[ ] 首页返回状态码

Error message

[%s] 首页返回状态码: %d

What it means

Returned when the homepage request succeeds at the transport level but the server responds with a status code other than 200 OK. The plugin treats any non-200 homepage response as a hard failure and includes the numeric status in the message.

Solutions

1. Log/read the status code in the message: 403/429 means blocking — change or rotate User-Agent headers in setHTMLHeaders
2. Back off and retry later for 5xx codes (server-side problem)
3. Reduce request frequency / add caching to avoid rate limits
4. Check https://jsnoteclub.com/ manually in a browser to see if the site changed or moved
5. Inspect response body for Cloudflare challenge pages and adjust headers accordingly

Example fix

// before
if resp.StatusCode != http.StatusOK {
    return "", fmt.Errorf("[%s] 首页返回状态码: %d", p.Name(), resp.StatusCode)
}
// after
if resp.StatusCode != http.StatusOK {
    return "", fmt.Errorf("[%s] 首页返回状态码: %d", p.Name(), resp.StatusCode) // 403/429 => adjust User-Agent; 5xx => retry with backoff
}

key, err := plugin.fetchDataKey(client)
if err != nil {
    var statusErr interface{ Error() string }
    if strings.Contains(err.Error(), "首页返回状态码") {
        // non-200 from upstream: handle 403/429 by rotating headers, 5xx by waiting
        return handleUpstreamStatus(err)
    }
    _ = statusErr
    return err
}

When it happens

Trigger: GET https://jsnoteclub.com/ returns e.g. 403 (bot blocking/WAF), 429 (rate limit), 5xx (server error), or a 3xx that was not followed to a 200.

Common situations: Cloudflare or nginx blocking the plugin's User-Agent; server under maintenance returning 502/503; hitting the site too frequently and being rate limited; the site moved/redirected in a way the client's CheckRedirect policy rejects.
