Parse the JSON value.

Hi Everyone, 

I am retting response body when I am calling REST message inside script include 

 var r = new sn_ws.RESTMessageV2('custom rest messge, 'Post Credentials');
            r.setRequestHeader('Content-Type', 'application/json');
            r.setStringParameter('email', sys_email);
            r.setStringParameter('password', sys_pwd);
            var response = r.execute();
            var responseBody = response.getBody(); // This is the response getting back from API
            gs.info("REST = " + responseBody);
            var httpStatus = response.getStatusCode();

Response body :

{
    "message": "Successfully Logged in",
    "token": {
        "idToken": "eyJhbGciOiJSUzI1NiIsImtpZCI6IjFlNTIxYmY1ZjdhNDAwOGMzYmQ3MjFmMzk2OTcwOWI1MzY0MzA5NjEiLCJ0eXAiOiJKV1QifQ.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.T5nK8mf_XNJBCsQmXW9eVx_rHtIiQU9KlyYjcMBpdsNfrc8UDZkqcrBEC0LP8C9KLADpY8f9_R0O0C22BKMmOZVoavZ1yQIfxPwsk7EXCwfN_XyvAND1GyDfWYhQW0QR1cuPYkGZXyk-4ZdopKycSqxRC_Cj8RT36zvSvmYux4ve5AXMYrD-2C55EG8fifVfpR2SPh8HJQW0qzSur4NC35D8elDKpg7W5q2FCkeh8V6tCV70oOpLU-cvN8Stq4qfDP0XFlrKb0eJ1Ax2KU2mxXUPJRSgE9Yj7OvVrQQwXw8IGd27vQxaFHPyWDcmeVRuhimTjlM9l_TP3Fnul2ZLGQ",

    },

I want to get value of idtoken from this response body and return it to UI action. How can I parse this JSON object.

Thanks in advance

Hello @Abhijit Das7 

Here is the updated script:

var r = new sn_ws.RESTMessageV2('custom rest message', 'Post Credentials');
r.setRequestHeader('Content-Type', 'application/json');
r.setStringParameter('email', sys_email);
r.setStringParameter('password', sys_pwd);

var response = r.execute();
var responseBody = response.getBody(); // This is the response getting back from API
var httpStatus = response.getStatusCode();

if (httpStatus == 200) { // Check if the request was successful
    try {
        var responseJson = JSON.parse(responseBody); // Parse the JSON response
        var idToken = responseJson.token.idToken; // Extract the idToken
        gs.info("Extracted idToken: " + idToken);
        return idToken; // Return the idToken to be used in your UI action or elsewhere
    } catch (error) {
        gs.error("Error parsing JSON response: " + error.message);
        return null;
    }
} else {
    gs.error("Failed to fetch REST response. HTTP Status: " + httpStatus);
    return null;
}

Hope this helps!
