如何在python 3-x中仅通过smtplib发送电子邮件

问题描述

我想通过 smtplib 发送电子邮件，但它给了我错误

    server.send_message(user_name,to,message,subject=subject)
TypeError: send_message() got an unexpected keyword argument 'subject'

此代码

    import smtplib
    user_name = 'my@gmail.com'
    password = '*******'
    to = ['my@gmail.com','other_email@gmail.com']
    subject = 'Theme'
    message = 'Test message'
    server = smtplib.SMTP_SSL('smtp.gmail.com',465)
    server.ehlo()
    server.login(user_name,password)
    server.send_message(user_name,subject=subject)
    server.close()

我尝试从代码中删除主题，但它给了我新的错误

      File "C:\\lib\smtplib.py",line 939,in send_message
        resent = msg.get_all('Resent-Date')
    AttributeError: 'str' object has no attribute 'get_all'

我该如何解决这个问题？

编辑：

我找到了方法

import smtplib

gmail_user = 'my_gmail@gmail.com' #like boris273@gmail.com
gmail_password = 'password'

sent_from = gmail_user
to = ['email@gmail.com','email@gmail.com'] #Some emails to which your message will be sent
subject = input('Subject > ')
body = input('Message > ')
email_text = """\
From: %s
To: %s
Subject: %s

%s
""" % (sent_from,",".join(to),subject,body)

try:
    server = smtplib.SMTP_SSL('smtp.gmail.com',465)
    server.ehlo()
    server.login(gmail_user,gmail_password)
    server.sendmail(sent_from,email_text)
    server.close()
    print('Email sent!')
except:
    print('Something went wrong...')

现在使用 sendmail 而不是 send_message 编码

解决方法

您需要使用 sendmail() 而不是 send_message()

import smtplib
user_name = 'my@gmail.com'
password = '*******'
to = ['my@gmail.com','other_email@gmail.com']
subject = 'Theme'
message = 'Test message'
email_message = 'Subject: {}\n\n{}'.format(subject,message) 
server = smtplib.SMTP_SSL('smtp.gmail.com',465)
server.ehlo()
server.login(user_name,password)
server.send_message(user_name,to,email_message)
server.close()
