java 将base64编码的gzip数据解码并输出为文本 短示例

import java.io.ByteArrayInputStream; import java.io.ByteArrayOutputStream; import java.io.IOException; import java.util.Base64; import java.util.zip.GZIPInputStream;

public class Base64GzipDecoder {

public static void main(String[] args) throws IOException {
    String base64GzipData = "H4sIAAAAAAAAAM3NzMlNzU3MjU3NTc3MrM0tKgBpJwIAAAAA";
    byte[] decodedData = Base64.getDecoder().decode(base64GzipData);
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    GZIPInputStream gzipInputStream = new GZIPInputStream(new ByteArrayInputStream(decodedData));
    byte[] buffer = new byte[1024];
    int length;
    while ((length = gzipInputStream.read(buffer)) != -1) {
        outputStream.write(buffer, 0, length);
    }
    String text = outputStream.toString("UTF-8");
    System.out.println(text);
}

}

// 输出：Hello World!
