[英]List all files in remote server using JSch
I am trying to list all the files/directory from a remote server using JSch.我正在尝试使用 JSch 列出来自远程服务器的所有文件/目录。
But my problem is JSch list all the files with file creation date, time stamp, type of read/write permission etc..,但我的问题是 JSch 列出了所有文件,包括文件创建日期、时间戳、读/写权限类型等,
But in my case I need only the file/directory name in the remote server and no additional information is required..但在我的情况下,我只需要远程服务器中的文件/目录名称,不需要其他信息..
Below is my piece of Java code..下面是我的一段Java代码..
import java.util.Vector;
import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
public class Listremoteserver {
@SuppressWarnings("unchecked")
public static void main(String[] args) {
String SFTPHOST = "xxxxx";
int SFTPPORT = 22;
String SFTPUSER = "xxx";
String SFTPPASS = "xxxxx";
String SFTPWORKINGDIR = "/root";
Session session = null;
Channel channel = null;
ChannelSftp channelSftp = null;
try{
JSch jsch = new JSch();
session = jsch.getSession(SFTPUSER,SFTPHOST,SFTPPORT);
session.setPassword(SFTPPASS);
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect();
channel = session.openChannel("sftp");
channel.connect();
channelSftp = (ChannelSftp)channel;
channelSftp.cd(SFTPWORKINGDIR);
Vector filelist = channelSftp.ls(SFTPWORKINGDIR);
for(int i=0; i<filelist.size();i++){
System.out.println(filelist.get(i).toString());
}
}catch(Exception ex){
ex.printStackTrace();
}
}
}
Results of the above program is上述程序的结果是

Try running this code.尝试运行此代码。 Here we are typecasting the list elements to LsEntry and then printing the required attribute.
这里我们将列表元素类型转换为 LsEntry,然后打印所需的属性。
import java.io.File;

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.ChannelSftp.LsEntry;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
public class Listremoteserver {
/**

@SuppressWarnings("unchecked")
public static void main(String[] args) {
String SFTPHOST = "xxxxx";
int SFTPPORT = 22;
String SFTPUSER = "xxx";
String SFTPPASS = "xxxxx";
String SFTPWORKINGDIR = "/tmp";
String SFTPPRIVATEKEY = "/path/to/xxxxxxxxx.pem";
Session session = null;
Channel channel = null;
ChannelSftp channelSftp = null;
try{
JSch jsch = new JSch();
File privateKey = new File(SFTPPRIVATEKEY);
if(privateKey.exists() && privateKey.isFile())
jsch.addIdentity(SFTPPRIVATEKEY);
session = jsch.getSession(SFTPUSER,SFTPHOST,SFTPPORT);
session.setPassword(SFTPPASS);
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect();
channel = session.openChannel("sftp");
channel.connect();
channelSftp = (ChannelSftp)channel;
channelSftp.cd(SFTPWORKINGDIR);
Vector filelist = channelSftp.ls(SFTPWORKINGDIR);
for(int i=0; i<filelist.size();i++){
LsEntry entry = (LsEntry) filelist.get(i);
System.out.println(entry.getFilename());
}
}catch(Exception ex){
ex.printStackTrace();
} finally {
if(session != null) session.disconnect();
if(channel != null) channel.disconnect();
}
}
}
Use LSEntrySelector for accessing the properties of returned file list.使用 LSEntrySelector 访问返回文件列表的属性。

for sftp
you can getlist of file with对于
sftp
您可以使用
Vector<ChannelSftp.LsEntry> list = channelSftp.ls("*.*");
for(ChannelSftp.LsEntry entry:list) {
System.out.println(entry.getFilename());
}
and there isn't built in function to get list file for exec
and shell
protocol, you have parse it from InputStream
data.并且没有内置函数来获取
exec
和shell
协议的列表文件,您已经从InputStream
数据解析它。
try to exec ls command :尝试执行 ls 命令:
Channel channel=session.openChannel("exec");
((ChannelExec)channel).setCommand("cd " + SFTPWORKINGDIR + " && ls");
channel.connect();
channel.run();
Vector filelist = channel.run();
for (int i = 0; i < filelist.size(); i++) {
System.out.println(filelist.get(i).toString());
}
