Java无法解压Python压缩并Base64编码的字符串问题求助

我在Java中尝试解压一段由Python压缩并经Base64编码的字符串，折腾了一整天还是没成功。这段内容在在线工具和Python环境里都能正常解码，我也查过不少Java和Python跨语言压缩解压的相关问题，但依旧没能解决。

初始实现代码 #

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.util.Base64;
import java.util.zip.DataFormatException;
import java.util.zip.Deflater;
import java.util.zip.Inflater;

public class CompressionUtils {
private static final int BUFFER_SIZE = 1024;

public static byte[] decompress(final byte[] data) {
    final Inflater inflater = new Inflater();
    inflater.setInput(data);
    ByteArrayOutputStream outputStream =
            new ByteArrayOutputStream(data.length);
    byte[] buffer = new byte[data.length];
    try {
        while (!inflater.finished()) {
            final int count = inflater.inflate(buffer);
            outputStream.write(buffer, 0, count);
        }
        outputStream.close();
    } catch (DataFormatException | IOException e) {
        e.printStackTrace();
        log.error("ZlibCompression decompress exception: {}", e.getMessage());
    }
    inflater.end();
    return outputStream.toByteArray();
}

public static void main(String[] args) throws IOException {
    decompress(Base64.getDecoder().decode(Files.readAllBytes(Path.of("zip.txt"))));
}
}

初始代码报错 #

java.util.zip.DataFormatException: incorrect header check
    at java.base/java.util.zip.Inflater.inflateBytesBytes(Native Method)
    at java.base/java.util.zip.Inflater.inflate(Inflater.java:378)
    at java.base/java.util.zip.Inflater.inflate(Inflater.java:464) 

按建议修改后的代码 #

public static void main(String[] args) throws IOException {
    
    byte[] decoded = Base64.getDecoder().decode(Files.readAllBytes(Path.of("zip.txt")));
    ByteArrayInputStream in = new ByteArrayInputStream(decoded);
    GZIPInputStream gzStream = new GZIPInputStream(in);
    decompress(gzStream.readAllBytes());
    gzStream.close();
}

修改后仍出现的报错 #

java.util.zip.DataFormatException: incorrect header check
at java.base/java.util.zip.Inflater.inflateBytesBytes(Native Method)
at java.base/java.util.zip.Inflater.inflate(Inflater.java:378)
