http://www.itcast.cn/python/1/?i=1&p=new，只匹配“/python/1/”部分
url(r‘^([0-9]+)/$‘, views.detail, name=‘detail‘),
url(r‘^(?P<id>[0-9]+)/$‘, views.detail, name=‘detail‘),
from django.conf.urls import include, url
urlpatterns = [
url(r‘^‘, include(‘booktest.urls‘, namespace=‘booktest‘)),
]
请求http://www.itcast.cn/booktest/1/ 在sesstings.py中的配置： url(r‘^booktest/‘, include(‘booktest.urls‘, namespace=‘booktest‘)), 在booktest应用urls.py中的配置 url(r‘^([0-9]+)/$‘, views.detail, name=‘detail‘), 匹配部分是：/booktest/1/ 匹配过程：在settings.py中与“booktest/”成功，再用“1/”与booktest应用的urls匹配
新建views1.py
#coding:utf-8
from django.http import HttpResponse
def index(request):
return HttpResponse("你好")
在urls.py中修改配置
from . import views1
url(r‘^$‘, views1.index, name=‘index‘),

from django.http import HttpResponse
def index(request):
return HttpResponse(‘你好‘)
调用模板
from django.http import HttpResponse
from django.template import RequestContext, loader
def index(request):
t1 = loader.get_template(‘polls/index.html‘)
context = RequestContext(request, {‘h1‘: ‘hello‘})
return HttpResponse(t1.render(context))
from django.http import HttpResponse
from datetime import *
def index(request):
response = HttpResponse()
if request.COOKIES.has_key(‘h1‘):
response.write(‘<h1>‘ + request.COOKIES[‘h1‘] + ‘</h1>‘)
response.set_cookie(‘h1‘, ‘你好‘, 120)
# response.set_cookie(‘h1‘, ‘你好‘, None, datetime(2016, 10, 31))
return response
在views1.py中
from django.http import HttpResponse,HttpResponseRedirect
def index(request):
return HttpResponseRedirect(‘js/‘)
def index2(request,id):
return HttpResponse(id)
在应用的urls.py中增加一个url对象
url(r‘^([0-9]+)/$‘, views1.index2, name=‘index2‘),
from django.core.urlresolvers import reverse
def index(request):
return HttpResponseRedirect(reverse(‘booktest:index2‘, args=(1,)))
from django.http import JsonResponse
def index2(requeset):
return JsonResponse({‘list‘: ‘abc‘})
from django.shortcuts import render
def index(request):
return render(request, ‘booktest/index.html‘, {‘h1‘: ‘hello‘})
from django.shortcuts import redirect
from django.core.urlresolvers import reverse
def index(request):
return redirect(reverse(‘booktest:index2‘))
from django.shortcuts import *
def detail(request, id):
try:
book = get_object_or_404(BookInfo, pk=id)
except BookInfo.MultipleObjectsReturned:
book = None
return render(request, ‘booktest/detail.html‘, {‘book‘: book})
将settings.py中的DEBUG改为False
将请求地址输入2和100查看效果
from django.shortcuts import *
def index(request):
# list = get_list_or_404(BookInfo, pk__lt=1)
list = get_list_or_404(BookInfo, pk__lt=6)
return render(request, ‘booktest/index.html‘, {‘list‘: list})
将settings.py中的DEBUG改为False
像INSTALLED_APPS列表中添加： ‘django.contrib.sessions‘, 向MIDDLEWARE_CLASSES列表中添加： ‘django.contrib.sessions.middleware.SessionMiddleware‘,
from django.shortcuts import render, redirect
from django.core.urlresolvers import reverse
def index(request):
uname = request.session.get(‘uname‘)
return render(request, ‘booktest/index.html‘, {‘uname‘: uname})
def login(request):
return render(request, ‘booktest/login.html‘)
def login_handle(request):
request.session[‘uname‘] = request.POST[‘uname‘]
return redirect(reverse(‘main:index‘))
def logout(request):
# request.session[‘uname‘] = None
# del request.session[‘uname‘]
# request.session.clear()
request.session.flush()
return redirect(reverse(‘main:index‘))
主url：
from django.conf.urls import include, url
urlpatterns = [

]
应用url：
