确认后，将附有PDF的邮件发送给收件人

Question

我必须每天编辑一个Google电子表格文件。当我结束时，我想向人们发送信息，通知他们我已经完成了。附在该通知邮件后，我想向他们发送一份特定的表格（称为报告），作为PDF格式。

我找到了这个发送电子邮件的选项（并且工作正常）：

function sendEmails() {
var sheet = SpreadsheetApp.getActiveSheet();
var startRow = 2;  // First row of data to process
var numRows = 2;   // Number of rows to process
// Fetch the range of cells A2:B3
var dataRange = sheet.getRange(startRow, 1, numRows, 2)
// Fetch values for each row in the Range.
var data = dataRange.getValues();
for (i in data) {
var row = data[i];
var emailAddress = row[0];  // First column
var message = row[1];       // Second column
var subject = "Sending emails from a Spreadsheet";
MailApp.sendEmail(emailAddress, subject, message);
}
}

有没有办法将特定工作表添加为PDF？

第二个问题：如何在电子表格中创建某种按钮（“立即发送”），让我轻松发送此电子邮件，因此我不必每次都打开脚本编辑器？

菜单驱动的按需操作

在Google表格用户界面中，菜单项是将其设置为按需运行的一种自然方式。 ¹ 学习如何自行完成此操作的一个很好的资源是Google＆＃ 39; s Quickstart: Macros, Menus, and Custom Functions。

从该教程开始，这里将添加一个＆＃34;发送报告＆＃34;电子表格中的菜单项，选中后会调用sendReport_()函数：

/**
 * A special function that runs when the spreadsheet is open, used to add a
 * custom menu to the spreadsheet.
 */
function onOpen() {
  var spreadsheet = SpreadsheetApp.getActive();
  var menuItems = [
    {name: 'Send Report', functionName: 'sendReport_'}
  ];
  spreadsheet.addMenu('Custom', menuItems);
}

sendReport_()功能

假设我们有一个getPdfBlob()函数，它将返回一个适合附加到电子邮件的blob。有了这个，这里有sendReport_()所有需要做的事情：

// From https://stackoverflow.com/a/37149036/1677912
function sendReport_() {

  // Configuration parameters; customize as you wish
  var sheetName = "Report";
  var subject = "Email subject line";
  var recipients = "user1@example.com, user2@example.com";
  var htmlMessage = "Greetings,<br/><br/>"
                  + "Please find today's report attached as a PDF.<br/><br/>"
                  + "Cheers,<br/><br/>Paranoia";

  // Get the IDs of the spreadsheet & sheet-of-interest
  var ss = SpreadsheetApp.getActive();
  var sheetId = ss.getSheetByName(sheetName).getSheetId();

  // Retrieve the PDF blob
  var pdfBlobArray = getPdfBlobs(ss.getId(),sheetId);

  // Send the email + attachment
  MailApp.sendEmail(recipients,subject,"Report attached.", {
    htmlBody: htmlMessage,
    attachments: pdfBlobArray
  });
}

getPdfBlobs()效用函数

生成电子表格PDF的实用程序显示在Convert all sheets to PDF with Google Apps Script中。 这可以适用于返回包含您之后单张的PDF的blob。

您必须启用Advanced Drive Service至＆＃34;资源＆gt;高级驱动器服务......＆＃34;和开发人员控制台。 （有关详细信息，请参阅this。）

注意：通过编辑此功能中嵌入的网址参数，可支持PDF格式的自定义设置。

    var options = {
      headers: {
        'Authorization': 'Bearer ' +  ScriptApp.getOAuthToken()
      }
    }

    var response = UrlFetchApp.fetch(url + url_ext, options);

    var blob = response.getBlob().setName(ss.getName() + ' - ' + sheet.getName() + '.pdf');

    // Add blob to our array
    blobArray.push(blob);

  // Return array of PDF blobs
  return blobArray;

¹ 这可以进一步扩展为附加组件，因此不需要将脚本附加到特定的电子表格。
