Django 实现用户认证set_Cookie

当用户通过认证时，set_Cookie(key, value)

request.Cookie.get(key) 如果key不为空，就说明验证通过，否者重新跳转回login登录页面

对于URL

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^tp1/', views.tp1),
    url(r'^user_list', views.user_list),
    url(r'^login', views.login),
    url(r'^Order/', views.Order.as_view()),
    url(r'^index/', views.index)
]

对于views文件

user = {'name':'dacengzi', 'password':123}
def login(request):
    if request.method == 'GET':  #如果进来的方式是GET，直接跳转
        return render(request, 'login.html')
    elif request.method == 'POST': #如果是POST，说明用户已经上传
        username = request.POST.get('username')  #获取用户名
        password = int(request.POST.get('password')) #获取密码
        current_time = datetime.datetime.utcnow()  #当前时间
        current_time = current_time + datetime.timedelta(seconds=5)  #当前时间推迟5秒

        if username == user['name'] and password == user['password']: #如果用户名和密码匹配
            req = redirect('/index/')

            req.set_cookie('correct', username, expires=current_time) #设置Cookie标志位
            return  req
        else:
            return render(request, 'login.html')
def auth(func):
    def inner(request, *args, **kwargs):
        answer = request.COOKIES.get('correct')  #接收验证所得的标志位
        if not answer:  #如果没有收到重新跳转回登录界面
            return render(request, 'login.html')
        else:  # 如果有就执行Order文件
            return func(request, *args, **kwargs)
    return inner
from django.utils.decorators import method_decorator
from django import  views
@method_decorator(auth, name='dispatch')  #给dispatch加装饰器，程序一进来就进行验证
class Order(views.View):
    def get(self, request):
        u = request.COOKIES.get('correct') #获取u，进行传递
        return render(request, 'index.html', {'u': u})

def index(request):
    return render(request, 'index.html')

对于login文件

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <form action="/login/" method="post">
    <input type="text" name="username">
    <input type="text" name="password">
    <input type="submit" value="提交">
    </form>
</body>
</html>
