如何从查询中删除非SCHEMA参数

根据 fastify 4.0 docs ，默认选项，用于ajv包括removeAdcitional：true。我有一个querystring架构，当我发送带有架构中的param的查询时，我希望该参数被删除。但是没有这样的事情发生。模式本身是我的一些访问量的相当普通

querystring: {
    type: "object",
    properties: { … }
}

的类型数组，我也想删除任何其他值（通过enum指定的值之外。如何了吗

我实现

{
  '$schema': 'https://json-schema.org/draft/2020-12/schema',
  '$id': 'https://example.com/treatments.schema.json',
  title: 'Treatments',
  summary: 'Fetches treatments',
  description: 'Treatments are…',
  response: {},
  querystring: {
    type: 'object',
    additionalProperties: false,
    properties: {
      treatmentId: {
          type: "string",
          maxLength: 32,
          minLength: 32,
          description: "A 32 character string: treatmentId=388D179E0D564775C3925A5B93C1C407"
      },
      … <snipped> …
    }
  },
  tags: [ 'zenodeo' ]
}

？ http：// localhost：3010/v3/verresments？presenthing = foo给出一个错误{“ statuscode”：400，“错误”：“糟糕请求”，“不良请求”，“消息”：“ queryString：“ /presenthID不得少于32个字符“}（那很好

according to the fastify 4.0 docs, the default options for Ajv include removeAdditional: true. I have a queryString schema, and when I send a query with a param that is not in the schema, I expect that param to be removed. But no such thing happens. The schema itself is pretty run-of-the-mill

querystring: {
    type: "object",
    properties: { … }
}

Some of my params are of type array, and there too I would like any additional values (outside of those specified via enum to be removed. How can I achieve this?

update: I am adding the actual schema below (with some info snipped for brevity)

{
  '$schema': 'https://json-schema.org/draft/2020-12/schema',
  '$id': 'https://example.com/treatments.schema.json',
  title: 'Treatments',
  summary: 'Fetches treatments',
  description: 'Treatments are…',
  response: {},
  querystring: {
    type: 'object',
    additionalProperties: false,
    properties: {
      treatmentId: {
          type: "string",
          maxLength: 32,
          minLength: 32,
          description: "A 32 character string: treatmentId=388D179E0D564775C3925A5B93C1C407"
      },
      … <snipped> …
    }
  },
  tags: [ 'zenodeo' ]
}

I know the schema is being validated because http://localhost:3010/v3/treatments?treatmentId=foo gives an error {"statusCode":400,"error":"Bad Request","message":"querystring/treatmentId must NOT have fewer than 32 characters"} (that is good ????????) but the additionalProperties: false constraint is still not working because http://localhost:3010/v3/treatments?foo=bar gives no error and foo is also not removed from request.query (that is not good ????????)

使用removeAdtitional：true您仍然必须设置其他properties：false在您的架构上：

querystring: {
  type: "object",
  properties: { … },
  additionalProperties: false
}

请参阅 https://ajv.js.org/json-schema.html#additionalproperties

您还可以将默认行为更改为removeAdtitional：'ash hast''在这种情况下， t必须在模式上设置其他Properties：false。

请参阅此处的页面中的大约一半： https：//wwww.fastify .io/doc/最新/参考/验证和序列化/

With removeAdditional: true you must still set additionalProperties: false on your schema:

querystring: {
  type: "object",
  properties: { … },
  additionalProperties: false
}

See https://ajv.js.org/json-schema.html#additionalproperties

You can also change the default behavior to removeAdditional: 'all' in which case you don't have to set additionalProperties: false on your schema.

See about halfway down the page here: https://www.fastify.io/docs/latest/Reference/Validation-and-Serialization/
