node.js 上招摇的可空字段
问题说明
我花了很多时间试图找到在 Node.JS 中创建 swagger 文档的解决方案.主库是 swagger-node，您可以在其中创建一个 swagger yaml 文件，然后将控制器添加到其中.它会自动在您的应用程序中提供 swagger ui 文档，并对请求进行验证响应您在 yaml 中指定的模型.
I've spent a bunch of time trying to find a solution for creating swagger docs in Node.JS. The main library is swagger-node, in which you create a swagger yaml file and then add your controllers to it. It automatically provides swagger ui docs in your app and does validation on the request & response against the models you specify in your yaml.
这很简洁，但是我有一个要求，我希望某些字段能够显式返回或接受 null 作为值，例如:
This is neat, however I have a requirement that some fields I want to explicitly be able to return or accept null as a value, for instance:
{
id: 123,
description: "string",
date_sent: null
}
我不想删除 date_sent 键，我想明确地将其声明为 null.
I don't want to delete the date_sent key, I want to explicitly state it as null.
swagger 规范不支持 anyOf 我相信 JSON 模式通常是这样做的.
The swagger spec does not support anyOf which is how JSON schema normally does this I believe.
我想知道是否有解决方法?也许某些可用于节点的库具有您可以添加的 x-nullable 供应商特定标志，或者以某种方式指定我的非必填字段都应该可以为空.
I'm wondering if there's a workaround? Perhaps some library available for node that has a x-nullable vendor specific flag you can add, or some way of specifying that my not-required fields should all be nullable.
我是否必须自己编写一些东西来获取我的 swagger 文件，然后在验证器中间件运行之前对其进行修改，还是有人可以建议一些解决方法?
Am I going to have to write something myself that takes my swagger file and then modifies it before the validator middleware runs, or is there some workaround someone can suggest?
