Python Django-如何为GET请求创建/应用序列化程序？

通常，我会这样做以获取请求参数

name_input = request.GET.get("name",None)

但是，我只想限制

string

value或

int

value。此外，为了避免参数被发送为空，如下所示：

http://url?name=&age=12

如果我可以为

GET

请求应用

serializer

，我想这些问题可能会得到解决。但是我不知道怎么做。

创建一个包含两个（或更多）字段的序列化程序

然后通过将数据按如下方式传递到序列化程序来验证查询参数

serializer = QueryPramSerializer(data=request.GET)
serializer.is_valid(True)
print(serializer.validated_data)

serializer=QueryPramSerializer（data=request.GET）
序列化程序。是否有效（True）
打印（序列化程序。已验证的\u数据）

我假设您正在使用DRF，如果是这样，您可以使用而不是

请求。获取
您可以使用请求参数尝试此DRF
