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
from django.conf.urls import url,include#引入include模块
from django.contrib import admin urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^a/', include("app1.urls")),
url(r'^b/', include("app2.urls")),
url(r'^c/', include("app3.urls")),
]
3.视图函数
user_info = {
'asd': {'pwd': ""},
'qwe': {'pwd': ""},
}
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})
