Question

我有大量的JSON架构（不是JSON数据），并希望从中提取密钥。

我有如下所示的示例JSON模式。由于它的大小，我不能发布实际的模式。

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "definitions": {},
  "id": "http://example.com/example.json",
  "properties": {
    "checked": {
      "id": "/properties/checked",
      "type": "boolean"
    },
    "id": {
      "id": "/properties/id",
      "type": "integer"
    },
    "name": {
      "id": "/properties/name",
      "type": "string"
    },
    "price": {
      "id": "/properties/price",
      "type": "number"
    },
    "tags": {
      "id": "/properties/tags",
      "items": {
        "id": "/properties/tags/items",
        "type": "string"
      },
      "type": "array"
    }
  },
  "type": "object"
}

根据这个模式，我将如何能够提取密钥，如下面的JSON所示。下面的JSON对象是JSON数据，其中包含JSON模式中提到的所有密钥。

{
  "id": 1,
  "name": "A green door",
  "price": 12.5,
  "checked": false,
  "tags": [
    "home",
    "green"
  ]
}

我已经尝试了 JSON架构faker 但每次都会产生不同的数据。它甚至会产生空对象，而我无法手动修改JSON架构。我希望所有钥匙都在那里。例如，在上面的模式中，我应该能够提取下面的所有键。

ID
名称
价
检查
标签
- 家
- 绿色

我尝试了递归解决方案，但这没有帮助。我将如何构建JSON数据的任何解决方案，其中包含使用JavaScript

您可以尝试以下操作。我希望这可以帮助您实现用例。

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class regexExample {

    public static void main(String[] args){
       String jsonstr="{\n" +
               "  \"$schema\": \"http://json-schema.org/draft-04/schema#\",\n" +
               "  \"definitions\": {},\n" +
               "  \"id\": \"http://example.com/example.json\",\n" +
               "  \"properties\": {\n" +
               "    \"checked\": {\n" +
               "      \"id\": \"/properties/checked\",\n" +
               "      \"type\": \"boolean\"\n" +
               "    },\n" +
               "    \"id\": {\n" +
               "      \"id\": \"/properties/id\",\n" +
               "      \"type\": \"integer\"\n" +
               "    },\n" +
               "    \"name\": {\n" +
               "      \"id\": \"/properties/name\",\n" +
               "      \"type\": \"string\"\n" +
               "    },\n" +
               "    \"price\": {\n" +
               "      \"id\": \"/properties/price\",\n" +
               "      \"type\": \"number\"\n" +
               "    },\n" +
               "    \"tags\": {\n" +
               "      \"id\": \"/properties/tags\",\n" +
               "      \"items\": {\n" +
               "        \"id\": \"/properties/tags/items\",\n" +
               "        \"type\": \"string\"\n" +
               "      },\n" +
               "      \"type\": \"array\"\n" +
               "    }\n" +
               "  },\n" +
               "  \"type\": \"object\"\n" +
               "}";
        Pattern p = Pattern.compile("\"[\\w]+\":");
        Matcher m = p.matcher(jsonstr);
        String result="";
        while (m.find( )) {
            result = m.group().replace("\"","");
            result = result.replace(":","");
            System.out.println("Found value: " + result );
            }
    }
}

function myFunction() {
var str = { "$schema": "http://json-schema.org/draft-04/schema#",         "definitions": {}, "id": "http://example.com/example.json",  "properties": {    "checked": {      "id": "/properties/checked",      "type": "boolean"    },    "id": {      "id": "/properties/id",      "type": "integer"    },    "name": {      "id": "/properties/name",      "type": "string"    },    "price": {      "id": "/properties/price",      "type": "number"    },    "tags": {      "id": "/properties/tags",      "items": {        "id": "/properties/tags/items",        "type": "string"      },      "type": "array"    }  },  "type": "object"};
for (var key in str) {
       console.log(key);
       for(var key1 in key) {
       console.log(key);
       }
   }
}

这将获得密钥的关键。如果你想获得所有密钥，那么你需要编写递归方法。
