不在数组中的脏JSON对象-如何解析呢？

Question

I'm currently trying to parse the following JSON output. These JSON objects are stored in one big string and not in a JSON array. As such it is not valid JSON.

{"output": "te\ns\nt"}
{"output": "test"}

This string also contains multiple new lines. So splitting on new lines is not an option.

Nevertheless is there any way of parsing this invalid JSON that it results in a valid array of JSON objects?

Answer 1

If your object-list (let's call it that) contains valid objects you can first make an array from each line and then go through that array and parse the JSON:

 let data = `{"output": "test"} {"output": "test"}`; //template string to make the newlines work flawless... // first split on newline filter out "" map to the parsed JSON data = data.replace(/}\\n*/g, "}**").split("**") .filter(Boolean) .map(JSON.parse); console.log(data); 

Answer 2

Here's something dirty that might work.

let string = `{"output": "te\ns\nt"}
{"output": "test"}`

let json = JSON.parse(`[${string.replace(/}[\s]*\{/g, '}, {').replace(/\n/g, '\\n')}]`)

console.log(json) // [ { output: 'te\ns\nt' }, { output: 'test' } ]

Not pretty and quite fragile, but quick.
