Python SMTP库空白电子邮件随着时间的推移

Posted 2021-04-15

我正在使用内置的Python库来发送电子邮件。一切正常，除非我把时间放在我发送的信息中。像7:30 pm。

当我在电子邮件中留出时间时，电子邮件收件人只会收到一封空白电子邮件。如果我删除时间，电子邮件发送就好了。我猜是时候搞砸了电子邮件。我应该在代码中更改什么，以便在电子邮件正文中留出时间。谢谢！

from smtplib import SMTP
def sendEmail(message,address):
    debuglevel = 0

    smtp = SMTP()
    smtp.set_debuglevel(debuglevel)
    #connect to the email server
    smtp.connect('smtp.gmail.com', 587)
    smtp.starttls()
    smtp.login('[e-mail]', 'ourpassword')
    #set the email to be sent from
    from_addr = "Auto Notification <sender email>"
    #send the email from our address and the message and recepients provided in the function definition.
    smtp.sendmail(from_addr, address, message)
    smtp.quit()

finalStr = "The  Girls Varsity Basketball  has been changed to 02/06/2018 at 7:30 pm * - ( previously 6:15 pm  ) at Clear Lake High School"

sendEmail(finalStr, '[e-mail]')

答案

在传输到SMTP服务器期间，某些字符被误解为控制字符。尝试将字符串编码为MIMEText：

from email.mime.text import MIMEText

#send the email from our address and the message and recepients provided in the function definition.
encoded_message = MIMEText(message).as_string()
smtp.sendmail(from_addr, address, encoded_message)

以下是传输时结果的不同之处。请注意，编码是在工作示例中声明的。

之前

send: b'The  Girls Varsity Basketball  has been changed to 02/06/2018 at 7:30 pm * - ( previously 6:15 pm  ) at Clear Lake High School
.
'

后：

send: b'Content-Type: text/plain; charset="us-ascii"
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit

The  Girls Varsity Basketball  has been changed to 02/06/2018 at 7:30 pm * - ( previously 6:15 pm  ) at Clear Lake High School
