渲染器：

from rest_framework.renderers import BrowsableAPIRenderer,AdminRenderer,HTMLFormRenderer,JSONRenderer

class TestView(APIView):

	renderer_classes = [JSONRenderer,BrowsableAPIRenderer, ] #建议只加这两个

	get(self,reuqest,*args,**kwargs):

		#获取数据  models.Role.objects.all()

		roles = self.get_queryset()

		pager_roles = self.paginate_queryset(roles)

		#序列化

		self.get_serializer(instance=pager_roles,many=True)

		return Response(ser.data)

全局配置：

"DEFAULT_RENDERER_CLASSES": ['',

		'rest_framework.renderers.JSONRenderer',

		'rest_framework.renderers.BrowsableAPIRenderer',

],

推荐写到settings里面
