1. user/urls.py 中添加路由

   • urlpatterns = [
     	path('register/', views.RegisterView.as_view()), # 注册视图, /user/register/
     ]
     

2. user/views.py 中写注册视图函数

   • import datetime
     import random
     
     
     class RegisterView(APIView):
         """
         用户注册, 权限是: 匿名用户可访问
         """
         # 自定义权限类
         permission_classes = (AllowAny,)
     
         def post(self, request):
             """
             接收邮箱和密码, 前端校验两遍一致性, 注册成功后返回成功, 然后用户自行登录获取token
             1. 随机用户名
             2. 生成用户
             3. 设置用户密码
             4. 保存用户
             :param request:
             :return: {'code':0,'msg':'注册成功'}
             """
             email = request.data.get('email')
             passwrod = request.data.get('password')
             if all([email, passwrod]):
                 pass
             else:
                 return Response({'code': 9999, 'msg': '参数不全'})
             rand_name = self.randomUsername()
             user = User(username=rand_name, email=email)
             user.set_password(passwrod)
             user.save()
             return Response({'code': 0, 'msg': '注册成功'})
     
         def randomUsername(self):
             """
             生成随机用户名: 格式: SYL + 年月日时分 + 5位随机数
             :return:
             """
             d = datetime.datetime.now()
             base = 'SYL'
             time_str = '%04d%02d%02d%02d%02d' % (d.year, d.month, d.day, d.hour,
                                                  d.minute)
             rand_num = str(random.randint(10000, 99999))
             return base + time_str + rand_num
     

重写django认证

1. syl/settings.py 中指定自定义后端认证函数位置

   • AUTHENTICATION_BACKENDS = ['user.utils.EmailAuthBackend']
     

2. user/utils.py 中重写认证函数

   • # 以前使用username进行用户验证，现在修改成email进行验证
     class EmailAuthBackend:
         # 自定义权限类
         # permission_classes = (MyPermission,)
         # 自定义认证类, 自定义会覆盖全局配置
         # authentication_classes = (JSONWebTokenAuthentication,)
     
         def authenticate(self, request, username=None, password=None):
             try:
                 user = User.objects.get(username=username)
             except Exception as e:
                 print(e)
                 user = None
             if not user:
                 try:
                     user = User.objects.get(email=username)
                 except Exception as e:
                     print(e)
                     user = None
             if user and user.check_password(password):
                 # jwt_response_payload_handler()
                 return user
             else:
                 return None
     
         def get_user(self, user_id):
             try:
                 return User.objects.get(pk=user_id)
             except User.DoesNotExist:
                 return None
     

3. .注册用户 & 测试登录

   1. 注册接口测试

      • http://192.168.56.100:8888/user/register/
        

      • 

   2. 获取用户列表接口测试

      •
