未找到磁力链接输入框

Error message

未找到磁力链接输入框

What it means

After parsing the detail page, fetchMagnetLink looks for input#input-magnet via doc.Find. If no element matches, the page did not contain the expected magnet-link input, so this error is thrown. It means the DOM structure differs from what the plugin expects — the site changed, was replaced by an error/challenge page, or the URL does not actually point at a resource detail page.

Solutions

1. Dump and inspect the HTML body (log first N chars) when this error occurs to see what the page actually contains.
2. Update the selector in code to match the site's current DOM if the template changed.
3. Detect challenge/error pages (e.g. body contains 'Just a moment' or title mismatch) and retry or rotate UA/cookies instead of parsing them.
4. Check whether the magnet value is rendered by JavaScript; if so, find the JSON/API endpoint the page calls and use that instead of scraping HTML.
5. Fall back to searching alternative magnet selectors or link elements containing 'magnet:' prefixes in the page.

Example fix

// before
magnetInput := doc.Find("input#input-magnet")
if magnetInput.Length() == 0 {
    return "", fmt.Errorf("未找到磁力链接输入框")
}
// after
magnetInput := doc.Find("input#input-magnet")
if magnetInput.Length() == 0 {
    // fallback: scan for a raw magnet link anywhere in the page
    var found string
    doc.Find("a[href^='magnet:']").Each(func(_ int, s *goquery.Selection) {
        if found == "" {
            found, _ = s.Attr("href")
        }
    })
    if found == "" {
        return "", fmt.Errorf("未找到磁力链接输入框")
    }
    return found, nil
}

// after parsing, verify expected structure before extracting
if doc.Find("input#input-magnet").Length() == 0 && doc.Find("a[href^='magnet:']").Length() == 0 {
    return fmt.Errorf("page lacks magnet element (challenge or template change?)")
}

magnet, err := p.fetchMagnetLink(client, detailURL)
if err != nil {
    log.Printf("no magnet found on %s: %v", detailURL, err)
    return "" // keep result without magnet
}

When it happens

Trigger: The parsed HTML has no input element with id "input-magnet": a 200-status anti-bot or JS-rendered challenge page, a site redesign renaming the id, a soft-error page returned with 200, or the magnet being loaded dynamically via JavaScript so it never appears in the raw HTML.

Common situations: The wuji site updating its template so the input id changes; Cloudflare or a JS challenge served with status 200; the magnet input being populated client-side by JS instead of server-side; hitting a generic 'not found' page that still returns 200.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
