Hello,

I would like to access to Apache Atlas via a XmlHtttRequest object. It doesn't work:

Access-Control-Allow-Origin is missing.

Thks for your help.

Try adding CORS related headers here and recompile atlas project.

responseWrapper.setHeader("Access-Control-Allow-Origin", "*"); 
responseWrapper.setHeader("Access-Control-Allow-Methods", "GET, OPTIONS, HEAD, PUT, POST");

This should work.

Hello @Nixon Rodrigues

My snippet code :

<html>
<head>
</head>
<body>
<h1>TEST</h1>
<script type="text/javascript">
    var myTestRequest = function() {
        var myUrl = "http://SERVER_IP:21000/api/atlas/types/";
        //Instantiate HTTP Request
        var request = ((window.XMLHttpRequest) ? new XMLHttpRequest() : new ActiveXObject("Microsoft.XMLHTTP"));
        request.open("GET", myUrl, true);
        request.setRequestHeader("Content-Type","application/json");
        //request.channel.QueryInterface(Components.interfaces.nsIHttpChannel).redirectionLimit = 0;

        request.setRequestHeader("Authorization", "Basic " + btoa("admin:admin"));
        //request.withCredentials = true;
        request.send(null);
    }
</script>
    <div id="myTestRequest" style="display: block">
      <button onclick="myTestRequest()">Login</button>
    </div>
</body>
</html>

Error (in attached file):

XMLHttpRequest cannot load http://SERVER_IP:21000/api/atlas/types/. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://SERVER_IP:8000' is therefore not allowed access. The response had HTTP status code 400.

Thank you for your help.

@Nixon RodriguesThank you so much for your help. It will try it; it should work.

May we shoud notify a JIRA ? Or Pull Request on github for this change.

It should better if we could put this on atlas-application.properties.

Best regards
