搜索请求返回状态码

Error message

搜索请求返回状态码: %d

What it means

The results-page request completed but returned a status other than 200. searchPage requires exactly http.StatusOK to parse results, so any 3xx/4xx/5xx (after redirect handling was reset) aborts with "搜索请求返回状态码: %d".

Solutions

Log the status code and response body to see what the server returned.
Handle 302 by following to a captcha/login flow or re-running the search to get a fresh searchid.
Reduce request rate / add delays and caching to avoid WAF 403/429.
Update headers/cookies if the site added bot protection.
Check site availability status for 5xx before blaming the plugin.

Example fix

// before
if resp2.StatusCode != http.StatusOK {
    return nil, fmt.Errorf("搜索请求返回状态码: %d", resp2.StatusCode)
}
// after
if resp2.StatusCode != http.StatusOK {
    body, _ := io.ReadAll(io.LimitReader(resp2.Body, 512))
    return nil, fmt.Errorf("搜索请求返回状态码: %d, body: %s", resp2.StatusCode, body)
}

Defensive patterns

Strategy: retry

Validate before calling

// Go: check site availability before calling the plugin
resp, err := http.Get(baseURL)
if err != nil || resp.StatusCode >= 500 {
    return nil, fmt.Errorf("panwiki site currently unhealthy")
}

Try / catch

results, err := plugin.Search(keyword, page)
if err != nil {
    var statusErr interface{ Error() string }
    if strings.Contains(err.Error(), "搜索请求返回状态码: 403") || strings.Contains(err.Error(), "状态码: 429") {
        // back off significantly; you are being rate limited/blocked
    }
    return err
}

Prevention

Rate-limit searches and cache results to avoid WAF triggers.
Send realistic browser headers and keep them updated.
Handle login-required flows if the site gates search behind auth.
Alert on sustained non-200 responses as upstream breakage.

When it happens

Trigger: resp2.StatusCode != 200 — e.g. 302 back to a captcha/login page, 403 from anti-bot (Cloudflare/WAF), 404 because the searchid expired, 429 rate limiting, or 502/503 upstream errors.

Common situations: Search ID expired between the two requests; too-frequent searches triggering WAF blocks; site requires login for search; server-side outage (5xx).
