Hi!
This script send the message but does not include the attachement. I'm
struggling with the create_message_with_attachment function .
I did read google documentation. The stack threads talking about it focus
on complex issue (while mixing up on the top of it different syntax of
python version). Posting this in stack will be down-voted as duplicated
(stack has its limit).
Thanks in advance for your help!
Here is the faulty function (full code bellow)
def create_message_with_attachment(sender, to, subject, msgHtml, msgPlain):
# multipart container can contain other MIME parts. (attachment will be
independent of the multipart/alternative)
msg = MIMEMultipart('alternative')
msg['To'] = to
msg['From'] = sender
msg['Subject'] = subject
# convert both part to a MIME compatible string
part1 = MIMEText(msgPlain, 'plain')
part2 = MIMEText(msgHtml, 'html')
# create .txt attachment
filename=r"C:\Users\xxx\Desktop\test_Attachment.txt"
fp=open(filename).read()
att = MIMEApplication(fp)
fp.close()
#This will add a header that looks like: "Content-Disposition: attachment;
filename="test_Attachment.txt" "
att.add_header('content-disposition', 'attachment', filename = ('utf-8', ''
, 'test_Attachment.txt'))
# Attach parts into message container.
msg.attach(att)
msg.attach(part1)
msg.attach(part2)
raw = base64.urlsafe_b64encode(msg.as_bytes())
# raw= encoders.encode_base64(msg)
raw = raw.decode()
body = {'raw': raw}
return body
