Django之自帶認證

 

 

自帶登陸實例

class Account(models.Model):

    堡壘機帳戶

    user = models.OneToOneField(User, models.CASCADE)

models.py

LOGIN_URL = '/login/'

settings.py

from django.shortcuts import render,redirect,HttpResponse
from django.contrib.auth import authenticate,login,logout
from django.contrib.auth.decorators import login_required


# @login_required(login_url='/login/')  # 單獨添加login頁面的url
# 或在settings.py設置全局LOGIN_URL = '/login/'
@login_required
def index(request):
    return HttpResponse("成功登陸index頁面！")
    return render(request,"index.html")


def acc_login(request):
    error = ''
    if request.method == "POST":
        username = request.POST.get("username")
        password = request.POST.get("password")
        user = authenticate(username=username,password=password)  # 認證
        if user:
            login(request,user)  # 登陸
            return redirect(request.GET.get('next') or "/index/")  # 如有next字段，則跳轉到該url，不然index頁面
        else:
            error = "Wrong username or password"

    return render(request,"login.html",{"error":error})


@login_required
def acc_logout(request):
    logout(request)  # 登出
    return redirect("/login/")

views.py

 

結果：

單獨登陸login頁面

 

直接訪問index頁面，views裏的login_required裝飾器會跳轉到login頁面，同時會帶有?next=/index/字段的url

此處需在login函數裏配置

return redirect(request.GET.get('next') or "/index/")

 成功登陸
