从Google表格发送电子邮件所需的协助脚本

Question

我有一个非常简单的脚本，该脚本根据一些变量从Google工作表发送电子邮件。

我想在电子邮件中添加默认的用户签名，但是我不知道该怎么做，我已阅读文章，建议使用：

  

var签名=   Gmail.Users.Settings.SendAs.list（“ me”）。sendAs.filter（function（account）{if（account.isDefault）{return   true}}）[0] .signature;

但是以上内容对我不起作用。

我的完整代码是：

/**
* Sends emails with data from the current spreadsheet.
*/
function sendEmails() {
    var sheet = SpreadsheetApp.getActiveSheet();
    var startRow = 3; // First row of data to process
    var numRows = sheet.getRange("H1").getValue(); // Number of rows to process and selects H1 as the range which is variable depending on selected

    // Fetch the range of cells A3:B300

    var dataRange = sheet.getRange(startRow, 1, numRows, 300);

    // Fetch values for each row in the Range.

    var data = dataRange.getValues();

    var signature = Gmail.Users.Settings.SendAs.list("me").sendAs.filter(function(account){if(account.isDefault){return true}})[0].signature;

    for (i in data) 

    var row = data[i];

    var emailAddress = row[0]; // First column

    var message = row[1]; // Second column

    var subject = sheet.getRange("K1").getValue(); // This Function selects the data in K1 as the email subject

    var body = message +" "+signature;

    MailApp.sendEmail(emailAddress, subject, body);
}
