Hi all, good morning. I am coding an Angular2 application and I need to implement Authorization like this example on Keycloak https://github.com/keycloak/keycloak/tree/master/examples/authz/photoz, there are another example that indicates how to use Keycloak on Angular2 applications ( https://github.com/keycloak/keycloak/tree/master/examples/demo-template/a... ) My real problem is how to write responseError on Angular2? Have you ever had this kind of problem? This is the code(red code) that i want to pass to Angular2....please help me. module.factory('authInterceptor', function ($q, $injector, $timeout, Identity) { return { request: function (request) { document.getElementById("output").innerHTML = ''; if (Identity.authorization && Identity.authorization.rpt && request.url. indexOf('/authorize') == -1) { retries = 0; request.headers.Authorization = 'Bearer ' + Identity.authorization.rpt; } else { request.headers.Authorization = 'Bearer ' + Identity.authc.token; } return request; }, responseError: function (rejection) { var status = rejection.status; if (status == 403 || status == 401) { var retry = (!rejection.config.retry || rejection.config.retry < 1); if (!retry) { document.getElementById("output").innerHTML = 'You can not access or perform the requested operation on this resource.'; return $q.reject(rejection); } if (rejection.config.url.indexOf('/authorize') == -1 && retry) { var deferred = $q.defer(); // here is the authorization logic, which tries to obtain an authorization token from the server in case the resource server // returns a 403 or 401. *Identity.authorization.authorize(rejection.headers('WWW-Authenticate')).then(function (rpt) {* * deferred.resolve(rejection);* * }, function () {* * document.getElementById("output").innerHTML = 'You can not access or perform the requested operation on this resource.';* * }, function () {* * document.getElementById("output").innerHTML = 'Unexpected error from server.';* * });* var promise = deferred.promise; return promise.then(function (res) { if (!res.config.retry) { res.config.retry = 1; } else { res.config.retry++; } var $http = $injector.get("$http"); return $http(res.config).then(function (response) { return response; }); }); } } return $q.reject(rejection); } };
