如何优雅地分离Thrift客户端的连接、协议和调用？

func fundinfoserviceclient() (*fundinfo.fundinfoserviceclient, thrift.TTransport) {
    transportFactory := thrift.NewTFramedTransportFactory(thrift.NewTTransportFactory())
    protocolFactory := thrift.NewTBinaryProtocolFactoryDefault()

    transportSocket, err := thrift.NewTSocket(net.JoinHostPort(ip, port))
    if err != nil {
        fmt.Fprintln(os.Stderr, "无法解析地址:", err)
        os.Exit(1)
    }

    transport, _ := transportFactory.GetTransport(transportSocket)
    client := fundinfo.NewFundInfoServiceClientFactory(transport, protocolFactory)

    if err := transport.Open(); err != nil {
        fmt.Fprintf(os.Stderr, "连接%s:%s失败: %v\n", ip, port, err)
        os.Exit(1)
    }

    return client, transport
}

func GetFundInfo() {
    client, transport := util.FundInfoServiceClient()
    defer transport.Close()

    res, err := client.GetFundInfo(context.Background(), fundcode)
    if err != nil {
        // 处理错误
    }
    // 处理结果 res
}
