我在下载gzip文件并将其保存在 Java 5 的文件系统中时遇到问题。下载完成后,文件(具有正确的名称和扩展名)似乎具有不同的 MIME 类型......我无法从我的 Linux 服务器(使用gunzip)解压缩它,如果我尝试在我的 Windows 电脑上使用 WinZip 打开它,我会看到一个“递归”存档(如俄罗斯套娃)。如果我file *filename*.gz从服务器键入命令,它会将文件识别为ascii text. 相反,如果我尝试使用浏览器下载存档,一切顺利,我可以正确打开和解压缩文件(即使使用我的 Linux 服务器),现在它被识别为gzip compressed archive.这是我用来下载文件并保存的代码。主.java:public class Main {public static void main(String[] args) { String filePath = ""; HttpOutgoingCall httpOngoingCall = null; httpOngoingCall = new HttpOutgoingCall(); String endpointUrl = "https://myurl/myfile.gz"; try { InputStream inputStream = httpOngoingCall.callHttps(endpointUrl); //I also tried with ZipInputStream and GZIPInputStream BufferedReader br = new BufferedReader(new InputStreamReader(inputStream)); filePath = parseAndWriteResponse(br, "myfile.gz", "C:\\"); System.out.println(filePath); } catch (Exception e) { System.out.println(e.getMessage()); }}private static String parseAndWriteResponse(BufferedReader br, String fileName, String destPath) { String outputFileName = null; outputFileName = destPath + File.separator + fileName; String line; File outputFile = new File(outputFileName); FileWriter fileWriter = null; BufferedWriter bw = null; try { if (!outputFile.exists()) { outputFile.createNewFile(); } } catch (IOException e1) { } try { fileWriter = new FileWriter(outputFile); bw = new BufferedWriter(fileWriter); while ((line = br.readLine()) != null) { bw.write(line); bw.write("\n"); } } catch (IOException e) { } finally { try { bw.close(); fileWriter.close(); } catch (IOException e) { } } return outputFileName;}
