提取Feed详情失败: %w

Error message

提取Feed详情失败: %w

What it means

extractFeedDetail wraps any failure from the retried extraction (JS evaluation, retries exhausted) into '提取Feed详情失败: %w'. The caller GetFeedDetailWithConfig receives this aggregated error after 3 failed attempts.

Solutions

  1. Read the wrapped %w cause to determine whether it's access-blocked vs extraction failure
  2. Retry later or with a fresh browser context/session
  3. If persistent, check whether the note is accessible and whether the page structure changed

Example fix

// before
return err // opaque
// after
if errors.Is(err, errors.ErrNoFeedDetail) || strings.Contains(err.Error(), "笔记不可访问") { ... skip ... } else { log root cause via %w unwrap }
Defensive patterns

Strategy: try-catch

Try / catch

detail, err := client.GetFeedDetailWithConfig(ctx, id, cfg)
if err != nil {
    log.Errorf("feed %s: %v", id, err) // %w chain preserves root cause
    if strings.Contains(err.Error(), "笔记不可访问") { return nil }
    return err
}

Prevention

When it happens

Trigger: All 3 retry attempts of the in-page extraction returned '无法获取初始状态数据' or the retry call otherwise failed (page closed, navigation error, browser timeout).

Common situations: Heavy anti-bot environment; note blocked so page never contains state; flaky proxy/network causing rod timeouts on all attempts.
