FTP上传错误“553无法创建文件”

import org.apache.commons.net.ftp.FTPClient; import org.apache.commons.net.ftp.FTPReply; import org.apache.commons.net.ftp.FTPFile; import java.io.*; public class FTPUpload{ public static boolean uploadfile(String server,String username,String Password,String source_file_path,String dest_dir){ FTPClient ftp=new FTPClient(); try { int reply; ftp.connect(server); ftp.login(username, Password); System.out.println("Connected to " + server + "."); System.out.print(ftp.getReplyString()); reply = ftp.getReplyCode(); if(!FTPReply.isPositiveCompletion(reply)) { ftp.disconnect(); System.err.println("FTP server refused connection."); return false; } System.out.println("FTP server connected."); InputStream input= new FileInputStream(source_file_path); ftp.storeFile(dest_dir, input); System.out.println( ftp.getReplyString() ); input.close(); ftp.logout(); } catch(Exception e) { System.out.println("err"); e.printStackTrace(); return false; } finally { if(ftp.isConnected()) { try { ftp.disconnect(); } catch(Exception ioe) { } } } return true; } public static void main(String[] args) { FTPUpload upload = new FTPUpload(); try { upload.uploadfile("192.168.0.210","muruganp","vm4snk","/home/media/Desktop/FTP Upload/data.doc","/fileserver/filesbackup/Emac/"); } catch (Exception e) { e.printStackTrace(); } } } 

我使用上面的代码在服务器位置192.168.0.210上传一个名为“data.doc”的文件。 我的服务器的目标位置是fileserver / filesbackup / Emac /。

但我最终收到错误“553无法创建文件”，虽然服务器已成功连接。 我怀疑我以错误的方式提供目标格式。 请让我知道要解决这个问题需要做些什么？

Answer 1

问题是您尝试将文件上载到目录。 您应该指定目标文件名 ，而不是目标目录 。

当您在另一个FTP客户端中尝试相同时它是否有效？

这里有一些（未经测试，因为我没有FTP服务器）代码可以更好地以更短的forms进行error handling。
