请求失败: %v

Error message

请求失败: %v

What it means

Thrown by Eranet.request when client.Do(req) fails — the HTTP request to https://www.eranet.com could not be completed at the transport level. This wraps the net/http error (DNS failure, connection refused/reset, timeout, TLS error), affecting create, modify, and getRecordList.

Solutions

1. Check basic connectivity to https://www.eranet.com (curl -v) from the host running the program
2. Check DNS resolution of www.eranet.com on that host
3. Retry the request — this is often transient; consider adding backoff/retry in create/modify paths
4. If behind a proxy, configure the proxy for the http.Client; if a timeout was configured, increase it
5. Verify system time is correct — clock skew causes TLS handshake failures

Example fix

// before
resp, err := client.Do(req)
if err != nil {
    return nil, fmt.Errorf("请求失败: %v", err)
}
// after
resp, err := client.Do(req)
if err != nil {
    return nil, fmt.Errorf("请求失败: %w", err) // retry with backoff at caller
}

// preflight connectivity check
resp, err := http.Get("https://www.eranet.com")
if err != nil {
    return fmt.Errorf("eranet unreachable, check network/DNS/proxy: %w", err)
}
resp.Body.Close()

var dnsErr *net.DNSError
if errors.As(err, &dnsErr) {
    // DNS-level failure vs connection/timeout failure
}

body, err := eranetClient.CreateRecord(params)
if err != nil {
    if strings.Contains(err.Error(), "请求失败") {
        return retryWithBackoff(3, func() error {
            _, err = eranetClient.CreateRecord(params)
            return err
        })
    }
    return err
}

When it happens

Trigger: Any Eranet API call where the network round-trip fails: DNS resolution failure for www.eranet.com, TCP connection refused/reset, request timeout via t.httpClient, TLS handshake failure, or no network connectivity.

Common situations: Running ddns-go behind a firewall/proxy that blocks eranet.com; intermittent ISP or DNS outages; overly aggressive httpClient timeout; corporate MITM proxies breaking TLS; transient network flaps during DNS updates.

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.
