我有一个首先压缩的字符串(不是gzip),然后是base64编码的。 我想再次使用纯文本。以下代码
private void decode_decompress(String string) {
byte[] decodedBytes = Base64.decodeBase64(string.getBytes());
ByteArrayOutputStream stream = new ByteArrayOutputStream();
Inflater decompresser = new Inflater(true);
InflaterOutputStream inflaterOutputStream = new InflaterOutputStream(stream, decompresser);
try {
inflaterOutputStream.write(decodedBytes);
inflaterOutputStream.close();
byte[] output2 = stream.toByteArray();
logger.info("Data: {}", output2.toString());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
抛出异常:
java.util.zip.ZipException: invalid stored block lengths

我想,我正在混合输入/输出膨胀/放气
以下是压缩和base64编码的数据:

答案 0 :(得分:1)
这解决了这个问题:
private void decode_decompress(String string) {
byte[] decodedBytes = Base64.decodeBase64(string);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
Inflater decompresser = new Inflater(false);
InflaterOutputStream inflaterOutputStream = new InflaterOutputStream(stream, decompresser);
try {
inflaterOutputStream.write(decodedBytes);
inflaterOutputStream.close();
String data = stream.toString();
logger.info("Data: {}", data);
} catch (IOException e) {
logger.error(string, e);
}
}
