[ ] 请求返回状态码

Error message

[%s] 请求返回状态码: %d

What it means

The ASH search endpoint responded, but with a status code other than 200. searchImpl treats any non-200 as a hard failure and reports the code so the caller can react. Body is already closed at this point, so only the status code is available.

Solutions

1. Log the status code and retry later if 429/5xx; back off the request rate.
2. Handle 403 by rotating headers/User-Agent, cookies, or using a proxy/residential IP.
3. Verify the search URL path is still valid if you get 404 (site layout changed).
4. Optionally treat the body of non-200 responses as diagnostic info before discarding it.

Example fix

// before
if resp.StatusCode != 200 {
    return nil, fmt.Errorf("[%s] 请求返回状态码: %d", p.Name(), resp.StatusCode)
}
// after
if resp.StatusCode != 200 {
    if resp.StatusCode == http.StatusTooManyRequests {
        time.Sleep(retryAfterFrom(resp.Header))
    }
    io.Copy(io.Discard, io.LimitReader(resp.Body, 4096))
    return nil, fmt.Errorf("[%s] 请求返回状态码: %d", p.Name(), resp.StatusCode)
}

// after response
if resp.StatusCode != 200 { return fmt.Errorf("upstream status %d", resp.StatusCode) }

var statusErr *StatusError
if errors.As(err, &statusErr) {
    switch {
    case statusErr.Code == 429: backoffAndRetry()
    case statusErr.Code >= 500: retryLater()
    default: alertOnBlocked(statusErr.Code)
    }
}

When it happens

Trigger: After doRequestWithRetry succeeds, resp.StatusCode != 200 — e.g. 403 (blocked/Cloudflare), 429 (rate limited), 404 (path changed), 5xx (server error) — ash.go:99.

Common situations: Upstream added WAF/anti-bot protection returning 403; request rate too high causing 429; the site changed its search path causing 404; origin server 5xx during load.
