The following example shows how to make a REST API call to get folder information from ann HTML page:
<html>
<head>
function UserAction() {
var xhttp = new XMLHttpRequest();
xhttp.open("GET", "https://docs-xxxxxx.documents.us2.oraclecloud.com//documents/api/1.1/folders/FDE2F2015454AB1596AF3404090B9CFF7042366FBD9C", false);
xhttp.setRequestHeader("Accept", "application/json, text/plain, */*");
xhttp.setRequestHeader("Authorization", "Basic " + btoa(document.getElementById('u').value + ':' + document.getElementById('p').value ));
xhttp.send();
alert( document.getElementById('u').value );
var response = JSON.parse(xhttp.responseText);
alert(response.ownedBy.displayName);
}
</head>
<body>
<form>
User name:<br>
<input type="text" name="username" id="u"><br>
User password:<br>
<input type="password" name="psw" id="p">
</form>
<button type="submit" onclick="UserAction()">Search</button>
</body>
</html>
Enjoy 😉
