[ ] HTTP错误

Error message

[%s] HTTP错误: %d

What it means

The yuhuage upstream returned an HTTP status other than 200 (and other than the already-handled 429). searchImpl rejects any non-200 response because it expects an HTML search page to parse. The actual code is included in the message.

Solutions

1. Check the status code in the message: 403 means bot detection (update headers/cookies), 5xx means wait and retry.
2. Curl the search URL with the plugin's headers to reproduce and inspect the response.
3. Verify BaseURL (https://www.iyuhuage.fun) and SearchPath are still correct — update if the site moved.
4. Add retry/backoff for transient 5xx, similar to the existing 429 handling.

Example fix

// before
if resp.StatusCode != 200 {
    return nil, fmt.Errorf("[%s] HTTP错误: %d", p.Name(), resp.StatusCode)
}
// after
if resp.StatusCode >= 500 {
    return nil, retryableStatusError{code: resp.StatusCode}
}
if resp.StatusCode != 200 {
    return nil, fmt.Errorf("[%s] HTTP错误: %d", p.Name(), resp.StatusCode)
}

resp, err := http.Get("https://www.iyuhuage.fun/search/test-1-time.html")
if err == nil {
    defer resp.Body.Close()
    if resp.StatusCode != 200 {
        // upstream unhealthy, use alternative plugin
    }
}

results, err := plugin.Search(keyword, ext)
if err != nil {
    var httpErr struct{ code int }
    if strings.Contains(err.Error(), "HTTP错误: 403") {
        log.Printf("yuhuage bot-blocked, using fallback: %v", err)
        return fallbackResults, nil
    }
    if strings.Contains(err.Error(), "HTTP错误: 5") {
        time.Sleep(backoff)
        results, err = plugin.Search(keyword, ext)
    }
}

When it happens

Trigger: resp.StatusCode is not 200 and not 429 — commonly 403 (bot/WAF block), 5xx (server error), 404 (site restructured its search path), or 30x redirect responses.

Common situations: The site enabled Cloudflare bot detection returning 403; temporary upstream outages (502/503); the site changed BaseURL or search path so requests hit a 404; TLS/proxy middleware injecting error pages.
