英文:
Java extract .cab files
问题
我想从一个 .cab 文件中提取文件并保存它们。在其他问题和 GitHub 上都没有找到有用的信息。
目前我可以使用 CAB 解析器遍历所有条目（2 个文本文件），但我找不到一个好的方法来保存它们，并且希望能得到一些提示。
File inputFile = new File(inputPath);
File outputPath = new File(inputFile.getParentFile().getAbsolutePath());
final InputStream is = new FileInputStream(inputFile);
CabParser cabParser = new CabParser(is, inputPath);
Arrays.stream(cabParser.files).forEach(element -> {
CabFileEntry cabFile = element;
});
非常感谢！

For now I can iterate through all entries (2 text files) with CAB Parser but I cannot find a good way to save them and would appreciate some hints.
File inputFile = new File(inputPath);
File outputPath = new File(inputFile.getParentFile().getAbsolutePath());
final InputStream is = new FileInputStream(inputFile);
CabParser cabParser = new CabParser(is, inputPath);
Arrays.stream(cabParser.files).forEach(element -> {
CabFileEntry cabFile = element;
});
Thanks a lot!

这似乎适用于 simple.cab：
final InputStream is = new FileInputStream("/tmp/simple.cab");
CabParser cabParser = new CabParser(is, new File("/tmp/simple/"));
cabParser.extractStream();
但是，它在 VC_RED.cab 上失败了。
CabParser README.md：
从通过 LZX 压缩算法压缩的 .cab 文件中提取文件
也许这个库不支持所有可能的压缩算法。
一种选择是使用 cabextract，并使用 Runtime.exec(...) 运行它。
英文:
This seems to work with simple.cab:
final InputStream is = new FileInputStream("/tmp/simple.cab");
CabParser cabParser = new CabParser(is, new File("/tmp/simple/"));
cabParser.extractStream();
However, it fails with VC_RED.cab.
CabParser README.md:
> extract files from within a .cab which are compressed via the LZX compression algorithm
Maybe not all the possible compression algorithms are supported by this library.
One option is to run cabextract with Runtime.exec(...).
