Django 使用SESSION和COOKIES做页面的验证

1.URLS

urlpatterns = [    url(r‘^admin/‘, admin.site.urls),    url(r‘^index/‘,views.index),    url(r‘^login/‘,views.login),    url(r‘^test/‘,views.test),]

2.Views 代码

from django.shortcuts import render,redirect,HttpResponse

# Create your views here.‘‘‘def login(request):    if request.method == ‘POST‘:        username=request.POST[‘user‘]        password=request.POST[‘pwd‘]        if username ==‘Freeman‘ and password == ‘redhat‘:            request.session[‘login‘] =True            return  redirect(‘/index/‘)        else:            return  render(request,‘login.html‘)    else:        return render(request,‘login.html‘)def index(request):    is_login = request.session.get(‘login‘,False)    if is_login:        return  HttpResponse(‘Say hi here is index‘)    else:        return redirect(‘/login/‘)    #return render(request,‘index.html‘)def logout(request):    del request.session[‘login‘]    return redirect(‘login‘)‘‘‘def outer(func):    print (‘start --------------------------------‘)    def wrap(request,*arg,**kwargs):        is_login=request.session.get(‘login‘,None)        if is_login:            ret = func(request,*arg,**kwargs)            return ret        else:            return redirect(‘/login/‘)    return wrap@outerdef index(request):    return HttpResponse(‘index‘)

def login(request):    if request.method == ‘POST‘:        username=request.POST[‘user‘]        password=request.POST[‘pwd‘]        if username ==‘Freeman‘ and password == ‘redhat‘:            request.session[‘login‘] =True            return  redirect(‘/index/‘)        else:            return  render(request,‘login.html‘)    else:        return render(request,‘login.html‘)

@outerdef test(request):    return HttpResponse(‘test‘)
