java.util.zip.ZipException：尝试下载远程 zip 文件时不是 GZIP 格式

private static String copyFileToLocal(final String inputFile, final String outputFileName) throws IOException {
        writeToOutputFile(new GZIPInputStream(new URL(inputFile).openStream()), outputFileName);
        return outputFileName;
    }
private static void writeToOutputFile(final InputStream inputStream, final String outputFileName) throws IOException{
        final FileOutputStream outputStream = new FileOutputStream(outputFileName, false);
        int gsize = 0;
        final byte data[] = new byte[65536];
        while((gsize = inputStream.read(data)) != -1) {
            outputStream.write(data, 0, gsize);
        }
        inputStream.close();
        outputStream.close();
    }
