如何使用 sshj java api 通过用户名和密码连接到远程计算机？

我尝试了这段代码。这段代码有什么问题？

final SSHClient ssh = new SSHClient();
        ssh.connect("192.168.0.1");
        ssh.authPassword("abcde", "fgh".toCharArray());
        try {
            final Session session = ssh.startSession();
            try {
                final Command cmd = session
                        .exec("cd /home/abcde/Desktop/");
                System.out.println(IOUtils.readFully(cmd.getInputStream())
                        .toString());
                cmd.join(5, TimeUnit.SECONDS);
                System.out.println("\n** exit status: " + cmd.getExitStatus());
            } finally {
                session.close();
            }
        } finally {
            ssh.disconnect();
        }

它抛出以下错误。

net.schmizz.sshj.transport.TransportException: [HOST_KEY_NOT_VERIFIABLE] Could not verify ssh-rsa host key with fingerprint ******** for 192.168.0.1 on port 22

您可以通过实现 HostKeyVerifier 来解决您的问题

class NullHostKeyVerifier implements HostKeyVerifier {
    @Override
    public boolean verify(String arg0, int arg1, PublicKey arg2) {
        return true;
    }        
}

并将这个假实现添加到您的 SSHClient 实例配置中:

...
    final SSHClient ssh = new SSHClient();
    ssh.addHostKeyVerifier(new NullHostKeyVerifier());
...
