python下载.msg文件的附件

.msg文件，outlook邮件的一种保存方式

方式一：使用win32com库，不过要安装outlook才行

import win32com.client
import os

def get_attachments(file_dir, dst_dir):
    """
    获取.msg文件内的附件
    :param file_dir: .msg文件路径
    :param dst_dir: 附件存放目录
    :return: None
    """
    outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
    msg = outlook.OpenSharedItem(file_dir)
    '''
    print(msg.SenderName)
    print(msg.SenderEmailAddress)
    print(msg.SentOn)
    print(msg.To)
    print(msg.CC)
    print(msg.BCC)
    print(msg.Subject)
    print(msg.Body)
    '''
    count_attachments = msg.Attachments.Count
    attachments = msg.Attachments
    if count_attachments > 0:
        # for item in range(count_attachments):
        #     print(msg.Attachments.Item(item + 1).Filename)  # 循环输出附件名
        for att in attachments:
            att.SaveAsFile(os.path.join(dst_dir, att.FileName))

    del outlook, msg  # 释放资源

方式二：使用extract_msg库

import extract_msg

file_name = r"E:\test\test_email.msg"
msg = extract_msg.Message(file_name)
"""
print(msg.subject)
print(msg.cc)
print(msg.bcc)
print(msg.sender)
print(msg.to)
print(msg.path)
print(msg.attachments)
print(msg.date)
print(msg.body)
print(msg.htmlBody)
"""
for attachment in msg.attachments:
    attachment.save(customPath='E:/test')
