编写注册接口

1.编写注册接口

1.1 user/urls.py 中添加路由

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

1.2 user/views.py 中写注册视图函数

 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`

2.重写django认证

2.1 syl/settings.py 中指定自定义后端认证函数位置

 # 自定义验证后端 
 AUTHENTICATION_BACKENDS = ['user.utils.EmailAuthBackend']

2.2 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: 
     def authenticate(self, request, username=None, password=None): 
         try:
             user = User.objects.get(username=username) 
         except Exception as e: 
             user = None 
         if not user: 
             try:
                 user = User.objects.get(email=username) 
             except Exception as e: 
                 user = None 
         if user and user.check_password(password): 
             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

3.1 注册接口测试

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

3.2 登录接口测试

注: 认证时只能识别username,所以必须要在请求中携带username字段

http://192.168.56.100:8888/user/login/

3.3 获取用户列表接口测试

  • 访问接口

http://192.168.56.100:8888/user/user/5/

  • 测试自定义权限
 # 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,)
