搜索请求失败，状态码

Error message

搜索请求失败，状态码: %d

What it means

doSearch sends the search request to the u3c3 site and requires HTTP 200. Any other status (403 anti-bot, 429 rate limit, 5xx, redirects to CAPTCHA pages) results in this error. It is a guard ensuring the response body is only parsed for a successful search page.

Solutions

1. Log resp.StatusCode and retry after a delay for 429/5xx
2. Add browser-like headers (User-Agent, Referer, cookies) to pass anti-bot checks
3. Try another mirror domain
4. Route through a proxy/residential IP if the IP is blocked
5. Check the site manually in a browser to see what the status corresponds to

Example fix

// before
if resp.StatusCode != 200 {
    return nil, fmt.Errorf("搜索请求失败，状态码: %d", resp.StatusCode)
}
// after
if resp.StatusCode == 429 {
    time.Sleep(retryAfter)
    return p.doSearch(query) // retry
}
if resp.StatusCode != 200 {
    return nil, fmt.Errorf("搜索请求失败，状态码: %d", resp.StatusCode)
}

results, err := u3c3Plugin.SearchWithResult(ctx, query)
var httpErr *HTTPStatusError
if errors.As(err, &httpErr) && (httpErr.Code == 429 || httpErr.Code >= 500) {
    time.Sleep(backoff)
    results, err = u3c3Plugin.SearchWithResult(ctx, query)
}

When it happens

Trigger: SearchWithResult or TestU3c3LiveSearch reaching doSearch when the server responds with a non-200 status: 403 from Cloudflare/anti-bot, 429 rate limiting, 503 during site maintenance, or 30x not followed.

Common situations: Sending too many rapid requests and being rate-limited; the mirror serving a Cloudflare challenge; the site being under maintenance; stale domain redirecting to a block page.
