Resolve paths with parameters in path.
Reverse (viewname,urlconf=None,args=None,Kwargs=None,current_app=None)
Book/views.py

Else: return redirect (reverse ('loose',kwargs= {' afrol 100)) def error (request,a,b): sum=a+b return HttpResponse ("sum: {}" .format (sum))
Book/urls.py
From django.urls import pathfrom. Import viewsurlpatterns = [path (', views.index,name='index'), path ('error//', views.error,name='loose'),]
General process: after starting the server, the index function in views will be called. Since there is no username parameter, it will be redirected to loose (the namespace of views.error), that is, the error function will be called. At this time, there are two parameters, Amemb, which can only be passed through reverse.
