Hi there,
Using Python 3.1.2 I am having a problem sending binary attachment files
(jpeg, pdf, etc.) - MIMEText attachments work fine. The code in question
is as follows...
for file in self.attachments:
part = MIMEBase('application', "octet-stream")
part.set_payload(open(file,"rb").read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', 'attachment; filename="%s"' %
file)
msg.attach(part) # msg is an instance of MIMEMultipart()
server = smtplib.SMTP(host, port)
server.login(username, password)
server.sendmail(from_addr, all_recipients, msg.as_string())
However, way down in the calling-stack (see traceback below), it looks
as though msg.as_string() has received an attachment which creates a
payload of 'bytes' type instead of string. I suspect the error lies in
the encoding somewhere, but I've no idea where. I have also tried
MIMEApplication and MIMEImage, but the error still remains. I have seen
many similar code examples on the web, all of which fail for me, so I
wonder if there is something wrong with my environment.
Has anyone any idea what might be causing the problem? Any help would be
appreciated.
Alan
