使用Python下載發送到Gmail的MMS電子郵件

Question

所以我嘗試了下面的代碼，然后下載了附件。 問題出在我的gmail帳戶上，有一些通過彩信通過手機發送的電子郵件。 可以通過以下腳本下載來自移動網絡A的電子郵件附件，而來自移動網絡B的電子郵件附件將失敗。

以下是完整電子郵件詳細信息的鏈接： http : //pastie.org/private/ektv7yfa2xwdqzu77ys5a （來自移動網絡A，有效） http://pastie.org/private/cljaaad4tz7v5jra20l0q （來自移動網絡B，失敗）

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[0].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[0][1] # 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()

Answer 1

失敗的電子郵件的附件標題中未設置Content-Disposition，因此您可以跳過它。 看起來您將不得不放松一些檢查Content-Disposition的if語句。

也許您也可以看看Content-Type是否為image / jpeg並使用它。
