解析未引用的JSON字符串 [英] Parsing unquoted JSON string
问题描述
解析未引用的JSON字符串最简单的方法是什么?
例如,如果我具有以下条件:
What is the easiest method to parse unquoted JSON string?
for example if I have the following:
{property1:value1,property2:value2}
以下内容引发错误:
JSON.parse( badJSONString );
因为正确的JSON应该带有引用的键和值:{"property1":"value1"}
since proper JSON should have keys and values quoted: {"property1":"value1"}
推荐答案
如果数据是一致的(如果这样的话可能会很大),则可以使用非常简单的函数来处理字符串.对于某些在值中带有逗号或冒号的字符串或'{property1:val:ue1 ,property2:val,ue2}'
这样的字符串,以下操作将失败,但是如果在数据中没有一些定界符,则无论如何它们都会成为问题.
If your data is consistent (and that might be a big if), you can process the string with a very simple function. The following will fail with certain strings that have commas or colons in the values or string like '{property1:val:ue1 ,property2:val,ue2}'
but those are going to be problematic anyway without some delimiters in the data.
let bad = '{property1:value1,property2:value2}'
let obj = bad.slice(1, -1).split(/\s?,\s?/)
.map(item => item.split(':'))
.reduce((a, [key, val]) => Object.assign(a, {[key]: val}), {})
console.log(obj)
