How to parse string into an array of objects?

Question

I have a python app that send a strange array of objects to my node js app in string format like this :

"[{'foo':'bar'},{'hello':'world'}]"

I am trying to parse it with JSON.parse() but I get errors :

SyntaxError: Unexpected token ' in JSON at position 1

On python side the array is recognized as a true array list but when I pass it to nodejs with python shell , this become a stringified array of objects.

Any suggestion to parse it ?

Answer 1

JSON.parse() will not accept single quotes as string boundaries. This string, using double quotes, works fine:

 console.log(JSON.parse('[{"foo":"bar"},{"hello":"world"}]'));

If it is impossible to change the Python app, you may replace the single quotes to double quotes before JSON parsing the string.

Answer 2

How about using json.load()?

import json
inp = "[{'foo':'bar'},{'hello':'world'}]"

a = json.loads(inp.replace("'",'"'))

print(a)

Output (list of dictionaries) :

[{'foo': 'bar'}, {'hello': 'world'}]
