无法点击评论输入框: %w

Error message

无法点击评论输入框: %w

What it means

After finding the comment box, PostComment clicks it via humanize.Click to focus the editor. If the click fails (element detached, intercepted by overlay, page navigating), this wrapped error is returned.

Solutions

1. Retry the whole PostComment operation once after a short delay
2. Ensure the page is fully loaded/idle before calling PostComment (wait for network idle)
3. Re-authenticate if a login modal is intercepting clicks
4. Extend humanize/page timeouts if the environment is slow

Example fix

// before
_ = svc.PostComment(ctx, feedID, content) // no retry
// after
err := svc.PostComment(ctx, feedID, content)
if err != nil { time.Sleep(3 * time.Second); err = svc.PostComment(ctx, feedID, content) }

// 确保页面加载完成再评论
page.MustWaitStable() // 或等待网络空闲，避免元素仍在渲染

var err error
for i := 0; i < 2; i++ {
    if err = svc.PostComment(ctx, feedID, content); err == nil || !strings.Contains(err.Error(), "无法点击") {
        break
    }
    time.Sleep(3 * time.Second)
}

When it happens

Trigger: humanize.Click on the comment input span fails because the page navigated/reloaded, a modal/login popup covers the element, or the element became stale between lookup and click.

Common situations: Slow networks where the page is still hydrating; login-expired popups stealing the click; anti-bot overlays; rapid successive calls reusing a closing page.
