FtpList部分是用來(lái)顯示FTP服務(wù)器上的文件;
GetButton部分為從FTP服務(wù)器下傳一個(gè)文件;
PutButton部分為向FTP服務(wù)器上傳一個(gè)文件。
別忘了在程序中還要引入兩個(gè)庫(kù)文件(import sun.net.*，import sun.net.ftp.*)。
以下是這三部分的JAVA源程序：
(1)顯示FTP服務(wù)器上的文件
void ftpList_actionPerformed(ActionEvent e) {
String server=serverEdit.getText();
//輸入的FTP服務(wù)器的IP地址
String user=userEdit.getText();
//登錄FTP服務(wù)器的用戶名
String password=passwordEdit.getText();
//登錄FTP服務(wù)器的用戶名的口令
String path=pathEdit.getText();
//FTP服務(wù)器上的路徑
try {
FtpClient ftpClient=new FtpClient();
//創(chuàng)建FtpClient對(duì)象
ftpClient.openServer(server);
//連接FTP服務(wù)器
ftpClient.login(user, password);
//登錄FTP服務(wù)器
if (path.length()!=0) ftpClient.cd(path); TelnetInputStream is=ftpClient.list(); int c; while ((c=is.read())!=-1) { System.out.print((char) c);} is.close(); ftpClient.closeServer();//退出FTP服務(wù)器 } catch (IOException ex) {;} } |
(2)從FTP服務(wù)器上下傳一個(gè)文件
void getButton_actionPerformed(ActionEvent e) { String server=serverEdit.getText(); String user=userEdit.getText(); String password=passwordEdit.getText(); String path=pathEdit.getText(); String filename=filenameEdit.getText(); try { FtpClient ftpClient=new FtpClient(); ftpClient.openServer(server); ftpClient.login(user, password); if (path.length()!=0) ftpClient.cd(path); ftpClient.binary(); TelnetInputStream is=ftpClient.get(filename); File file_out=new File(filename); FileOutputStream os=new FileOutputStream(file_out); byte[] bytes=new byte[1024]; int c; while ((c=is.read(bytes))!=-1) { os.write(bytes,0,c); } is.close(); os.close(); ftpClient.closeServer(); } catch (IOException ex) {;} } |
(3)向FTP服務(wù)器上上傳一個(gè)文件
void putButton_actionPerformed(ActionEvent e) { String server=serverEdit.getText(); String user=userEdit.getText(); String password=passwordEdit.getText(); String path=pathEdit.getText(); String filename=filenameEdit.getText(); try { FtpClient ftpClient=new FtpClient(); ftpClient.openServer(server); ftpClient.login(user, password); if (path.length()!=0) ftpClient.cd(path); ftpClient.binary(); TelnetOutputStream os=ftpClient.put(filename); File file_in=new File(filename); FileInputStream is=new FileInputStream(file_in); byte[] bytes=new byte[1024]; int c; while ((c=is.read(bytes))!=-1){ os.write(bytes,0,c);} is.close(); os.close(); ftpClient.closeServer(); } catch (IOException ex) {;} } } |
