getting a blank email | 易学教程

问题

I have quickly written below code to send data being sent to REST remote server for debuging but I am receiving blank email. now sure what is going wrong . in the terminal body dict text or json converted text is getting printed but getting nothing in email.

# For testing
def sendMail(usr, pwd, to, body):
    """ just for testing to send error via email
    """
    fromaddr = usr
    toaddr = to
    msg = MIMEMultipart()
    msg['From'] = fromaddr
    msg['To'] = toaddr
    msg['Subject'] = "Data add request"
    try:
        server = smtplib.SMTP('smtp.gmail.com', 587)
        server.ehlo()
        server.starttls()
        server.ehlo()
        server.login(usr, pwd)
        msg.attach(body)
        r = json.dumps(body)
        loaded_r = json.loads(r)
        print "json: ", str(loaded_r)
        server.sendmail("error-report@do_not_reply.com", to,  str(loaded_r))
    except Exception, err:
        print 'Error sending email: ', err
    finally:
        server.quit()

I tried sending server.sendmail("error-report@do_not_reply.com", to, body) but that too sends blank email without subject. what am I doing wrong ?

The message you pass as the third argument to sendmail needs to be a valid, properly formatted RFC822 message. A JSON file is, by definition, not a valid email message.

def sendMail(usr, pwd, to, body):
    msg = MIMEText(body)
    msg['From'] = usr
    msg['To'] = to
    msg['Subject'] = "Data add request"
    try:
        server = smtplib.SMTP('smtp.gmail.com', 587)
        server.ehlo()
        server.starttls()
        server.ehlo()
        server.login(usr, pwd)
        server.send_message("error-report@do_not_reply.com", [to],  msg)
    except Exception, err:
        print 'Error sending email: ', err
    finally:
        server.quit()

I switched to send_message here because it takes care of the minor mundane detail of converting the email.Message object to a string object again before calling sendmail.

It's not clear if you expect the body to be a text part displaying the contents of the string body, or a JSON attachment containing body as JSON, or perhaps both.

If you only need one body part, making the message multipart is obviously unnecessary. If you want multiple parts, then each of them should be a separate MIMEText or some other MIME container type which you can msg.attach() to a top-level MIMEMultipart.

I think it's the message : you should put for message

text = loaded_r.as_string()

And then you can send the mail .

server.sendmail("error-report@do_not_reply.com", to,  text)
