django自带的登录验证功能

django自带的验证机制

from django.shortcuts import render, redirect
from django.contrib.auth import authenticate, login, logout  #登入和登出

from django.contrib.auth.decorators import login_required  # 验证用户是否登录

def acc_login(request):


    if request.method == "POST":
        username = request.POST.get("username")
        password = request.POST.get("password")

        user = authenticate(username=username,password=password)  # 类型为<class 'django.contrib.auth.models.User'>

        # print(type(models.Customer.objects.get(name="赵凡")))
        # print(user,type(user))
        if user:

            login(request,user)  # 验证成功之后登录
            return  redirect('/crm')

    return render(request, "login.html")


def acc_logout(request):

    logout(request)  # 登出

    return redirect("/login")

必须登录之后才能访问页面

from django.contrib.auth.decorators import login_required

@login_required  # 加上这个装饰器就是限制必须登录才能执行这个函数
def dashboard(request):
    print(request.user)

    return render(request, "crm1/dashboard.html")

如果加了@login_required,页面跳转会有问题,解决方法如下

在setting里追加一下内容/login/跟URL是一致的

LOGIN_URL = "/login/"
