从 gmail 中保存附加的 PDF 文件，标题为主题名称

Question

要从 gmail 下载多个 PDF 文件，我使用以下脚本。它工作正常，我只需要更改一个细节。我需要下载的名称 PDF-File 作为邮件主题的名称。如果尝试修改它，但它不起作用：/有任何提示我必须更改哪一行以获得所需的输出吗？

function GmailToDrive(){
  //build query to search emails
  var query = '';
  //filename:jpg OR filename:tif OR filename:gif OR fileName:png OR filename:bmp OR filename:svg'; //'after:'+getDateNDaysBack_(1)+
  for(var i in fileTypesToExtract){
    query += (query === '' ?('filename:'+fileTypesToExtract[i]) : (' OR filename:'+fileTypesToExtract[i]));
  }
  query = 'label:inbox-Gesellschafter is:unread ' + query;
//  query += ' after:'+getDateNDaysBack_(1);
  var threads = GmailApp.search(query);
  var label = getGmailLabel_(labelName);
  var parentFolder;
  if(threads.length > 0){
    parentFolder = getFolder_(folderName);
  }
  var root = DriveApp.getRootFolder();
  for(var i in threads){
    var mesgs = threads[i].getMessages();
    for(var j in mesgs){
      //get attachments
      var attachments = mesgs[j].getAttachments();
      for(var k in attachments){
        var attachment = attachments[k];
//      var isDefinedType = checkIfDefinedType_(attachment);
//      if(!isDefinedType) continue;
        var attachmentBlob = attachment.copyBlob();
        var file = DriveApp.createFile(attachmentBlob);
        parentFolder.addFile(file);
        root.removeFile(file);
      }
    }
    threads[i].addLabel(label);
  }
}

//This function will get the parent folder in Google drive
function getFolder_(folderName){
  var folder;
  var fi = DriveApp.getFoldersByName(folderName);
  if(fi.hasNext()){
    folder = fi.next();
  }
  else{
    folder = DriveApp.createFolder(folderName);
  }
  return folder;
}

//getDate n days back
// n must be integer
function getDateNDaysBack_(n){
  n = parseInt(n);
  var date = new Date();
  date.setDate(date.getDate() - n);
  return Utilities.formatDate(date, Session.getScriptTimeZone(), 'yyyy/MM/dd');
}

function getGmailLabel_(name){
  var label = GmailApp.getUserLabelByName(name);
  if(!label){
    label = GmailApp.createLabel(name);
  }
  return label;
}

//this function will check for filextension type.
// and return boolean
function checkIfDefinedType_(attachment){
  var fileName = attachment.getName();
  var temp = fileName.split('.');
  var fileExtension = temp[temp.length-1].toLowerCase();
  if(fileTypesToExtract.indexOf(fileExtension) !== -1) return true;
  else return false;
}

当然，只需通过获取主题然后在现有代码中使用它来修改现有代码。

var attachments = mesgs[j].getAttachments();

// now also get the subject
var subject = mesgs[j].getSubject()

// now use the subject
 var file = DriveApp.createFile(attachmentBlob).setName(subject)
