Failed to fetch data from API

Error message

Failed to fetch data from API

What it means

Generic Error from a catch block wrapping got.post to the BNU (Beijing Normal University) faculty CMS API. Any thrown network/HTTP error is swallowed and re-thrown as this generic message, hiding the original cause. It signals the POST to fe.bnu.edu.cn's column listing endpoint could not complete.

Solutions

1. Retry — campus CMS endpoints are intermittently flaky.
2. Verify https://fe.bnu.edu.cn is reachable from the RSSHub host (curl the apiUrl with the same headers).
3. If persistent, inspect the original error by temporarily logging it in the catch (the bare `catch {}` currently swallows it).
4. Update the Referer/Origin/X-Requested-With headers if the CMS changed its CSRF checks.

Example fix

// before
} catch {
    throw new Error('Failed to fetch data from API');
}
// after (preserve the cause for diagnosis)
} catch (e) {
    throw new Error('Failed to fetch data from API: ' + (e instanceof Error ? e.message : String(e)));
}

try {
    response = await got.post(apiUrl, { headers, body: `columnid=${category}&page=1` });
} catch (e) {
    throw new Error('Failed to fetch data from API: ' + (e instanceof Error ? e.message : String(e)));
}

// Wrap with a bounded retry for transient campus-network failures:
let response, lastErr;
for (let i = 0; i < 3; i++) {
    try { response = await got.post(apiUrl, { headers, body }); break; }
    catch (e) { lastErr = e; await delay(500 * (i + 1)); }
}
if (!response) throw new Error('Failed to fetch data from API: ' + lastErr);

When it happens

Trigger: got.post to the apiUrl threw — connection reset, DNS failure, non-2xx status that got treats as an error, or a socket timeout. The catch (no binding) discards the original error and throws the generic string.

Common situations: The BNU site is down or rate-limiting; the server IP is blocked by the campus firewall; TLS/cert issues; the hardcoded Referer/Origin headers being rejected after a site change.
