[BUG] panic: interface conversion: http.RoundTripper is nil, not *http.Transport

[febelery]

使用的版本

• SDK 版本：v2.1.7

报错文件 util/http.go#293

// httpWithTLS CA 证书
func httpWithTLS(rootCa, key string) (*http.Client, error) {
	var client *http.Client
	certData, err := os.ReadFile(rootCa)
	if err != nil {
		return nil, fmt.Errorf("unable to find cert path=%s, error=%v", rootCa, err)
	}
	cert := pkcs12ToPem(certData, key)
	config := &tls.Config{
		Certificates: []tls.Certificate{cert},
	}
	trans := (DefaultHTTPClient.Transport.(*http.Transport)).Clone()
	trans.TLSClientConfig = config
	trans.DisableCompression = true
	client = &http.Client{Transport: trans}
	return client, nil
}

trans := (DefaultHTTPClient.Transport.(*http.Transport)).Clone()

DefaultHTTPClient.Transport 这个为nil

util/http.go 文件第26行可以改成

var DefaultHTTPClient = &http.Client{
    Transport: http.DefaultTransport,
}
