使用Google Appscript - 如何使用位于Gmail中的草稿模板中的自定义正文发送自动电子邮件？

Question

I've got an simple automated email messaging api up and running. However, I want the "body" of the message to be something more complicated than just unformatted text. My code uses data from google sheets and is as follows:

function doGet(e)
{
  var ss = SpreadsheetApp.openById('SpreadsheetID');
  var sheet = ss.getSheetByName("msg");
  var rows = sheet.getDataRange().getValues();
  Logger.log(e.parameter.name);
  var headings = rows[0].map(String.toLowerCase);
  Logger.log(headings);
  var holder = [];
  for(x in headings)
  {
    Logger.log(headings[x]);
    var output = (headings[x] in e.parameters) ? e.parameter[headings[x]] : 'none';
    if (headings[x] == 'id'){ output = getRandom();}
    if (headings[x] == 'timestamp'){ output = new Date();}
    holder.push(output);
  }
  Logger.log("The holder contains the following: " + holder);
  Logger.log(holder.length);
  sheet.appendRow(holder);

  var lRow = sheet.getLastRow();

  Logger.log('HEADING IS: ' + headings[1] + ' ' + lRow + ' ' + sheet.getRange(lRow, 2).getValue());

  var tempMsg = GmailApp.getDraft()[0].getMessage();

  MailApp.sendEmail(sheet.getRange(lRow, 2).getValue(),'mo@example.co.uk', 'Thank you for signing up!!', tempMsg.getBody());

  return ContentService.createTextOutput(JSON.stringify({
    'status' : 'success',
    'lastRow' : lRow ,
    'INFO' : holder
  }))
}

With the above code, I tried emailing myself and do not get an email. If i delete the "var tempMsg..." and and replace the final property of MailApp.SendEmail (tempMsg.getBody()) to any string - it does work.

The idea is to use the body of a draft email in my Gmail drafts folder as the body of the new automated email.

I went through the api and tried different methods like GmailApp.getDraft(id).

Thank you for your help.

I've made some progress. I've managed to learn how to add html/css styling to the body of my email and it works. This doesn't answer the question exactly but the result is what i wanted.

var htmlmsg = "<h1 style='text-align: center;'>This is the heading</h1><br/><p>Body Text</p>"; MailApp.sendEmail(sheet.getRange(lRow, 2).getValue(), 'Thank you for signing up!!', htmlmsg, {htmlBody:htmlmsg});
