项目中验证用户名+手机号是否存在

2 接口

2.1 user/views.py

class RegCountView(APIView):
    # 注册时需要验证的用户名和手机号是否使用

    # 自定义权限类
    permission_classes = (AllowAny,)
    def post(self, request):
        # 接收参数：验证的内容type：username/phone     data:'用户名' 或者：'手机号'
        datatype = request.data.get('type')     # user
        data = request.data.get('data')
        if not all([data, datatype]):
            return Response({'code': '999', 'msg':'参数不完整'})
        if datatype == 'username':
            count = User.objects.filter(username=data).count()
        if datatype == "phone":
            count = User.objects.filter(phone=data).count()

        return Response(
            {'code':0, 'msg':'查询成功', 'data': {'type': datatype, 'count':count}}
        )

2.2 user/urls.py

from django.urls import include, path
from rest_framework.authtoken.views import obtain_auth_token
from user import views
from rest_framework.routers import SimpleRouter, DefaultRouter
from rest_framework_jwt.views import obtain_jwt_token, refresh_jwt_token
# 自动生成路由方法, 必须使用视图集
# router = SimpleRouter() # 没有根路由 /user/ 无法识别
router = DefaultRouter() # 有根路由
router.register(r'user', views.UserViewSet)
urlpatterns = [
    path('index/', views.index),    # 函数视图
    path('login/', obtain_jwt_token), # 获取token，登录视图
    path('refresh/', refresh_jwt_token), # 刷新token
    path('api-auth/', include('rest_framework.urls',namespace='rest_framework')), # 认证地址
    path('register/', views.RegisterView.as_view()), # 注册视图, /user/register/
    path('count/', views.RegCountView.as_view()),		# 验证用户名&手机号是否注册过
