使用 smtplib 库发送电子邮件时出现超时错误

问题描述

这是我的代码：

import smtplib

connection = smtplib.SMTP("smtp.gmail.com")
connection.starttls()
connection.login(user="[e-mail]",password="mypassowrd")
connection.sendmail(from_addr="[e-mail]",to_addrs="[e-mail]",msg="Hello")
connection.close()

所以我收到此错误：

Traceback (most recent call last):
  File "E:\100days-Python_programs\Day32\Birthday Wisher (Day 32) start\main.py",line 3,in <module>
    connection = smtplib.SMTP("smtp.gmail.com")
  File "C:\Users\HP\AppData\Local\Programs\Python\python39\lib\smtplib.py",line 253,in __init__
    (code,msg) = self.connect(host,port)
  File "C:\Users\HP\AppData\Local\Programs\Python\python39\lib\smtplib.py",line 339,in connect
    self.sock = self._get_socket(host,port,self.timeout)
  File "C:\Users\HP\AppData\Local\Programs\Python\python39\lib\smtplib.py",line 310,in _get_socket
    return socket.create_connection((host,port),timeout,File "C:\Users\HP\AppData\Local\Programs\Python\python39\lib\socket.py",line 843,in create_connection
    raise err
  File "C:\Users\HP\AppData\Local\Programs\Python\python39\lib\socket.py",line 831,in create_connection
    sock.connect(sa)
TimeoutError: [WinError 10060] A connection attempt Failed because the connected party did not properly respond after a period of time,or established connection Failed because connected host has Failed to respond

Process finished with exit code 1

我开启了不太安全的应用访问：

我也关闭了所有安全步骤：

我也关闭了防火墙保护。

但没有任何效果。

所以请有人帮助我。

解决方法

您需要指定端口。在本例中，587 为 TSL。

不知何故它有效，但我没有深厚的知识来解释为什么。

我遇到了同样的问题，所以有一个解决方案：

connection = smtplib.SMTP("smtp.gmail.com",587)
