[ ] 未能抓取到有效网盘链接

Error message

[%s] 未能抓取到有效网盘链接

What it means

After concurrently fetching each thread's detail page, searchImpl fails with '[%s] 未能抓取到有效网盘链接' when no worker extracted any valid pan (net-disk) links. All detail fetches either failed or the pages contained no recognizable share links.

Solutions

1. Check one thread detail page in a browser to confirm whether share links are still present and guest-visible
2. Add/refresh cookies or authentication so detail pages return real links instead of placeholders
3. Slow the workers (lower detailWorkerCount) or add retries to avoid anti-bot rate limiting
4. Update the link-extraction patterns if the forum changed how pan links are rendered
5. Verify network/proxy health so detail requests are not all failing

Example fix

// before
sem = make(chan struct{}, detailWorkerCount)
// after
sem = make(chan struct{}, 2) // reduce concurrency to avoid anti-bot blocks on detail pages

// cannot pre-validate; guard after the call
if err != nil && strings.Contains(err.Error(), "未能抓取到有效网盘链接") { /* retry or fallback */ }

func isNoLinksErr(err error) bool { return err != nil && strings.Contains(err.Error(), "未能抓取到有效网盘链接") }

results, err := plugin.Search(ctx, keyword)
if isNoLinksErr(err) {
    // retry once with lower concurrency / fresh cookies, else fall back to another plugin
    time.Sleep(time.Second)
    results, err = plugin.Search(ctx, keyword)
}
if err != nil { return err }

When it happens

Trigger: Every fetched thread detail contains no valid cloud-drive links — posts were deleted/link-stripped, detail pages require login, anti-bot blocks the detail requests, or the link-extraction regex no longer matches the page markup.

Common situations: Forum purges or hides share links for old posts; guests see link placeholders instead of real URLs; detail request rate-limited so all workers get challenge pages; site changed its link format so extraction returns nothing.

Understand the failure class

Background: EmptyResultError / "no results found": when an API or scraper succeeds but returns zero rows — this error's family across 9 libraries.
