AttributeError：'bytes'对象在python 3中没有属性'encode'

Question

email = 'aashita9317@gmail.com'
send_email('Happy Hour Update',message,
            from_addr=GMAIL_LOGIN, to_addr=email)

我收到一个错误 AttributeError: 'bytes' object has no attribute 'encode'

def send_email(subject, message, from_addr=GMAIL_LOGIN, to_addr=GMAIL_LOGIN):
msg = MIMEText(message)
msg['Subject'] = subject
msg['From'] = from_addr
msg['To'] = to_addr
msg['Reply-To'] = 'happyhours@noreply.com'

上面是它所引用的 send_email 函数，指向 msg = MIMEText(message) 请帮忙

if _charset is None:
        try:
            _text.encode('us-ascii')
            _charset = 'us-ascii'
        except UnicodeEncodeError:
            _charset = 'utf-8'

上面是它在 init(self, _text, _subtype, _charset, policy) 中的 ~\anaconda3\lib\email\mime\text.py 中引用的 anaconda3 文件

文档解释了字符集编码细节：https://docs.python.org/3/library/email.mime.html#email.mime.text.MIMEText

添加标题时，请使用例如msg.add_header('Subject', subject) 而不是msg['Subject'] = subject
