nodejs調用linux指令

(1).調用curl指令:

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 {
        /*
        這個stdout的内容就是上面我curl出來的這個東西：
        {"weatherinfo":{"city":"北京","cityid":"101010100","temp":"3","WD":"西北風","WS":"3級","SD":"23%","WSE":"3","time":"21:20","isRadar":"1","Radar":"JC_RADAR_AZ9010_JB","njd":"暫無實況","qy":"1019"}}
        */
        var data = JSON.parse(stdout);
        console.log(data);
    }
});
           

(2).調用ls -l指令

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).調用一個shell腳本(注意：根據代碼，test.sh腳本檔案需要儲存在與nodejs同目錄下)

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