为 AWS::Serverless::Api GET 查询参数添加高级验证

Question

我正在尝试向

AWS::Serverless::Api

GET

请求、查询参数添加“高级”验证。

即

minimal

Int

参数的值：

{page}

应为 1。或枚举检查值

但是 Api 网关不处理此类验证，仅检查参数是否设置。

如何做到这一点？

我在 aws 文档中仅找到有关

body

验证（例如创建模型）的信息。但是，它不适用于查询参数

来自官方 aws qa：

不幸的是，我们没有选项对传入请求的标头和查询字符串参数进行高级验证。但是，在请求正文的情况下，我们可以利用 JSON 模式模型来验证有效负载结构。
