我有一个由两个不同的函数生成的文本文件和 html 文件的列表。每个文件都标有 signal1.txt、signal2 等和 signal1.html、signal2.html 等。我需要发送包含每个文件对的电子邮件（signal1.txt 和 signal1.html、signal2.txt 和 signal.2。 html 等）。我尝试了几种不同的方法，但我一直只附加一对文件（最后一个文件编号，不管它是什么）。我发送一种文件类型没有问题，但是当我尝试使用两种不同的文件时它会变得混乱。
任何帮助表示赞赏。代码如下
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email.mime.text import MIMEText
from email import encoders
import smtplib, ssl
import os
dirname = r'C:\Path\To\Files'
ext = ('.txt','html')
for files in os.scandir(dirname):
if files.path.endswith(ext):
def sendmail():
html_body = '''
<html>
<body>
<p style="font-size: 12;"> <strong>Alert</strong><br>{html}</p>
</body>
</html>
'''.format(html=html)
subject = f'Text file content'
senders_email = '[email protected]'
receiver_email = '[email protected]'
# Create a multipart message and set headers
message = MIMEMultipart('alternative')
message['From'] = senders_email
message['To'] = receiver_email
message['Subject'] = subject
#Attach email body
message.attach(MIMEText(html_body, 'html'))
# Name of the file to be attached
filename = f'signal.html'
# Open file in binary mode
with open(filename, 'rb') as attachment:
# Add file as application/octet-stream
part = MIMEBase('application', 'octet-stream')
part.set_payload(attachment.read())
# Encodes file in ASCII characters to send via email
encoders.encode_base64(part)
# Add header as key/value pair to attachment part
part.add_header(
'Content-Disposition',
f"attachment; filename= {filename}",
)
# Add attachment to message and convert message to string
message.attach(part)
text = message.as_string()
# Log into server using secure connection
context = ssl.create_default_context()
with smtplib.SMTP("smtp.mail.com", 25) as server:
# server.starttls(context=context)
# server.login(senders_email, 'password')
server.sendmail(senders_email, receiver_email, text)
print("Email sent!")
sendmail()
