rest_framework自带增删改查四种方法
查询：get：Carousel.objects.all() --->method:'GET'
增加：post：carousel.save()       --->method:'POST(data)',request.data.get()
删除：delete：Carousel.objects.filter(id=id).delete() --->method:'DELETE(params)',request.GET.get()
修改：put：carousel.save()        --->method:'PUT(data)',request.data.get()
