如何从这个json字符串中获取columnID？

let jsonString = '{"columnID": "12345", "otherData": "someValue"}';
let jsonObject = JSON.parse(jsonString);
let columnID = jsonObject.columnID;
console.log(columnID); // 输出: 12345

import json

json_string = '{"columnID": "12345", "otherData": "someValue"}'
json_object = json.loads(json_string)
column_id = json_object['columnID']
print(column_id)  # 输出: 12345

import org.json.JSONObject;

public class Main {
    public static void main(String[] args) {
        String jsonString = "{\"columnID\": \"12345\", \"otherData\": \"someValue\"}";
        JSONObject jsonObject = new JSONObject(jsonString);
        String columnID = jsonObject.getString("columnID");
        System.out.println(columnID); // 输出: 12345
    }
}

using System;
using Newtonsoft.Json.Linq;

public class Program
{
    public static void Main()
    {
        string jsonString = "{\"columnID\": \"12345\", \"otherData\": \"someValue\"}";
        JObject jsonObject = JObject.Parse(jsonString);
        string columnID = jsonObject["columnID"].ToString();
        Console.WriteLine(columnID); // 输出: 12345
    }
}

import json

json_string = '{"columnID": "12345", "otherData": "someValue"}'
json_object = json.loads(json_string)

if 'columnID' in json_object:
    column_id = json_object['columnID']
    print(column_id)
else:
    print("Key 'columnID' not found in JSON object.")
