前端:(login 页面)
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <div> <form action="/login/" method="post"> <p> <span>用户名：</span> <input type="text" name="user"> <span>密码：</span><input type="password" name="pwd"> <input type="submit" value="提交"> </p> </form> </div> </body> </html>
前端:(index页面)
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1> 欢迎登录......... </h1> </body> </html>
URL：
from django.contrib import admin from django.urls import path from django.conf.urls import url from app01 import views urlpatterns = [ path(‘admin/‘, admin.site.urls), url(‘^login/‘, views.login), url(‘^index/‘, views.index), ]
后端：
from django.shortcuts import render,HttpResponse,redirect # Create your views here. def login(request): print(request.COOKIES) print(request.session) if request.method == "POST": u = request.POST.get("user",None) p= request.POST.get("pwd",None) if u == "root" and p == "123": # cookie的方式: # ret = redirect("/index/") # #设置cookie数值 # ret.set_cookie("name","123",10) # return ret #session方式 request.session["info_login"]=True request.session["user"] = u return redirect("/index/") else: redirect("/login/") return render(request,"login.html") def index(request): #cookie # if request.COOKIES.get("name",None): # print("index") # return render(request,"index.html") #session if request.session.get("info_login",None): name = request.session.get("user") return render(request,"index.html") #session 默认存放在数据库中。 else: return redirect("/login/")
--------------------------------------------------------------------------------------------------------------------------------------------------------
装饰器的方式：
from django.shortcuts import render,redirect,HttpResponse # Create your views here. def aut(fum): def log(request,*args,**kwargs): if request.COOKIES.get("user",None): return fum(request,*args,**kwargs) else: return redirect("/login/") return log def login(request): if request.method == "POST": u = request.POST.get("user", None) p = request.POST.get("pwd", None) if u == "root" and p == "123": ret = redirect("/index/") # ret.set_cookie("user", u) ret.set_signed_cookie("user",u,salt="abcd") return ret else: return redirect("/login/") return render(request,"login.html") @aut def index(request): return HttpResponse("OK")
