Question

我正在尝试在node.js中运行一个ssh子进程，并通过我的程序控制它。我的代码：

var util   = require('util');
var spawn = require('child_process').spawn;
var ssh    = spawn('ssh', ['cloudstudios.ch']);

ssh.stdout.on('data', function (data) {
  console.log('stdout: ' + data);
});

ssh.stderr.on('data', function (data) {
  console.log('stderr: ' + data);
});

ssh.on('exit', function (code) {
  console.log('child process exited with code ' + code);
});

我可以在控制台输入密码，但之后我什么也做不了。我得到以下控制台输出：

stderr: Pseudo-terminal will not be allocated because stdin is not a terminal.

root@xxxxxxxxxxxxx.xx's password:
stdout: Linux v 2.6.32-5-xen-amd64 #1 SMP Wed Jan 12 05:46:49 UTC 2011 x86_64

stderr: stdin: is not a tty

有人知道如何才能让它发挥作用吗？

谢谢！

Answer 1

尝试一点修改：

var ssh = spawn('ssh', ['-tt', 'xxx']);

和

process.stdin.resume();
process.stdin.on('data', function (chunk) {
  ssh.stdin.write(chunk);
});

我现在为node.js创建了一个SSHClient。您可以在https://github.com/VanCoding/NodeSSH下载源代码。

希望它会帮助其他人。
