请放心获取数组对象名称

Question

JSON 示例

[
{
"PROPERTY1": [
{
"name": "String"
"value: 0 
},
{
"surname": "String",
"age": 20
}
]
},
{
"PROPERTY2": [
{
"name": "String"
"value: 1 
},
{
"surname": "String",
"age": 22
}
]
}
]

我想要一个数组[PROPERTY1，PROPERTY2]

如何使用最可靠的JSON路径提取器？

.extract().path("collect{it.value}"); //it's not working

下面是一个很长的机会，但这是我现在能想到的唯一解决方案

代码很容易解释，否则请告诉我，我会添加更多评论

String payload = "[{rn" + "       "PROPERTY1": [{rn" + "              "name": "String",rn"
+ "             "value": 0rn" + "           },rn" + "         {rn"
+ "             "surname": "String",rn" + "               "age": 20rn" + "            }rn"
+ "     ]rn" + "  },rn" + " {rn" + "      "PROPERTY2": [{rn"
+ "             "name": "String",rn" + "              "value": 1rn" + "           },rn"
+ "         {rn" + "              "surname": "String",rn" + "               "age": 22rn"
+ "         }rn" + "      ]rn" + "  }rn" + "]";
JSONArray array = new JSONArray(payload);
Iterator<Object> iterator = array.iterator();
ArrayList<String> keys = new ArrayList();
while (iterator.hasNext()) {
JSONObject jsonObject = (JSONObject) iterator.next();
keys.addAll(jsonObject.keySet());
}
System.out.println(keys);

确保将JSON负载提取为字符串

上述的响应将是[PROPERTY1, PROPERTY2]
