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
@outer
def 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‘)

@outer
def test(request):
    return HttpResponse(‘test‘)

通过以上代码，我们可能使用sessions和cookies 做页面的验证，比如要想访问某个页面必须经过LOGIN验证，而且经过验证的可以下次访问的时候不用再验证了。
