HTTP状态码

Error message

HTTP状态码: %d

What it means

Internal error created by doRequestWithRetry when the server responded but with a non-200 status code. The response body is closed and the status is recorded as lastErr; if all retries fail with status errors, this becomes the wrapped cause of error 475. It is a sentinel describing the HTTP status, not a full error type.

Solutions

1. Capture and log a portion of the response body before closing it to learn why the status was non-200
2. Back off and retry later if the status is 429 (rate limited)
3. Rotate IP / use a proxy if 403 WAF blocks persist
4. Check whether the base URL https://woog.nxog.eu.org/ is still the correct endpoint

Example fix

// before
resp.Body.Close()
lastErr = fmt.Errorf("HTTP状态码: %d", resp.StatusCode)
// after
snippet, _ := io.ReadAll(io.LimitReader(resp.Body, 256))
resp.Body.Close()
lastErr = fmt.Errorf("HTTP状态码: %d, body=%.256s", resp.StatusCode, snippet)

if err != nil && strings.Contains(err.Error(), "HTTP状态码: 429") {
    time.Sleep(time.Duration(jitter(2, 10)) * time.Second)
    return retry()
}

When it happens

Trigger: client.Do succeeds and resp.StatusCode != http.StatusOK on every retry attempt (e.g. 403, 429, 500, 502 from woog.nxog.eu.org); only the numeric status is kept, discarding the response body that may contain the real reason.

Common situations: IP rate-limited (429) by the API; Cloudflare/WAF challenge (403); upstream origin down behind a proxy (502/503); the site moved and old host returns 404.
