Hello,

I have developed a web application using Xtext. This application makes HTTP calls to an API using axios, both from the front end and the back end. To enhance security, I have decided to implement a Keycloak adapter for the front end.

Now, I need to figure out how to pass the idToken from the front end to the back end. Can you please provide guidance on this?

maybe you can try to override the sendRequest method using javascript means or you directly patch the xtext js files


(i am not a javascript wizard)
require(["webjars/ace/1.3.3/src/ace"], function() {
			require(["xtext/xtext-ace"], function(xtext) {
				
				var cs = xtext.createServices;
				if (cs) {
					xtext.createServices = function(editor, options) {
						const s = cs.call(this, editor, options);
						for (const property in s) {
							const oldSendRequest = s[property].sendRequest;
							if (oldSendRequest) {
								 editor.xtextServices[property].sendRequest = function(editorContext, settings, needsSession) {
								 	self = this;
								 	settings.data.dullydully="Hello";
								 	oldSendRequest.call(self, editorContext, settings, needsSession);
								 }
							}
						}
						return s;
					}
				}
			
				var editor = xtext.createEditor({
					baseUrl: baseUrl,
					syntaxDefinition: "xtext-resources/generated/mode-mydsl"
				});
				
			});
		});


or does the token need to be send in header?

then maybe something like

//assuming this does not strip anything, otherwise maybe call original beforeSend
settings.beforeSend = function(xhr){xhr.setRequestHeader('X-Test-Header', 'test-value');};


maybe you can also do it globally with

$.ajaxSetup({
				    beforeSend: function(xhr) {
				        xhr.setRequestHeader('X-Test-Header', '...');
				    }
				});
