如何仅从 Google Apps 脚本中的 getDate() 获取时间？

Question

我正在尝试在 Google Apps Script 中创建一个基于时间的过滤器，以在一天中的特定时间过滤掉来自我的 gmail 帐户的具有特定主题行的邮件，并将标签应用于这些邮件。
到目前为止，我已经按主题行隔离了邮件，现在我想使用时间进一步隔离它们。 到目前为止，这是我的代码：

function xyz_filter() {
  var sent_threads = GmailApp.search('subject:xyz');
  Logger.log(sent_threads.length);
  for (var i = 0; i < sent_threads.length; i++) {
    var message = sent_threads[i].getMessages()[0];
    var recipient = message.getDate();
    Logger.log(recipient);
  }
}

我对 Google Apps Script 还很陌生，在过去的几个小时里，我一直在寻找类似用例的stackoverflow 。
我的代码主要取自这个链接： GMailApp Gmail 搜索

这是日志的输出：

请提出一种仅从该输出中获取时间的方法。

Answer 1

您是否尝试过使用： recipient.getHours(); recipient.getMinutes(); recipient.getSeconds(); recipient.getHours(); recipient.getMinutes(); recipient.getSeconds(); 收件者需要几个小时，几分钟和几秒钟的时间。

在这里，您将找到有关如何使用它的更多信息https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date 。 我希望能有所帮助，问候。

Answer 2

尝试 :recipient.toTimeString() 这会给你“00:01:48 GMT+05:30”，下面的代码将有助于获得像“00:01:48”这样的时间

function CreatTimestring(str1,pos){
    var str2='';
    for (var i=0;i<pos-1;i++){
      str2+=str1[i];
    }
    return str2;
  }
TimeStr = CreatTimestring(recipient.toTimeString(),recipient.toTimeString().indexOf('G',0));

希望这会帮助其他人..
