python - '未找到 : /' error when linking app urls.py to project' s urls. py

Question

我在 Django 中链接到应用程序的 urls.py 文件时遇到问题

first_project urls.py

from django.contrib import admin
from django.urls import path
from django.conf.urls import include

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

first_app urls.py

from django.conf.urls import url
from first_app import views

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

错误

Django version 2.1.7, using settings 'first_project.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

Answer 1

您必须在 first_app 网址中添加尾部斜杠:

from django.contrib import admin
from django.urls import path
from django.conf.urls import include

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