如何从Django中的会话登录用户的uid？

I have implemented a registration/login/authentication system using this Django guide.

我已经使用这个Django指南实现了注册/登录/认证系统。

But, how would I access a user's information from my views so I can send the user's information to a template file?

但是，我如何从我的视图中访问用户的信息，以便将用户的信息发送到模板文件？

I want to be able to access a user's ID so I can submit a form with the user's ID attached to the form.

我希望能够访问用户的ID，以便我可以提交一个表格，其中附有表格的用户ID。

There is a django.contrib.auth.models.User object attached to the request; you can access it in a view via request.user. You must have the auth middleware installed, though.

有一个附加到请求的django.contrib.auth.models.User对象;您可以通过request.user在视图中访问它。但是，您必须安装auth中间件。

In case anyone wants to actually extract a user ID from an actual Session object (for whatever reason - I did!), here's how:

如果有人想从实际的Session对象中提取实际的用户ID（无论出于何种原因 - 我做过！），请按以下步骤操作：

from django.contrib.sessions.models import Session
from django.contrib.auth.models import User

session_key = '8cae76c505f15432b48c8292a7dd0e54'

session = Session.objects.get(session_key=session_key)
session_data = session.get_decoded()
print session_data
uid = session_data.get('_auth_user_id')
user = User.objects.get(id=uid)

This:

这个：

def view(request):
    if request.user.is_authenticated():
         user = request.user
         # do something with user

#4

An even easier way to do this is to install django-extensions and run the management command print_user_for_session.

更简单的方法是安装django-extensions并运行管理命令print_user_for_session。

And this is how they do it:

这就是他们这样做的方式：

In case hwjp solution doesn't work for you ("Data is corrupted"), here is another solution:

如果hwjp解决方案不适合你（“数据已损坏”），这是另一种解决方案：

import base64
import hashlib
import hmac
import json

def session_utoken(msg, secret_key, class_name='SessionStore'):
    key_salt = "django.contrib.sessions" + class_name
    sha1 = hashlib.sha1((key_salt + secret_key).encode('utf-8')).digest()
    utoken = hmac.new(sha1, msg=msg, digestmod=hashlib.sha1).hexdigest()
    return utoken


def decode(session_data, secret_key, class_name='SessionStore'):
    encoded_data = base64.b64decode(session_data)
    utoken, pickled = encoded_data.split(b':', 1)
    expected_utoken = session_utoken(pickled, secret_key, class_name)
    if utoken.decode() != expected_utoken:
        raise BaseException('Session data corrupted "%s" != "%s"',
                            utoken.decode(),
                            expected_utoken)
    return json.loads(pickled.decode('utf-8'))

s = Session.objects.get(session_key=session_key)
decode(s.session_data, 'YOUR_SECRET_KEY'))
