输入标题失败

Error message

输入标题失败

What it means

After finding the title element, submitPublishVideo types the title via humanize.Type (simulated human keystrokes). If that returns an error it is wrapped as "输入标题失败". Typically the element became stale/detached or the context was cancelled mid-typing.

Solutions

1. Re-lookup the element immediately before typing, or wrap typing in a retry that re-finds the element
2. Extend the context deadline to allow for human-paced typing
3. Ensure no overlay/dialog intercepts input — dismiss popups first
4. Validate title length/content before calling

Example fix

// before
if err := humanize.Type(ctx, titleElem, title); err != nil {
    return errors.Wrap(err, "输入标题失败")
}
// after
for i := 0; i < 2; i++ {
    titleElem, err = page.Element("div.d-input input")
    if err == nil && humanize.Type(ctx, titleElem, title) == nil {
        break
    }
}

if visible, err := titleElem.Visible(); err != nil || !visible {
    return errors.New("title input not visible for typing")
}

if err := humanize.Type(ctx, titleElem, title); err != nil {
    titleElem, ferr := page.Element("div.d-input input") // re-find stale element
    if ferr != nil { return ferr }
    if terr := humanize.Type(ctx, titleElem, title); terr != nil {
        return errors.Wrap(terr, "输入标题失败")
    }
}

When it happens

Trigger: humanize.Type(ctx, titleElem, title) fails because the element was removed/re-rendered between lookup and typing, ctx deadline exceeded, or the underlying rod input events error out (element not visible, page navigated).

Common situations: Page re-renders the editor right after element lookup (auto-focus redraw); ctx timeout too short for human-speed typing of a long title; modal (e.g. login prompt) steals focus; empty or oversized title rejected by an inline handler.
