How to attach file in an e-mail using ruby?

[littlemaster]

I have the following code, it is sending text message. I want to attach a file. How to do that?

require 'net/smtp' # plain mail
smtpclient = Net::SMTP::new( '192.168.1.1' ) # create new object to send mail
the_email="From: [e-mail]\nTo:[e-mail].i n\nSubject:Birthday \n\n"+"This is for demo" #Frame a mail
smtpclient.start # start the mail process
smtpclient.sendmail(the_email, '[e-mail]','[e-mail] ') # send mail via ruby
smtpclient.finish # operation finished.
puts "Mail sent Successfully "

Here is an example.

It is sending mail properly with text message. It is not attach the file. In that program no syntax specified to attach mail.I have already tried this example. Any other simplest example ???

There is a section near the bottom for adding attachments.

filename = "/tmp/test.txt"
# Read a file and encode it into base64 format
filecontent = File.read(filename)
encodedcontent = [filecontent].pack("m")   # base64
 
marker = "AUNIQUEMARKER"
 
...
 
# Define the attachment section
part3 =<<EOF
Content-Type: multipart/mixed; name=\"#{filename}\"
Content-Transfer-Encoding:base64
Content-Disposition: attachment; filename="#{filename}"
 
#{encodedcontent}
--#{marker}--
EOF

You then need to add part3 to your email.

Could you able to understand my question?

In sendmail function, there is no option to attach file. U can configure the file attachment details properly. How will you embed this ?

The attachment is part of the email. In sendmail, you send the complete email which already has attachments added.
