定义视图
from django.shortcuts import render,redirect
from django.contrib.auth.models import User
from django.contrib.auth import login,logout,authenticate
# Create your views here.
#登录
def loginView(request):
if request.method=="POST":
username=request.POST.get("username")
password=request.POST.get("password")
if User.objects.filter(username=username):
user=authenticate(username=username,password=password)
if user:
if user.is_active:
login(request,user)
# msg="登录成功"
request.session['status']=True
request.session['uname']=username
request.session.set_expiry(300)
return redirect("/index/")
else:
msg="用户名密码错误"
else:
msg="用户名不存在"
return render(request,"login.html",locals())
#注册
def regView(request):
if request.method=="POST":
username=request.POST.get("username")
password=request.POST.get("password")
email=request.POST.get("email")
if User.objects.filter(username=username):
msg="用户名已存在"
else:
user=User.objects.create_user(username=username,password=password,email=email)
msg="注册成功"
return redirect("/login/")
return render(request,"register.html",locals())
##主页
def index(request):
return render (request,"index.html",{"name":request.session.get('uname')})
添加路由
from django.contrib import admin
from django.urls import path
from user.views import loginView,regView,index
urlpatterns = [
path('admin/', admin.site.urls),
path('login/',loginView),
path('reg/',regView),
path('index/',index),
]
