如何在 Z93F725A07423FE21C889F6D348B 的 JSON 數組中找到特定的 JSON object
[英]How do you find a specific JSON object in a JSON array in java
問題描述
對於我的年終項目，我希望嘗試從 Z0ECD11C1D7A287401D148A23 文件中提取 IP 源和 IP 密度的“ip.src”和“ip.dst”：

我已經嘗試了下面的代碼，但這只會給我整個 JSON 文件，而不是我想要的特定值。 任何幫助將不勝感激。
package jsonproject;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import java.io.FileReader;
import java.util.Iterator;
public class Read20packets {
public static void main(String[] args) {
JSONParser parser = new JSONParser();
try {
Object obj = parser.parse(new FileReader("C:\\\\Users\\\\20 DNS packets.json"));
JSONObject jsonObject = (JSONObject) obj;
JSONArray dnsList = (JSONArray) jsonObject.get("records");
Iterator<JSONObject> iterator = dnsList.iterator();
while (iterator.hasNext()) {
System.out.println(iterator.next());
}
} catch (Exception e) {
e.printStackTrace();
}
}
}

謝謝大家，對於 ip 目的地，我認為我的答案如下：
Iterator<JSONObject> iterator = array.iterator();
while (iterator.hasNext()) {
JSONObject alpha = iterator.next();
source = (JSONObject) alpha.get("_source");
layers = (JSONObject) source.get("layers");
ip = (JSONObject) layers.get("ip");
ipdst = (String) ip.get("ip.dst");
ipsrc = (String) ip.get("ip.src");
System.out.println(ipdst);
}
} catch (Exception e) {
e.printStackTrace();
}
}
