如何在smptlib中向电子邮件添加文件附件?

smtplib email python

mmewtwosaysbye · 技术社区 · 10 月前

我已经制作了一个电子邮件发送脚本,但我不知道如何使用它发送文件。帮助!

filename = 'image.png'
my_user = '[email protected]'  # 
my_pass = 'my app code' 

smtpserver = smtplib.SMTP_SSL('smtp.gmail.com', 465)
smtpserver.ehlo()
smtpserver.login(my_user, my_pass)

sent_from = my_user
sent_to = 'myotheremail'  #  Send it to self (as test)
email_text = 'This is a test'
smtpserver.sendmail(sent_from, sent_to, email_text, filename)

smtpserver.close()

要使用Python发送带有附件的电子邮件,您需要 除了smtplib之外,还可以使用电子邮件模块。 这个 smtplib.sendmail()方法 不直接处理附件,因此您需要构建包含附件的电子邮件。

我为您提供了下面的完整代码供您参考,您可以根据自己的意愿进行编辑:

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders

# Email configuration
filename = 'image.png'
my_user = '[email protected]'
my_pass = 'my app code'
sent_to = '[email protected]'  # Use your actual recipient email

# Creating email message
msg = MIMEMultipart()
msg['From'] = my_user
msg['To'] = sent_to
msg['Subject'] = 'Subject: Test Email with Attachment'

# Email body text
body = 'This is a test email with an attachment.'
msg.attach(MIMEText(body, 'plain'))

# Attach the file
attachment = open(filename, 'rb')
part = MIMEBase('application', 'octet-stream')
part.set_payload(attachment.read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', f'attachment; filename= {filename}')
msg.attach(part)

# Send the email
try:
    smtpserver = smtplib.SMTP_SSL('smtp.gmail.com', 465)
    smtpserver.login(my_user, my_pass)
    smtpserver.send_message(msg)
    print("Email sent successfully!")
except Exception as e:
    print(f"Failed to send email: {e}")
finally:
    smtpserver.quit()
    attachment.close()
