Error message

http get: %w

What it means

downloadAudio failed at the second stage: the plain HTTP GET of the resolved downloadURL failed. This is a transport-level error (connection refused, DNS failure, TLS problem, timeout) reported via the injected httpClient.

Solutions

1. Check outbound network connectivity and proxy settings on the host.
2. Re-download promptly — the DingTalk download URL is short-lived; if delayed, fetch a fresh URL via getDownloadURL.
3. Confirm the download URL scheme is https and not corrupted by the webhook payload.
4. If cause is a timeout, increase the httpClient timeout or retry once.

// Pre-check connectivity at startup:
resp, err := http.Get("https://download.dingtalk.com") // or any DingTalk host
if err != nil { log.Fatal("no outbound access to DingTalk CDN: ", err) }
resp.Body.Close()

if err != nil {
    if errors.Is(err, context.DeadlineExceeded) { /* timeout: increase or back off */ }
    log.Warn("audio download failed (network)", "err", err)
    return retryOnce()
}

When it happens

Trigger: p.httpClient.Get(downloadURL) returned a non-nil error while downloading the audio file bytes from the URL obtained from DingTalk.

Common situations: Host has no outbound internet access or a broken proxy; the short-lived download URL already expired (some CDNs then drop connections); DNS misconfiguration; TLS certificate issues in restricted environments.
