如何批量下载BOSS直聘候选人发往邮箱的简历附件

虽然是用在接收BOSS直聘邮件的,但也可以改为其他邮箱,不过解析需要自己修改

import imaplib
import email
import os
import base64
from email.header import decode_header
import re
# 邮箱信息
email_user = ''
email_pass = ''

# 连接到IMAP服务器
imap_server = 'imap.xxx'  # 请替换成你的邮箱提供商的IMAP服务器地址
imap = imaplib.IMAP4_SSL(imap_server)

# 登录到邮箱
imap.login(email_user, email_pass)

# 选择邮箱文件夹（如收件箱）
folder = 'INBOX'  # 可以根据需要更改为其他文件夹
imap.select(folder)

# 设置搜索条件（日期和发件人）
search_criteria = '(FROM "cv@service.bosszhipin.com" SINCE "14-SEP-2023")'

# 搜索匹配的邮件
status, email_ids = imap.search(None, search_criteria)

# 遍历匹配的邮件
for email_id in email_ids[0].split():
    # 获取邮件
    status, email_data = imap.fetch(email_id, '(RFC822)')
    raw_email = email_data[0][1]

    # 解析邮件
    msg = email.message_from_bytes(raw_email)
    
    # 遍历附件
    for part in msg.walk():
        if part.get_content_maintype() == 'multipart':
            continue
        if part.get('Content-Disposition') is None:
            continue

        # 获取附件名称并解码
        filename = part.get_filename()
        if filename:
            filename, encoding = decode_header(filename)[0]
            if isinstance(filename, bytes):
                filename = filename.decode(encoding or 'utf-8')

            # 处理Base64编码的附件内容
            file_data = part.get_payload(decode=True)
            file_data_decoded = base64.b64decode(file_data)
            filename = filename[1:]           # 保存附件
            filename = "".join(x for x in filename if x.isalnum() or x in ["-", "_", "."])
            # 解码 Base64 编码的附件内容
              # 解码 Base64 编码的附件内容
            payload = part.get_payload(decode=True)
            try:
                payload_decoded = payload.decode('utf-8')
            except UnicodeDecodeError:
                payload_decoded = payload

            # 保存附件到 D 盘的 A 文件夹下
            file_path = os.path.join('D:\\A\\', filename)  # 替换为你想保存附件的文件夹路径
            with open(file_path, 'wb') as file:
                file.write(payload_decoded)

# 关闭连接
imap.logout()
