对于_socket.getaddrinfo（主机，端口，家庭，类型，原型，标志）中的资源：socket.gaierror：[Errno 11001] getaddrinfo失败

Question

我是 python 的新手。 我正在尝试使用 python 发送 email。 我已经启用了不太安全的应用程序访问并创建了应用程序密码，但收到此错误：

Traceback (most recent call last):
  File "C:\My mask detection\xe1.py", line 11, in <module>
    with smtplib.SMTP('smtplib.gmail.com',587)as smtp:
  File "C:\Users\Adarsh C\AppData\Local\Programs\Thonny\lib\smtplib.py", line 251, in __init__
    (code, msg) = self.connect(host, port)
  File "C:\Users\Adarsh C\AppData\Local\Programs\Thonny\lib\smtplib.py", line 336, in connect
    self.sock = self._get_socket(host, port, self.timeout)
  File "C:\Users\Adarsh C\AppData\Local\Programs\Thonny\lib\smtplib.py", line 307, in _get_socket
    self.source_address)
  File "C:\Users\Adarsh C\AppData\Local\Programs\Thonny\lib\socket.py", line 707, in create_connection
    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
  File "C:\Users\Adarsh C\AppData\Local\Programs\Thonny\lib\socket.py", line 752, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 11001] getaddrinfo failed 

我不明白这个错误指的是什么。 我想知道我在哪里做错了，或者在我开始编写代码之前我想做些什么。

我的代码：

import smtplib
import os

with smtplib.SMTP('smtplib.gmail.com',587)as smtp:
    smtp.ehlo()
    smtp.starttls()
    smtp.ehlo()

    smtp.login('helpdeskadhi@gmail.com','pnfnvboatmczopkn')
    subject = "hello"
    body = "Nice to meet you!"

    msg = f'Subject: {subject}\n\n{body}'

    smtp.sendmail('helpdeskadhi@gmail.com','helpdeskadhi@gmail.com',msg)

Answer 1

smtplib.SMTP('smtp.gmail.com',587)
