Google apps script 在收到新邮件时运行Gmail脚本

我正试图写一个脚本，将邮件从我的工作gmail转发到个人电子邮件。脚本只需要从周一到周五，下午4点到早上7点之间运行。我陷入困境的地方是在这段时间内每5分钟运行一次脚本，并且只转发新邮件

他们是否有谷歌脚本api来对收到的邮件执行操作（OnReceive）？或者我正在考虑添加一个自定义标签和一些if语句，以确保不转发重复的内容

下面是我现在要讲的泛型

function startCustomTrigger()
{
  ScriptApp.newTrigger('nonWorkHours').timeBased().everyMinutes(5).create();
}

function nonWorkHours() {

 var date = new Date();
 var day = date.getDay();
 var hrs = date.getHours();

if ((day >= 1) && (day <= 5) && (hrs >= 16) && (hrs <= 7)) {

   // forward email here
   var thread = GmailApp.getInboxThreads(0,1)[0]; // get first thread in inbox
   var message = thread.getMessages()[0]; // get first message
   message.forward("example@example.com");
 }

}

函数startCustomTrigger（）
{
ScriptApp.newTrigger（'nonWorkHours'）.timeBased（）.everyMinutes（5.create（）；
}
函数非工作时间（）{
变量日期=新日期（）；
var day=date.getDay（）；
var hrs=date.getHours（）；
如果（（天>=1）和（&（天=16）和（&）（小时）与以下记录行合并
Logger.log（“开始运行：“+Utilities.formatDate（新日期（startTime），Session.getScriptTimeZone（），'d MMM yy hh:mm:ss”）；//将时间记录为可读格式
//抓取gmail收件箱
var thread=GmailApp.search（'is:unread'）；//抓取所有未读消息
var gmailMessages=GmailApp.getMessagesForThreads（thread）；//获取上面设置的给定线程的所有消息
//设置脚本时间戳属性
var lastForwardTime=scriptProperties.getProperties（）；//上次运行scirpt时最后一条消息的时间戳的var
var keys=scriptProperties.getProperty（'lastForward'）；//来自lastForward时间戳的键
log（“转发消息的最后时间戳：“+keys）//将密钥记录到记录器
Logger.log（“label:+GmailApp.createLabel（“转发（非小时）”）；//创建标签，如果存在，将覆盖
//变量，用于将标签“转发（非小时）”设置为正在转发的线程
var label=GmailApp.getUserLabelByName（“转发（非小时）”；
//设置一些时间格式，检查M-F和下午4点到上午7点之间
变量日期=新日期（）；
var day=date.getDay（）；
Logger.log（天）；
var hrs=date.getHours（）；
Logger.log（小时）；
//=========================================================================================================================
如果（hrs>=16&&hrs=1&&hrs=1）&（day=6）&（day你有一个好的开始。为了不转发重复项，你可以使用标签，但在这种情况下，它是多余的

相反，请记住（在脚本属性服务中）转发的最后一封电子邮件的时间戳。然后使用搜索仅查找“之后”的电子邮件

如果在发送电子邮件后保存该属性，您将永远不会错过电子邮件，但如果sendmail呼叫在发送后立即崩溃，则很少会发送重复的电子邮件。
如果您在发送邮件之前保存了所有权，则可以保证没有重复项，但如果在发送电子邮件之前崩溃，则可能会丢失一些

查看文档和其他s.o.问题，了解如何在“日期之后”进行搜索。我已经对日期进行了搜索，但没有对日期时间进行搜索。如果只支持日期，您可能需要跳过一些结果或找到更有效的搜索方法

在电子邮件序列没有模式的一般情况下，使用标签是好的。在您的情况下，新收件箱邮件总是连续的。
不幸的是，没有onReceive触发器。您是否考虑过检查接收时间是否在过去5分钟内？
/**

Also mark the messages that are forwarded with custom label "Forwarded(Non_Hours)" and marked as read.
