Django 网址错误 : Unknown Specifier ? P\d

Question

我的 urls.py 文件是这样的:

urlpatterns = [
    url(r'^chat/(?P\d+)/$', views.chatindex_view, name='chatindex_view'),
]

我在执行 runserver 命令时遇到此错误:

in regex (regex, six.text_type(e))
django.core.exceptions.ImproperlyConfigured: "^chat/(?P\d+)/$" is not a valid regular expression: unknown specifier: ?P\d

Answer 1

那是无效的。您要获取的关键字参数在哪里？

url(r'^chat/(?P<id>\d+)/$', views.chatindex_view, name='chatindex_view'),
