How to parsing the correct values from a json decoding [duplicate]

Question

Hii ha ve written this question because i have a json converted to a string with a function of php called json_encode()

Something like this:

{ "data":"2","state":"false"}

when the original json that im trying to encode is like this:

{ "data":2,"state":false}

(Please note that the type of the variables are different, in the original i have an int number called data and boolean called state, but when i use json_encode() every variable goes to a string..)

The problem is when i try to json.PARSE() the value from the json encode of php in angular i don´t get the correct value, every variable is a string...

For example, isntead of getting the boolean state of the variable, i get "false" or "true", and this is a problem...

There is a way to parse this avoiding this problem? basically my problem is when i parse the json in my angular project i dont get the correct type of variable..

Thanks!

Proper JSON would be: "{\"data\":2,\"state\":false}"; JSON does not handle single-quoted strings. — Mr. Polywhirl

Could you clarify your question? Assuming you mean: input: { "data": 2, "state": false} desired output: { "data": "2", "state": "false" } — Josh Mathews

@Hollyol is exactly like that, but when i json.parse in angular i dont get the real values, i get just a string, instead of getting false as a boolean, i get "false" as a string. — Luis Bermúdez

Can you try to pass the object to PHP as a string using JSON.stringify() from javascript ? I think it would do the trick — Xapadoan

You can use JSON.parse on an individual value to convert it into the desired type:

const oldValue = JSON.parse('{"data":"2","state":"false"}')

const result = {}

Object.keys(oldValue).forEach(key => {
  result[key] = JSON.parse(oldValue[key]);
});

Here's the other way around:

const oldValue = JSON.parse('{"data": 2,"state": false}');

const result = {}

Object.keys(oldValue).forEach(key => {
  result[key] = oldValue[key].toString();
});

Note: These examples assume flat objects. You'd need to recurse through the object's tree if some of the values are objects, for example {a: {b: "c"}}.
