无法获取初始状态数据

Error message

无法获取初始状态数据

What it means

extractFeedDetail evaluates an in-page JS snippet to pull the initial-state JSON (window __INITIAL_STATE__). If the evaluation returns an empty string, it throws '无法获取初始状态数据'; the retry wrapper retries 3 times with backoff before giving up.

Solutions

  1. Increase wait/delay before extraction (wait for the state element or network idle)
  2. Verify the session isn't being redirected to a login/CAPTCHA page
  3. Update the JS extraction snippet if xiaohongshu renamed __INITIAL_STATE__
Defensive patterns

Strategy: retry

Try / catch

var detail *FeedDetailResponse
err := retry.Do(
    func() error { var e error; detail, e = client.GetFeedDetailWithConfig(ctx, id, cfg); return e },
    retry.Attempts(3), retry.DelayType(retry.BackOffDelay),
)

Prevention

When it happens

Trigger: Page loaded but __INITIAL_STATE__ is missing/empty — e.g. redirected to a login/verification page, SPA not hydrated yet, or a structurally changed page after a xiaohongshu frontend update.

Common situations: Anti-bot redirect to verify page; slow network where rod captured the DOM before state was injected; xiaohongshu changed the global state variable name.
