AngularJS 1.8: implementing $http interceptors modifying requests based on user roles

angularjs http interceptors authentication JavaScript

Does anyone know how to After trying multiple solutions online, I still can't figure this out... I tried several approaches but none seem to work. I'm working with a scenario with $http interceptors in my AngularJS 1.8 application where I need to modify requests based on user roles. I have set up an interceptor that should append a custom header (`X-User-Role`) depending on the userโ€™s role, but it seems the header is not being added as expected. Hereโ€™s what I have implemented so far: ```javascript angular.module('myApp') .factory('authInterceptor', function() { return { request: function(config) { const userRole = getUserRole(); // This function retrieves the user's role if (userRole) { config.headers['X-User-Role'] = userRole; } return config; } }; }) .config(['$httpProvider', function($httpProvider) { $httpProvider.interceptors.push('authInterceptor'); }]); ``` The `getUserRole` function is working fine, and I'm able to log the correct role to the console before the request is sent. However, when I inspect the network requests, the `X-User-Role` header is missing. I even tried adding a debug statement inside the interceptor to ensure that itโ€™s being called, and it is, but the modification does not seem to take effect. I also tried removing other interceptors to see if there was a conflict, but this did not resolve the scenario. On one occasion, I received a warning in the console stating: `Warning: $http request failed with status 401`, which suggests that the server might be rejecting the request due to the missing role header. Could this be a timing scenario where the interceptor is not modifying the request in time? How can I troubleshoot this further and ensure the header is appended properly? Any insights or suggestions would be greatly appreciated! I'm working on a CLI tool that needs to handle this. Is there a better approach? What am I doing wrong? I'm on Windows 10 using the latest version of Javascript.
