示例1

 1 # Create your views here.
 2 user = "a"
 3 pwd = "a"
 4 def login(request):
 5     if request.method =="GET":
 6         return render(request,"login.html")
 7     elif request.method == "POST":
 8         u = request.POST.get("user")
 9         p = request.POST.get("password")
10         print(u)
11         print(p)
12         if u ==user and p ==pwd:
13             res = redirect("/index")
14             res.set_cookie('user',u,max_age=5)   #設置cookie，關閉瀏覽器cookie失效。max_age=5表示5秒后cookie失效，需要重新登錄
15             return res
16         else:
17             return  render(request,"login.html")
18 def index(request):
19     v = request.COOKIES.get("user")
20     if v:
21         return render(request,"index.html",{"current_user":v})
22     else:
23         return redirect("/login")

示例2 --- 基於裝飾器實現用戶認證

 1 user = "a"
 2 pwd = "a"
 3 
 4 def auth(func):
 5     def inner(reqeust,*args,**kwargs):
 6         v = reqeust.COOKIES.get('user')
 7         if not v:
 8             return redirect('/login')
 9         return func(reqeust, *args,**kwargs)
10     return inner
11 
12 def login(request):
13     if request.method =="GET":
14         return render(request,"login.html")
15     elif request.method == "POST":
16         u = request.POST.get("user")
17         p = request.POST.get("password")
18         if u ==user and p ==pwd:
19             res = redirect("/index")
20             res.set_cookie('user',u,max_age=5)   #設置cookie，關閉瀏覽器cookie失效。max_age=5表示5秒后cookie失效，需要重新登錄
21             return res
22         else:
23             return  render(request,"login.html")
24 @auth
25 def index(request):
26     v = request.COOKIES.get("user")
27     return render(request,"index.html",{"current_user":v})
