PYthon获取当天邮件附件下载

要使用Python获取当天邮件附件并下载，你需要安装Python的邮件处理库，例如`IMAPClient`和`email`库。下面是一个获取当天邮件附件并下载的示例代码：

import os
import sys
import datetime
from imapclient import IMAPClient
from email.header import decode_header
from email.utils import parsedate_to_datetime
from email.parser import BytesParser

# 邮箱连接配置
IMAP_SERVER = 'imap.example.com'
IMAP_PORT = 993
USERNAME = 'example@example.com'
PASSWORD = 'example_password'

# 附件下载路径
ATTACHMENT_PATH = './attachments/'

# 获取当天日期
today = datetime.datetime.today().strftime('%d-%b-%Y')

# 连接邮箱
with IMAPClient(IMAP_SERVER, use_uid=True) as client:
    client.login(USERNAME, PASSWORD)
    client.select_folder('INBOX')

    # 搜索当天日期的邮件
    messages = client.search(['SINCE', today])

    # 遍历每封邮件
    for message_id, data in client.fetch(messages, ['RFC822']).items():

        # 解析邮件
        message = BytesParser().parsebytes(data[b'RFC822'])
        subject = decode_header(message['Subject'])[0][0].decode()
        date = parsedate_to_datetime(message['Date'])
        for part in message.walk():

            # 判断是否为附件
            if part.get_content_disposition() == 'attachment':

                # 下载附件
                filename = part.get_filename()
                filepath = os.path.join(ATTACHMENT_PATH, filename)
                with open(filepath, 'wb') as f:
                    f.write(part.get_payload(decode=True))
                print(f'Downloaded attachment {filename} from {subject} ({date})')

这个示例代码连接到IMAP邮件服务器，搜索当天日期的邮件，并遍历每封邮件，如果有附件则下载到本地指定路径。你需要将示例代码中的IMAP_SERVER、IMAP_PORT、USERNAME、PASSWORD和ATTACHMENT_PATH替换为你的实际配置。
