Django:邮件功能实现

django-users2和django的邮件功能模块都有相关的实现

-----------------------------------------------------------------------------------------

在所创建的项目下的settings下设置：

# Application definition

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'users',
    'bootstrap3',
]

#--------------------------------------
#django-users2
AUTH_USER_MODEL = 'users.User'
USERS_VERIFY_EMAIL = True  #开启用户注册邮件验证
USERS_SPAM_PROTECTION = False  #防止自动化注册的 True为开启 这个是我取消了防自动化验证功能，和email无关
#---------------------------

#Email-Settings
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_USE_TLS = False
EMAIL_HOST = 'smtp.126.com'
EMAIL_PORT = 25
EMAIL_HOST_USER = 'xautxuqiang'
EMAIL_HOST_PASSWORD = '*******'
DEFAULT_FROM_EMAIL = 'xautxuqiang@126.com'

注意哦：上面的EAMIL_HOST是126邮箱的smtp服务器，端口默认25.

EMAIL_HOST_USER和EMAIL_HOST_PASSWORD是邮件客户端的的账号和密码哦

这个需要下载相应的客户端注册账号哦。

DEFAULT_FROM_EMAIL就是向用户发送邮件的邮箱

完成以上配置就可以实现了....

django-users2中注册时发送邮件相关的代码

if request.method == 'POST':
        form = registration_form(request.POST)
        if form.is_valid():
            user = form.save()
            if settings.USERS_AUTO_LOGIN_AFTER_REGISTRATION:
                user.backend = 'django.contrib.auth.backends.ModelBackend'
                login(request, user)
            elif not user.is_active and settings.USERS_VERIFY_EMAIL:
                opts = {
                    'user': user,
                    'request': request,
                    'from_email': activation_from_email,
                    'email_template': activation_email_template_name,
                    'subject_template': activation_email_subject_template_name,
                    'html_email_template': activation_email_html_template_name,
                }
                send_activation_email(**opts)
                user_registered.send(sender=user.__class__, request=request, user=user)
            return redirect(post_registration_redirect)
    else:
        form = registration_form()

当 用户没被激活 且 配置settings 中的 USERS_VERIFY_EMAIL为True 时，向用户发送邮件

send_activation_send(**opts)函数 实现发送邮件

def send_activation_email(
        user=None, request=None, from_email=None,
        subject_template='users/activation_email_subject.html',
        email_template='users/activation_email.html', html_email_template=None):

    if not user.is_active and settings.USERS_VERIFY_EMAIL:
        token_generator = EmailActivationTokenGenerator()

        current_site = get_current_site(request)

        context = {
            'email': user.email,
            'site': current_site,
            'expiration_days': settings.USERS_EMAIL_CONFIRMATION_TIMEOUT_DAYS,
            'user': user,
            'uid': urlsafe_base64_encode(force_bytes(user.pk)),
            'token': token_generator.make_token(user=user),
            'protocol': 'https' if request.is_secure() else 'http',
        }

        subject = render_to_string(subject_template, context)
        # email subject *must not* contain newlines
        subject = ''.join(subject.splitlines())
        body = render_to_string(email_template, context)

        email_message = EmailMultiAlternatives(subject, body, from_email, [user.email])
        if html_email_template is not None:
            html_email = render_to_string(html_email_template, context)
            email_message.attach_alternative(html_email, 'text/html')

        email_message.send()

user_registered.send()使用来产生一个用户注册的信号

# A new user has registered.
user_registered = Signal(providing_args=['user', 'request'])
