outlook邮件循环接收，附件分文件存放

因开发流程需要使用outlook收取邮件，发现通过控件有一定的劣势，研究了RPA的邮件发送源码后，自己写一个循环接收未读邮件的代码，并将每一封邮件中的附件分文件夹存放。

简单直接，上代码

from ubpa import ioutlook
from ubpa import iresult
from ubpa.ilog import ILog
import tempfile
import os


__logger = ILog(__file__)
__attachment_path = tempfile.gettempdir() + os.sep  # 默认保存路径


def recv_outlook(mail_account, subject_filter, mail_inbox, attachment_path, top, mark_as_read=True, only_unread=True):
    '''
    :param mail_account:    邮箱
    :param subject_filter: 主题
    :param mail_inbox:     收件箱名称
    :param attachment_path: 附件路径
    :param top:     一次读取几封邮件
    :param mark_as_read: 标为已读邮件
    :param only_unread: 查找未读邮件
    :return: tuple（邮件对象，未读邮件总数）
    '''
    # 邮件列表
    mails = []
    num = 1

    inbox = ioutlook.get_inbox(mail_account, mail_inbox)
    if inbox:
        messages = inbox.Items

        if only_unread:
            messages = messages.Restrict('[UnRead] = True')  # 未读取的邮件

        messages.Sort("[ReceivedTime]", True)  # 收件时间倒序

        # 未读邮件总数
        total_num = len(messages)
        if not top:
            top = len(messages)

        __logger.debug(u"total receive[" + str(len(messages)) + "]copies of mails,get Topn:" + str(top))

        # 循环未读邮件
        for message in messages:
            # 附件列表
            atts = []

            if num > top:
                break

            sender = message.SenderEmailAddress  # 发件人地址
            subject = message.Subject  # 主题
            body = message.Body  # 正文
            cc = message.CC  # 抄送
            received_time = str(message.ReceivedTime)  # 收件时间
            attachments = message.Attachments  # 附件

            # 判断主题是否存在
            if subject_filter and subject_filter not in subject:
                continue
            else:
                flag = True

            # 如上，这里可以加多个判断条件，如：sender_filter、body_filter 等的过滤

            # 循环附件
            for attachment in attachments:
                file_name = attachment.FileName
                att_file_path = attachment_path + os.sep + file_name
                attachment.SaveAsFile(att_file_path)
                atts.append(att_file_path)

            if flag:
                mail_message = iresult.MailMessage()    # 实例化

                # 属性赋值
                mail_message.sender_mail = sender
                mail_message.received_time = received_time
                mail_message.subject = subject
                mail_message.body = body
                mail_message.cc = cc
                mail_message.attachments = atts

                mails.append(mail_message)

                num += 1

                if mark_as_read:
                    message.UnRead = False  # 标志为已读
            print('附件:', atts)
        return mails, total_num


# 循环接收符合条件的未读邮件，直到收取完毕
n = 1
while True:
    fp = r"C:\Users\rongg\Desktop\新建文件夹\附件aaa%s" % n
    if not os.path.exists(fp):
        os.mkdir(fp)
    try:
        email, total_mail_num = recv_outlook('[email protected]', '测试', '收件箱', fp, 1)

        print('邮件对象：', email)
        print('邮件发件人：', email[0].sender_mail)
        print('邮件主题：', email[0].subject)
        print('邮件正文：', email[0].body)
        print('邮件总数：', total_mail_num)
        print('-' * 100)

    except IndexError:
        print('没有未读邮件')
    if total_mail_num <= 1:
        break
    n += 1
