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('+OK'):
# 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('+OK'):
#print resp, '=======================\n'
parsed_msg = email.message_from_string('\n'.join(resp[1]))
for part in parsed_msg.walk():
fn = part.get_filename()
if fn <> None:
fileObj = StringIO.StringIO()
fileObj.write( part.get_payload() )
#attachment = zlib.decompress(part.get_payload())
#print zipfile.is_zipfile(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._GetContents()
File "/usr/lib/python2.5/zipfile.py", line 366, in _GetContents
self._RealGetContents()
File "/usr/lib/python2.5/zipfile.py", line 378, in _RealGetContents
raise BadZipfile, "File is not a zip file"
zipfile.BadZipfile: 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
