定义视图
from django.shortcuts import render,redirectfrom django.contrib.auth.models import Userfrom 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']=Truerequest.session['uname']=usernamerequest.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
