I'm very newbie in AngularJS, and now spending 3 days in finding a way to handle 401 status. I've tried interceptors, using $http, using $resource...but nothing is working. My app calls JSONP call on the same server. when error occurs it is caught in error callback function. but the status is always 0 and the response is undefined.
First, I tried this interceptor
app.config(['$httpProvider', function($httpProvider) {
$httpProvider.responseInterceptors.push(['$q', function($q) {
return function(promise) {
return promise.then(function(response) {
console.log('success in interceptor');
return response;
}, function(response) {
console.log('error in interceptor');
console.log(response);
if (response.status === 401) {
response.data = {
status: false,
description: 'Authentication required!'
};
return response;
}
return $q.reject(response);
});
}
}]);
}]);
Second, also tried in controllers using $resource
$scope.fetchData = function(fromDate, toDate){
Cancel.get({from: fromDate, to: toDate, perPage: 99999},
function(data){
$scope.cancels = $scope.filteredCancels = data.data;
$scope.search();
},
function(response) {
$scope.errorMessage = '<h4>Error : '+response.status+'</h4>';
window.location = "/";
});
};
Third, tried using $http instead of $resource
$scope.fetchData = function(fromDate, toDate){
$http.jsonp('http://host:8900/api/cancellations?callback=JSON_CALLBACK')
.success(function(data, status, headers, config) {
console.log(status);
})
.error(function(data, status, headers, config) {
console.log(status);
};
Here is header information for the JSONP call

I couldn't find a way to handle the unauthorized status 401, I tied all the things though. It would be very appreciated if I can get a tip or kind advice.
The accepted answer doesn't work for later versions of angular. Using 1.5.x (and maybe even earlier) you need to write the interceptor differently:
// http interceptor to handle redirection to login on 401 response from API
app.factory('httpResponseInterceptor', ['$q', '$rootScope', '$location', function($q, $rootScope, $location) {
return {
responseError: function(rejection) {
if (rejection.status === 401) {
// Something like below:
$location.path('signin/invalidSession');
}
return $q.reject(rejection);
}
};
}]);
Apply with:
app.config(function($httpProvider) {
$httpProvider.interceptors.push('httpResponseInterceptor');
});
