automated-telnet-client/
您将需要修改提示变量。
代码副本：
import org.apache.commons.net.telnet.TelnetClient;import java.io.InputStream;import java.io.PrintStream;public class AutomatedTelnetClient { private TelnetClient telnet = new TelnetClient(); private InputStream in; private PrintStream out; private String prompt = "%"; public AutomatedTelnetClient(String server, String user, String password) { try { // Connect to the specified server telnet.connect(server, 23); // Get input and output stream references in = telnet.getInputStream(); out = new PrintStream(telnet.getOutputStream()); // Log the user on readUntil("login: "); write(user); readUntil("Password: "); write(password); // Advance to a prompt readUntil(prompt + " "); } catch (Exception e) { e.printStackTrace(); } } public void su(String password) { try { write("su"); readUntil("Password: "); write(password); prompt = "#"; readUntil(prompt + " "); } catch (Exception e) { e.printStackTrace(); } } public String readUntil(String pattern) { try { char lastChar = pattern.charAt(pattern.length() - 1); StringBuffer sb = new StringBuffer(); boolean found = false; char ch = (char) in.read(); while (true) { System.out.print(ch); sb.append(ch); if (ch == lastChar) { if (sb.toString().endsWith(pattern)) { return sb.toString(); } } ch = (char) in.read(); } } catch (Exception e) { e.printStackTrace(); } return null; } public void write(String value) { try { out.println(value); out.flush(); System.out.println(value); } catch (Exception e) { e.printStackTrace(); } } public String sendCommand(String command) { try { write(command); return readUntil(prompt + " "); } catch (Exception e) { e.printStackTrace(); } return null; } public void disconnect() { try { telnet.disconnect(); } catch (Exception e) { e.printStackTrace(); } } public static void main(String[] args) { try { AutomatedTelnetClient telnet = new AutomatedTelnetClient( "myserver", "userId", "Password"); System.out.println("Got Connection..."); telnet.sendCommand("ps -ef "); System.out.println("run command"); telnet.sendCommand("ls "); System.out.println("run command 2"); telnet.disconnect(); System.out.println("DONE"); } catch (Exception e) { e.printStackTrace(); } }}
