Answer 1

Create a PHP file.here file name is chat.php

<?php
if(isset($_POST['conversation'])) {
$data = array("input"=>array("text"=>$_POST["conversation"]));
$url = "https://gateway.watsonplatform.net/conversation/api/v1/workspaces/a9379972-d820-4cdf-b1cb-ad0af898a534/message?version=2016-07-11";
$ch = curl_init($url);
curl_setopt_array($ch, array(
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_USERPWD => "username:password",
    CURLOPT_HTTPHEADER => array("Content-Type:application/json"),
    CURLOPT_POSTFIELDS => json_encode($data),
));
$response = curl_exec($ch);
curl_close($ch);
print_r(json_decode($response));
 }
 ?>

and call this by using Ajax

var xhr = new XMLHttpRequest();
//xhr.open('get', 'chat.php');
xhr.open("GET", "chat.php?data=" + data to be pass, false);
// Track the state changes of the request.
xhr.onreadystatechange = function () {
var DONE = 4; // readyState 4 means the request is done.
var OK = 200; // status 200 is a successful return.
if (xhr.readyState === DONE) {
    if (xhr.status === OK) {
        //alert(xhr.responseText); 
        talking = true;
        botMessage=xhr.responseText;// 'This is the returned text.'
    } else {
        // console.log('Error: ' + xhr.status); // An error occurred during the request.
        alert ('Error: ' + xhr.status);
    }
}
};

 // Send the request to send-ajax-data.php
 xhr.send();
