Python 电子邮件，[Errno 10061] 无法建立连接，因为目标机器主动拒绝它

Question

我想用python发送邮件，下面是我的代码，但最后我收到错误10061，希望有人能帮助我，谢谢！

import smtplib
fromaddr = 'XXX@XX.com'
toaddrs  = 'XXX@XX.com    '
msg = 'Why,Oh why!'
username = 'XXXXXX'
password = 'XXXXXX'
server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo()
server.starttls()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()

error msg:socket.error: [Errno 10061] 由于目标机器主动拒绝，无法建立连接

Answer 1

正如 Cid-EL 所说，You have to enable less secure apps in GMAIL settings

但是，打开该特定选项并不安全。

Gmail 提供 API 来执行邮件操作。 GMAIL API 支持多种语言。

对于 Python API：Python with Gmail

对于 Java API：Java with Gmail

稍加努力，但您可以获得安全的连接！

第 1 步：开启 GMAIL API

第 2 步：安装 Google 客户端库

pip install --upgrade google-api-python-client

第 3 步：使用 GMAIL API 发送邮件的代码示例

from __future__ import print_function
import httplib2
import os

from apiclient import discovery
import oauth2client
from oauth2client import client
from oauth2client import tools

try:
   import argparse
   flags = argparse.ArgumentParser(parents=[tools.argparser]).parse_args()

# at ~/.credentials/gmail-python-quickstart.json

def get_credentials():
  """Gets valid user credentials from storage.

  If nothing has been stored, or if the stored credentials are invalid,
  the OAuth2 flow is completed to obtain the new credentials.

  Returns:

  """
   home_dir = os.path.expanduser('~')
   credential_dir = os.path.join(home_dir, '.credentials')
   if not os.path.exists(credential_dir):

   credential_path = os.path.join(credential_dir,
                                'gmail-python-quickstart.json')

   store = oauth2client.file.Storage(credential_path)
   credentials = store.get()
   if not credentials or credentials.invalid:
      flow = client.flow_from_clientsecrets(CLIENT_SECRET_FILE, SCOPES)
      flow.user_agent = APPLICATION_NAME
      if flags:

据我所知，Gmail 和其他公司有安全措施来防止来自未知来源的电子邮件，但this link 可以关闭这种安全措施。

您可以在此处修改帐户，使其接受电子邮件。

我使用此代码发送电子邮件：

import smtplib

from email.mime.multipart import MIMEMultipart

from email.mime.text import MIMEText

from_address = 'johndoe@gmail.com'

to_address = 'johndoe@gmail.com'

message = MIMEMultipart('Foobar')

epos_liggaam['Subject'] = 'Foobar'

message['From'] = from_address

message['To'] = to_address

content = MIMEText('Some message content', 'plain')

message.attach(content)

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

mail.ehlo()

mail.starttls()

mail.login(from_address, 'password')

mail.sendmail(from_address,to_address, message.as_string())

mail.close()
