我使用Django内部的User认证系统，本以为User.objects.create_user(username,password,email)加密及存入注册，使用user=auth.authenticate(username=username,password=password)解密并登陆，但反复auth.authenticate(）测试，均返回none,在csdn中看了别人的文章，使用 check_password(password,pwd)，还是返回none，查了UserManager下create_user()加密使用set_password()来加密的，经测试 check_password(password,pwd)不一致，可能是个bug，没有办法，只能在注册中加入user.set_password(password)，问题解决！代码如下：
注册：
class RegisterViews(View): def get(self,request): print("get") return render(request,‘register.html‘) def post(self,request): print("post") username = request.POST.get(‘user_name‘) password = request.POST.get(‘pwd‘) password1 = request.POST.get(‘cpwd‘) email = request.POST.get(‘email‘) allow = request.POST.get(‘allow‘) if not all([username,password,password1,email]): return render(request, ‘register.html‘, {‘errmsg‘:‘要素填写不全‘}) if allow != ‘on‘: return render(request, ‘register.html‘,{‘errmsg‘:‘用户使用协议未勾选‘}) if password != password1: return render(request, ‘register.html‘,{‘errmsg‘:‘两次密码输入不一致‘}) if not re.match(‘^[a-z0-9][\w\.\-]*@[a-z0-9\-]+(\.[a-z]{2,5}){1,2}$‘,email): return render(request, ‘register.html‘, {‘errmsg‘:‘邮箱格式有误‘}) try: User.objects.get(username=username) return render(request, ‘register.html‘, {‘errmsg‘: ‘用户已注册‘}) except ObjectDoesNotExist as e: user=User.objects.create_user(username,password,email) user.is_active=0 print("++++++++++++++") print(user.password) user.set_password(password) print(user.password) print("++++++++++++++") user.save() return render(reverse(‘user:login‘))
登陆：
class LoginViews(View): def get(self, request): return render(request, ‘login.html‘) def post(self,request): username=request.POST.get("username") password = request.POST.get("pwd") if not all([username,password]): return render(request, ‘login.html‘, {‘errmsg‘: ‘要素填写不全！‘}) print(username,password) #user=auth.authenticate(username=username,password=password) try: user=User.objects.get(username=username) except User.DoesNotExist: return render(request, ‘login.html‘, {‘errmsg‘: ‘用户不存在！‘}) pwd=user.password pwd1=make_password(password) print(pwd,pwd1) if check_password(password,pwd): print(‘ok‘) return render(request, ‘list.html‘) else: print(‘error‘) return render(request, ‘login.html‘, {‘errmsg‘: ‘用户名或者密码错误！‘})
解决方案二：
查资料发现只要在setting文件里面加上AUTHENTICATION_BACKENDS = [‘django.contrib.auth.backends.AllowAllUsersModelBackend‘]让他不自动关联数据库的is_active即可完美解决。
