查找正文输入框失败

Error message

查找正文输入框失败

What it means

This error is returned by getContentElement after it repeatedly failed to find a visible body content input element within the given timeout. It wraps the last error from findContentElement, meaning none of the candidate CSS selectors (role=textbox, .tiptap, .ql-editor) matched a visible element before the deadline. The publish flow cannot continue without the content editor element.

Solutions

1. Increase the timeout passed to getContentElement if the page loads slowly.
2. Verify the publish page actually loaded the editor (check login state, page URL, screenshots).
3. Update contentElemSelectors in xiaohongshu/publish.go if the site DOM changed (inspect the live editor).
4. Check whether the editor lives in an iframe and extend search to iframe pages.

Example fix

// before
elem, err := getContentElement(page, 5*time.Second)
// after
elem, err := getContentElement(page, 30*time.Second) // allow slow editor load

// verify the editor actually rendered before publishing
time.Sleep(3 * time.Second) // or wait for a page-load signal
if has, _, _ := page.Has(`div[role="textbox"][contenteditable="true"]`); !has {
    return errors.New("编辑器未加载，取消发布")
}

func contentEditorVisible(page *rod.Page) bool {
    for _, sel := range []string{
        `div[role="textbox"][contenteditable="true"]`,
        `div.tiptap[contenteditable="true"]`,
        `div.ql-editor`,
    } {
        if has, _, _ := page.Has(sel); has {
            return true
        }
    }
    return false
}

err := publisher.Publish(ctx, opts)
if err != nil && strings.Contains(err.Error(), "查找正文输入框失败") {
    // editor never appeared: reload the publish page and retry once
    page.Reload()
    err = publisher.Publish(ctx, opts)
}

When it happens

Trigger: submitPublish or submitPublishVideo calls getContentElement(page, timeout); every poll of findContentElement either errors on page.Elements or finds no visible element, and the deadline expires — the error wraps the last failure.

Common situations: Publish page not fully loaded or showing a different editor variant; Xiaohongshu updated its editor DOM so selectors no longer match; editor is inside an iframe not being searched; page failed to load due to network/login issues.
