Remove back slashes from JSON response

Question

I am getting the JSON error response from server in the following way,

let err = {
        "_body": "{\"error\":\"264\",\"message\":\"Please enter valid usename/password\",\"object\":null}",
        "status": 400,
        "ok": false
    }

And i want to display the error message on the screen 'Please enter valid usename/password'

I tried in the following way but no luck,

console.log((this.err._body).replace(/\\/g, ''));

Answer 1

You just need to deserialize the body.

let err = {
        "_body": "{\"error\":\"264\",\"message\":\"Please enter valid usename/password\",\"object\":null}",
        "status": 400,
        "ok": false
    }

var body = JSON.parse(err._body);
console.log(body.message);

Click on Run code snippet to see this working.

You probably need to decode the wrapped json string again:

let responseBody = JSON.parse(this.err._body);
console.log(responseBody.message);
