Python django中间件不工作，但如果我使用装饰，它会工作

运行python 2.7 Django 1.6这是我的代码：

我的设置.py 当我访问mysite.net/prev/或mysite.net/ric/时，url.matchrequest.path结果为False，因此不会调用NeedEfSelected。任何帮助都将不胜感激

解决了的！ 雅皮士！我自己解决了！我被误解了。这个中间件之前有另一个中间件。第一个，像这样，有一个错误： 返回self.orig_funcrequest，*args，**kwargs

它应该被“无返回”替换

因为中间件的工作逻辑。事实上，中间件是按顺序执行的，当所有测试都通过时返回None，或者当需要修改调用url的正常执行时返回HttpResponse。这是很好的解释

但我很快就浏览了它

你有没有检查设置中的内容。需要使用URL？您是否也检查了中间件是否被调用？非常感谢您的重播。settings.NEED_EF_URL是我在帖子中显示的URL；我猜中间件被调用了，因为如果我从pdb导入；pdb.set_跟踪；在两次返回之间，它停止。这让我不得不说url.matchrequest.path结果为False
