当前路径index与这些路径中的任何一个都不匹配。http://127.0.0.1:8001/index

Question

我通过cmd为Django设置网页。然而，我在访问127.0的索引页时遇到了问题。0.1:8001. 我试图更新URL。但是仍然有问题。

浏览器页面错误：找不到页面（404）请求方法：获取请求URL:http://127.0.0.1:8001/index使用barry中定义的URLconf。Django尝试了以下URL模式，顺序如下：

管理员/当前路径索引与这些路径中的任何一个都不匹配。

urls.py file:
"""{{ project_name }} URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/{{ docs_version }}/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path
from django.conf.urls import url
from sign import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('index/', views.index),
]

views.py
from django.shortcuts import render

# Create your views here.
def index(request):
return HttpResponse("Hello Django!")

Answer 1

您在路径模式中出错。与path、re\u path和url混淆。

看看DjangoURL-Path文档。

urlpatterns = [
    path('admin/', admin.site.urls),
    path('index/', views.index),
]
