(1).调用curl命令:

var exec = require('child_process').exec;
var cmdStr = 'curl http://www.weather.com.cn/data/sk/101010100.html';
exec(cmdStr, function (err, stdout, stderr) {
    if (err) {
        console.log('get weather api error:' + stderr);
    } else {
        /*
        这个stdout的内容就是上面我curl出来的这个东西：
        {"weatherinfo":{"city":"北京","cityid":"101010100","temp":"3","WD":"西北风","WS":"3级","SD":"23%","WSE":"3","time":"21:20","isRadar":"1","Radar":"JC_RADAR_AZ9010_JB","njd":"暂无实况","qy":"1019"}}
        */
        var data = JSON.parse(stdout);
        console.log(data);
    }
});

(2).调用ls -l命令

var exec = require('child_process').exec;
var cmdStr = 'ls -l';
exec(cmdStr, function (err, stdout, srderr) {
    if (err) {
        console.log(srderr);
    } else {
        console.log(stdout);
    }
});

(3).调用一个shell脚本(注意：根据代码，test.sh脚本文件需要保存在与nodejs同目录下)

var exec = require('child_process').execFile;
exec('./test.sh', { encoding: 'utf8' }, function (err, stdout, stderr) {
    if (err) {
        console.log(err);
        return;
    }
    console.log(stdout)
});
