如何防止gmail线程回来

Question

我有这个功能，我每小时运行一次。它会检查收件箱中是否有发往邮件列表的消息。然后它会重新格式化它们，保存附件，并将它们转发到另一个电子邮件地址，然后表面上丢弃处理过的邮件。效果很好，除了....

我最近遇到了一个不会死的线程。它有超过 50 条回复，当新回复带有相同主题行时，线程中所有已处理的旧消息都会再次处理。所以我的发件箱呈指数增长，收件人的电子邮件收件箱也是如此。我不确定我是否只是没有有效地删除已发送的消息，或者是否有其他方法我应该在线程中识别已处理的消息，以便在将更多消息添加到线程时不会再次处理它们.我不知道这是应用程序脚本问题还是 gmail 问题。

这是我的代码：

function processPMFMail(){
  var threads = GmailApp.getInboxThreads();
  var message = GmailApp.getMessagesForThreads(threads); 
  for(var i = 0; i < message.length; i++) {
    for(var j = 0; j < message[i].length; j++) {
      var from = message[i][j].getFrom();
      var to = message[i][j].getTo();
      var cc = message[i][j].getCc();
      var bcc = message[i][j].getBcc();
      var fields = {to, cc, bcc};
                    //Logger.log(to);

                    if (
                    [to,cc,bcc].some(field =>
                    ["EMAIL-1","EMAIL-2"].some(email => field.includes(email))
                    )
                    ) {
                    var subject = cleanSubject(message[i][j]);
                    if (subject == "DoNotPost") {
                    Logger.log("Email not for posting - " + cleanSubject(message[i][j]));
                    message[i][j].moveToTrash();
                   } else{
                    var from = parseEmailName(message[i][j]);
                    var body = message[i][j].getPlainBody();
                    var hBody = message[i][j].getBody();
                    var attachment = saveAttachments(message[i][j]);
                    var opening = "<br>From: " + from + "<br> Sent: "+ Utilities.formatDate(message[i][j].getDate(), "US/Eastern", "M/d/yy @ h:mm aaa") + "<br><br>" + attachment;
                    if (hBody.indexOf("</body>")>-1) {
                    hBody = removeForwards (hBody);
                    hBody = hBody.replace("</body>",opening + "</body>").trim();
                   } else{
                    hBody = hBody + opening;
                   }
                    Logger.log(subject + opening);
                    //send the message
                    GmailApp.sendEmail("EMAIL-3", subject , opening + body , 
                    {htmlBody: hBody, 
                    name: from
                   })  
    }  // end of processed messages
    //move the message to the trash
    message[i][j].moveToTrash();
  } 
  else {Logger.log("No Messages to forward")}
}
}

}

感谢任何指点。

因此，如果我理解正确，您会一遍又一遍地从一个线程中获取所有消息。

但最终这是意料之中的，因为您首先获得GmailThread，然后检查线程中的每个GmailMessage。即使您已经检查并删除了它，它也是线程的一部分，并且在使用getMessagesForThreads() 时将其取回是正常的。

我建议在每条消息（在 for 嵌套循环内）中使用 isInTrash()，以检查您是否已将此消息移至垃圾箱。

类似这样的：

function processPMFMail() {
    var threads = GmailApp.getInboxThreads();
    var message = GmailApp.getMessagesForThreads(threads);
    for (var i = 0; i < message.length; i++) {
        for (var j = 0; j < message[i].length; j++) {
            if (!message[i][j].isInTrash()) {
                var from = message[i][j].getFrom();
                var to = message[i][j].getTo();
                var cc = message[i][j].getCc();
                var bcc = message[i][j].getBcc();
                var from = message[i][j].getFrom();
                var fields = { to, cc, bcc };
                //Logger.log(to);

                if (
                    [to, cc, bcc].some(field =>
                        ["EMAIL-1", "EMAIL-2"].some(email => field.includes(email))
                    )
                ) {
                    var subject = cleanSubject(message[i][j]);
                    if (subject == "DoNotPost") {
                        Logger.log("Email not for posting - " + cleanSubject(message[i][j]));
                        message[i][j].moveToTrash();
                    } else {
                        var from = parseEmailName(message[i][j]);
                        var body = message[i][j].getPlainBody();
                        var hBody = message[i][j].getBody();
                        var attachment = saveAttachments(message[i][j]);
                        var opening = "<br>From: " + from + "<br> Sent: " + Utilities.formatDate(message[i][j].getDate(), "US/Eastern", "M/d/yy @ h:mm aaa") + "<br><br>" + attachment;
                        if (hBody.indexOf("</body>") > -1) {
                            hBody = removeForwards(hBody);
                            hBody = hBody.replace("</body>", opening + "</body>").trim();
                        } else {
                            hBody = hBody + opening;
                        }
                        Logger.log(subject + opening);
                        //send the message
                        GmailApp.sendEmail("EMAIL-3", subject, opening + body,
                            {
                                htmlBody: hBody,
                                name: from
                            })
                    }  // end of processed messages
                    //move the message to the trash
                    message[i][j].moveToTrash();
                }
                else { Logger.log("No Messages to forward") }
            }
        }
    }
