUI \ --disable-sync \ --metrics-recording-only \ --no-pings \ --password-store=basic \ about:blank ``` 在 Hermes 里应用: - `terminal(background=true, ...)` - `watch_patterns` 最多只挂 `"DevTools listening on"` - 不挂 `"ERROR"` ### 3) 验证 优先顺序: 1. `process(action="poll")` 看日志里是否已有 `DevTools listening on ws://...` 2. 再试: - `curl -s http://127.0.0.1:19825/json/version` - 若空,再试 IPv6:`curl -g -s 'http://[::1]:19825/json/version'` 3. 再看进程: ```bash ps -ef | grep -i '[G]oogle Chrome.*19825' ``` ## 常见误判 ### 1. `ssl_client_socket_impl.cc ... net_error -100` 多为 Chrome 后台联网/证书握手失败。通常不影响你眼前的网页调试,也不代表 CDP 挂了。 ### 2. `Crashpad/settings.dat: No such file or directory` 多为 Google 组件/Crashpad 上报目录缺失。属噪音,不是主流程致命错。 ### 3. `bind() failed: Address already in use (48)` 端口已被旧实例占用。先杀旧实例;若不想清理,换新端口。 ### 4. Hermes 一直弹系统消息 通常是你给 Chrome 后台进程挂了 `watch_patterns: ["ERROR"]`。直接 kill 该 background process,重起时删掉此 watch。 ## 最小排障决策 - 看到 `DevTools listening`:先继续,不要因噪音停手。 - 没看到 `DevTools listening` 且端口空:杀旧实例,重起。 - 已活但通知泛滥:kill 背景 watcher,静默重起。 ## 适用场景 - Hermes 里准备接真实 Chrome/CDP - bb-browser / 自建 Chrome remote-debugging 启动混线 - 会话被 Chrome `ERROR` 噪音淹没时 ## 重要分流:不要误开洁净 profile 若用户明确要“当前正在用的 Chrome / 已登录账号 / 现有指纹”,本技能只能用于排障与验证,不能直接默认起 `--user-data-dir=/tmp/...` 的洁净实例。 先判定目标是否为用户真 profile: 1. 查 `~/Library/Application Support/Google/Chrome/Default/Preferences` - `profile.name` 可确认本地 profile 名 - `account_info[0].full_name` / `email` 可确认已登录账号 2. 查 `~/Library/Application Support/Google/Chrome/Local State` - `devtools.remote_debugging.user-enabled` 可确认是否已允许 remote debugging 3. 若目标是现有登录态: - 优先接管该 `Default` profile 对应的现有 Chrome - 不要先开 `/tmp/bb-browser-clean` 一类新 profile - 若必须重启 Chrome 才能挂 CDP,应先向用户确认会影响当前窗口/会话 经验结论: - 用户说“我只有一个 Chrome,登录了某账号”时,默认目标是 `~/Library/Application Support/Google/Chrome/Default` - 误开洁净 profile 会直接偏离真实登录态,即便 CDP 技术上可用,也不满足任务目标
