Hi all,
I'm trying to extract zip file (containing an xml file) from an email
so I can process it. But I'm running up against some brick walls.
I've been googling and reading all afternoon, and can't seem to figure
it out.
Here is what I have so far.
p = POP3("mail.serv er.com")
print p.getwelcome()
# authentication, etc.
print p.user("USER")
print p.pass_("PASS")
print "This mailbox has %d messages, totaling %d bytes." % p.stat()
msg_list = p.list()
print msg_list
if not msg_list[0].startswith('+O K'):
# Handle error
exit(1)
for msg in msg_list[1]:
msg_num, _ = msg.split()
resp = p.retr(msg_num)
if resp[0].startswith('+O K'):
#print resp, '============== =========\n'
#extract message body and attachment.
parsed_msg = email.message_f rom_string('\n' .join(resp[1]))
payload= parsed_msg.get_ payload(decode= True)
print payload #doesn't seem to work
else:
pass# Deal with error retrieving message.
How do I:
a) retrieve the body of the email into a string so I can do some
processing? (I can get at the header attributes without any trouble)
b) retrieve the zip file attachment, and unzip into a string for xml
processing?
Thanks so much for your help!

Hi,
some weeks ago I wrote some code to extract attachments from emails.
It's not that long, so maybe it could be of help for you:
-------------------------------------------
#!/usr/bin/env python
import poplib
import email
import os
import sys
import string
#
# attsave.py
# Check emails at PROVIDER for attachments and save them to SAVEDIR.
#
PROVIDER = "pop.YourMailPr ovider.de"
USER = "YourUserNa me"
PASSWORD = "YourPasswo rd"
SAVEDIR = "/home/YourUserDirecto ry"
def saveAttachment( mstring):
filenames = []
attachedcontent s = []
msg = email.message_f rom_string(mstr ing)
for part in msg.walk():
fn = part.get_filena me()
if fn <None:
filenames.appen d(fn)
attachedcontent s.append(part.g et_payload())
for i in range(len(filen ames)):
fp = file(SAVEDIR + "/" + filenames[i], "wb")
fp.write(attach edcontents[i])
print 'Found and saved attachment "' + filenames[i] + '".'
fp.close()
try:
client = poplib.POP3(PRO VIDER)
except:
print "Error: Provider not found."
sys.exit(1)
client.user(USE R)
client.pass_(PA SSWORD)
anzahl_mails = len(client.list ()[1])
for i in range(anzahl_ma ils):
lines = client.retr(i + 1)[1]
mailstring = string.join(lin es, "\n")
saveAttachment( mailstring)
client.quit()
-------------------------------------------
See you
H.
Thanks H!
I'm now able to get the name of the zip file, and the contents (is it
still encoded?).
I now need to be able to unzip the zip file into a string and get the
body of the email into a string.
Here is my updated code:
p = POP3("mail.**** ******.com")
print p.getwelcome()
# authentication, etc.
print p.user("USER")
print p.pass_("PASS")
print "This mailbox has %d messages, totaling %d bytes." % p.stat()
msg_list = p.list()
print msg_list
if not msg_list[0].startswith('+O K'):
# Handle error in listings
exit(1)
for msg in msg_list[1]:
msg_num, _ = msg.split()
resp = p.retr(msg_num)
if resp[0].startswith('+O K'):
#print resp, '============== =========\n'
parsed_msg = email.message_f rom_string('\n' .join(resp[1]))
for part in parsed_msg.walk ():
fn = part.get_filena me()
if fn <None:
fileObj = StringIO.String IO()
fileObj.write( part.get_payloa d() )
#attachment = zlib.decompress (part.get_paylo ad())
#print zipfile.is_zipf ile(fileObj)
attachment = zipfile.ZipFile (fileObj)
print fn, '\n', attachment
payload= parsed_msg.get_ payload(decode= True)
print payload
else:
pass# Deal with error retrieving message.
I get this error:
Traceback (most recent call last):
File "wa.py", line 208, in <module>
attachment = zipfile.ZipFile (fileObj)
File "/usr/lib/python2.5/zipfile.py", line 346, in __init__
self._GetConten ts()
File "/usr/lib/python2.5/zipfile.py", line 366, in _GetContents
self._RealGetCo ntents()
File "/usr/lib/python2.5/zipfile.py", line 378, in _RealGetContent s
raise BadZipfile, "File is not a zip file"
zipfile.BadZipf ile: File is not a zip file
Is the zip file still encoded? Or am I passing in the wrong arguments
to the zipfile module?
Thanks for your help!
Erik
