使用 Python 发送电子邮件时，msg["Subject"] 变量的行为不正常

Question

我用 Python 发送电子邮件，但是 msg["Subject"] 变量填充了电子邮件的正文而不是主题框，而变量 body 没有填充任何内容...

其他都没问题，就是想不通为什么主体是body，body是空的？我错过了什么？

代码如下：

from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

msg = MIMEMultipart()
msg['From'] = "myemail@gmail.com"
msg['To'] = 'anemail@hotmail.com'
msg['Subject'] = "for next delivery, please supply"

body = Merged_Dp_Ind_str
msg.attach(MIMEText(body, 'plain'))

text = msg.as_string()
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login('username@gmail.com', 'password1')
server.sendmail(msg['From'], msg['To'], msg['Subject'])
server.quit()

您的消息很好，但实际上您没有发送；您只发送主题。

server.sendmail(msg['From'], msg['To'], msg['Subject'])

你的意思显然是

server.sendmail(msg['From'], msg['To'], text)

但是，您可能应该更新代码以改用现代 Python 3.6+ API。

格式化和发送消息的正确现代方式类似于

import smtplib
from email.message import EmailMessage

msg = EmailMessage()
msg['From'] = "myemail@gmail.com"
msg['To'] = 'anemail@hotmail.com'
msg['Subject'] = "for next delivery, please supply"
msg.set_content(Merged_Dp_Ind_str)

with smtplib.SMTP('smtp.gmail.com', 587) as server:
    server.starttls()
    server.login('username@gmail.com', 'password1')
    server.send_message(msg)
    server.quit()

使用 Python 发送电子邮件时，msg["Subject"] 变量的行为不正常

Sending email with Python, the msg["Subject"] variable doesn't behave as it should

python
