我們的登錄驗證是瀏覽器級別的驗證還有用戶級別的驗證,

使用我們的django內部的數據庫表,auth_user,然後使用它內部的一些模塊和方法,

在視圖函數裏面需要引入模塊寫邏輯代碼:

from django.shortcuts import render,redirect

# Create your views here.

from django.contrib import auth
from django.contrib.auth.models import User
# 以上兩句是固定模式,
def log_in(request):

    if request.method=="POST":
        user=request.POST.get("user")
        pwd=request.POST.get("pwd")
        # 驗證成功，返回user對象，否則返回None
        user=auth.authenticate(username=user,password=pwd)

        if user:
            auth.login(request,user)  # session寫操作
            return redirect("/index/")


    return render(request,"login.html")


def index(request):
    print(request.user)
    print(type(request.user))

    # if not request.user.id:
    #     return redirect("/login/")

    # user=request.user
    # if not user.is_authenticated():return redirect("/login/")

    return render(request,"index.html",locals())


def log_out(request):
    auth.logout(request)
    return redirect("/login/")


def reg(request):
      User.objects.create_user(username="egon123",password="1234")

      return redirect("/login/")
 

在驗證中我們有幾種狀態固定語句:

登錄:

user1=auth.authenticate(username=user,password=pwd)

auth.login(request,user1) # 類似於session寫操作

==============================================================

退出登錄狀態:

auth.logout(request)

request.session.flush()

=================================================

驗證 :

user.is_authenticated()

登錄狀態時,返回True,否則返回False

===================================================

創建用戶:

user.objects.create_user(username=‘egon‘,password=‘1234‘)
