[ ] 搜索请求HTTP状态错误

Error message

[%s] 搜索请求HTTP状态错误: %d

What it means

executeSearchWithRateLimit returns '[javdb] 搜索请求HTTP状态错误: %d' (search request HTTP status error) when the response status is not 200 (and not the specially handled 429 rate-limit case). It indicates javdb responded but rejected the request — commonly a bot-block or server error page.

Solutions

1. Log the status code and body snippet to identify 403 vs 5xx vs 404
2. Refresh User-Agent/Accept headers and consider cookie handling to pass anti-bot checks
3. Enable/verify redirect following on the http.Client (CheckRedirect)
4. Retry with backoff on 5xx statuses
5. Check whether javdb moved the search endpoint and update searchURL

// Go: verify the endpoint still returns 200 with current headers before scraping
req, _ := http.NewRequest("GET", searchURL, nil)
req.Header.Set("User-Agent", UserAgent)
resp, err := http.DefaultClient.Do(req)
if err == nil && resp.StatusCode != 200 {
    log.Printf("javdb probe returned %d", resp.StatusCode)
}

func isTransientStatus(code int) bool {
    return code == 429 || code >= 500
}

if resp.StatusCode != 200 {
    if isTransientStatus(resp.StatusCode) {
        return retryWithBackoff(req)
    }
    return nil, fmt.Errorf("javdb HTTP %d", resp.StatusCode), false
}

When it happens

Trigger: client.Do succeeds but resp.StatusCode is anything other than 200 after the 429 branch — e.g. 403 from anti-bot protection, 301/302 not followed due to redirect policy, 503 from upstream overload.

Common situations: Site deployes stricter Cloudflare/anti-scraping checks; User-Agent header list becomes stale; cookies/CF clearance missing; site moved the endpoint and returns 404.
