check login status failed

Error message

check login status failed

What it means

CheckLoginStatus navigates the go-rod page to xiaohongshu.com/explore and queries the login-state CSS selector via pp.Has. This error wraps a failure of the Has query itself — a rod/CDP protocol error, page crash, navigation/context timeout, or target closed — as opposed to merely the element being absent. It means the check could not be performed, not that the user is logged out.

Solutions

1. Check the wrapped err for context.DeadlineExceeded / 'target closed' and re-create the page/browser if the target is gone
2. Increase the timeout or verify the ctx passed in has enough budget for navigate + load + 1s sleep + query
3. Confirm the browser process is alive and the rod page still valid before calling; retry the check once after re-navigating
4. Test network access to https://www.xiaohongshu.com/explore from the host

Example fix

// before
exists, _, err := pp.Has(`.main-container .user .link-wrapper .channel`)
if err != nil {
	return false, errors.Wrap(err, "check login status failed")
}
// after
exists, _, err := pp.Has(`.main-container .user .link-wrapper .channel`)
if err != nil {
	if errors.Is(ctx.Err(), context.DeadlineExceeded) {
		return false, errors.Wrap(err, "check login status timed out")
	}
	return false, errors.Wrap(err, "check login status failed")
}

// 调用前确认浏览器与页面仍可用
if page == nil {
	return errors.New("page is nil")
}
if _, err := page.Context(ctx).Timeout(3 * time.Second).Eval(`() => document.readyState`); err != nil {
	return fmt.Errorf("browser page not alive: %w", err)
}

func isTimeoutErr(err error) bool {
	return errors.Is(err, context.DeadlineExceeded) || strings.Contains(err.Error(), "timeout") || strings.Contains(err.Error(), "target closed")
}

loggedIn, err := loginAction.CheckLoginStatus(ctx)
if err != nil {
	if isTimeoutErr(err) {
		// 浏览器/网络抖动：重建页面后重试一次
		page = browser.MustPage("https://www.xiaohongshu.com")
		loggedIn, err = loginAction.CheckLoginStatus(ctx)
	}
	if err != nil {
		return fmt.Errorf("login check failed: %w", err)
	}
}

When it happens

Trigger: Calling CheckLoginStatus when: the passed ctx is already expired or times out within the 30s window; the browser/tab was closed between navigation and query; page navigation failed (MustNavigate panics aside, the DOM query races a crashed renderer); rod's WebSocket connection to the browser dropped.

Common situations: Slow network so explore page load exceeds the 30s Timeout; headless browser killed by OOM; caller cancelled the context; xiaohongshu.com unreachable or returning an error page that breaks the expected DOM query.
