Python smtplib send_message()失败,返回AttributeError:'str'对象没有属性'get_all'

Question

我正在开发一个项目,我必须使用Python 3.4中的smtplib和email模块发送电子邮件.

我能够自己创建电子邮件,我可以连接到服务器,但它会返回此异常:

reply: b'235 2.7.0 Accepted\r\n'
reply: retcode (235); Msg: b'2.7.0 Accepted'
send: 'QUIT\r\n'
reply: b'221 2.0.0 closing connection s66sm8304113yhp.2 - gsmtp\r\n'
reply: retcode (221); Msg: b'2.0.0 closing connection s66sm8304113yhp.2 - gsmtp'
Traceback (most recent call last):
  File "base.py", line 108, in <module>
    send(fromaddr, toaddrs, msg)
  File "base.py", line 61, in send
    server.send_message(fromaddr, toaddrs, msg)
  File "/usr/lib/python3.4/smtplib.py", line 829, in send_message
    resent = msg.get_all('Resent-Date')
AttributeError: 'str' object has no attribute 'get_all'

代码(直接链接到麻烦的线)可用在这里.奇怪的是,代码实际上在实际发送任何电子邮件正文之前发送了QUIT - 不确定这是否会影响这一点.

有谁知道导致此错误的原因是什么？

编辑原来我的部分问题是我使用的格式不正确.send_message()需要变量的顺序Message, From, To,而我的代码是按顺序发送的From, To, Message.

但是,我现在收到此错误:

reply: b'235 2.7.0 Accepted\r\n'
reply: retcode (235); Msg: b'2.7.0 Accepted'
send: 'QUIT\r\n'
reply: b'221 2.0.0 closing connection s66sm8443316yhp.2 - gsmtp\r\n'
reply: retcode (221); Msg: b'2.0.0 closing connection s66sm8443316yhp.2 - gsmtp'

签名SMTP.send_message不一样SMTP.sendmail.所以尝试:

    server.send_message(msg, fromaddr, toaddrs)

编辑:

您还需要To:单独添加标题,而不是列表:

    for item in input("To: ").split():
        msg['To'] = item
