java - 如何通过 Telnet 发送字符串？

Question

我想使用 Apache 的 TelnetConnection 向 Telnet 连接发送字符串

import java.io.IOException;
import org.apache.commons.net.telnet.TelnetClient;

public class TestClass {
   public static void main(String[] args) throws IOException, InterruptedException {

        String telnetServer = "123.456.789.123";
        int telnetPort = 32106;
        TelnetClient telnet = new TelnetClient();
        try {
            telnet.connect(telnetServer, telnetPort);
            String start = "start";
            telnet.getOutputStream().write(start.getBytes());
            telnet.getOutputStream().flush();

            System.out.println(telnet.getInputStream());


        } catch (Exception e) {
            System.out.println(e);
        }finally {
            telnet.disconnect();
        }
    }
}

但是，我没有得到结果。在这种情况下如何使用输入和输出流？命令(“start”)应开始 METUS INGEST 5.6 的记录。

感谢一些程序员(https://stackoverflow.com/users/440558/some-programmer-dude)。这完全完成了工作。

完整代码如下:

import java.io.IOException;
import org.apache.commons.net.telnet.TelnetClient;

public class TestClass {
   public static void main(String[] args) throws IOException, InterruptedException {

        String telnetServer = "123.456.789.123";
        int telnetPort = 32106;
        TelnetClient telnet = new TelnetClient();
        try {
            telnet.connect(telnetServer, telnetPort);
            String start = "start\r\n";
            telnet.getOutputStream().write(start.getBytes());
            telnet.getOutputStream().flush();

            System.out.println(telnet.getInputStream());


        } catch (Exception e) {
            System.out.println(e);
        }finally {
            telnet.disconnect();
        }
    }
}

您可以通过以下方式停止所有源的录制:

String stop = "stop\r\n";
telnet.getOutputStream().write(stop.getBytes());
telnet.getOutputStream().flush();
