cookie实现用户登录验证
cookie实现用户登录验证
1，
INSTALLED_APPS中注册app03
2，在主程序中新建映射关系到app3的url中
1 from django.conf.urls import url,include#引入include模块 2 from django.contrib import admin 3 4 urlpatterns = [ 5 url(r'^admin/', admin.site.urls), 6 url(r'^a/', include("app1.urls")), 7 url(r'^b/', include("app2.urls")), 8 url(r'^c/', include("app3.urls")), 9 ]
3.视图函数
user_info = { 'asd': {'pwd': "123123"}, 'qwe': {'pwd': "666123"}, } def login(request): if request.method == "GET": return render(request, 'test3login.html') # 用户请求方式为get时，返回test3login.html信息 if request.method == "POST": # 如果用户为post请求时，获取用户数据 u = request.POST.get('username') p = request.POST.get('pwd') dic = user_info.get(u) if not dic: return render(request, 'test3login.html') if dic['pwd'] == p: res = redirect('/c/test3/') res.set_cookie('username111') # res.set_cookie('username111',u,max_age=10) # import datetime # current_date = datetime.datetime.utcnow() # current_date = current_date + datetime.timedelta(seconds=5) # res.set_cookie('username111',u,expires=current_date) res.set_cookie('username111', u) res.set_cookie('user_type', "f", httponly=True) return res else: return render(request, 'test3login.html') def index(reqeust): # 获取当前已经登录的用户 v = reqeust.COOKIES.get('username111') return render(reqeust,'index.html',{'current_user': v})
