How to get session token on a ui page with direct=true

token.xhtml

<!--- In a ui page -->
<!-- this will get the token on the server side and set it to a client-side javascript variable.
<g:evaluate object="true">
  var g_ck = gs.getSessionToken();
</g:evaluate>
<script>
  window.g_ck = "$[g_ck]";
</script>

<!-- In your AngularJS config, you can set the token as a default $httpProvider header -->
<!-- This isn't good if you are making $http calls to other endpoints besides SN -->
angular.module("app").run(function ($http) {
  $http.defaults.headers.get = {
    'X-UserToken' : window.g_ck
  };
});

<!-- In a single $http call, you can specify the token in the config options of the call -->
$http.get("url",{ headers : { "X-UserToken" : window.g_ck}}).then(function(response, result){});
