`executeRemoteCommand` 是 `JavaSSHd` 库中的一个方法,用于在远程服务器上执行命令。它的语法如下:
```java
public void executeRemoteCommand(String command) throws IOException
```
其中 `command` 参数是要在远程服务器上执行的命令。该方法会以当前用户的身份在远程服务器上执行该命令,并将命令的输出流返回给调用者。
以下是一个示例:
```java
import org.apache.sshd.client.SshClient;
import org.apache.sshd.client.channel.ChannelExec;
import org.apache.sshd.client.session.ClientSession;
import org.apache.sshd.common.util.io.NoCloseOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
public class SSHExample {
public static void main(String[] args) throws Exception {
String host = "example.com";
String username = "user";
String password = "password";
String command = "ls -l";
SshClient sshClient = SshClient.setUpDefaultClient();
sshClient.start();
ClientSession session = sshClient.connect(username, host, 22).verify().getSession();
session.addPasswordIdentity(password);
session.auth().verify();
ChannelExec channel = session.createExecChannel(command);
OutputStream out = NoCloseOutputStream.wrap(System.out);
channel.setOut(out);
InputStream in = channel.getInputStream();
channel.open();
byte[] buffer = new byte[1024];
while (true) {
int len = in.read(buffer);
if (len == -1) {
break;
}
out.write(buffer, 0, len);
}
channel.close();
session.close();
sshClient.stop();
}
}
```
该示例使用 `JavaSSHd` 库连接到远程服务器,并在远程服务器上执行 `ls -l` 命令。命令的输出被写入标准输出流。
