[ ] 搜索请求HTTP状态错误
Error message
[%s] 搜索请求HTTP状态错误: %d
What it means
Status error in hdmoli's executeSearch (plugin/hdmoli/hdmoli.go:140): the search request succeeded at transport level but returned a non-200 status after retries. Note this record's message at the throw site is the wrapped '搜索请求失败: %w' from doRequestWithRetry; the status-check path reports the HTTP code, indicating the site refused or rate-limited the search.
Solutions
- Log the status code and response body snippet to see what the server returned
- For 403/429: slow down request rate, rotate User-Agent, or obtain needed cookies
- For 404: update the plugin's search path to the site's current URL structure
- Ensure CheckRedirect is enabled and redirect responses are followed
Example fix
// before
if resp.StatusCode != 200 {
return nil, fmt.Errorf("[%s] 搜索请求HTTP状态错误: %d", p.Name(), resp.StatusCode)
}
// after
if resp.StatusCode != 200 {
body, _ := io.ReadAll(io.LimitReader(resp.Body, 512))
return nil, fmt.Errorf("[%s] 搜索请求HTTP状态错误: %d, body: %s", p.Name(), resp.StatusCode, body)
} Defensive patterns
Strategy: retry
Validate before calling
// Go: inspect status before treating as failure
if resp.StatusCode == http.StatusForbidden || resp.StatusCode == http.StatusTooManyRequests {
time.Sleep(backoff) // honor rate limiting before retrying
} Try / catch
if resp.StatusCode != 200 {
body, _ := io.ReadAll(io.LimitReader(resp.Body, 256))
log.Printf("hdmoli status %d: %s", resp.StatusCode, body)
// branch on code: 403/429 => backoff & rotate UA; 404 => update URL
} Prevention
- Send browser-like headers (UA, Accept, Referer) to reduce 403s
- Rate-limit requests to avoid 429
- Update selectors/URL paths when the site is redesigned
- Log response bodies on unexpected statuses
When it happens
Trigger: The server replies 403/429 (anti-bot or rate limiting), 404 (search path changed), 5xx (server error), or 301/302 that were not followed by the client.
Common situations: 缺少 Referer 触发防盗链；高频搜索被限流。
