脚本在python，下载邮件附件

Question

我有以下脚本：

import imaplib 
import email 
import os 

svdir = 'c:/downloads' 

mail = imaplib.IMAP4('https://outlook.office365.com/mapi/emsmdb/?' 
        'MailboxId=6ebd46ee-55df-452e-a0af-44e7b248d992@jmawireless.com') 
mail.login("RNa", "RN!") 
mail.select("ADP Files") 

typ, msgs = mail.search(None, '(SUBJECT "ADP Files")') 
msgs = msgs[0].split() 

for emailid in msgs: 
    resp, data = mail.fetch(emailid, "(RFC822)") 
    email_body = data[0][1] 
    m = email.message_from_string(email_body) 

    if m.get_content_maintype() != 'multipart': 
     continue 

    for part in m.walk(): 
     if part.get_content_maintype() == 'multipart': 
      continue 
     if part.get('Content-Disposition') is None: 
      continue 

     filename = part.get_filename() 
     if filename is not None: 
      sv_path = os.path.join(svdir, filename) 
      if not os.path.isfile(sv_path): 
       print(sv_path) 
       fp = open(sv_path, 'wb') 
       fp.write(part.get_payload(decode=True)) 
       fp.close() 

中产生的错误是：

C:\Users\rnandipati\Desktop\Batch Files\EMAIL ADP>email.py 

Traceback (most recent call last): 
    File "C:\Python34\lib\encodings\idna.py", line 165, in encode 
    raise UnicodeError("label empty or too long") UnicodeError: label empty or too long 

The above exception was the direct cause of the following exception: 
Traceback (most recent call last): 
    File "C:\Users\rnandipati\Desktop\Batch Files\EMAIL ADP\email.py", line 2, in <module> 
     import email 
    File "C:\Users\rnandipati\Desktop\Batch Files\EMAIL ADP\email.py", line 8, in <module> 
     mail=imaplib.IMAP4('https://outlook.office365.com/mapi/emsmdb/?MailboxId=6ebd46ee-55df-452e-a0af-44e7b248d992@jmawireless.com') 
    File "C:\Python34\lib\imaplib.py", line 181, in __init__ 
     self.open(host, port) 
    File "C:\Python34\lib\imaplib.py", line 257, in open 
     self.sock = self._create_socket() 
    File "C:\Python34\lib\imaplib.py", line 247, in _create_socket 
     return socket.create_connection((self.host, self.port)) 
    File "C:\Python34\lib\socket.py", line 494, in create_connection 
     for res in getaddrinfo(host, port, 0, SOCK_STREAM): 
    File "C:\Python34\lib\socket.py", line 533, in getaddrinfo 
     for res in _socket.getaddrinfo(host, port, family, type, proto, flags): UnicodeError: encoding with 'idna' codec failed (UnicodeError: label empty or to o long) 

我不知道为什么这个错误产生的。我对这种脚本很陌生。

根据文档（和源代码太），构造imaplib.IMAP4()两个参数：主机：主机名（通常是一个服务器名或IP地址），默认为“本地主机”，和端口 ：端口号，默认为标准IMAP4端口）。

在这里，您使用的URL是错误的。

尝试打开这样的连接：

with imaplib.IMAP4("outlook.office365.com") as imap4: 
    ... 

咨询此页拥有Office 360​​的连接设置：POP and IMAP settings for Outlook Office 365 for business

您可能需要为Outlook办公室SSL连接365这里是一个更有用的使用示例：

import imaplib 

username = 'user@example.com' 
password = 'password' 

with imaplib.IMAP4_SSL('outlook.office365.com') as imap4: 
    imap4.login(username, password) 

    # retrieve a list of the mailboxes and select one 
    result, mailboxes = imap4.list() 
    imap4.select("inbox") 

编辑：选择对象不with声明

try: 
    imap4.login(username, password) 

    # retrieve a list of the mailboxes and select one 
    result, mailboxes = imap4.list() 
    imap4.select("inbox") 

finally: 
    imap4.close()
