输入#失败

Error message

输入#失败

What it means

inputTag wraps any failure from humanize.Type when typing the '#' character into the content editor element. The '#' keystroke is required to trigger Xiaohongshu's topic-autocomplete dropdown; if the underlying browser automation typing fails, the error is wrapped as 输入#失败. It means the browser could not reliably send the '#' key to the content <p> element.

Solutions

1. Ensure the publish page and editor are fully loaded before calling inputTags (wait for the content element to be visible/stable).
2. Re-acquire the content element right before typing instead of reusing a cached *rod.Element.
3. Increase the rod/browser CDP timeout or check network stability to the browser endpoint.
4. Retry the tag input once after a short sleep; the UI may have been momentarily busy.

Example fix

// before
tagErr := inputTags(ctx, contentElem, tags)
// after
if err := contentElem.WaitStable(300 * time.Millisecond); err != nil {
    return errors.Wrap(err, "content element not stable")
}
tagErr := inputTags(ctx, contentElem, tags)

if err := contentElem.WaitStable(300 * time.Millisecond); err != nil { return errors.Wrap(err, "编辑器不可用") }

func isTypingErr(err error) bool { return err != nil && strings.Contains(err.Error(), "输入#失败") }

for i := 0; i < 2; i++ {
    if err := inputTag(ctx, contentElem, tag); err == nil { break }
    time.Sleep(500 * time.Millisecond)
}

When it happens

Trigger: Calling inputTags with a tag list when the content element has become stale/detached, the page navigated away, the editor lost focus, or the rod browser connection dropped during humanize.Type of '#'.

Common situations: Slow page load so the editor isn't ready when tags are typed; page re-render replaces the content element mid-typing; browser tab crashed or was closed; network latency to a remote CDP browser exceeding rod's timeouts.
