本文實(shí)例講述了django 框架實(shí)現(xiàn)的用戶注冊(cè)、登錄、退出功能。分享給大家供大家參考，具體如下：

1 用戶注冊(cè)：

from django.contrib import auth
from django.contrib.auth.models import User
from django.views.decorators.csrf import csrf_exempt
from django.http import HttpResponseRedirect
# 用戶注冊(cè)
@csrf_exempt
def register(request):
  errors = []
  account = None
  password = None
  password2 = None
  email = None
  CompareFlag = False
  if request.method == 'POST':
    if not request.POST.get('account'):
      errors.append('用戶名不能為空')
    else:
      account = request.POST.get('account')
    if not request.POST.get('password'):
      errors.append('密碼不能為空')
    else:
      password = request.POST.get('password')
    if not request.POST.get('password2'):
      errors.append('確認(rèn)密碼不能為空')
    else:
      password2 = request.POST.get('password2')
    if not request.POST.get('email'):
      errors.append('郵箱不能為空')
    else:
      email = request.POST.get('email')
    if password is not None:
      if password == password2:
        CompareFlag = True
      else:
        errors.append('兩次輸入密碼不一致')
    if account is not None and password is not None and password2 is not None and email is not None and CompareFlag :
      user = User.objects.create_user(account,email,password)
      user.save()
      userlogin = auth.authenticate(username = account,password = password)
      auth.login(request,userlogin)
      return HttpResponseRedirect('/blog')
  return render(request,'blog/register.html', {'errors': errors})

2 用戶登錄：

@csrf_exempt
def my_login(request):
  errors =[]
  account = None
  password = None
  if request.method == "POST":
    if not request.POST.get('account'):
      errors.append('用戶名不能為空')
    else:
      account = request.POST.get('account')
    if not request.POST.get('password'):
      errors = request.POST.get('密碼不能為空')
    else:
      password = request.POST.get('password')
    if account is not None and password is not None:
      user = auth.authenticate(username=account,password=password)
      if user is not None:
        if user.is_active:
          auth.login(request,user)
          return HttpResponseRedirect('/blog')
        else:
          errors.append('用戶名錯(cuò)誤')
      else:
        errors.append('用戶名或密碼錯(cuò)誤')
  return render(request,'blog/login.html', {'errors': errors})

3 用戶退出：

def my_logout(request):
  auth.logout(request)
  return HttpResponseRedirect('/blog')

URL：

urlpatterns = [
  url(r'^$', views.index, name='index'),
  url(r'^p/(?P<article_id>[0-9]+)/$', views.detail,name='detail'),
  url(r'^register/$',views.register, name='register'),
  url(r'^login/$',views.my_login, name='my_login'),
  url(r'^logout/$',views.my_logout, name='my_logout'),
]
