节点js的ssh2中的客户端方法“exec”是否有同步等效项？

Question

I have connected to a remote machine using ssh2 in node js.
Now I want to run commands on the remote machine synchronously.

var Client = require('ssh2').Client;


var conn = new Client();
conn.on('ready', function() {
  console.log('Client :: ready');
  conn.exec('uptime', function(err, stream) {
    if (err) throw err;
    stream.on('close', function(code, signal) {
      console.log('Stream :: close :: code: ' + code + ', signal: ' + signal);
      conn.end();
    }).on('data', function(data) {
      console.log('STDOUT: ' + data);
    }).stderr.on('data', function(data) {
      console.log('STDERR: ' + data);
    });
  });
}).connect({
  host: '192.168.100.100',
  port: 22,
  username: 'frylock',
  privateKey: require('fs').readFileSync('/here/is/my/key')
});

This way i can execute it in an async way. If there any function equivalent to "exec" which is sync.

Use conn.shell instead of conn.exec. With shell method you can start an interactive shell session.

Here an example:
