中间件可能是你最好的选择。我过去使用过这段代码,是在其他地方的代码段中进行了修改:
import re
from django.conf import settings
from django.contrib.auth.decorators import login_required
class RequireLoginMiddleware(object):
"""
Middleware component that wraps the login_required decorator around
matching URL patterns. To use, add the class to MIDDLEWARE_CLASSES and
define LOGIN_required_URLS and LOGIN_required_URLS_EXCEPTIONS in your
settings.py. For example:
------
LOGIN_required_URLS = (
r'/topsecret/(.*)$',
)
LOGIN_required_URLS_EXCEPTIONS = (
r'/topsecret/login(.*)$',
r'/topsecret/logout(.*)$',
)
------
LOGIN_required_URLS is where you define URL patterns; each pattern must
be a valid regex.
LOGIN_required_URLS_EXCEPTIONS is, conversely, where you explicitly
define any exceptions (like login and logout URLs).
"""
def __init__(self):
self.required = tuple(re.compile(url) for url in settings.LOGIN_required_URLS)
self.exceptions = tuple(re.compile(url) for url in settings.LOGIN_required_URLS_EXCEPTIONS)
def process_view(self, request, view_func, view_args, view_kwargs):
# No need to process URLs if user already logged in
if request.user.is_authenticated():
return None
# An exception match should immediately return None
for url in self.exceptions:
if url.match(request.path):
return None
# Requests matching a restricted URL pattern are returned
# wrapped with the login_required decorator
for url in self.required:
if url.match(request.path):
return login_required(view_func)(request, *view_args, **view_kwargs)
# Explicitly return None for all non-matching requests
return None
然后在settings.py中,列出你要保护的基本URL:
LOGIN_required_URLS = (
r'/private_stuff/(.*)$',
r'/login_required/(.*)$',
)
只要你的站点遵循要求身份验证的页面的URL约定,此模型就可以工作。如果这不是一对一的适合,你可以选择修改中间件以更紧密地适应你的情况。
我喜欢这种方法-除了消除了用@login_required
修饰符乱扔代码库的必要性之外-如果身份验证方案发生更改,你还有一个地方可以进行全局更改。
