[ ] 重试 次后仍然失败

Error message

[%s] 重试 %d 次后仍然失败: %w

What it means

doRequestWithRetry exhausted all its retry attempts without receiving a 200 response. The final underlying cause (transport error or the last non-200 status, e.g. 'HTTP状态码: %d') is wrapped by %w. The plugin's search cannot complete without a successful HTTP response.

Solutions

1. Read the wrapped cause to distinguish transport failure (network) from HTTP status failure (server/bot protection).
2. Test connectivity to the target host from the same machine (curl -v).
3. Update cookies, User-Agent, or use a proxy if the site is blocking the client.
4. Wait and retry — for 5xx/429 the upstream often recovers; consider longer backoff.

// pre-flight reachability check
if _, err := http.Head(targetURL); err != nil {
    log.Printf("target unreachable, aborting early: %v", err)
}

results, err := searchImpl(keyword)
if err != nil {
    if strings.Contains(err.Error(), "重试") {
        log.Printf("exhausted retries, serving cached results: %v", err)
        return cachedResults(), nil
    }
    return err
}

When it happens

Trigger: doRequestWithRetry: after maxRetries attempts, every client.Do call either returned a transport error or a non-200 status code.

Common situations: Target site down or geo-blocked, DNS failure, local network/proxy outage, persistent 403/429 from anti-bot protection, TLS handshake failures.

Understand the failure class

Background: 'Something went wrong' / 'Request failed (500)' / 'HTTP error! status: 404' — what failed HTTP requests actually mean and how to find the real cause — this error's family across 28 libraries.
