[英]Decompressing to a byte[] using GzipInputStream
I have a class that compresses and decompresses a byte array; 我有一个压缩和解压缩字节数组的类;
public class Compressor
{
public static byte[] compress(final byte[] input) throws IOException
{
try (ByteArrayOutputStream bout = new ByteArrayOutputStream();
GZIPOutputStream gzipper = new GZIPOutputStream(bout))
{
gzipper.write(input, 0, input.length);
gzipper.close();
return bout.toByteArray();
}
}
public static byte[] decompress(final byte[] input) throws IOException
{
try (ByteArrayInputStream bin = new ByteArrayInputStream(input);
GZIPInputStream gzipper = new GZIPInputStream(bin))
{
// Not sure where to go here
}
}
}
How do I decompress the input and return a byte array? 如何解压缩输入并返回字节数组?
Note: I don't want to do any conversion to strings because of character encoding issues. 注意:由于字符编码问题,我不想对字符串进行任何转换。
your missing code will be something like 你丢失的代码就像是
byte[] buffer = new byte[1024];
ByteArrayOutputStream out = new ByteArrayOutputStream();
int len;
while ((len = gzipper.read(buffer)) > 0) {
out.write(buffer, 0, len);
}
gzipper.close();
out.close();
return out.toByteArray();
