增加认证方法

from django.contrib import auth
def login(request):
if request.method == 'POST':
#获取表单用户密码
username = request.POST.get('username', '')
password = request.POST.get('password', '')
#获取的表单数据与数据库进行比较
user = auth.authenticate(username = username,password = password)
if user:
#比较成功，跳转index
auth.login(request,user)
request.session['username'] = username
return HttpResponseRedirect('/')
else:
#比较失败，还在login
return render(request, 'login.html')
else:
return render(request, 'login.html')

{% if user.is_authenticated %}
<p>Welcome, {{ user.username }}. Thanks for logging in.</p>
{% else %}
<p>Welcome, new user. Please log in.</p>
{% endif %}
