Error message

提示：<br/>页面已过期，请刷新后重试~<br/>代码：112

What it means

Baidu Netdisk's OpenAPI file-list endpoint (fetched via base.get with access_token, 网盘直链下载助手.user.js:5938) returned errno 112. Baidu uses errno 112 to mean the session/page identifier has expired, so the script throws this 'page expired, refresh and retry' error. It is a server-reported staleness code surfaced as a user-facing error.

Solutions

  1. Refresh the Baidu Netdisk page to get a fresh page context/token, then retry.
  2. Re-run the script's authorization/token-acquisition flow so a new access_token is stored.
  3. If it recurs quickly, clear the script's stored Baidu value (the script manages `baidu_access_token`) and re-authorize.
  4. Check network/proxy time skew or caching that might replay an old token request.
Defensive patterns

Strategy: retry

Validate before calling

const token = base.getValue("baidu_access_token");
if (!token) { /* trigger re-authorization before calling the API */ }

Type guard

function isBaiduExpired(res) { return res && res.errno === 112; }

Try / catch

try {
  await fetchBaiduDownloadLinks(batch);
} catch (e) {
  if (String(e.message).includes("代码：112")) {
    // prompt user to refresh the Baidu page, then re-acquire token and retry once
  } else throw e;
}

Prevention

When it happens

Trigger: Calling the Baidu download-link batch API while the `access_token`/page context bound to the request has expired — e.g. the access token was obtained long before the request, or the Baidu page state the token was issued against was invalidated server-side.

Common situations: Leaving a Baidu Netdisk tab open for hours then trying to fetch links; the token obtained in one session being reused after Baidu rotated it; server-side session invalidation (logout elsewhere, risk control).
