在 Windows 上通过 django 发送电子邮件

Question

呃，到目前为止，我已经尝试了很多方法，我已经能够在网上找到，但无济于事。我的主要目标是从私有 LAN 上的基于 django 的 Web 应用程序发送电子邮件。我不在乎它是如何发生的...smtp 或 win32com 和前景...任何东西，只要它有效。

在 django shell 中使用 django 默认设置和此代码：

from django.core.mail import send_mail
send_mail('subject','message','myemail@email.com',['myemail@email.com'])

我收到此错误：

Traceback (most recent call last):
    File "<console>", line 1, in <module>
    File "C:\Python27_32\lib\site-packages\django\core\mail\__init__.py", line 50, in send_mail
        connection=connection).send()
    File "C:\Python27_32\lib\site-packages\django\core\mail\message.py", line 274, in send
        return self.get_connection(fail_silently).send_messages([self])
    File "C:\Python27_32\lib\site-packages\django\core\mail\backends\smtp.py", line 87, in send_messages
        new_conn_created = self.open()
    File "C:\Python27_32\lib\site-packages\django\core\mail\backends\smtp.py", line 48, in open
        local_hostname=DNS_NAME.get_fqdn())
    File "C:\Python27_32\lib\smtplib.py", line 250, in __init__
        (code, msg) = self.connect(host, port)
    File "C:\Python27_32\lib\smtplib.py", line 311, in connect
        (code, msg) = self.getreply()
    File "C:\Python27_32\lib\smtplib.py", line 359, in getreply
        + str(e))
SMTPServerDisconected: Connection unexpectedly closed: [Errno 10057] A request to send or 
receive data was disallowed because the socket is not connected and (when sending on a 
datagram socket using a sendto call) no address was supplied

深入研究代码后，我在 smtplib 中插入了一条打印语句，显示地址为('localhost', 25)。所以我不知道为什么它说没有提供地址。那时我发现了django-smtp-ssl.py 并在安装后将以下内容添加到我的设置中：

EMAIL_USE_TLS = True #also tried 1
EMAIL_BACKEND = 'django_smtp_ssl.SSLEmailBackend'
EMAIL_HOST = 'localhost'
EMAIL_HOST_USER = 'myemail@email.com'
EMAIL_HOST_PASSWORD = 'mypassword'
EMAIL_PORT = 465

然后执行相同的代码，我现在得到：

Traceback (most recent call last):
    File "<console>", line 1, in <module>
    File "C:\Python27_32\lib\site-packages\django\core\mail\__init__.py", line 50, in send_mail
        connection=connection).send()
    File "C:\Python27_32\lib\site-packages\django\core\mail\message.py", line 274, in send
        return self.get_connection(fail_silently).send_messages([self])
    File "C:\Python27_32\lib\site-packages\django\core\mail\backends\smtp.py", line 87, in send_messages
        new_conn_created = self.open()
    File "C:\Python27_32\lib\site-packages\django_smtp_ssl.py", line 12, in open
        local_hostname=DNS_NAME.getfqdn())
    File "C:\Python27_32\lib\smtplib.py", line 777, in __init__
        SMTP.__init__(self, host, port, local_hostname, timeout)
    File "C:\Python27_32\lib\smtplib.py", line 250, in __init__
        (code, msg) = self.connect(host, port)
    File "C:\Python27_32\lib\smtplib.py", line 311, in connect
        (code, msg) = self.getreply()
    File "C:\Python27_32\lib\smtplib.py", line 355, in getreply
        line = self.file.readline()
    File "C:\Python27_32\lib\smtplib.py", line 186, in readline
        chr = self.sslobj.read(1)
    File "C:\Python27_32\lib\ssl.py", line 160, in read
        return self._sslobj.read(len)
AttributeError: 'NoneType' object has no attribute 'read'

我还尝试在使用 Apache 的生产环境中通过 Outlook 和 win32com 发送邮件。我收到了几个不同的例外尝试，例如：'Server execution failed 和 'Call was rejected by callee'。虽然它可以在 django shell 中工作（当然）。

有没有人看到这些错误并找到解决方法？感谢您的帮助！

这是一种变通方法，简直就是伪劣，但它会完成工作，直到出现更好的解决方案。

首先，我创建了一个custom command，可以从manage.py 调用它，因为它不是从 Apache 服务器执行的（这进一步告诉我系统没有将 Apache 识别为自动生成电子邮件的有效用户，当然有一种告诉系统“没关系”的方法）。

之后，我在 Windows 任务计划程序中创建了一个每 30 分钟运行一次的任务（这足以实现目标）。行动：

Start a program  C:\python27_32\python.exe C:\www\myproject\manage.py send_email

myapp/management/commands/send_email.py

from django.core.management.base import BaseCommand
from myapp.util.gen_email import AutoEmail #custom code to generate email via win32com
from myapp.models import MyModel

class Command(BaseCommand):
    def __init__(self, *args, **kwargs):
        super(Command, self).__init__(*args, **kwargs)
        items = MyModel.objects.filter(status__in=['status_a','status_b'])
        if items:
            self.send_proc_email()

    def send_proc_email(self):
        subject = 'There are new items to process'
        to = 'someemail@email.com'
        message = ''
        email = AutoEmail(subject, message, to)

    def handle(self, *args, **kwargs):
        pass

远非最佳，我知道，但嘿，如果它有效......
