Question

我需要在执行某些视图期间通过令牌检查身份验证，而某些视图可以在不进行身份验证的情况下访问。那么，我如何制作中间件并从中排除一些视图。任何其他想法来解决这个问题是值得赞赏的。

我建议从Django提供的csrf middleware中获取灵感

events.js:183
      throw er; // Unhandled 'error' event
      ^

Error: listen EADDRINUSE localhost
    at Object._errnoException (util.js:1022:11)
    at _exceptionWithHostPort (util.js:1044:20)
    at Server.setupListenHandle [as _listen2] (net.js:1350:19)
    at listenInCluster (net.js:1408:12)
    at Server.listen (net.js:1503:5)
    at Object.<anonymous> (/media/shikhar/D/Study/git-test/node-express/index.js:30:8)
    at Module._compile (module.js:652:30)
    at Object.Module._extensions..js (module.js:663:10)
    at Module.load (module.js:565:32)
    at tryModuleLoad (module.js:505:12)

创建一个装饰器来包装您的视图

from django.utils.deprecation import MiddlewareMixin

class MyAuthenticationMiddleware(MiddlewareMixin):

    def process_view(self, request, callback, callback_args, callback_kwargs):

        if getattr(callback, 'my_exempt_flag', False):
            return None

        # Authentication goes here
        # Return None if authentication was successful
        # Return a HttpResponse with some error status if not successful

可以这样使用

from functools import wraps

def exempt_from_my_authentication_middleware(view_func):
    def wrapped_view(*args, **kwargs):
        return view_func(*args, **kwargs)
    wrapped_view.my_exempt_flag = True
    return wraps(view_func)(wrapped_view)
