将数据转换为JSON格式的最快方法是什么？

Question

我需要将一些数据转换成JSON格式，以便在我的React.js项目中使用这些数据。

目前的数据格式如下：

["'Your Cut'"] = {
    ["id"]                  = 3400,
    ["tier"]                = 1,
    ["type"]                = {"Distributed"},
    ["limit"]               = "Only granted by {{cai|Death from Below|Pyke}}.",
    ["maps"] = {
        ["sr"]              = true,
        ["ha"]              = true,
        ["nb"]              = true,
        ["tt"]              = true,
        ["cs"]              = false,
    },
    ["effects"] = {
        ["consume"]         = "Grants {{g|text=*none*}}{{pp|100;112;140;176;220;274;300|-7+x;0+|type=target's kill bounty|color=gold}}, increased by {{g|100}} for [[First Blood]]. '''Can be used while [[dead]].'''",
    },
},
["Abyssal Mask"] = {
    ["id"]                  = 8020,
    ["tier"]                = 3,
    ["maps"] = {
        ["sr"]              = true,
        ["ha"]              = true,
        ["nb"]              = true,
    },
    ["menu"] = {
        ["tank"]            = true,
    },
    ["stats"] = {
        ["ah"]              = 10,
        ["hp"]              = 450,
        ["mr"]              = 35,
    },
    ["effects"] = {
        ["pass"] = {
            ["name"]        = "Unmake",
            ["unique"]      = true,
            ["description"] = "Enemy champions within {{tt|550 units|center to edge}} of you become cursed, reducing their {{as|magic resistance by 5}} {{as|(+ {{fd|1.2}}% '''bonus''' health)}}, capped at a reduction of {{as|25 magic resistance}}. Gain {{as|9 '''bonus''' magic resistance}} per cursed enemy.",
        },
    },
    ["recipe"]              = {"Kindlegem", "Spectre's Cowl"},
    ["buy"]                 = 2700,
},
["Aegis of the Legion"] = {
    ["id"]                  = 3105,
    ["tier"]                = 2,
    ["maps"] = {
        ["sr"]              = true,
        ["ha"]              = true,
        ["nb"]              = true,
    },
    ["menu"] = {
        ["tank"]            = true,
        ["support"]         = true,
    },
    ["stats"] = {
        ["ah"]              = 10,
        ["armor"]           = 30,
        ["mr"]              = 30,
    },
    ["recipe"]              = {"Null-Magic Mantle", "Cloth Armor"},
    ["buy"]                 = 1400,
},

..。再等6000条线路。

我尝试过在中使用REGEX替换，但是它停止了响应并使程序崩溃。

什么是正确的方法来处理这个问题？

我应该用某种语言编写一个脚本来转换数据吗？如果是这样的话，我应该使用REGEX还是有更聪明的方法？

谢谢

您需要知道输入的确切语法规则。例如，如果字符串文本可能包括换行符或双引号(分隔符)等特殊字符，以及如何编码。

但是，对于给出的示例，我看到需要执行以下转换才能使其有效的JSON：

键名周围的方括号应该去掉braces

• Trailing

• ，终止数组的大括号应该转换为方括号

• ，整个输入应该用一对花括号(在对象文字的最后一个键之后)包装起来，应该删除

。

看到输入结构，我做了几个假设，包括：

在单行上打开和关闭

• 数组；
• 数组不是在单独的行上定义；
• 键名和字符串值总是双引号。
• 不执行字符串内插(双大括号保持不变)

下面是JavaScript中该转换的一个可运行的实现，它为您提供的示例输入生成一个结果：

​

function toJSON(input) {
    return ("{\n" 
           + input.replace(/^(\s*)\[("[^"]*")](\s*)=/gm, "$1$2$3:")
                  .replace(/\{(.*)}(,?)[ \t]*$/gm, "[$1]$2")
           + "\n}").replace(/,(\s*\})/g, "$1");
}

// Demo on the example:
let input = `["'Your Cut'"] = {
    ["id"]                  = 3400,
    ["tier"]                = 1,
    ["type"]                = {"Distributed"},
    ["limit"]               = "Only granted by {{cai|Death from Below|Pyke}}.",
    ["maps"] = {
        ["sr"]              = true,
        ["ha"]              = true,
        ["nb"]              = true,
        ["tt"]              = true,
        ["cs"]              = false,
    },
    ["effects"] = {
        ["consume"]         = "Grants {{g|text=*none*}}{{pp|100;112;140;176;220;274;300|-7+x;0+|type=target's kill bounty|color=gold}}, increased by {{g|100}} for [[First Blood]]. '''Can be used while [[dead]].'''",
    },
},
["Abyssal Mask"] = {
    ["id"]                  = 8020,
    ["tier"]                = 3,
    ["maps"] = {
        ["sr"]              = true,
        ["ha"]              = true,
        ["nb"]              = true,
    },
    ["menu"] = {
        ["tank"]            = true,
    },
    ["stats"] = {

        ["hp"]              = 450,
        ["mr"]              = 35,
    },
    ["effects"] = {
        ["pass"] = {
            ["name"]        = "Unmake",
            ["unique"]      = true,
            ["description"] = "Enemy champions within {{tt|550 units|center to edge}} of you become cursed, reducing their {{as|magic resistance by 5}} {{as|(+ {{fd|1.2}}% '''bonus''' health)}}, capped at a reduction of {{as|25 magic resistance}}. Gain {{as|9 '''bonus''' magic resistance}} per cursed enemy.",
        },
    },
    ["recipe"]              = {"Kindlegem", "Spectre's Cowl"},
    ["buy"]                 = 2700,
},
["Aegis of the Legion"] = {
    ["id"]                  = 3105,
    ["tier"]                = 2,
    ["maps"] = {
        ["sr"]              = true,
        ["ha"]              = true,
        ["nb"]              = true,
    },
    ["menu"] = {
        ["tank"]            = true,
        ["support"]         = true,
    },
    ["stats"] = {
        ["ah"]              = 10,
        ["armor"]           = 30,
        ["mr"]              = 30,
    },
    ["recipe"]              = {"Null-Magic Mantle", "Cloth Armor"},
    ["buy"]                 = 1400,
},`;

const json = toJSON(input);
console.log(JSON.parse(json));
