JSON.stringify是否在属性上没有引号? [英] JSON.stringify without quotes on properties?

问题描述

我正在使用使用不正确的JSON格式的服务(属性周围没有双引号).所以我需要发送

I'm using a service which uses incorrect JSON format (no double quotes around properties). So I need to send

{ name: "John Smith" }而不是{ "name": "John Smith" }

无法更改此格式，因为这不是我的服务.

This format cannot be changed as this is not my service.

是否有人知道像上面那样格式化JavaScript对象的字符串化路由?

Anyone know of a stringify routing to format an JavaScript object like above?

推荐答案

var json = '{ "name": "John Smith" }';       //Let's say you got this
json = json.replace(/\"([^(\")"]+)\":/g,"$1:");  //This will remove all the quotes
json;                                        //'{ name: "John Smith" }'

正则表达式将删除所有引号，最重要的是，它不需要库！

The regex will remove all the quotes, and the most important thing is, it does not need a library!

极端情况:

var json = '{ "name": "J\\":ohn Smith" }'
json.replace(/\\"/g,"\uFFFF"); //U+ FFFF
json = json.replace(/\"([^"]+)\":/g,"$1:").replace(/\uFFFF/g,"\\\"");
//'{ name: "J\":ohn Smith" }'

特别感谢Rob W修复它.

Special thanks to Rob W for fixing it.

更新:

在正常情况下，上述正则表达式可以使用，但是从数学上讲，不可能用正则表达式描述JSON格式，使其在每种情况下都可以使用(使用正则表达式无法计算相同数量的大括号.) ，我创建了一个新函数来删除引号，方法是通过本机函数正式解析JSON字符串并重新序列化它:

In normal cases the aforementioned regexp will work, but mathematically it is impossible to describe the JSON format with a regular expression such that it will work in every single cases (counting the same number of curly brackets is impossible with regexp.) Therefore, I have create a new function to remove quotes by formally parsing the JSON string via native function and reserialize it:

function stringify(obj_from_json){
    if(typeof obj_from_json !== "object" || Array.isArray(obj_from_json)){
        // not an object, stringify using native function
        return JSON.stringify(obj_from_json);
    }
    // Implements recursive object serialization according to JSON spec
    // but without quotes around the keys.
    let props = Object
        .keys(obj_from_json)
        .map(key => `${key}:${stringify(obj_from_json[key])}`)
        .join(",");
    return `{${props}}`;
}
