[ ] 搜索请求返回状态码
Error message
[%s] 搜索请求返回状态码: %d
What it means
The duoduo search HTTP request succeeded at the transport level but returned a status code other than 200, so searchImpl rejects the response instead of parsing it. The plugin treats any non-200 as fatal because it expects an HTML search results page. This is an upstream site behavior problem, not a bug in the caller's request.
Solutions
- Log resp.StatusCode and the response body snippet to identify whether it's a WAF block, rate limit, or server error.
- Rotate/randomize User-Agent and consider cookie handling or a real browser-like header set to pass anti-bot checks.
- Back off and retry with exponential delay on 429/5xx instead of failing immediately.
- If 403 persists, the site likely blocks non-browser clients — switch data source or use a headless-browser fetch.
Example fix
// before
if resp.StatusCode != 200 {
return nil, fmt.Errorf("[%s] 搜索请求返回状态码: %d", p.Name(), resp.StatusCode)
}
// after
if resp.StatusCode == 429 || resp.StatusCode >= 500 {
time.Sleep(retryBackoff)
// retry once before giving up
} else if resp.StatusCode != 200 {
return nil, fmt.Errorf("[%s] 搜索请求返回状态码: %d", p.Name(), resp.StatusCode)
} Defensive patterns
Strategy: retry
Try / catch
if err != nil {
var statusErr interface{ StatusCode() int }
// or inspect resp.StatusCode before parsing:
if resp.StatusCode == 429 {
time.Sleep(backoff)
// retry
} else if resp.StatusCode >= 500 {
// retry with backoff
} else {
// 403/404: likely blocked; disable source or change headers
}
} Prevention
- Send complete browser-like header sets to pass WAF checks.
- Throttle request rate to avoid 429s.
- Treat 5xx/429 as retryable, 4xx as non-retryable.
- Log response bodies on unexpected statuses for diagnosis.
When it happens
Trigger: The GET to the search URL returns 403/429/503 etc., typically when anti-bot protection (Cloudflare or similar) blocks the request, the Referer/UA headers are insufficient, or the site is rate-limiting frequent searches.
Common situations: Repeated automated searches trigger rate limiting (429); Cloudflare/WAF challenge page returned (403 or 503); site moved and old URL now redirects to an error page; server temporarily overloaded (5xx).
