来自这个链接:使用 URLConnection 类上传文件到 FTP 服务器.无需外部库.

From this link: Upload files to FTP server using URLConnection class. No external library necessary.

String ftpUrl = "ftp://%s:%s@%s/%s;type=i"; String host = "www.myserver"; String user = "tom"; String pass = "secret"; String filePath = "E:/Work/Project.zip"; String uploadPath = "/MyProjects/archive/Project.zip"; ftpUrl = String.format(ftpUrl, user, pass, host, uploadPath); System.out.println("Upload URL: " + ftpUrl); try { URL url = new URL(ftpUrl); URLConnection conn = url.openConnection(); OutputStream outputStream = conn.getOutputStream(); FileInputStream inputStream = new FileInputStream(filePath); byte[] buffer = new byte[BUFFER_SIZE]; int bytesRead = -1; while ((bytesRead = inputStream.read(buffer)) != -1) { outputStream.write(buffer, 0, bytesRead); } inputStream.close(); outputStream.close(); System.out.println("File uploaded"); } catch (IOException ex) { ex.printStackTrace(); }
