如何解析这种非标准的 JSON 格式？

Question

I want to know some process information ran on the VPS with PM2. But, with the JSON string return by PM2, we can't run JSON.parse() because the JSON is broken.

An example of what PM2 returns:

'{data: 0, informations: "hello", name: "test"}'

But, if you know how the JSON.parse work, you know the problem. We can't parse this string.

Do you have idea to resolve this problem with another function?

Thanks in advance.

Answer 1

It seems like your string is encoded in regular JavaScript or JSON5. JSON5 is a library which allows JSON to be defined in a similar way you would use it in regular JavaScript (without unnecessary " , etc.). Install the library and parse the string with JSON5.parse() . Reference: https://json5.org/

Here is a solution for your specific non-json format. The trick is to make sure to have double quotes around keys...

 function customParse(string){ return JSON.parse(string.replace(/\s|"/g, '') // Removes all spaces and double quotes.replace(/(\w+)/g, '"$1"') // Adds double quotes everywhere.replace(/"(\d+)"/g, '$1') // Removes double quotes around integers ) } // Testing the function let PM2_string = '{data: 0, informations: "hello", name: "test"}' let PM2_obj = customParse(PM2_string) // Result console.log(PM2_obj) console.log(PM2_obj.data) console.log(PM2_obj.informations) console.log(PM2_obj.name)
