python - “MIMEText”对象没有属性 'encode'

Question

您好，我正在尝试找出为什么会出现此错误。这让我有点困惑。我正在使用Python 3.6

logger = logging.getLogger(__name__)
message_text = 'this is a test body'
message = MIMEText(message_text)
message['to'] = 'me@example.com'
message['from'] = 'you@example.com'
message['subject'] = 'test subject'
logger.debug('++++++++++++++++++++++++++++++++++')
logger.debug(message)
logger.debug('++++++++++++++++++++++++++++++++++')
try:
  raw = base64.urlsafe_b64encode(message.encode('UTF-8')).decode('ascii')
except Exception as e:
  logger.debug('---------------')
  logger.debug(e)
  logger.debug('---------------')

这就是输出。

++++++++++++++++++++++++++++++++++
Content-Type: text/plain; charset="us-ascii". 
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit.  
to: me@example.com
from: you@example.com
subject: test subject

this is a test body

Answer 1

MIMEText 没有 .encode() 方法，看起来您需要 as_string() 方法。

message.as_string() 将返回以下字符串:

Content-Type: text/plain; charset="us-ascii"
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit
to: me@example.com
from: you@example.com
subject: test subject

this is a test body

尝试一下:

raw = base64.urlsafe_b64encode(message.as_string().encode('UTF-8')).decode('ascii')
