How do I connect to Gmail and determine which messages have attachments? I then want to download each attachment, printing out the Subject: and From: for each message as I process it.
Hard one :-)
import email, getpass, imaplib, os detach_dir = '.' # directory where to save attachments (default: current) user = raw_input("Enter your GMail username:") pwd = getpass.getpass("Enter your password: ") # connecting to the gmail imap server m = imaplib.IMAP4_SSL("imap.gmail.com") m.login(user,pwd) m.select("[Gmail]/All Mail") # here you a can choose a mail box like INBOX instead # use m.list() to get all the mailboxes resp, items = m.search(None, "ALL") # you could filter using the IMAP rules here (check http://www.example-code.com/csharp/imap-search-critera.asp) items = items.split() # getting the mails id for emailid in items: resp, data = m.fetch(emailid, "(RFC822)") # fetching the mail, "`(RFC822)`" means "get the whole stuff", but you can ask for headers only, etc email_body = data # getting the mail content mail = email.message_from_string(email_body) # parsing the mail content to get a mail object #Check if any attachments at all if mail.get_content_maintype() != 'multipart': continue print "["+mail["From"]+"] :" + mail["Subject"] # we use walk to create a generator so we can iterate on the parts and forget about the recursive headach for part in mail.walk(): # multipart are just containers, so we skip them if part.get_content_maintype() == 'multipart': continue # is this part an attachment ? if part.get('Content-Disposition') is None: continue filename = part.get_filename() counter = 1 # if there is no filename, we create one with a counter to avoid duplicates if not filename: filename = 'part-%03d%s' % (counter, 'bin') counter += 1 att_path = os.path.join(detach_dir, filename) #Check if its already there if not os.path.isfile(att_path) : # finally write the stuff fp = open(att_path, 'wb') fp.write(part.get_payload(decode=True)) fp.close()
Wowww! That was something. ;-) But try the same in Java, just for fun!
By the way, I tested that in a shell, so some errors likely remain.
Because mail-box names can change from one country to another, I recommend doing
m.list() and picking an item in it before
m.select("the mailbox name") to avoid this error:
imaplib.error: command SEARCH illegal in state AUTH, only allowed in states SELECTED
I'm not an expert on Perl, but what I do know is that GMail supports IMAP and POP3, 2 protocols that are completely standard and allow you to do just that.
Maybe that helps you to get started.
