Error message

提示：<br/>访问令牌已过期，再获取一次吧~<br/>代码：9019

What it means

Baidu's API returned errno 9019, which the script (网盘直链下载助手.user.js:5941) interprets as an expired OAuth access token. It deletes the stored `baidu_access_token` so the next attempt re-authorizes, then throws this error telling the user to obtain a token again. Unlike errno 112, the fix is re-authorization rather than a page refresh.

Solutions

1. Re-run the script's Baidu authorization flow to mint and store a fresh access_token (the script already cleared the old one).
2. Retry the download-link fetch after re-authorization; the token is removed automatically on 9019.
3. If re-auth keeps failing, verify the script's Baidu app key/secret config matches a still-valid OAuth app.
4. Clear userscript storage for the site (GM storage) if a bad token persists despite delValue.

const token = base.getValue("baidu_access_token");
if (!token) { /* run the authorization flow to obtain a fresh access_token first */ }

function isBaiduTokenExpired(res) { return res && res.errno === 9019; }

try {
  await fetchBaiduDownloadLinks(batch);
} catch (e) {
  if (String(e.message).includes("代码：9019")) {
    base.delValue("baidu_access_token");
    await reauthorizeBaidu();      // obtain new token
    return fetchBaiduDownloadLinks(batch); // retry once
  }
  throw e;
}

When it happens

Trigger: Any call to the Baidu download-link API while the cached `baidu_access_token` is invalid/expired/revoked — e.g. token expired after its lifetime, Baidu revoked it, or the stored token was corrupted or issued to a different app key.

Common situations: Using the script days after the last authorization; reauthorizing on another device/browser which invalidates the old token; Baidu risk-control revoking tokens; a stale token left in userscript storage after script/config updates.
