How to get subject, content, etc fetched via Net::IMAP

I'm facing trouble decoding messages fetched through ruby's Net::IMAP, here's what I've tried in console

imap = Net::IMAP.new(‘imap.gmail.com’,993,true)
imap.login(“[email protected]”, “mypassword”)
imap.select(‘INBOX’)

msgs = []

imap.uid_search(["NOT", "DELETED"]).each do |uid|
  msgs << imap.uid_fetch(uid, ['RFC822']).first.attr['RFC822'].to_s
end

Now when I'm doing msgs.first I'm getting this

"Return-Path: <[email protected]>\r\n
Received: from 192.168.10.191:3000 ([111.93.167.67])\r\n

How to decode this, please help. I'm new to this feature.

Try using something like this:

body1 = imap.fetch(uid, "RFC822")[0].attr["RFC822"]
mail = Mail.new(body1)
subject = mail.subject
to      = mail.to

like that you could take all the value.

When you retrieve RFC822 you get the whole thing. If you retrieve BODY.PEEK[HEADER.FIELDS (Subject)] you'll get just the subject. (There's also an ENVELOPE which can be quite handy, it contains Subject, From and a few more, neatly parsed for you.) Fetching the body (I assume that's what you mean by content) is a little more tricky, you need to first retrieve the bodystructure, then retrieve the parts you want, often BODY.PEEK[1] or BODY.PEEK[1.2] or somesuch.
