Question

我很困惑为什么URL调度程序试图寻找一个空路径虽然为它指定了一个url？这是否意味着它无法找到指定的URL，因此试图找到默认值。

当我尝试POST并且HttpResponseRedirect搜索空路径而不是遵循指定路径时，会发生这种情况。假设另一个。

使用Django版本：2.0

提前致谢！

main / urls.py（ROOT_URLCONF）

from django.contrib import admin

urlpatterns = [
   path('admin/', admin.site.urls),
   path('app/', include('shorterner.urls'))
]

shortner / urls.py

您似乎正在将表单数据发送到此路径/。但是你还没有在main/urls.py中定义该路线。
