How can I wait for my "request" and response back to front end?

[YuyangZhou3]

Hi guys, I am working on the Zoom API now. I want to send my token from ZOOM API to front-end as a response. However, "token from request" is always printed first and undefined! Then the token from Zoon API" will be followed with the token. How can I make it happend? Thx!

`
const Newrequest = require("request");

class ZoomController {
async getAccessToken({request, response, params}) {

const instructor_id = params.id;
try {
  let tokenRes;
  const code = request.all().code;
  console.log("the code from frontend is ", code);
  const client_id = _something_
  const client_secret = _something_
  var options = {
    method: "POST",
    url: "https://api.zoom.us/oauth/token",
    qs: {
      grant_type: "authorization_code",
      code: code,
      redirect_uri: _something_
    },
    headers: {
      Authorization:
        "Basic " +
        Buffer.from(client_id + ":" + client_secret).toString("base64")
    }
  };

  await Newrequest(options, function(error, res, body) {
    if (error) throw new Error(error);
    tokenRes = JSON.parse(body);
    console.log("token from Zoon API",tokenRes);
  });

  console.log("token from request",tokenRes);
  return response.status(200).send(tokenRes);
} catch (error) {
  console.log(error);
  return response.status(401).send();
}

}

Hey @YuyangZhou3! 👋

Your issue is not related to AdonisJS at all.
You need first to understand how asynchronous code works in JavaScript.

To give you a hint, you are mixing async/await with a callback API.
I'd recommend you to read about Promise and async/await.
