django写用户登录判定并跳转制定页面的实例

1. 首先看要设置登陆的界面 book/view.py

@user_util.my_login #相当于 select_all=my_login(select_all)
def select_all(request):
 # 查询所有的书
 book_list = BookInfo.objects.all()
 # 返回
 return render(request, 'book/book_list.html', {'book_list': book_list})


@user_util.my_login #相当于 select_by_id=my_login(select_by_id)
def select_by_id(request,book_id):
 bookinfo=BookInfo.objects.get(id=book_id)
 return render(request,'book/book_detail.html',{'bookinfo':bookinfo})

@user_util.my_login 是在utils/user_utils.py里面写的装饰器

使用session判定是否登录：login_user_id = args[0].session.get(‘login_user_id')

#登陆用的装饰器

def my_login(func):
 def inner(*args,**kwargs):
  login_user_id = args[0].session.get('login_user_id')
  if login_user_id:
   return func(*args,**kwargs)
  else:
   return redirect(reverse('user:login'))
 return inner

2. 设置登录模块的界面

设置session键值对进行存储： request.session[‘login_user_id']=user[0].id

def login(request):
 #获取cookie
 remember_user_name=request.COOKIES.get('remember_user_name','')
 return render(request, "user/login.html",{'remember_user_name':remember_user_name})


def login_handler(request):
 # 判断请求方式
 if request.method == "GET":
  request_info = request.GET
 else:
  request_info = request.POST

 # 获取属性
 user_name = request_info.get("user_name",'').strip()
 user_pwd = request_info.get("user_pwd",'').strip()
 remember = request_info.get("remember")
 user_pwd = my_md5(user_pwd)
 user=User.objects.filter(name=user_name, pwd=user_pwd)
 #print(user[0].id)

 # 查询
 if len(user) != 0:
  #将登陆信息保存到session
  request.session['login_user_id']=user[0].id
  resp=HttpResponseRedirect(reverse("book:index"))
  #记住用户名
  if remember=='1':
   resp.set_cookie('remember_user_name',user_name,3600*24*7)
  else:
   resp.set_cookie('remember_user_name',user_name,0)
  return resp


  # 转发
  #return book_views.index(request)
  # 重定向
  #return HttpResponseRedirect(reverse("book:index"))

 else:

  return HttpResponseRedirect(reverse("user:login"))
