使用 python 发送电子邮件时如何解决身份验证错误

Question

我正在尝试使用 python 使用 gmail 帐户发送电子邮件，但我正在验证 error.I 已验证电子邮件地址和密码，但没有 problem.I甚至在 gmail 中启用不太安全的应用程序

from email.message import EmailMessage
import os
import smtplib

context = ssl.create_default_context()
with smtplib.SMTP_SSL('smtp.gmail.com',465, context = context) as 
smtp:
    smtp.login('monitorweight100@gmail.com','monitor weight')
    msg = EmailMessage()
    msg['Subject'] = 'confirm weight'
    msg['From'] = 'monitorweight100@gmail.com'
    msg['To'] = 'helloworld@gmail.com'
    msg.set_content('Detected recent activity')
    msg.add_alternative("""\

Answer 1

您正在使用 monitorweight@gmail.com 登录并尝试将 From 设置为另一个，monitorweight100@gmail.com.
保持不变 & 问题应该得到解决。
顺便说一句 msg 足以满足 smtp.sendmali().
试试这个..

msg['From'] = 'monitorweight@gmail.com'
# other codes...

smtp.semdmail(msg)
