How do I parse a json response from a GET request

Question

How do I go about parsing this json response so I can grab the email_address keys and their respective values. it is being returned in this function. I have tried response.content.email_address which just returns undefined. It must be really simple, I just can't seem to parse it properly.

Thanks

function (error, response) {
  if ( error ) {
    console.log( error );
  } else {
    console.log( response );
  }

Answer 1

You can use JSON.parse(response) You can then save it in a variable so you can access the data from there.

function(error, response) {
  if (error) {
    console.log(error);
  } else {
    var data = JSON.parse(response);
    console.log(data.content.email_address) // This should print the value
  };
});

I had to end up doing something like this to get one of the email addresses, so i guess I will have to run a for loop or something to get all of them.

var data = JSON.parse(response.content);
var dataParsed = data.results[0].email_addresses[0].email_address;
