将具有key = value对的字符串解析为JSON [英] Parse string having key=value pairs as JSON

问题描述

我的节点应用接收到一系列格式为"a=x b=y c=z"的字符串(即，包含几个以空格分隔的key=value对的字符串).

My node app receives a series of strings in the format "a=x b=y c=z" (i.e. a string containing several space-separated key=value pairs).

将这样的字符串转换为形式为{a: x, b: y, c: z}的JSON对象的最巧妙的方法是什么?

What is the neatest way of converting such a string into a JSON object of the form {a: x, b: y, c: z}?

我敢打赌，这里有一种解决方案，但还没有找到.

I'm betting that there's a one-line solution, but haven't managed to find it yet.

谢谢.

推荐答案

一种方法是将替换为,，将=替换为::

One way would be to replace the with a , and an = with a ::

var jsonStr = '{' + str.replace(/ /g, ', ').replace(/=/g, ': ') + '}';

或者如果您需要在键和值两边加上引号:

Or if you need quotes around the keys and values:

var jsonStr2 = '{"' + str.replace(/ /g, '", "').replace(/=/g, '": "') + '"}';

JSON.parse()，如果需要的话.

JSON.parse() it if you need.

示例输出:

str:      a=x b=y c=z
jsonStr:  {a: x, b: y, c: z}
jsonStr2: {"a": "x", "b": "y", "c": "z"}
