使用 smptlib 发送的电子邮件缺少主题行

Question

我正在尝试使用 python 的 smptlib 发送电子邮件，它似乎工作正常，但没有附加主题密钥。（图片 [1]：https://i.stack.imgur.com/XkpLh.png）

我看过其他解决方案，但 none 对我有用。他们主要以 headers 的形式解决基于文本的添加，但我的代码涉及将数据帧作为 table 发送，当我尝试这些解决方案时它会搞砸。

我看过的帖子：

Python: "subject" not shown when sending email using smtplib module

Subject line not coming in the smtp mail sent from python

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

sender = 'email@email.com'
recipients = 'email@email.com'
subject = "Test Email 1234"


# Create message container - the correct MIME type is multipart/alternative.
msg = MIMEMultipart()

msg['From'] = sender
msg['To'] = ", ".join(recipients)
msg['Subject'] = subject

# Create the body of the message (a plain-text and an HTML version).

text = """

text

{table}


text

"""

html = """
<html>
<head>
<style> 
 table, th, td {{ border: 1px solid black; border-collapse: collapse; text-align: center;}}
 th, td {{ padding: 8px; }}


</style>
</head>

<body><p>text </p>
<br><br><br>
{table}
<br><br><br>
<p>Regards,</p>
<p>abc</p>
</body></html>
"""


col_list = list(df.columns.values)
data = df
# above line took every col inside csv as list
text = text.format(table=tabulate(data, headers=col_list, tablefmt="grid"))
html = html.format(table=tabulate(data, headers=col_list, tablefmt="html"))




msg = MIMEMultipart("alternative", None, [MIMEText(text), MIMEText(html,'html')])



# Send the message via local SMTP server.
server = smtplib.SMTP('smtp.gmail.com', 587)
server.ehlo()
server.starttls()
server.login("email@gmail.com", "pw")
server.sendmail(sender,recipients, msg.as_string())
server.quit()

Answer 1

您的设置

msg['From'] = sender
msg['To'] = ", ".join(recipients)
msg['Subject'] = subject

将被覆盖，只要你这样做

msg = MIMEMultipart("alternative", None, [MIMEText(text), MIMEText(html,'html')])

稍后。

只需调换他们的顺序并删除第一个 msg = MIMEMultipart()。
