无法获取最新的 year 和 issue

Error message

无法获取最新的 year 和 issue

What it means

社会学杂志 (shxyj.ajcass.com) route scrapes the homepage to discover the latest year/issue from a `p.hod.pop` element via the regex /(\d{4}) Vol\.(\d+):/. If neither the selector nor the regex matches (markup changed, or no issue line present), it throws a generic `Error('无法获取最新的 year 和 issue')`.

Solutions

1. Supply explicit year and issue in the path so the homepage scrape is bypassed entirely.
2. If you maintain the route, inspect https://shxyj.ajcass.com/ and update the selector ('p.hod.pop') and/or the regex.
3. Retry later for transient homepage changes (e.g. a holiday banner).

Example fix

// before — relies on homepage scrape, throws when markup changes
if (match) { year = match[1]; issue = match[2]; }
else { throw new Error('无法获取最新的 year 和 issue'); }
// after — tolerate format drift by trying alternate selectors
const m = latestIssueText.match(/(\d{4})\s*Vol\.?\s*(\d+)/) ?? $('a:contains("Vol")').first().text().match(/(\d{4})\/?(\d+)/);
if (!m) throw new Error('无法获取最新的 year 和 issue');
// OR call with explicit params: /ajcass/shxyj/2024/5

// If you can supply explicit values, bypass the homepage scrape entirely:
function explicitShxyjArgs(year, issue) {
  return /^\d{4}$/.test(String(year)) && /^\d+$/.test(String(issue));
}

function isExplicitIssue(year, issue): boolean {
  return /^\d{4}$/.test(String(year ?? '')) && /^\d+$/.test(String(issue ?? ''));
}

let year = ctxYear, issue = ctxIssue;
if (!year || !issue) {
  try {
    const $ = load((await got('https://shxyj.ajcass.com/')).body);
    const m = $('p.hod.pop').first().text().match(/(\d{4})\s*Vol\.?\s*(\d+)/);
    if (!m) throw new Error('无法获取最新的 year 和 issue');
    [year, issue] = [m[1], m[2]];
  } catch (e) {
    // fallback: try an alternate selector or a known-good recent issue
    const m2 = $('a:contains("Vol")').first().text().match(/(\d{4})/);
    if (!m2) throw e;
    year = m2[1]; issue = '1';
  }
}

When it happens

Trigger: Calling /ajcass/shxyj without explicit year/issue params when the homepage markup has changed — selector `p.hod.pop` absent, or text no longer matches 'YYYY Vol.N:'.

Common situations: Site redesign renamed the CSS class; the homepage is temporarily showing a special-issue banner without the expected text format; the journal changed its issue-naming scheme.
