I can't do a request that needs to set a header with axios

Question

I'm trying to get some datas from an external API (from Mashape) that requires a specific header to set the API key.

Everything is ok using jQuery :

$.ajax({
    url: 'https://omgvamp-hearthstone-v1.p.mashape.com/cardbacks',
    type: 'GET',
    data: {},
    dataType: 'json',
    success: function(data) { console.dir((data.source)); },
    error: function(err) { alert(err); },
    beforeSend: function(xhr) {
    xhr.setRequestHeader("X-Mashape-Authorization", "MY_API_KEY");
    }
});

However, when I'm trying to do the same request with axios for a react application, I have a 404 error:

axios.get({
  url: 'https://omgvamp-hearthstone-v1.p.mashape.com/cardbacks',
  headers: {
      "X-Mashape-Authorization": "MY_API_KEY"
   }
 })

Is there something I'm missing ? Thanks.

Answer 1

I finally understood.

We need to set the header BEFORE the request using axios.defaults.headers.common['header_name'] = "API_KEY"; :

axios.defaults.baseURL = 'https://omgvamp-hearthstone-v1.p.mashape.com';
axios.defaults.headers.common['X-Mashape-Key'] = "API_KEY";
axios.get('/cardbacks')
    .then((resp) => {
        console.dir(resp);
    });
