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,)
