一：Auth模塊簡介
Auth模塊是Django自帶的用戶認證模塊：
我們在開發一個網站的時候，無可避免的需要設計實現網站的用戶系統。此時我們需要實現包括用戶註冊、用戶登錄、用戶認證、註銷、修改密碼等功能
Django內置了強大的用戶認證系統--auth，它默認使用 auth_user 表來存儲用戶數據。
鏈接數據庫後有自帶的auth_user表
二：Auth模塊常用方法
from django.contrib import auth from django.contrib.auth.decorators importviews.pylogin_required def auth_test(request): if request.method==‘POST‘: name=request.POST.get(‘name‘) pwd=request.POST.get(‘pwd‘) #做認證 user=auth.authenticate(request,username=name,password=pwd) # user=models.User.objece.filter(username=name,password=pwd).first()if user: # 做登錄 auth.login(request,user) return HttpResponse(‘登錄成功‘) else: return HttpResponse(‘登錄失敗‘) return render(request,‘index.html‘) def auth_test2(request): # print(request.user.username) # print(request.user.password)# print(type(request.user)) print(request.user) return render(request,‘auth_test.html‘) def auth_logout(request): auth.logout(request) return HttpResponse(‘註銷成功‘) @login_required def auth_createuser(request): # UserInfo.objects.create() # user1=UserInfo.objects.create_superuser(username=‘lqz1‘,password=‘lqz12345‘,email=‘[email protected]‘) # user2=UserInfo.objects.create_user(username=‘lqz2‘,password=‘lqz12345‘,email=‘[email protected]‘) # user = auth.authenticate(request, username=‘lqz1‘, password=‘lqz12345‘) # if user: # print(‘1111‘) # else: # print(‘222‘) if request.user.is_authenticated(): print(‘登錄了‘,request.user) else: print(‘沒有登錄‘,request.user) # user=request.user # 校驗密碼 # ret=user.check_password(‘lqz12345‘) # print(ret) # 設置密碼 # print(user) # ！！！！！！一定要save # user.set_password(‘lqz11111‘) # user.save() return HttpResponse(‘註冊成功‘)
