In Java FTPClient upload Chinese directory Chinese file name garble code problem solution

Problem description:

  Using Chinese org.apache.commons.net.ftp.FTPClient create directory, upload file name, in Chinese directory name and file name in Chinese is shown as "& # 63; The & # 63;" .

The reason:

  FTP protocol, the file name code is iso-8859-1, so the directory name or file name needs transcoding.

Solutions:

1. Convert the Chinese directory or file name to iso-8859-1 encoded characters. Reference code:

   String name=" Directory name or file name ";
   name=new String(name.getBytes("GBK"),"iso-8859-1");//The converted directory name or file name. < br / >

2. Set Linux environment variables

export LC_ALL="zh_CN.GBK"

export LANG="zh_CN.GBK"

Example:

    public boolean upLoadFile(File file, String path, String fileName) throws IOException {

        boolean result = false;

        FTPClient ftpClient = new FTPClient();

        try {

            ftpClient.connect(confService.getConfValue(PortalConfContants.FTP_CLIENT_HOST));

            ftpClient.login(confService.getConfValue(PortalConfContants.FTP_CLIENT_USERNAME), confService

                    .getConfValue(PortalConfContants.FTP_CLIENT_PASSWORD));

            ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);
            // make directory

            if (path != null && !"".equals(path.trim())) {

                String[] pathes = path.split("/");

                for (String onepath : pathes) {

                    if (onepath == null || "".equals(onepath.trim())) {

                        continue;

                    }
                    onepath=new String(onepath.getBytes("GBK"),"iso-8859-1");                    

                    if (!ftpClient.changeWorkingDirectory(onepath)) {

                        ftpClient.makeDirectory(onepath);

                        ftpClient.changeWorkingDirectory(onepath);

                    }

                }

            }
            result = ftpClient.storeFile(new String(fileName.getBytes("GBK"),"iso-8859-1"), new FileInputStream(file));

        } catch (Exception e) {

            e.printStackTrace();

        } finally {

            ftpClient.logout();

        }

        return result;

    }
