django之session配置

一、session介绍

session默认可存在于表django_session中，类似于cookie，它是将值存储在服务端上，表中字段有session_key、session_data、expire_date

二、session示例

• views.py

def login_session(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:
            request.session["is_login"] = True
            request.session["user_name"] = user
            print(request.session["user_name"])
            obj = HttpResponse("登陆成功")
            return obj
        return HttpResponse('Error!')


def index_session(request):
    user = request.session.get("user_name")
    print('>>>',request.session.get("is_login"))
    print('>>>',request.session.get("user_name"))
    if request.session.get("is_login"):

        return render(request,'index.html',locals())
    else:
        return render(request, 'login.html',locals())

def loginout_session(request):
    print('>>>>',request.session.get("is_login"))
    print('>>>>',request.session.get("user_name"))
    request.session.flush()
    return redirect('/login_session/')

备注：包含三个函数分别是登录、验证、退出
