如何避免请求 OAuth API 验证以使用 Google 脚本发送电子邮件

Question

这个问题来自于上一个几乎解决的问题：

简介

也许这是一个技术问题，我不是程序员，所以如果可能的话，我想要一个循序渐进的答案，这样我才能完全理解它。

此处解释代码的步骤和用途：Hacking it: Generate PDFs from Google Forms。

代码是 post 在 link 上编辑的，但我还是 post 在这里：

function onSubmit(e) {
  const rg = e.range;
  const sh = rg.getSheet();
  
  //Get all the form submitted data
  //Note: This data is dependent on the headers. If headers, are changed update these as well.
  const cName = e.namedValues['Client Name'][0];
  const cEmail = e.namedValues['Client Email'][0];
  const cAddress = e.namedValues['Client Address'][0];
  const cMobile = e.namedValues['Client Mobile'][0];
  const sendCopy = e.namedValues['Send client a copy?'][0];
  const paymentType = e.namedValues['What is your agreed upon payment schedule?'][0];
  const fixedCost = e.namedValues['What was your agreed upon cost for the project?'][0];
  const hourlyRate = e.namedValues['Hourly Rate'][0];
  const manHours = e.namedValues['Total man hours'][0];
  const services = e.namedValues['Select the services'][0];
  
  //Consequential Data
  const tax = 18.5
  var subtotal = 0;
  var taxAmt = 0;
  var payableAmt = 0;
      
  //if the user has selected hourly payment model
  //Note: Be careful that the responses match the elements on the actual form
  switch (paymentType ){
    case 'Hourly Rate':
      subtotal = hourlyRate*manHours;
      taxAmt = subtotal * (tax/100);
      payableAmt = +subtotal + +taxAmt;
      break;
    case 'Fixed Cost':
      subtotal = fixedCost;
      taxAmt = fixedCost * (tax/100)
      payableAmt = +fixedCost + +taxAmt;
      break;            
  }
  
  const invoiceID = 'IN' + Math.random().toString().substr(2, 9);
  var formattedDate = Utilities.formatDate(new Date(), "IST", "dd-MMM-yyyy");
  
  //Set the consequential data in the columns of the spreadsheet for record keeping
  //Note: These variable are dependent on the sheet's columns so if that changes, please update.
  const row = rg.getRow();
  
  const payableAmtCol = 2; //B
  const invoiceIDCol = 3; //C
  
  sh.getRange(row,payableAmtCol).setValue(payableAmt);
  sh.getRange(row,invoiceIDCol).setValue(invoiceID); 
  
  
  //Build a new invoice from the file
  //Folder and file IDs
  const invoiceFolderID = '<invoice-folder-id>';
  const invoiceFolder = DriveApp.getFolderById(invoiceFolderID);
  
  const templateFileID = '<template-id>';
  const newFilename = 'Invoice_' + invoiceID;
  
  //Make a copy of the template file
  const newInvoiceFileID = DriveApp.getFileById(templateFileID).makeCopy(newFilename, invoiceFolder).getId();;
  
  //Get the invoice body into a variable
  var document = DocumentApp.openById(newInvoiceFileID);
  var body = document.getBody();
  
  //Replace all the {{ }} text in the invoice body
  body.replaceText('{{Invoice num}}', invoiceID);
  body.replaceText('{{Date}}', formattedDate);
  body.replaceText('{{Client Name}}', cName);
  body.replaceText('{{Client Address}}', cAddress);
  body.replaceText('{{Client Mobile}}', cMobile);
  body.replaceText('{{Client Email}}', cEmail);
  body.replaceText('{{Services}}', services.split(', ').join('\n'));
  
  body.replaceText('{{Subtotal}}', subtotal);
  body.replaceText('{{Tax Value}}', taxAmt);
  body.replaceText('{{Total}}', payableAmt);
  
  //In the case of hourly rate payment type, let's add an additional message giving the rate and the man hours.
  if(paymentType.includes('Hourly Rate')){
     //It should look something like this on the invoice
     //Hourly Rate
     //Rate of Rs.1200/hour
     //Completed 50 man hours
     const message = paymentType + '\nRate of Rs.' + hourlyRate + '/hour\nCompleted ' + manHours + ' man hours';
     body.replaceText('{{Payment Type}}', message);
  } else {
    body.replaceText('{{Payment Type}}', paymentType);
  }
  
  document.saveAndClose();
  
  /* This is not useful for me
  //If you have selected to directly send it via email
  if(sendCopy.includes('Yes')){
    //send email with the file
  var attachment = DriveApp.getFileById(newInvoiceFileID);
    GmailApp.sendEmail(cEmail, '<subject>, 
                     '<body>', 
                     {attachments: [attachment.getAs(MimeType.PDF)],
                      from:'<your-email>@gmail.com'});
  }
  */
  
}

在post中，作者展示了一种向客户端发送电子邮件的方法，这就是我想要的项目。

实际问题

但是，那部分代码已过时，或者作者在发布她的应用程序之前完成了验证过程，因为我必须根据 sendEmail 命令请求 OAuth API 验证。正如我所研究的那样，这需要我完全不知道的时间和工具（我不是程序员）。

因此，我问 是否有一种简单的方法（无需附加组件并避免请求验证过程）在客户按下“发送”时将生成的文档的副本发送给客户Google 表单的按钮基于我 posted.

的代码

该代码运行良好，它根据模板将文档副本创建到我的云端硬盘文件夹中，但我想自动发送电子邮件，以便客户获得我拥有的文档副本。我不想发送任何其他信息，例如垃圾邮件等

编辑这是我里面的内容 appsscript.json:

{
  "timeZone": "America/New_York",
  "dependencies": {
  },
  "exceptionLogging": "STACKDRIVER",
  "runtimeVersion": "V8"
}

这是我的一个 oauthscope 的样子：

"oauthScopes": [
    "https://mail.google.com/",
    "https://www.google.com/m8/feeds",
    "https://www.googleapis.com/auth/userinfo.email",
    "https://www.googleapis.com/auth/script.external_request",
    "https://www.googleapis.com/auth/spreadsheets",
