Question

我想在我的Django应用程序中记录用户IP地址，特别是登录，注销和失败的登录事件。我正在使用Django内置函数，如下所示：

from django.contrib.auth.signals import user_logged_in, user_logged_out, user_login_failed
from ipware.ip import get_ip
import logging

logger = logging.getLogger(__name__)

def log_logged_in(sender, user, request, **kwargs):
    logger.info("%s User %s successfully logged in" % (get_ip(request), user))

def log_logged_out(sender, user, request, **kwargs):
    logger.info("%s User %s successfully logged out" % (get_ip(request), user))

def log_login_failed(sender, credentials, **kwargs):
    logger.warning("%s Authentication failure for user %s" % ("...IP...", credentials['username']))

user_logged_in.connect(log_logged_in)
user_logged_out.connect(log_logged_out)
user_login_failed.connect(log_login_failed)

问题在于我没有找到获取user_login_failed信号的IP的方法，因为此函数在参数（https://docs.djangoproject.com/en/1.7/ref/contrib/auth/#module-django.contrib.auth.signals）中没有request。 credentials参数是仅包含username和password字段的字典。

我怎样才能获得此信号的IP地址？

非常感谢您的帮助。

不幸的是，user_login_failed不能将请求作为参数传递。

结帐django-axes - https://github.com/django-pci/django-axes/

它使用自定义视图装饰器来跟踪失败的登录信息。

您可以覆盖登录表单并在那里拦截它。它在那个阶段有要求。

import logging
from django.contrib.admin.forms import AdminAuthenticationForm
from django import forms

log = logging.getLogger(__name__)


class AuthenticationForm(AdminAuthenticationForm):
    def clean(self):
        # to cover more complex cases:
        # http://stackoverflow.com/questions/4581789/how-do-i-get-user-ip-address-in-django
        ip = request.META.get('REMOTE_ADDR')
        try:
            data = super(AuthenticationForm, self).clean()
        except forms.ValidationError:
            log.info('Login Failed (%s) from (%s)', self.cleaned_data.get('username'), ip)
            raise

        if bool(self.user_cache):
            log.info('Login Success (%s) from (%s)', self.cleaned_data.get('username'), ip)
        else:
            log.info('Login Failed (%s) from (%s)', self.cleaned_data.get('username'), ip)

        return data

要将其安装到网站中，您需要将其附加到django.contrib.admin.site.login_form

我建议你在App的ready（）方法中这样做：

from django.contrib.admin import site as admin_site

class Config(AppConfig):
    ...

    def ready(self):
        # Attach the logging hook to the login form
        from .forms import AuthenticationForm
        admin_site.login_form = AuthenticationForm

我刚刚发现在较新的Django版本（我正在使用2.1）中对此进行了更新，现在它在user_login_failed信号中包括了请求对象：

https://docs.djangoproject.com/en/2.1/ref/contrib/auth/#django.contrib.auth.signals.user_login_failed

Django记录user_login_failed信号的用户IP
