Question

我看过视频并练习过同样的事情，但我一直收到 smtp 连接错误

EMAIL_BACKEND= 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'captainleon04@gmail.com'
EMAIL_HOST_PASSWORD ='ppbdhcdnj'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

Answer 1

这是一个示例代码，它显示了如何关闭与服务器的连接server.quit()。

import smtplib

server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
server.login("your username", "your password")
server.sendmail(
  "from@address.com", 
  "to@address.com", 
  "this message is from python")
server.quit()
