    url(r'^admin/', include(admin.site.urls)),  
)

from django import forms  
from django.http import HttpResponse,HttpResponseRedirect  
from django.shortcuts import render_to_response  
  
class MyForm(forms.Form):  
    uname = forms.CharField(max_length = 14)   
  
def login(req):  
    if req.method == 'POST':  
        form = MyForm(req.POST)  
        if form.is_valid():  
            uname = form.cleaned_data['uname']  
            print uname  
            req.session['uname']=uname#保存  
            return HttpResponseRedirect('/index/')  
    else:  
        form = MyForm()  
    return render_to_response('login.html',{'form':form})  
  
def index(req):  
    if 'uname' in req.session:  
        uname = req.session['uname']#使用  
    else:  
        return HttpResponseRedirect('/login/')  
    return render_to_response('index.html',{'uname':uname})
