关于nodejs的几个干货（读中文文件编码问题/发送邮件/定时任务）

var iconv = require('iconv-lite');
var fs = require('fs');

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

console.log(str);

var nodemailer = require('nodemailer');

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

//发送邮件
var sendmail = function(html){
    var option = {
            from:"zhoujie0111@126.com",
            to:"zhoujie0111@126.com,zhoujie0111@126.com", 
            cc:'zhoujie0111@126.com'
        }
    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("success: " + response.message);
        }
    });
}

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

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

/*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 come.');
});

/*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!');
});
