python DRF获取参数介绍，pythondrf获取参数,DRF获取参数的方式

DRF获取参数的方式例如urlurl(r‘^demo/(?P<word>.*)/$‘, DemoView.as_view())在类视图中获取参数url:http://127.0.0.1:8000/demo/aaa/?bbb=bbb&ccc=ccc&ccc=CCCform:{"body":"body"}JSON:{"body":"body"}class DemoView(APIView):    def post(self, request, aaa):        aaa = aaa  # 获取url路径中的参数        bbb_str = request.query_params.get(‘bbb‘)  # 获取一个查询字符串的参数        ccc_list = request.query_params.getlist(‘ccc‘)  # 获取多个查询字符串参数        # 请求体中的参数        # 如果通过form表单传递,获取出来是QueryDict,通过.dict()转换成python的字典        form_body = request.data        # 如果通过JSON传递,获取出来就是字典,例如{‘body‘:‘body‘}        # json_body = request.data        print(aaa)        print(bbb_str)        print(ccc_list)        print(form_body.dict())        # print(json_body)        return Response({‘message‘: ‘OK‘})结果aaabbb[‘ccc‘, ‘CCC‘]{‘body‘: ‘body‘}URL路径参数/查询字符串不区分请求方式,GET/POST/PUT等都一样serializer中获取参数# viewclass DemoView(GenericAPIView):    serializer_class = DemoSerializer    def post(self, request, aaa):        serializer = self.get_serializer(data=request.query_params)        serializer.is_valid(raise_exception=True)        return Response({‘message‘: ‘OK‘})# serializerclass DemoSerializer(serializers.Serializer):    bbb = serializers.CharField()    ccc = serializers.ListField()  # List    def validate(self, attrs):        aaa = self.context[‘view‘].kwargs.get(‘aaa‘)  # 获取路径参数        bbb = attrs[‘bbb‘]  # 获取查询字符串        ccc = attrs[‘ccc‘]  # 获取以多个key相同的查询字符串        # 获取当前登陆的对象,需要根据场景进行使用        # user = self.context[‘request‘].user        print(aaa)        print(bbb)        print(ccc)        return attrs
