Question

我有一个字符串来描述一个对象，并想将它转换成一个 JS 对象。

字符串：

{
    "platform": "desktop",
    pageName: "JD Sports - Nike Air Force 1  07 LV8 Herren", //Page Title
    pageType: "product", //Page Type
    plu: "16085947_jdsportsde", //Product Code
    description: "Nike Air Force 1  07 LV8 Herren", //Product Name
    unitPrice: "110.00", //Product Price
                    category: "Herren \u003E Herrenschuhe \u003E Sneakers", //End level category
    categoryId: "jdsportsde_ct81275jdsportsde_ct81279jdsportsde_ct81356jdsportsde", //End level category Id
            sale: false, //is on sale? true/false
    brand: "Nike", //Product Brand
    ownbrand: false, //own brand product? true/false
    exclusive: false, //exclusive product? true/false
    onlineexlusive: false, //online exlcusive product? true/false
    currency:"EUR",
    variants: [
                                                            {
                            name:"41",
                            upc: "0194501189583",
                            page_id_variant: "16085947_jdsportsde.0194501189583"
                    }
                                    ,                       {
                            name:"42.5",
                            upc: "0194501189606",
                            page_id_variant: "16085947_jdsportsde.0194501189606"
                    }
                                    ,                       {
                            name:"45",
                            upc: "0194501189644",
                            page_id_variant: "16085947_jdsportsde.0194501189644"
                    }
                                    ,                       {
                            name:"47",
                            upc: "0194501189675",
                            page_id_variant: "16085947_jdsportsde.0194501189675"
                    }
                                    ,                       {
                            name:"47.5",
                            upc: "0194501189682",
                            page_id_variant: "16085947_jdsportsde.0194501189682"
                    }
                                    ,                       {
                            name:"48.5",
                            upc: "0194501189699",
                            page_id_variant: "16085947_jdsportsde.0194501189699"
                    }
                                    ,                       {
                            name:"L",
                            upc: "0194501189569",
                            page_id_variant: "16085947_jdsportsde.0194501189569"
                    }
    ]
};

因为键不在引号中并且由于注释我不能使用 JSON.parse() 如何将我的字符串转换为对象？

它看起来更像是真正的 JavaScript，而不是 JSON。

虽然它通常被认为是 evil，但您可以使用 eval 来解析（并执行！）它，冒着运行不受控制的脚本的风险，无论是在您的用户的浏览器或在您的后端：

var str = `{
    "platform": "desktop",
    pageName: "JD Sports - Nike Air Force 1  07 LV8 Herren", //Page Title
    pageType: "product", //Page Type
    plu: "16085947_jdsportsde", //Product Code
    description: "Nike Air Force 1  07 LV8 Herren", //Product Name
    unitPrice: "110.00", //Product Price
                    category: "Herren \u003E Herrenschuhe \u003E Sneakers", //End level category
    categoryId: "jdsportsde_ct81275jdsportsde_ct81279jdsportsde_ct81356jdsportsde", //End level category Id
            sale: false, //is on sale? true/false
    brand: "Nike", //Product Brand
    ownbrand: false, //own brand product? true/false
    exclusive: false, //exclusive product? true/false
    onlineexlusive: false, //online exlcusive product? true/false
    currency:"EUR",
    variants: [
                                                            {
                            name:"41",
                            upc: "0194501189583",
                            page_id_variant: "16085947_jdsportsde.0194501189583"
                    }
                                    ,                       {
                            name:"42.5",
                            upc: "0194501189606",
                            page_id_variant: "16085947_jdsportsde.0194501189606"
                    }
                                    ,                       {
                            name:"45",
                            upc: "0194501189644",
                            page_id_variant: "16085947_jdsportsde.0194501189644"
                    }
                                    ,                       {
                            name:"47",
                            upc: "0194501189675",
                            page_id_variant: "16085947_jdsportsde.0194501189675"
                    }
                                    ,                       {
                            name:"47.5",
                            upc: "0194501189682",
                            page_id_variant: "16085947_jdsportsde.0194501189682"
                    }
                                    ,                       {
                            name:"48.5",
                            upc: "0194501189699",
                            page_id_variant: "16085947_jdsportsde.0194501189699"
                    }
                                    ,                       {
                            name:"L",
                            upc: "0194501189569",
                            page_id_variant: "16085947_jdsportsde.0194501189569"
                    }
                    ]
};`;

eval("obj = " + str);
console.log(obj.pageName);

Answer 2

首先，如果您绝对信任源代码，则可以使用 eval，因为它看起来更像 JS 而不是 JSON！换句话说，除非您 100% 确定，否则不要这样做。

var s = `{
    "platform": "desktop",
    pageName: "JD Sports - Nike Air Force 1  07 LV8 Herren", //Page Title
    pageType: "product", //Page Type
    plu: "16085947_jdsportsde", //Product Code
    description: "Nike Air Force 1  07 LV8 Herren" //Product Name
}`;
var obj;

eval('obj = ' + s);
console.log(obj.pageType);

// and convert it to valid JSON
var json = JSON.stringify(obj);
console.log('JSON: ', json);

Answer 3

最好的解决方案是修复为您提供此字符串的代码，而不是在创建后尝试处理格式错误的字符串。更喜欢解决原因而不是结果。

如果这是不可能的，或者由于任何原因您不想这样做，那么唯一的解决方案就是使用一个小技巧：

const string = `{
    "platform": "desktop",
    pageName: "JD Sports - Nike Air Force 1  07 LV8 Herren", //Page Title
    pageType: "product", //Page Type
    plu: "16085947_jdsportsde", //Product Code
    description: "Nike Air Force 1  07 LV8 Herren", //Product Name
    unitPrice: "110.00", //Product Price
                    category: "Herren > Herrenschuhe > Sneakers", //End level category
    categoryId: "jdsportsde_ct81275jdsportsde_ct81279jdsportsde_ct81356jdsportsde", //End level category Id
            sale: false, //is on sale? true/false
    brand: "Nike", //Product Brand
    ownbrand: false, //own brand product? true/false
    exclusive: false, //exclusive product? true/false
    onlineexlusive: false, //online exlcusive product? true/false
    currency:"EUR",
    variants: [
                                                            {
                            name:"41",
                            upc: "0194501189583",
                            page_id_variant: "16085947_jdsportsde.0194501189583"
                    }
                                    ,                       {
                            name:"42.5",
                            upc: "0194501189606",
                            page_id_variant: "16085947_jdsportsde.0194501189606"
                    }
                                    ,                       {
                            name:"45",
                            upc: "0194501189644",
                            page_id_variant: "16085947_jdsportsde.0194501189644"
                    }
                                    ,                       {
                            name:"47",
                            upc: "0194501189675",
                            page_id_variant: "16085947_jdsportsde.0194501189675"
                    }
                                    ,                       {
                            name:"47.5",
                            upc: "0194501189682",
                            page_id_variant: "16085947_jdsportsde.0194501189682"
                    }
                                    ,                       {
                            name:"48.5",
                            upc: "0194501189699",
                            page_id_variant: "16085947_jdsportsde.0194501189699"
                    }
                                    ,                       {
                            name:"L",
                            upc: "0194501189569",
                            page_id_variant: "16085947_jdsportsde.0194501189569"
                    }
                    ]};`
let object

eval("object = " + string)

这将创建一个基于 string 的对象。
