django之cookie

一、介绍

二、创建UserInfo表

• models.py

class UserInfo(models.Model):
    name = models.CharField(max_length=32)
    pwd = models.CharField(max_length=32)

• 添加用户

from app01.models import UserInfo
UserInfo.objects.create(name='alex',pwd='123')
<UserInfo: UserInfo object (1)>
UserInfo.objects.create(name='egon',pwd='123')
<UserInfo: UserInfo object (2)>

三、设置cookie和读取cookie

def login(request):
    if request.method == "GET":
        return render(request,'login.html')
    else:
        user = request.POST.get("user")
        pwd = request.POST.get("pwd")
        user_obj = UserInfo.objects.filter(name=user,pwd=pwd).first()
        if user_obj:
            obj = HttpResponse("登陆成功")
            obj.set_cookie("is_login",True)
            obj.set_cookie("username",user)
            print(obj)
            return obj
        return HttpResponse('Error!')

def index(request):
    if request.COOKIES.get("is_login"):
        return render(request,'index.html')
    else:
        return render(request, 'login.html')
