[ ] 搜索请求返回 HTTP

Error message

[%s] 搜索请求返回 HTTP %d

What it means

The HTTP request succeeded but the server responded with a status code other than 200 OK, so the plugin refuses to parse the body and returns this error. The site likely returned a redirect to a captcha/login page, a 403 anti-bot response, a 404, or a 5xx server error. Note the message does not wrap an underlying error — the status code itself is the information.

Solutions

1. Log or inspect resp.StatusCode (and the body) to identify what the server actually returned.
2. Update the plugin's baseURL/searchPath if the site moved (404 case).
3. Check cookies/headers: add realistic User-Agent and reuse cookies if the site requires a session (403/captcha case).
4. Back off and retry later for 5xx responses.

Example fix

// before
if resp.StatusCode != http.StatusOK {
	return nil, fmt.Errorf("[%s] 搜索请求返回 HTTP %d", p.Name(), resp.StatusCode)
}
// after
if resp.StatusCode != http.StatusOK {
	snippet, _ := io.ReadAll(io.LimitReader(resp.Body, 512))
	return nil, fmt.Errorf("[%s] 搜索请求返回 HTTP %d, body: %s", p.Name(), resp.StatusCode, snippet)
}

if resp.StatusCode != http.StatusOK {
	return fmt.Errorf("HTTP %d: inspect headers/body for captcha, redirect, or outage", resp.StatusCode)
}

When it happens

Trigger: After client.Do, resp.StatusCode != http.StatusOK for the POST to baseURL+searchPath — e.g. 403 from WAF/anti-bot, 404 after a site URL structure change, 302 to a verification page, 500/502/503 from the upstream server.

Common situations: The target site changed its URL or enabled anti-scraping (Cloudflare challenge), an outdated baseURL in config, rate-limiting after frequent searches, or transient upstream outages.
