"""mysite URL Configuration The `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/1.11/topics/http/urls/ Examples: Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: url(r‘^$‘, views.home, name=‘home‘) Class-based views 1. Add an import: from other_app.views import Home 2. Add a URL to urlpatterns: url(r‘^$‘, Home.as_view(), name=‘home‘) Including another URLconf 1. Import the include() function: from django.conf.urls import url, include 2. Add a URL to urlpatterns: url(r‘^blog/‘, include(‘blog.urls‘)) """ from django.conf.urls import url from django.contrib import admin from app01 import views urlpatterns = [ url(r‘^admin/‘, admin.site.urls), # 视图为函数，定义URL url(r‘^index/‘, views.index), # 视图为类，定义URL url(r‘^home/‘, views.Home.as_view()), ]
URL有很多种类型，一个URL可以对应一个视图或者类，也可以用正则表达式的方法定义URL去匹配一类的URL

URL路由对应的名称 name=xxx，对URL路由关系进行命名，可以根据此名称生成自己想要的URL
通过URL对应的名称，action会自动匹配URL，修改URL的时候就不用每次修改完还要再改HTML中的URL了
url(r‘^index/‘, views.index, name="index"),
<form action="{% url "index" %}" method="POST"> <p><input type="text", name="user", placeholder="用户名"/></p> <p><input type="text", name="email", placeholder="邮箱"/></p> <input type="submit" value="提交"> </form>
mysite下的urls.py, namespace设置命名空间
from django.conf.urls import url from django.contrib import admin from django.conf.urls import include from app01 import views urlpatterns = [ url(r‘^admin/‘, admin.site.urls), url(r‘^a/‘, include(‘app01.urls‘, namespace="author")), url(r‘^b/‘, include(‘app01.urls‘, namespace="publisher")), ]
app01下的urls.py
from django.conf.urls import url from django.contrib import admin from app01 import views app_name = "app01" urlpatterns = [ url(r‘^index/‘, views.index, name=‘index‘), ]
views.py 在视图中使用， reverse反转时"namespace:name"
from django.shortcuts import render from django.shortcuts import HttpResponse # Create your views here. from django.urls import reverse def index(request): v = reverse("author:index") print(v) return HttpResponse("OK")
模板中使用
{% url namesapce: name%}
url(r‘^test/‘, views.index, name="test"), url(r‘^test/(\d+)/(\d+)/‘, views.index, name="test"), url(r‘^test/(?P<nid>\d+)/(?P<uid>\d+)/‘, views.index, name="test"),
{% url "test" %}
{% url "test" 1 2 %} # url为/test/1/2/ 参数要按照顺序
{% url "test" uid=9 nid=4 %} # url为/test/4/9/ 参数可以不按照顺序
url(r‘^test/‘, views.index, name="test"), url(r‘^test/(\d+)/(\d+)/‘, views.index, name="test"), url(r‘^test/(?P<nid>\d+)/(?P<uid>\d+)/‘, views.index, name="test"),
from django.urls import reverse def test(request, *args, **kwargs): v = reverse("index") return render(request, "test.html", {"url": v}) def test(request, *args, **kwargs): v = reverse("index", args=(1,2,)) return render(request, "test.html", {"url": v}) def test(request, *args, **kwargs): v = reverse("index", kwargs={"nid": "3", "uid": "4"}) return render(request, "test.html", {"url": v})
<form action="{{ url }}" method="POST"> <p><input type="text", name="user", placeholder="用户名"/></p> <p><input type="text", name="email", placeholder="邮箱"/></p> <input type="submit" value="提交"> </form>
from django.conf.urls import url from django.contrib import admin from app01 import views urlpatterns = [ url(r‘^admin/‘, admin.site.urls), url(r‘^index/‘, views.index, {"name": "root"}), ]
from django.shortcuts import render from django.shortcuts import HttpResponse # Create your views here. from django.urls import reverse def index(request, name): print(name) return HttpResponse("OK")
通过工程下面的urls.py去分发路由，将不同后缀的URL分发给不同的app
from django.conf.urls import url from django.contrib import admin from django.conf.urls import include urlpatterns = [ url(r‘^cmdb/‘, include("app01.urls")), url(r‘^monitor/‘, include("app02.urls")), ]
from django.conf.urls import url from django.contrib import admin from app01 import views urlpatterns = [ url(r‘^login/‘, views.login), ]
from django.conf.urls import url from django.contrib import admin from app02 import views urlpatterns = [ url(r‘^login/‘, views.login), ]
