Is there a way I can call an API from an api in express the parameter value in axios is undefined how do i add parameters in axios from a variable

Question

**I tried passing in a parameter to my route and then passing that parameter to the variable axios with the url. The request succeeds if I remove the params object and instead hardcode the parameter in the url.

I am trying to post the question, but my word is little and the code is too much. I don't know how I can solve this so the explanation is enough to solve the question. I have explained it to the best of my ability. the code can tell much for itself. Thank you.

const axios = require("axios");
dotenv.config();
const Url = "https://api.dhl.com/location-finder/v1/find-by-address";
exports.getLocation = (req, res, next) => {
  const country = req.body.countryCode;
  axios
    .get(Url, {
      params: {
        countryCode: country}
      ,headers: {'DHL-API-Key': process.env.LOCATOR_API_KEY}})
    .then(function (response) {
      console.log(response.data);
    })
    .catch(function (error) {
      console.log(error);
    });
};```

**THIS IS THE CONSOLE LOG THE PARAMETER PART IS UNDEFINED HOW WILL I ADD THE PARAMETER

It is a breaking change from axios version 0.19. If you would like to add a parameter to a request you have to pass it via an interceptor. As example:

const axios = require('axios');
// api openexchange
const oexchange = axios.create({
  baseURL: 'https://openexchangerates.org/api/',
  timeout: parseInt(process.env.TIMEOUTEXTERNALREQUEST)
})
oexchange.interceptors.request.use((config) => {
  config.params = config.params || {};
  config.params.app_id = process.env.OPENEXCHANGEAPITOKEN // <-- here add the query params in your case it will be countryCode
  return config;
});

exports.cotacao = async (req, res) => {
  try {
    req.oexchange = await oexchange.get('latest.json') //here i'm calling external api with query params added in interceptor
    return res.status(200).json(req.oexchange.data)
  } catch (e) {
    res.status(500).json({errors: [{ location: 'cotacao', msg: 'Houve um erro ao acessar a api do open exchange.', param: 'openexchangerates' }]})
  }
}

It is a know behavior that was added in version 0.19 (May 30, 2019) Currently there is a community effort to fix that behavior you can follow here , it is addressed to be fixed in release 0.20.

If you would like the old way of passing in url params you should use version 0.18 backwards.

Every code here is based in axios documentation
