在django应用程序中全局存储oauth2访问令牌的最佳方式？

# settings.py
SESSION_ENGINE = 'django.contrib.sessions.backends.db'

# views.py
from django.shortcuts import redirect
from django.contrib.auth import login

def oauth2_callback(request):
    # 假设你已经获取了access_token
    access_token = 'your_access_token_here'
    request.session['access_token'] = access_token
    return redirect('home')

# settings.py
CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.PyMemcacheCache',
        'LOCATION': '127.0.0.1:11211',
    }
}

# views.py
from django.core.cache import cache

def get_access_token(request):
    access_token = cache.get('access_token')
    if not access_token:
        # 获取新的access_token并存储到缓存
        access_token = 'your_access_token_here'
        cache.set('access_token', access_token, timeout=3600)  # 设置过期时间
    return access_token

# 安装django-oauth-toolkit
# pip install django-oauth-toolkit

# settings.py
INSTALLED_APPS += ['oauth2_provider']

OAUTH2_PROVIDER = {
    'ACCESS_TOKEN_EXPIRE_SECONDS': 3600,
}

# views.py
from oauth2_provider.views.generic import ProtectedResourceView

class MyProtectedView(ProtectedResourceView):
    def get(self, request, *args, **kwargs):
        access_token = request.access_token.token
        # 处理请求
        return HttpResponse('Protected content')

# 安装redis和django-redis
# pip install redis django-redis

# settings.py
CACHES = {
    'default': {
        'BACKEND': 'django_redis.cache.RedisCache',
        'LOCATION': 'redis://127.0.0.1:6379/1',
        'OPTIONS': {
            'CLIENT_CLASS': 'django_redis.client.DefaultClient',
        }
    }
}

# views.py
from django.core.cache import cache

def get_access_token(request):
    access_token = cache.get('access_token')
    if not access_token:
        # 获取新的access_token并存储到Redis
        access_token = 'your_access_token_here'
        cache.set('access_token', access_token, timeout=3600)  # 设置过期时间
    return access_token
