Question

我在硬件上与控制台连接但它与命令一起工作：

我创建了omron.sh，因为我需要在nodeJS

中运行它

#!/bin/sh

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/splincode/Develop/omron/c++_modules/libomron/omron-build/lib/
~/Develop/omron/usr/local/bin/omron_790IT_test

但我需要它在NodeJS中工作并写入流stdout，但是，不工作

server.js：

let http = require('http'), 
    fs = require('fs'),
    url = require('url'),
    path = require('path');

let server = new http.Server(); // EventEmitter

server.listen(8000, '127.0.0.1');
server.on("connection", () => console.log("connection"));
server.on('request', (request, response) => {

    console.log('.', request.url)

    let userUrl = decodeURIComponent(url.parse(request.url).pathname);
    let loadFile = false;

    switch(userUrl) {
        case '/': 
            userUrl += 'index.html';
            loadFile = true;
        break;

        case '/omron':

            console.log('omron')

            var util=require('util')
            var exec=require('child_process').spawn('sh', ['omron.sh']);

            // not work
            exec.stdout.on('data', (data) => {
              console.log(`stdout: ${data}`);
              response.end(`${data}`);
            }); 

        break;

        default: 
            loadFile = true;
        break;
    };


    if (userUrl === '/') userUrl += 'index.html';


    if (loadFile) {
        let pathname = path.normalize(path.join(__dirname, userUrl));
        fs.readFile(pathname, (err, content) => {
            let mime = require('mime').lookup(pathname);
            response.setHeader('Content-Type', `${mime}; charset=utf-8`);
            response.end(content);
        });
    }


});

但是，不行，我需要给shell脚本一个响应输出流，但是怎么做？

节点-CMD

 Simple commandline/terminal interface to allow you to run cli or
     bash style commands as if you were in the terminal.

异步运行命令，如果需要，可以将输出作为字符串。

所以做这样的事情来解决你的问题

var cmd=require('node-cmd');

cmd.get(
    'pwd',
    function(data){
        console.log('the current working dir is : ',data)
    }
);

cmd.run('whoami');

如何在NodeJS中执行shell脚本并等待它显示并进入流中？
