403错误且重新登录失败

Error message

403错误且重新登录失败: %w

What it means

Returned when a search request hit HTTP 403 (session expired or Cloudflare challenge) and the automatic re-login via reloginUser also failed. The original relogin error is wrapped so the caller sees both that a 403 occurred and why recovery failed.

Solutions

1. Fix the underlying relogin error (see the wrapped %w cause): re-save valid credentials.
2. Check site availability and anti-bot status; retry after it recovers.
3. Manually refresh the user's cookies/session.
4. Enable DebugLog to see which step of relogin failed.

// pre-check stored credentials exist before relying on automatic relogin
if user == nil || user.EncryptedPassword == "" {
    return errors.New("cannot auto-relogin: no stored credentials")
}

results, err := p.Search(keyword)
var ctxErr *fmt.wrapError
if err != nil && strings.Contains(err.Error(), "403") {
    // 403 + failed relogin: back off and verify credentials before retrying
    time.Sleep(retryDelay)
    results, err = p.Search(keyword)
}

When it happens

Trigger: searchWithScraper receives a 403 response; the code checks for 403 and calls p.reloginUser(user); reloginUser returns a non-nil error (decrypt or doLogin failure), producing this wrapped error.

Common situations: Session cookie expired long ago and stored credentials are also stale/invalid; site is down or challenging so both the original request and the re-login fail; encryption key mismatch causing the decrypt step inside relogin to fail.
