JavaScript pCloud API call to fetch userinfo gives an error

Question

While calling the api from JavaScript

This HTTP request works fine https://api.pcloud.com/[email protected]&password=xxxx

In the below code I want to call via JavaScript

var user='email loggin';
var password='password of pcloud';

function make_base_auth(user, password) {
  var tok = user + ':' + password;
  var hash = btoa(tok);
  return "Basic " + hash;
}

$.ajax
  ({
    type: "GET",
    url: "https://api.pcloud.com/userinfo",
    dataType: 'json',
    async: false,
    data: '{}',
    beforeSend: function (xhr){ 
        xhr.setRequestHeader('Authorization', make_base_auth(username, password)); 
    },
    success: function (){
        alert('Working Fine'); 
    }
});

output in console

XMLHttpRequest cannot load https://api.pcloud.com/userinfo?{}. Request header field Authorization is not allowed by Access-Control-Allow-Headers in preflight response.

If someone can provide a solution or enhance the code.

Answer 1

Pass the username and password in the data field and remove the "beforeSend" part. For more information and examples, you can check out the pCloud Javascript SDK: https://github.com/pCloud/pcloud-sdk-js

Here is working example (a bit shorter):

$.getJSON("https://api.pcloud.com/userinfo", {
  username: "***", 
  password: "***"
}, function() {
  alert("working fine"); 
});
