在路由配置中 里边都是正则来表示
净弄花里胡哨的东西 会两种就好了 就是配置访问的路径和参数吧
当一个用户通过网页发送一个请求给Django网站,Django执行过程如下:
-
首先访问项目下的settings.py文件中 ROOT_URLCONF = 'test1.urls'
-
执行项目包下的urls.py文件中的urlpatterns列表
-
执行应用包下的urls.py文件中的urlpatterns列表
-
根据匹配的url正则调用相应的视图函数/通用视图
-
如果没有匹配的正则,将会自动调用Django错误处理页面
url函数配置方式

方式1
#student/urls.py
#coding=utf-8
from django.conf.urls import url
from . import views
urlpatterns=[
url(r'^query$',views.queryAll)
]
#student/views.py
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.http import HttpResponse
from django.shortcuts import render
# Create your views here.
def queryAll(request):
return HttpResponse('hello world')
#访问地址
http://127.0.0.1:8000/student/query
-
方式2:位置传参
#student/urls.py
#coding=utf-8
from django.conf.urls import url
from . import views
urlpatterns=[
url(r'^query/(d{2})$',views.queryAll),
]
#student/views.py
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.http import HttpResponse
from django.shortcuts import render
# Create your views here.
def queryAll(request,sno):
print sno
return HttpResponse('hello world')
#访问地址
http://127.0.0.1:8000/student/query/12
-
方式3:关键字传参
urlpatterns=[
url(r'^query/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})/(?P<day>[0-9]{2})/$', views.queryAll),
]
def queryAll(request,year,day,month):
print year,month,day
return HttpResponse('hello world')
#访问地址
http://127.0.0.1:8000/student/query/2008/10/12/
-
方式4:加载其他映射文件
from django.conf.urls import include, url
urlpatterns = [
url(r'^community/', include('aggregator.urls')),
]
-
方式5:传参(参数名必须保持一致)
urlpatterns=[
url(r'^query/(?P<num1>d{3})/$',views.queryAll,{'hello':'123'}),
]
def queryAll(request,num1,hello):
print num1,hello
return HttpResponse('hello world')
#访问地址
http://127.0.0.1:8000/student/query/888/
#student/urls.py
from django.conf.urls import url
from . import views
urlpatterns=[
url(r'^query1/([0-9]{4})/$', views.queryAll, name='hello'),
url(r'^$', views.index_view),
]
#student/views.py
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.http import HttpResponse
from django.shortcuts import render
# Create your views here.
def queryAll(request,num1):
print num1
return HttpResponse('hello world')
#通过模板页面逆向访问
def index_view(request):
return render(request,'index.html')
#通过Python代码逆向访问
def index_view(request):
# return render(request,'index.html')
return HttpResponseRedirect(reverse('hello',args=(2018,)))
#templates/index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<a href="{% url 'hello' 2008 %}">访问</a>
</body>
</html>
