为什么我的Django项目只能匹配一个URL

#filename: views.py

from django.shortcuts import render, render_to_response
from django.template import loader, Context, Template
from django.http import HttpResponse
from django.shortcuts import render_to_response

# Create your views here.

def index(req):
    t = loader.get_template('index.html')  #get template
    c = Context({'uname':'alen'})          #
    #html = t.render(c)
    #return HttpResponse(html)
    return HttpResponse(t.render(c))

def index1(req):
    t1 = Template('<h1>{{uname}},python.....index2</h1>')  #get template
    c2 = Context({'uname':'alen1'})          #
    #html = t.render(c)
    #return HttpResponse(html)
    return HttpResponse(t1.render(c2))

def index2(req):
    return render_to_response('index.html', {'uname':'csvt02'})

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'csvt02.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),

    url(r'^admin/', include(admin.site.urls)),
    url(r'^index/$', 'blog.views.index'),
    url(r'^index2/$', 'blog.views.index2'),
    url(r'^index1/$', 'blog.views.index1'),

)
