URL = http://127.0.0.1:8000/polls

URL = http://127.0.0.1:8000/polls/1/

URL = http://127.0.0.1:8000/polls/1/results

这些所有网址都提供相同的映射相同的函数index（）。任何帮助将不胜感激

首先，要确保您遵循与您的Django版本相匹配的教程，确实非常重要。以下是Django 2.0和Django 1.11的链接。

您正在收到意外行为，因为您正在混合使用旧的url和新path语法。如果您使用的是Django 2.0，请更改导入并更新您的URL模式：

from django.urls import path

urlpatterns = [

    path('', views.index, name='index'),
    path('<int:question_id>/', views.detail, name='detail'),

    # ex: /polls/5/results/
    path('<int:question_id>/results/', views.results, name='results'),
    # ex: /polls/5/vote/
    path('<int:question_id>/vote/', views.vote, name='vote'),

]

如果您使用的是早期版本的Django，则需要使用正则表达式。例如，Django 1.11教程可以让你写：

from django.conf.urls import url

urlpatterns = [
    # ex: /polls/
    url(r'^$', views.index, name='index'),
    # ex: /polls/5/
    url(r'^(?P<question_id>[0-9]+)/$', views.detail, name='detail'),
    # ex: /polls/5/results/
    url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'),
    # ex: /polls/5/vote/
    url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'),
]

Answer 2

这是哪个版本的Django？您的网址格式看起来像2.0和旧版路由的混合。

您的空网址模式可能会匹配任何内容，因此不会调用其他路由。

对于Django 2.0 +做@Alasdair上面提到的更老的Django版本，如下所示：

urlpatterns = [
    url(r'^$', views.index, name='index'),
]

任何/ polls URL始终在views.py中调用index（）函数
