“我的世界”统计Json - Java或Python

Question

我正在努力研究如何读取位于.json //< worldname >/stats/< UUID >.json中的统计信息。

Python版本

    import json
    
    json_file = open("C:/Users/<name>/AppData/Roaming/.minecraft/saves/<worldname>/stats/<UUID>.json")
    variables = json.load(json_file)
    json_file.close()
    
    print(variables["stats"])

Java版本：

import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;

import java.io.FileReader;
import java.io.IOException;
import java.io.Reader;
import java.util.Iterator;

public class Main {

    public static void main(String[] args) {

        JSONParser parser = new JSONParser();

        try (Reader reader = new FileReader("C:/Users/<name>/AppData/Roaming/.minecraft/saves/<worldname>/stats/<UUID>.json")) {

            JSONObject jsonObject = (JSONObject) parser.parse(reader);
            System.out.println(jsonObject);

            String stats = (String) jsonObject.get("stats");
            System.out.println(stats);

            //long age = (Long) jsonObject.get("age");
            //System.out.println(age);

            // loop array
            //JSONArray msg = (JSONArray) jsonObject.get("messages");
            //Iterator<String> iterator = msg.iterator();
            //while (iterator.hasNext()) {
            //    System.out.println(iterator.next());
            //}

        } catch (IOException e) {
            e.printStackTrace();
        } catch (ParseException e) {
            e.printStackTrace();
        }

    }

以下是文件中.json文件的大致样子：

    {'stats': {'minecraft:mined': {'minecraft:lily_of_the_valley': 1, 'minecraft:birch_leaves': 2, 'minecraft:crafting_table': 2, 'minecraft:grass': 1, 'minecraft:grass_block': 4, 'minecraft:oak_log': 10, 'minecraft:dirt': 6, 'minecraft:stone': 6, 'minecraft:oak_leaves': 3}, 'minecraft:killed': {'minecraft:pig': 4}, 'minecraft:picked_up': {'minecraft:stick': 2, 'minecraft:crafting_table': 3, 'minecraft:wooden_pickaxe': 1, 'minecraft:porkchop': 16, 'minecraft:oak_log': 10, 'minecraft:lily_of_the_valley': 1, 'minecraft:dirt': 19, 'minecraft:stone_axe': 1, 'minecraft:stone_pickaxe': 1, 'minecraft:oak_sapling': 2, 'minecraft:birch_sapling': 1, 'minecraft:oak_planks': 16, 'minecraft:cobblestone': 6}, 'minecraft:custom': {'minecraft:time_since_rest': 2832, 'minecraft:sprint_one_cm': 26594, 'minecraft:damage_taken': 360, 'minecraft:walk_one_cm': 10606, 'minecraft:mob_kills': 4, 'minecraft:drop': 1, 'minecraft:damage_dealt': 390, 'minecraft:swim_one_cm': 6359, 'minecraft:interact_with_crafting_table': 2, 'minecraft:fly_one_cm': 37248, 'minecraft:crouch_one_cm': 459, 'minecraft:play_one_minute': 6532, 'minecraft:deaths': 1, 'minecraft:sneak_time': 460, 'minecraft:walk_under_water_one_cm': 38, 'minecraft:jump': 293, 'minecraft:leave_game': 1, 'minecraft:walk_on_water_one_cm': 521, 'minecraft:time_since_death': 2811, 'minecraft:fall_one_cm': 9542}, 'minecraft:dropped': {'minecraft:birch_sapling': 1}, 'minecraft:crafted': {'minecraft:wooden_sword': 1, 'minecraft:oak_planks': 40, 'minecraft:crafting_table': 1, 'minecraft:stick': 8, 'minecraft:wooden_pickaxe': 1, 'minecraft:stone_pickaxe': 1, 'minecraft:stone_axe': 1}, 'minecraft:used': {'minecraft:oak_planks': 27, 'minecraft:wooden_pickaxe': 6, 'minecraft:stone_axe': 7, 'minecraft:wooden_sword': 13, 'minecraft:lily_of_the_valley': 1, 'minecraft:crafting_table': 2, 'minecraft:porkchop': 4}}, 'DataVersion': 2586}

因此，我想知道如何访问Java或Python中每一节中的每个变量，这将指导我编写统计读取器的路径。我正在为我的软件、设计和开发类编写一个统计读取器程序，我想不出如何进一步访问.json文件，只能访问"stats“元素中的内容。因此，一般来说，我希望程序能够将每个变量排序到它们的子标题中(“我的经验之谈:挖掘的”)，然后通过稍后的搜索在该子标题中获得变量，但我稍后会讲到，我只需要弄清楚如何读取和使用.json文件。谢谢大家给我的帮助，即使这是一个正确的方向的提示，为自己研究如何做到这一点，因为我不知道从哪里开始。

不管怎样，谢谢你们的帮助！

Answer 1

json.load()将json转换为python和list，因此您可以像处理常规python数据结构一样处理这些数据。(如果您需要更新这些内容，请考虑搜索python list和python dict。)

基本上，在你的例子中，你可以做的是：

stats = variables['stats']
# see what that gets you
print(stats)

mined = stats['minecraft:mined']
# once more, see what that is
print(mined)

# and so forth:
print(f"stone: {mined['minecraft:stone']}")

从那以后，你就可以自己继续了。:)

Answer 2

尽管它已经解决了，但我认为在Java中看到它对您也有好处。看看这个示例Java-Json。

为了简单起见，我将数据更改为{'stats': {'minecraft:mined': {'minecraft:lily_of_the_valley': 1}}}

这样做的方法如下：

  public static void main(String[] args) throws ParseException{

    String s = "{\"stats\": {\"minecraft:mined\": {\"minecraft:lily_of_the_valley\": 1}}}";

    JSONParser parser = new JSONParser();
    Object obj = parser.parse(s);

    JSONObject base = (JSONObject) obj;
    JSONObject stats = (JSONObject) base.get("stats");
    JSONObject minecraft_mined = (JSONObject) stats.get("minecraft:mined");
    long minecraft_lily_of_the_valley = (long) minecraft_mined.get("minecraft:lily_of_the_valley");
    System.out.println(base);
    System.out.println(stats);
    System.out.println(minecraft_mined);
    System.out.println(minecraft_lily_of_the_valley);


  }
