我正在使用apache commons来解压缩.tgz文件。我从压缩库中收到错误。我试过压缩版本1.9和1.8.1,我仍然有同样的错误。
这只发生在某些文件上,但是当我手动下载文件并验证它时,没有问题。
$ gunzip -c foo.tgz | tar t > /dev/null
$
但是我看到这个堆栈跟踪来自commons库。
Severe: java.io.IOException: Error detected parsing the header

问题来自
行entry = tarIn.getNextTarEntry();
以下是代码:
try {
TarArchiveInputStream tarIn = new TarArchiveInputStream(
new GZIPInputStream(
new BufferedInputStream(
new FileInputStream(
tempDirPath + fileName))));
TarArchiveEntry entry = tarIn.getNextTarEntry();
while (entry != null) {
File path = new File(tempDirPath, entry.getName());
if (entry.isDirectory()) {
path.mkdirs();
} else {
path.createNewFile();
byte[] read = new byte[1024];
BufferedOutputStream bout = new BufferedOutputStream(new FileOutputStream(path));
int len;
while ((len = tarIn.read(read)) != -1) {
bout.write(read, 0, len);
}
bout.close();
read = null;
}
entry = tarIn.getNextTarEntry();
}
tarIn.close();
} catch (Throwable t) {
t.printStackTrace();
}

尝试使用 GzipCompressorInputStream 装饰您的inputStream。
TarArchiveInputStream tarIn = new TarArchiveInputStream(
new GzipCompressorInputStream(new FileInputStream(fileName)))
