如何将此 NBT 数据字符串转换为有效的本机 javascript 对象或 JSON，为什么 chrome 控制台可以做到这一点？

所以我正在尝试获取它，以便您可以从 Minecraft 导出 NBT 数据，以便可以在我正在制作的在线工具中使用它。这是我尝试转换的 NBT 数据的示例：

Card"}'}],tier:1b}}}],id:"quark:variant_chest",x:-317,y:112,z:473}"

这直接来自 Minecraft 的“/data get”命令。

我已经创建了这个函数，它已经修复了很多问题：

function parseNBT(data) {
    return data
        // Convert "1b", "2b", etc., to plain integers (byte to int)
        .replace(/(\d+)b/g, '$1')

        // Convert "1.0f", "0.2f", etc., to plain numbers (float to number)
        .replace(/(\d*\.?\d+)f/g, '$1')

        // Convert "1.0d", "0.5d" (double) to plain numbers
        .replace(/(\d*\.?\d+)d/g, '$1')

        // Handle "uuid:[I;...]" - Convert to valid JSON array
        .replace(/uuid:\[I;([\d,-]+)\]/g, function (match, p1) {
            return `"uuid": [${p1}]`;
        })
}

我实际上可以将该函数返回的字符串放入 chrome 控制台的变量中，然后 chrome 控制台会将其解析为对象。

但在我的代码中我认为我只能使用 JSON.parse 并且在这种情况下需要将其格式化为 JSON。但这就是事情变得混乱的地方，原因如下：

  • 带有冒号的值，例如“the_vault:card”或“quark:variant_chest”。放置引号的通常方法是找到冒号，但在这种情况下，这会把事情搞砸。

  • 像这部分这样嵌套的东西： pool:[{config:'{"min":0.01,"max":0.01,"step":0.01}',tier:1b},{config:'{"min": 0.02,"最大":0.02,"步长":0.01}',层:2b},{config:'{"最小":0.03,"最大":0.03,"步长":0.01}',层:3b} ,{config:'{"min":0.04,"max":0.04,"step":0.01}',tier:4b},{config:'{"min":0.05,"max":0.05,"step “：0.01}'，等级：5b}]

我有两个问题：

  1. chrome 控制台是如何做到的？有没有办法像 chrome 控制台那样做？
  2. 如果没有，有人可以帮助我解决在尝试格式化字符串以更正 JSON 时出现的所有问题吗？

如果您需要更多信息，请告诉我。

chrome 控制台是如何做到的？有没有办法像 chrome 控制台那样做？

chrome 控制台将您的输入解析为 JavaScript 而不是 JSON，后者不太严格，并且允许例如不带引号的属性名称。您可以通过运行执行大致相同的操作：

eval(`"use strict";(${parseNBT(NBTString)})`)

请注意eval()

的安全隐患：除非您可以信任NBT字符串的来源，否则使用它是一个坏主意。

我建议浏览许多开源NBT解析器库，并且直接使用其中一个，或者查阅其源代码作为您自己实现的参考。
