我想先连接到 aws 并通过 Api 从 Nodejs 中点击 python 命令。不知道该怎么做？

Question

我想从 nodejs.The 执行 'python3 sample.py --path.data=/root/tej4' 命令下面是我的代码 -

const runningPython = async(req,res,next) => {
    ssh.connect({
        host: '******',
        port: 22,
        username: 'ubuntu',
        privateKey: '*******'
    }).then(function () {
     exec('python3 sample.py --path.data=/root/tej4', (err, stdout, stderr) => {
        if (err) {
          console.log(err)
        }
      
        // the *entire* stdout and stderr (buffered)
        console.log(`stdout: ${stdout}`);
        console.log(`stderr: ${stderr}`);
      });
    })
    }

但我得到的回应是它试图运行在本地而不是在 aws cli 上。不确定如何实现？

Answer 1

您必须创建类型 node_ssh 的实例并使用该实例调用 connect 和 executeCommand 方法

const node_ssh = require('node-ssh');
const ssh = new node_ssh();

ssh
  .connect({
        host: '******',
        port: 22,
        username: 'ubuntu',
        privateKey: '*******'
  })
  .then(() => {
    ssh.execCommand('python3 sample.py --path.data=/root/tej4', { cwd:'/your-python-script-path-here' })
       .then((result) => {
          console.log('STDOUT: ' + result.stdout)
          console.log('STDERR: ' + result.stderr)
       });

您可以使用 ssh 库，但对于 sudo su 和运行多个命令切换到 ssh2shell，其代码如下所述：

const runningPython = async (req, res, next) => {
  var host = {
    server: {
      host: ***** ,
      username: ***** ,
      privateKey: fs.readFileSync('ppk file path'),
    },
    commands: ["sudo su -", "python3 sample.py --path.data=root/tej4"],
    onCommandComplete: function (command, response, sshObj) {
      if (sshObj.debug) {
        this.emit("msg", this.sshObj.server.host + ": host.onCommandComplete event, command: " + command);
      }
      if (command === "sudo su -" && response.indexOf("/root") != -1) {

        sshObj.commands.unshift("msg:The command and response check worked. Added another cd command.");
        sshObj.commands.unshift("cd .ssh");
      } else if (command === "python3 sample.py --path.data=root/tej4") {
        this.emit("msg", response);

      }
    },

    onEnd: function (sessionText, sshObj) {

      if (sshObj.debug) {
        this.emit("msg", this.sshObj.server.host + ": host.onEnd event");
      }
    }
  };

  let SSH = new SSH2Shell(host),
    //Use a callback function to process the full session text
    callback = function (sessionText) {
      console.log(sessionText)
    }

  //Start the process
  SSH.connect(callback);

}

I want to first connect to aws and hit a python command from Nodejs via Api. Not sure how to do?
