python - 无法在Python中发送电子邮件。[Errno 61]发生连接拒绝错误

Question

无法在 Python 中发送电子邮件。我想使用 Gmail 发送电子邮件。我在views.py中编写了代码，例如

    def mail(mail_adress, docx):

            msg = MIMEMultipart()
            msg["Subject"] = "TEST"
            msg["From"] = settings.EMAIL_HOST_USER
            msg["To"] = email

            message = "TEST"
            body = MIMEText(message)
            msg.attach(body)

            mime = {'type': 'text', 'subtype': 'docx'}
            attach_file = {'name': 'test.docx', 'path': '/Users/test.docx'}

            attachment = MIMEBase(mime['type'], mime['subtype'])
            file = open(attach_file['path'], 'rb')
            attachment.set_payload(file.read())
            file.close()
            encoders.encode_base64(attachment)
            msg.attach(attachment)
            attachment.add_header("Content-Disposition", "attachment", filename=attach_file['name'])

            return msg

    def send(from_addr, to_addrs, msg):
        smtp = smtplib.SMTP()
        smtp.connect()

        from_addr = 'xxxx@gmail.com'
        from_addr_name = "test"
        to_addr= "yyyyy@gmail.com"
        subject = u"test"
        message = "test"
        body = MIMEText(message)
        mime = {'type': 'text', 'subtype': 'docx'}
        attach_file = {'name': 'test.docx', 'path': '/Users/test.docx'}

        msg = mail(from_addr, from_addr_name, to_addr, subject, body, mime, attach_file)
        smtp.sendmail(from_addr, to_addrs, msg)
        smtp.close()

    send()

在设置.py

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'xxxx@gmail.com'
EMAIL_HOST_PASSWORD = 'xxxxxxxxx'
EMAIL_USE_TLS = True

当我运行代码时，[Errno 61] 连接被拒绝错误发生。Traceback 说

Traceback (most recent call last):

    sock.connect(sa)
ConnectionRefusedError: [Errno 61] Connection refused

我真的不明白为什么会发生这样的错误。我的代码出了什么问题？我应该如何解决这个问题？

Answer 1

1. 设置.py

   EMAIL_HOST = 'smtp.gmail.com'
   EMAIL_PORT = 587
   EMAIL_HOST_USER = 'xxxx@gmail.com'
   EMAIL_HOST_PASSWORD = 'xxxxxxxxx'
   EMAIL_USE_TLS = True
   EMAIL_USE_SSL = False 
   

2. 转至您的 Google 帐户设置，找到安全 -> 帐户权限 -> 访问安全性较低的应用，启用允许安全性较低的应用登录选项。 https://support.google.com/accounts/answer/6010255

[Errorno 61] 是由于服务器拒绝连接造成的。看看这是否有帮助。
