Zhihu risk control blocked answer ${target.answerId} (40362)

Error message

Zhihu risk control blocked answer ${target.answerId} (40362): ${data.errorMessage || 'abnormal request'}

What it means

Zhihu's anti-scraping risk control rejected the request to fetch an answer, returning errorCode 40362 ('abnormal request'). The Zhihu CLI's extractAnswer (via the Browser Bridge) detects this code and throws a CommandExecutionError instead of returning partial data. It signals Zhihu flagged the traffic or session as suspicious, not a bug in the CLI.

Solutions

1. Open the target answer URL in the connected Chrome profile manually to prove the session is human, then retry the download later
2. Log into www.zhihu.com in the connected Chrome profile so requests carry authenticated cookies
3. Reduce request rate: add delays between answer downloads and lower batch size
4. Wait and retry — 40362 blocks are often temporary (minutes to hours)
5. If it persists, switch IP / network or use a different Chrome profile

Example fix

// before: immediate retry loop on failure
await downloadAnswer(id);
// after: back off and verify session first
if (err instanceof CommandExecutionError && err.message.includes('40362')) {
  console.error('Open the answer in Chrome, log in, wait, then retry.');
  await sleep(60_000);
  await downloadAnswer(id);
}

if (!target.answerId || typeof target.answerId !== 'string') throw new Error('Need a valid Zhihu answerId before download');
const answerUrl = `https://www.zhihu.com/question/x/answer/${target.answerId}`;
// verify the URL loads in the connected Chrome profile before batch-downloading

function isRiskControlBlock(err) {
  return err instanceof Error && err.message.includes('40362');
}

try {
  const answer = await downloadAnswer(target);
} catch (err) {
  if (isRiskControlBlock(err)) {
    console.error('Blocked by Zhihu risk control. Open the answer in Chrome, log in, wait, then retry.');
    await sleep(60_000);
    return downloadAnswer(target); // bounded retries only
  }
  throw err;
}

When it happens

Trigger: Calling the Zhihu answer download flow (extractAnswer, invoked from the download/data command) when the in-page fetch returns { errorCode: '40362' } — i.e. Zhihu's server-side risk control rejected the request for that answerId.

Common situations: Scraping many answers in rapid succession from one account/IP; running headless or in a fresh Chrome profile with no browsing history or login; requesting answers during Zhihu risk-control sweeps; the answer being sensitive/removed and the fetch tripping anomaly detection.
