How to get BingAPIs-Market response header

Question

We have a scenario where we need to show the Bing Market/ Region from where the Bing news is being fetched. In the response headers, I am able to see BingAPIs-Market.

1. I am getting empty object as response headers. Do we need to add any request headers to get response headers
2. Is there any API to fetch BingAPIs-Market response header

Answer 1

Here's a sample code to fetch the headers. Hope this helps.

const fetch = require("node-fetch");
var myHeaders = new fetch.Headers();
myHeaders.append("Ocp-Apim-Subscription-Key", "ENTER YOUR KEY");

var requestOptions = {
  method: 'GET',
  headers: myHeaders,
  redirect: 'follow'
};

// search results
fetch("https://api.bing.microsoft.com/v7.0/news/search?q=microsoft", requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log('error', error));

// response headers
fetch("https://api.bing.microsoft.com/v7.0/news/search?q=microsoft", requestOptions)
  .then(response => response.headers)
  .then(result => console.log(result))
  .catch(error => console.log('error', error));

// BingAPIs-Market
fetch("https://api.bing.microsoft.com/v7.0/news/search?q=microsoft", requestOptions)
  .then(response => response.headers.get('bingapis-market'))
  .then(result => console.log(result))
  .catch(error => console.log('error', error));

Answer 2

Quick follow-up on your second question. Users can only pass Market as a query parameter to get results only from that market, and can get market used by the API request as BingAPIs-Market Header. Please refer to the following documents (response objects, headers) for more details. Hope this helps!
