如何使用 Python 3.6 发送电子邮件附件

你介意帮我一下吗？ 我使用此页面中的所有代码如何使用Python发送电子邮件附件 https://stackoverflow.com/questions/3362600/how-to-send-email-attachments-with-python

但没有成功=(

这是我使用的最后一个版本

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

filepath = 'D:/files/1.jpg'
fromaddr = "[email protected] /cdn-cgi/l/email-protection"
toaddr = "[email protected] /cdn-cgi/l/email-protection"
password = '********'
mail_adr = 'smtp.gmail.com'
mail_port = 587

# Compose attachment
part = MIMEBase('application', "octet-stream")
part.set_payload(open(filepath, "rb").read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', "attachment; filename= %s" % os.path.basename(filepath))

# Compose message
msg = MIMEMultipart()
msg['From'] = fromaddr
msg['To'] = toaddr
msg.attach(part)

# Send mail
smtp = SMTP_SSL()
smtp.set_debuglevel(1)
smtp.connect(mail_adr, mail_port)
smtp.login(fromaddr, password)
smtp.sendmail(fromaddr, toaddr, msg.as_string())
smtp.quit()

这是我犯的错误

connect: ('smtp.gmail.com', 587)
connect: ('smtp.gmail.com', 587)
Traceback (most recent call last):
  File "C:/Users/Oleg/Desktop/444.py", line 31, in <module>

你有没有尝试过emailpy https://pypi.org/project/emailpy/？ （我是作者）

它支持任何附件格式，除非您的电子邮件提供商限制它。

Example:

import emailpy
emailManager = emailpy.EmailManager('[email protected] /cdn-cgi/l/email-protection', 'youremailpassword') # this may take a few seconds to generate
emailManager.send(['[email protected] /cdn-cgi/l/email-protection', '[email protected] /cdn-cgi/l/email-protection'],  \
subject = 'Subject here', body = 'body text here', html = 'some html here', \
attachments = ['file1.png', 'file2.txt', 'file3.py'], \
nofileattach = {'file.txt': 'hi, this is some data'}) 
# send email to [email protected] /cdn-cgi/l/email-protection and [email protected] /cdn-cgi/l/email-protection with subject "Subject here"
#, body "body text here", html "some html here", and some attachments: 
# "file1.png", "file2.txt", "file3.py". Also, it adds a file called file.txt
# that has the contents "hi, this is some data"

emailpy 文档可以在其 PyPI 页面上下载，也可以从here https://api.onedrive.com/v1.0/shares/u!aHR0cHM6Ly8xZHJ2Lm1zL3UvcyFBbzNpSVRXZV9FWmdqSVVSWmJQdXpIRkliY2xCV3c_ZT1JNXNSamI/root/content

所有电子邮件服务器都已成功使用emailpy进行了测试，并且在python 3.x上使用emailpy不会出现任何错误（python 2中不支持emailpy，主要是因为语法）
