如何使用Django DRF viewset.Viewsets添加自定义动作函数？

from rest_framework import viewsets

class MyViewSet(viewsets.ViewSet):
    # 添加自定义动作函数
    def my_action(self, request):
        # 自定义动作函数的逻辑代码
        pass

from rest_framework.decorators import action

class MyViewSet(viewsets.ViewSet):
    @action(methods=['get'], detail=False)
    def my_action(self, request):
        # 自定义动作函数的逻辑代码
        pass

from rest_framework.response import Response

class MyViewSet(viewsets.ViewSet):
    @action(methods=['get'], detail=False)
    def my_action(self, request):
        # 自定义动作函数的逻辑代码
        data = {'message': 'This is a custom action'}
        return Response(data)

from django.urls import path
from .views import MyViewSet

router = routers.DefaultRouter()
router.register(r'myviewset', MyViewSet, basename='myviewset')

urlpatterns = [
    # 其他URL配置
    path('api/', include(router.urls)),
]
