python - 如何在 python 中通过 jsonschema 过滤 json

Question

我在 Python 中有一个 json 文件和一个相关的 json-schema，我想从输入 json 文件中过滤掉所有不满足相对 json 模式的元素。

例如:

架构

{
  "type":"object",
  "$schema": "http://json-schema.org/draft-03/schema",
  "required":false,
  "properties":{
    "address": {
      "type":"object",
      "required":true,
      "properties":{
        "city": {
          "type":"string",
          "required":true
        },
        "houseNumber": {
          "type":"number",
          "required":false
        },
        "streetAddress": {
          "type":"string",
          "required":true
        }
      }
    },
    "phoneNumber": {
      "type":"array",
      "required":false,
      "items":
      {
        "type":"object",
        "required":false,
        "properties":{
          "number": {
            "type":"string",
            "required":false
          },
          "type": {
            "type":"string",
            "required":false
          }
        }
      }
    }
  }
}

Json 输入:

{
  "address":{
    "streetAddress": "21 2nd Street",
    "city":"New York",
    "houseNumber":12
  },
  "phoneNumber":
    [
    {
      "type":"home",
      "number":"212 555-1234",
      "description":"blabla"
    }
  ]
}

元素 "description":"blabla" 不存在于 json 架构中，必须进行过滤。

Json 输出:

{
  "address":{
    "streetAddress": "21 2nd Street",
    "city":"New York",
    "houseNumber":12
  },
  "phoneNumber":
    [
    {
      "type":"home",
      "number":"212 555-1234"
    }
  ]
}

我找到了这个 https://github.com/alank64/json-schema-filter但它适用于 javascript。您是否知道任何能够在 Python 中执行此操作的脚本？
