Google Apps Script - send pdf in email

问题

I have a script that sends an email. I would like to set it up so that the email is sent with a pdf attachment that is in my google drive. The name of the file is pdfholder.pdf

Here is the code that is currently working (without attachment), and sending emails

MailApp.sendEmail(userEmail, subject, message);

Here is the code that is not working (with the attachment), and not sending emails

var file = DocsList.getFileById('pdfholder');
MailApp.sendEmail(userEmail, subject, message, {attachments:file});

Any ideas on how to get this working? I am new to google apps scripting so simple/thorough explanations would be much appreciated. Thanks!

回答1:

The argument needed for the optional argument attachment is an array (as clearly shown in the documentation). This is to allow for easy handling of multiple attached files. In you case it will be an array of one single element : [file] so your final code would (indeed) be

MailApp.sendEmail(userEmail, subject, message, {attachments:[file]});

The official doc has an example exactly for this purpose too:

// Send an email with two attachments: a file from Google Drive (as a PDF) and an HTML file.
 var file = DriveApp.getFileById('1234567890abcdefghijklmnopqrstuvwxyz');
 var blob = Utilities.newBlob('Insert any HTML content here', 'text/html', 'my_document.html');
 MailApp.sendEmail('mike@example.com', 'Attachment example', 'Two files are attached.', {
     name: 'Automatic Emailer Script',
     attachments: [file.getAs(MimeType.PDF), blob]
 });
