无法正确显示解压进度

[1006079161]

解压无法正确显示解压进度,根本原因在于下面的代码无法正确获取长度

len = toDouble(this$static.d.length_0);
///NOTE: If the data was created via a stream, it will not have a length value, and therefore we can't calculate the progress.
虽然您的注释已经说明了该问题，真的没有办法解决？

Well, is your data read as a stream or not? If the lzma header contains a valid length, then the length_0 field will be it. Otherwise, there is no way for LZMA-JS to know how much of it is left.
