利用python 脚本实现腾讯企业邮箱附件的批量下载

作者:互联网

因为有需求,所以自己就稍微琢磨了一下这个东西,然后代码是从网上找的,目前我已经自测过是可以使用的,而且非常方便省事,这里分享给大家!

直接上代码:

# _*_ coding: utf-8 _*_ import poplibimport emailimport osfrom email.parser import Parserfrom email.header import decode_headerfrom email.utils import parseaddr def decode_str(s):    value, charset = decode_header(s)[0]    if charset:        if charset == 'gb2312':            charset = 'gb18030'        value = value.decode(charset)    return value def get_email_headers(msg):    headers = {}    for header in ['From', 'To', 'Cc', 'Subject', 'Date']:        value = msg.get(header, '')        if value:            if header == 'Date':                headers['Date'] = value            if header == 'Subject':                subject = decode_str(value)                headers['Subject'] = subject            if header == 'From':                hdr, addr = parseaddr(value)                name = decode_str(hdr)                from_addr = u'%s <%s>' % (name, addr)                headers['From'] = from_addr            if header == 'To':                all_cc = value.split(',')                to = []                for x in all_cc:                    hdr, addr = parseaddr(x)                    name = decode_str(hdr)                    to_addr = u'%s <%s>' % (name, addr)                    to.append(to_addr)                headers['To'] = ','.join(to)            if header == 'Cc':                all_cc = value.split(',')                cc = []                for x in all_cc:                    hdr, addr = parseaddr(x)                    name = decode_str(hdr)                    cc_addr = u'%s <%s>' % (name, addr)                    cc.append(to_addr)                headers['Cc'] = ','.join(cc)    return headers def get_email_content(message, savepath):    attachments = []    for part in message.walk():        filename = part.get_filename()        if filename:            filename = decode_str(filename)            data = part.get_payload(decode=True)            abs_filename = os.path.join(savepath, filename)            attach = open(abs_filename, 'wb')            attachments.append(filename)            attach.write(data)            attach.close()    return attachments if __name__ == '__main__':    # 账户信息    email = 'sunn@nfu.edu.cn'    password = 'SUNxxx'    pop3_server = 'imap.exmail.qq.com'    # 连接到POP3服务器,带SSL的:    server = poplib.POP3_SSL(pop3_server)    # 可以打开或关闭调试信息:    server.set_debuglevel(0)    # POP3服务器的欢迎文字:    print(server.getwelcome())    # 身份认证:    server.user(email)    server.pass_(password)    # stat()返回邮件数量和占用空间:    msg_count, msg_size = server.stat()    print('message count:', msg_count)    print('message size:', msg_size, 'bytes')    # b'+OK 237 174238271' list()响应的状态/邮件数量/邮件占用的空间大小    resp, mails, octets = server.list()     for i in range(1, msg_count):        resp, byte_lines, octets = server.retr(i)        # 转码        str_lines = []        for x in byte_lines:            str_lines.append(x.decode())        # 拼接邮件内容        msg_content = '\n'.join(str_lines)        # 把邮件内容解析为Message对象        msg = Parser().parsestr(msg_content)        headers = get_email_headers(msg)        attachments = get_email_content(msg, r'/Users/sun/Desktop')         print('subject:', headers['Subject'])        print('from:', headers['From'])        print('to:', headers['To'])        if 'cc' in headers:            print('cc:', headers['Cc'])        print('date:', headers['Date'])        print('attachments: ', attachments)        print('-----------------------------')     server.quit()

这里主要说明2点:

比如,我使用的是腾讯企业邮箱,那么我的pop3_server就是:

a、收件服务器:imap.exmail.qq.com,使用SSL,端口号993b、发件服务器:smtp.exmail.qq.com,使用SSL,端口号465

经过本人测试,可正常运行程序!

以上如何附件中的文件命名后缀名都是规范的话,不是出现解码出错的问题,但是我下载的附件中我发现有一个.JPG,是大写字母的话好像就无法正确解码。

发生异常: UnicodeDecodeError'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

总结,文件规范命名基本上不会出现这样的下载错误。

最后附上代码的源作者:感谢作者,如有侵权,立刻删!

大家觉得还不错的话给个小❤️❤️~~~
