Nodejs中读取中文文件编码问题、发送邮件和定时

npm install -g nodemailer

npm install -g node-schedule

var fileStr = fs.readFileSync('D:\\test.csv', {encoding:'binary'});
var buf = new Buffer(fileStr, 'binary');
var str = iconv.decode(buf, 'GBK');

console.log(str);

//配置邮件
var transporter = nodemailer.createTransport('SMTP',{
    service: '163qiye',
    auth: {
        user: 'zhoujie0111@126.',
        pass: '123456',
    }
});

//发送邮件
var sendmail = function(html){
    var option = {
            from:"zhoujie0111@126.",
            to:"zhoujie0111@126.,zhoujie0111@126.",
            :'zhoujie0111@126.'
        }
    option.subject = '我5年前制定的五年计划'
    option.html= html;
    transporter.sendMail(option, function(error, response){
        if(error){
            console.log("fail: " + error);
        }else{
            console.log("suess: " + response.message);
        }
    });
}

//调用发送邮件
sendmail("邮件内容<br/>My goal for 2015 is to acplish the goals of 2014 which I should have done in 2013 because I made a promise in 2012 & planned in 2011！");

/方式一
    指定某一个时间执行任务
/
var schedule = require('node-schedule');
var date = new Date(2014, 12, 31, 16, 1, 0);

var j = schedule.scheduleJob(date, function(){
    console.log('2015 will soon e.');
});

/方式二
    在每个小时的多少分钟执行
/
var rule = new schedule.RecurrenceRule();
rule.minute = 1;
var j = schedule.scheduleJob(rule, function(){
    console.log('I\'m very happy now!');
});

/方式三
    类似crontab
/
var j = schedule.scheduleJob('1 ', function(){
    console.log('It\'s time to 下午茶!');
});
