Mysql 节点js中的日程安排在日期

我想在NodeJS中创建调度器来调用服务并向特定请求发送电子邮件

发布日期=20/03/2017

计划时间为发布日期前2个月1个月15天。 我在下面尝试了这个，请为我提供更好的解决方案 函数checkRelease（）{

}

var计划=要求（“节点计划”）； var job=schedule.scheduleJob（{hour:10，minute:0}，function（））{ checkRelease（）；`此函数用于检查时间差和调用服务

列表项

` });

到目前为止您尝试了什么？调度程序每天调用一次，所以我需要检查当前日期并找到差异。函数checkRelease（）{var date='2017-11-18T07:05:32.950Z'；var release=new date（date）；console.log（release）；var current=new date（）；console.log（current）；var timeDifference=Math.abs（release.getTime（）-current.getTime（））；console.log（时差）；var differentitday=Math.ceil（时差/（1000*3600*24））；console.log（差日）；if（差日==1）{console.log（“1天”）}否则if（差日==28 | |差日==29 | |差日==30 |差日==31{console.log（“1个月”）}在发布您的问题之前，您似乎没有进行任何搜索。请参阅以提高您的问题的质量并对其进行编辑。请不要将示例代码放在注释中。请改为您的问题。

var date = '2017-11-18T07:05:32.950Z';
var release = new Date(date);
console.log(release);
var current = new Date();
console.log(current);
var timeDifference = Math.abs(release.getTime() - current.getTime());
console.log(timeDifference);
var differentDays = Math.ceil(timeDifference / (1000 * 3600 * 24));
console.log(differentDays);

if(differentDays === 1){
    console.log("1 day");
} else if(differentDays === 15){
    console.log("15 day");
} else if(differentDays === 28 || differentDays === 29 || differentDays === 30 || differentDays === 31){
    console.log("1 month");
} else if(differentDays === 58 || differentDays === 59 || differentDays === 60 || differentDays === 61 || differentDays === 62){        
    console.log("2 month");
}

relDate ="2017-11-21T20:58:00.000Z";
var current = new Date();
console.log(current);
var timeDifference = Math.abs(relDate.getTime() - current.getTime());
var differentDays = Math.ceil(timeDifference / (1000 * 3600 *24));
console.log(differentDays);
if(differentDays === 1){
console.log("1 day");
} else if(differentDays === 15){
console.log("15 day");
} else if(differentDays === 28 || differentDays === 29 || differentDays === 
30 || differentDays === 31){
console.log("1 month");
} else if(differentDays === 58 || differentDays === 59 || differentDays === 
60 || differentDays === 61 || differentDays === 62){                 
console.log("2 month");
}
**output**
1 day

i call this function inside scheduler in app.js

//---Sechduler for release and roration date
var job = schedule.scheduleJob({hour: 18, minute:54}, function(){
        checkRelease();`call function`

});
