How to get the request body off of a https get request using node js

Question

I am making a get request using https and aws4 in node js. I know it works because my post request works, but for the life of me I can't figure out how to get the GET request body. I need to put the request body of the GET response in a variable.

The StatusCurrent function is where i need to get the response sent back by the GET Request.

Any help would be greatly appreciated.

const Alexa = require("ask-sdk-core");
var https = require("https");
var aws4 = require("aws4");

function request(opts) {
  https
    .request(opts, function (res) {
      res.pipe(process.stdout);
      // IS THIS WHERE I GET THE REQUEST BODY, BUT HOW
      // I NEED TO PUT IT IN A VARIABLE
    })
    .end(opts.body || "");
}

function lightbulb(status) {
  var load = JSON.stringify({
    state: {
      desired: {
        on: status,
      },
    },
  });

  request(
    aws4.sign(
      {
        hostname: "obsf-ats.iot.us-east-1.amazonaws.com",
        service: "iotdata",
        region: "us-east-1",
        method: "POST",
        path: "/things/esp8266_7F3B95/shadow",
        headers: {
          "Content-Type": "application/json0",
        },
        body: load,
      },
      {
        secretAccessKey: "",
        accessKeyId: "obsf",
      }
    )
  );
}

function statusCurrent() {
  request(
    aws4.sign(
      {
        hostname: "obsf-ats.iot.us-east-1.amazonaws.com",
        service: "iotdata",
        region: "us-east-1",
        method: "GET",
        path: "/things/esp8266_7F3B95/shadow",
        headers: {
          "Content-Type": "application/json0",
        },
      },
      {
        secretAccessKey: "",
        accessKeyId: "osbf",
      }
    )
  );
}

based on the answer this is the request repsonse I get back but I can't access the state with body.state

const httpGet = url => {
  return new Promise((resolve, reject) => {
    http.get(url, res => {
      res.setEncoding('utf8');
      let body = ''; 
      res.on('data', chunk => body += chunk);
      res.on('end', () => resolve(body));
    }).on('error', reject);
  });
};

see https://stackoverflow.com/a/50244236/2142490

I'd expect it to be the same for https

UPDATE: so i'd try

function request(opts) {
  https
    .request(opts, function (res) {

      // IS THIS WHERE I GET THE REQUEST BODY, BUT HOW
      // I NEED TO PUT IT IN A VARIABLE
      res.setEncoding('utf8');
      let body = ''; 
      res.on('data', chunk => body += chunk);
      res.on('end', () => {
          
          console.log(body);
          let json = JSON.parse(body);
          console.log(json.state);

      }
    })
    .end(opts.body || "");
}
