Question

execute an ajax request without including any authentication headers

I am looking to create an ajax call with authorization headers only when the user enters a username and password. If these variables are empty, I need to create an ajax call without authorization headers. Is it possible to achieve this using just one ajax call, or do I need to create two separate ajax calls for each scenario?

var username = "user123";
var password = "pass123";

//var username = "";
//var password = "";    

$.ajax({
        type: "GET",
        url: url_survey,
        dataType: "json",
        headers: {
        'Authorization': "Basic " + btoa(username + ":" + password)
        },
        success: 
          function (data) {
            alert("SUCCESS");
       },
        error:
          function (data) {
            alert("ERROR");
          }
      });

Consider the following solution:

let username = "user123";
let password = "pass123";

//let username = "";
//let password = "";    
let headers = {}; //list of headers

if(username && password) //checks if user and pass exist
    headers['Authorization'] = "Basic " + btoa(username + ":" + password);

$.ajax({
        type: "GET",
        url: url_survey,
        dataType: "json",
        headers: headers, //utilizing custom headers
        success: 
          function (data) {
            alert("SUCCESS");
       },
        error:
          function (data) {
            alert("ERROR");
          }
      });

The object passed as a parameter to the $.ajax function holds all the necessary information for making an AJAX call. Simply define this object, add the required properties, and then pass it to the `$.ajax` function.

var ajaxParams = {
    type: "POST",
    url: api_endpoint,
    dataType: "json",
    success: 
      function (response) {
        console.log("Request successful");
    },
    error:
      function (error) {
        console.error("An error occurred");
    }
};

if(token){
    ajaxParams.headers = {
        'Authorization': "Bearer " + token
    };
}

$.ajax(ajaxParams);
