读取响应失败: %v

Error message

读取响应失败: %v

What it means

This error is thrown by the Tnet.hk DNS provider's internal request() helper in dns/tnethk.go:279 when io.ReadAll(resp.Body) fails after a successful HTTP round-trip to https://www.tnet.hk. The API call itself connected, but the response body could not be read — typically a mid-stream connection reset, timeout, or truncated response. It propagates out of create, modify and getRecordList as the returned error.

Solutions

1. Retry the request — the failure is almost always transient network/stream related
2. Check connectivity/stability to https://www.tnet.hk (curl the same endpoint) and any proxy in between
3. Increase or verify the http.Client timeout used by the Tnethk provider
4. Check Tnet.hk API status; a server dropping connections mid-response is on their side

// Go: verify reachability before provider calls
resp, err := http.Get("https://www.tnet.hk")
if err != nil {
    log.Fatalf("tnet.hk unreachable: %v", err)
}
resp.Body.Close()

// Go
for i := 0; i < 3; i++ {
    records, err := provider.GetRecordList(domain)
    if err == nil {
        break
    }
    if strings.Contains(err.Error(), "读取响应失败") {
        time.Sleep(time.Duration(1<<i) * time.Second) // backoff and retry
        continue
    }
    return err // non-transient
}

When it happens

Trigger: Any signed request to the Tnet.hk API (record create, modify, or list) where the server closes/resets the connection partway through the response, the 30s client timeout fires while reading the body, or a proxy/NAT truncates the stream.

Common situations: Unstable network or VPN to tnet.hk; server-side gateway timeouts returning partial bodies; corporate middleboxes killing keep-alive connections; transient outages of the Tnet API.
