如何等待将数据添加到多链块中？

我正在尝试通过以下代码在流中添加数据。

mc.publish({ stream: "datastream", key: "through", data: packet }).then(x => {
    sucess++;
    //total_size += passedSize;
    callback(null, sucess);

}).catch(y => {
    //sucess++;
    //total_size += passedSize;
    callback(null, sucess);
})

此代码在将数据添加到未使用的池中时返回回调，但是我要等到将其添加到块中之后。

这里是我使用的参数。

如何进行多链处理？有什么主意吗？

谢谢。
